End of the Implementation Trip

Our final week was busy and productive, we had a lot of early morning followed by long days. We returned from our cultural excursion last Sunday to Patriensa with four of our six team members. Dr. Ezekoye and Rahul parted ways with us in Accra. We were sad to see them go, but motivated to finish out strong our last week.  We spent the last week following up with families we had built stoves for and continuing to build stoves for more homes. DeGraft is the PPE manager who is in charge of both the sachet and sawdust initiatives. He came with us to each of the homes and translated for us. By the end of our trip, DeGraft could build the stoves, explain how to use them, and knew how to fix the common problems families encountered when using the stoves. We were so thankful to for DeGraft's help, and we are happy to know that we are leaving a sawdust stove expert in Patriensa. DeGraft told us he plans to follow up with the homes we build stoves for after we leave, and that he plans to help families we did not have time to see build stoves as well. We plan to follow up with DeGraft through email to see how our stoves are being used and to work through problems that come up with him. It was really neat to and to revisit homes that were using our stoves, and to see that people were beginning to gather sawdust on their own.

Our last day, Thursday, was one of the highlights of the trip, we accomplished so much. We started the day by riding in the back of a flat bed truck to pick up the 100 clay bricks we had contracted to be made. It was a bumpy ride through trails that I never would have guessed a truck of that size could fit on. We brought the bricks to village center and unloaded them. After building our first stove, Mike from KNUST met up with us to see us work and learn about our stoves. Next we built a stove for the queen mother of Patriensa. She was very thankful for the stove and remarked that she thought all the women in Patriensa could benefit from our stove. We worked until dark to build a total of 6 stoves that day. By the end of our trip we built a total of 37 stoves, a number we are very happy with. We could have easily kept going if we had more time. We had to turn down opportunities to build more stoves due to our trip ending, but we are hopeful that DeGraft will continue our efforts. As it was getting dark, we decided to visit three homes we had built stoves for the day before, and all three homes were using our stoves as we came by. This was such an encouraging note to end on. Mike was interested in following up on our project as well and told us that he intends to send one of his students to Patriensa to also follow up with our stoves and get feedback. Mike's student will be writing his thesis on biomass fuels and may include feedback from our project in his report. It is great to know that even though we are leaving, we have created points of contact to check up on our project.

Ending on a high note

We have continued to visit homes and build stoves over the past few days. We have built over 20 stoves total now, and we always have someone on the waiting list for another stove. Yesterday we explained to a woman why we seal the cracks between bricks in the stove with clay; to increase stability and to retain heat. When we visited her later in the day she had not only sealed all of the cracks in her stove with clay, but covered the entire stove in clay. This resulted in an sturdy stove with a very attractive look. We were all really impressed with the way her stove looked, and asked her if she would help us create a stove like hers for our public demonstration. Last week, we arranged for Nana Kontihene to set up an announcement over the village loud speakers advertising a sawdust stove demonstration. That demonstration happened to day, and we were all very pleased with the results.

We built two stoves for the demonstration, one from cement cinder blocks, and one from clay bricks coated with additional clay/mud. At 4 PM this afternoon, we lit the stoves and cooked a pot of rice to show how our stoves perform. Dark clouds and a light drizzle threatened to stop our demo, but thankfully, the rain held off for the time being. There were probably 30 villagers who showed up in addition to an abundance of kids. After the demonstration, we interviewed several people to get feedback on our stoves. We received only enthusiastic comments and positive remarks from those watching, and several people requested that we come to their homes to help them build one. Several people commented that it is easier for them to collect sawdust than to collect firewood because the sawmill is much closer to their home than the areas, which are available for gathering firewood. People liked how quickly our stove heated up the pot and noticed that our sawdust stove produced less smoke than their traditional three stone fire using firewood.

Today is our last day in Patriensa before leaving on a cultural excursion for Cape Coast. It was great to end on a high note with our demonstration. We have been working hard for the past 2 weeks, and are ready for a little relaxation time. We will be spending 2 nights at Cape Coast, and one night in Accra before returning to Patriensa for our final week on the project.

Moving Forward

It has been a few days since my last post, so I will fill you in as best as I can. The last few days have been very productive and encouraging. After seeing Gladdus’s stove, one of Gladdus’s neighbors requested that we build her a stove. We asked the neighbor if she had bricks we could use, and she assured us that she would have them in the morning. So on Friday morning our team met with Gladdus’s neighbor to help her set up a stove. When we arrived, a group of enthusiastic kids helped us gather clay bricks from some nearby rubble. A large pile of rubble, seemingly the ruins of an old home, contained a large amount of usable clay bricks. This was a very fortuitous pile of bricks that provided the means to construct four additional cookstoves at other homes. Because the bricks from the rubble were damaged, we wanted a method to fill the holes in the stove. This had also been the case with Gladdus’s stove, and Pastor Kofi had shown us how clay and mud can be kneaded with water into a useful consistency that will dry and seal any cracks or holes. We began to show the kids that we wanted to use mud to fill the holes in the clay stove, and immediately they caught on and took control of making it happen. While several kids were digging up dirt, mixing it with water, and kneading it with their hands, several other kids would grab the mud and patch the holes in the stove. Without any hesitation or instruction, the kids began to add palm fiber residue into the mud mixture to reinforce the mud and give it strength when it dries. This was something we had not even thought of, but we quickly adopted. This is exactly the type of organic progression we are looking for, we want to see the community take the design and make it their own.

More neighbors quickly began to notice the stove and all of the kids gathered a round it. Soon we noticed a pile of bricks forming in another neighbor’s yard with a request to help them build a stove. The kids helped us stack the bricks to form the stove while other kids produced and patched clay to fill in the holes. Before finishing the second stove, we already had a request to build a third. It was like clockwork. And the group of kids followed us to each home helping us with the mud for patching holes. By the time we had finished the third stove, we were ready to take a break for lunch.

Following lunch, we set off with our translator to find someone that knew how to make bricks. Though many people do seem to already have access to bricks, there are also homes that do not. Everyone we asked seemed to think it was easy for anyone to make clay bricks, but it was difficult to finally get a hold of someone who was able to do it for us. We walked for some distance through plantain farms and over some hills, asking directions to a brick maker from those that we met in our path. After finding his home and following his children to the place where he worked, we were able to arrange for 100 clay bricks to be produced over the next week at a reasonable price. The bricks will take two days to make and several days after to dry. We expect them to be ready by the end of the week. It is important that by the time we leave Patriensa, we have ensured that there is a way for those without bricks to either create their own bricks or purchase them for a reasonable price.

That afternoon we were scheduled to meet the village leaders at the palace for our official welcome ceremony. The term palace is a very generous term for the building we entered. The palace was a humble cement structure that contained an open-aired room with seats covered in cow hide lining the walls. The front of the room was raised one step higher and on it sat three chairs: one for the chief, queen mother, and kontihene (sub-chief). It was so remarkable to see all of the community leaders arrive in the traditional colorful garments. The chief was out of town so only the kontihene and the queen mother took their places at the front of the room. In addition to those at the front of the room, one clan leader from each of the 8 clans of Patriensa and the man appointed as a spokesman to the people of Patriensa attended the ceremony. The clan leaders sat on the sides of the room while we, the guests, sat towards the back of the room. Each of community leaders circled the room greeting all of us with handshakes before taking their designated seats. The ceremony started with a prayer, which was led by our technical advisor, Dr. Ezekoye, upon the request of the community leaders. After the prayer, we began by going around the room and introducing ourselves. The community leaders introduced themselves with their full names, including the name which represents the day of the week they were born on. I received a chorus of rooting and joyful laughter from the leaders when I introduced myself as Kwaku Clint, using my Ghanaian name.

After introductions, one of the clan leaders rose and explained that it is customary for visitors to state their purpose of being in Patriensa to the community leaders in order to be officially welcomed. The project managers for both teams where requested to stand before the room and state their project missions. I explained that our team was visiting Patriensa to help the community by using recycled waste sawdust to provide a free alternative cooking fuel, and Kristina explained how her team was in Patriensa to start a water sachet business in Patriensa that would provide locally produced clean water sachets to the community. After explaining our missions, the leaders officially welcomed us to Patriensa and expressed their support. It hit me how important it is for these communities to exercise their traditional ceremonies such as this in order not to lose them. I can’t imagine there are very many visitors to Patriensa who get to experience this ceremony, and I feel so fortunate to have taken part in this cultural experience. Before leaving, Kristina and I offered gifts to the kontihene and queen mother as is customary in their culture. My team wanted to bring gifts representing the state of Texas so we gave them each a UT mug, barbeque sauce, salsa, and assorted peanuts.

On Saturday morning we met with a roadside vendor selling cooked foods who requested that we build her a couple of sawdust stoves. Kids were eager to help us again and carried blocks from the pile of rubble to the vendor’s home by balancing them on their heads. People in Ghana carry anything and everything balanced on a cloth that is wrapped around their heads, from firewood to a bucket of yams. After building two stoves, she requested yet another one. As you might guess, she too had several neighbors that wanted a stove of their own. It has become necessary to start keeping a list of the people we have committed to build a stove in order to keep track of all the requests. Saturday afternoon, we spent some time sourcing more bricks and built one more stove at someone’s home. After dinner we met with Pastor Kofi, the kontihene, and two other PPE board members to discuss our the progress of our project so far and the things we need to accomplish before leaving.

Today, Sunday, we left in the morning on a one hour drive for Kumasi to visit a researcher at KNUST University named Mike. Mike, who both teaches and researches, specializes in applied research using ceramics. He researches ways to use ceramics to purify water, produce bricks, build stoves, and much more. He is also heavily involved in research to utilize biomass and agro-waste, such as sawdust, as fuel. We spent the morning discussing our project with him and learning more about his research. It was really valuable to connect with a local researcher, and I hope that our universities can collaborate together in the future. We learned a lot from speaking with Mike and there were a lot of interesting discussions that happened during our time together, but I won’t go into that now. Our team left KNUST in the afternoon and returned to Patriensa.

Before dinner we took the time to revisit a woman whom we had provided a cookstove for days earlier. We had left her some sawdust in our previous visit so we asked the woman if she had been cooking with the stove. She responded that she had been and that it had been working well. We were delighted to hear that, but not as delighted as we were when we found out that she had walked to the closest sawmill, bagged sawdust, and brought it back to her home to cook more! Up to this point, we have been bringing sawdust to the homes that we visit to encourage people to try the stoves out. This woman had used up the sawdust we originally left her and gone to get more on her own. It was so encouraging to see that she had seen the value in our idea and the money and/or time she could save with it. She explained to us that our stove can cook meals much faster than her other stoves can. We all left her home with lifted spirits as we headed to dinner for the evening.

Eating for a greater purpose

Mehoye! (Hi, how are you?) This is a common Twi phrase used to greet one another. Today was full of surprises, both good and bad. After spending several days in the community, we thought it would be great if the local schools adopted the sawdust stoves and used them to serve hot meals to students. We helped several school cooks prepare meals for students, but noticed that they did not seem as excited as individuals cooking in homes that we visited. We seem to always get positive feedback, but it can be hard to tell whether they are truly interested or just being polite. The cooks we work with know very little English, so we are able to communicate best when we have a translator. We can often gauge their level of interest by their tones and actions. We were disappointed that the primary school cook did not seem to be very engaged in the new idea, but we were able to help her cook a very large pot of jollof rice for the student lunches.

In the late afternoon, we headed back to visit the elderly lady named Gladdus who requested the first sawdust stove, to see how she was doing. When we arrived at her home, there was already a pot of food boiling away on the sawdust stove we built for her. Our spirits were lifted as we spoke to her about her about her experiences cooking with it. She was already developing her own methods for using the stove from the way that we originally shown her to tailor to her needs. This is exactly what we have been waiting for, individuals that see value in the stove and make it their own.

After leaving Gladdus’s, a translator accompanied us to other homes in Patriensa to tell people about our stove and ask if they would be interested in trying it out. As we talked to each household, we received an overwhelming response of interest and enthusiasm to try our cookstove. Everyone asked us to come to their homes and build them a sawdust cookstove. Why were we receiving such excitement from the individual homes but not from the schools? As I thought about each scenario, I developed a theory. The school cooks are likely not paying for their cooking fuel because they are employees of the school. Because of this, they are not benefiting directly from the money saved through a free cooking fuel. The individuals and street vendors immediately appreciate that they can save time or money by using sawdust as their cooking fuel. After spending so much time helping school cooks, it was encouraging to end the day with so much interest and positive feedback from community members.

Although we didn’t feel as successful at the schools with our cooking product, it was a lot of fun being around all of the school children during recess. All of the kids want to feel my skin, almost as if to see if my color will rub off. At times there are several kids on each hand, and some will rub on my legs. I have also experienced kids trying to scratch it off, which is much less pleasant. We played some soccer with the kids as well as simon-says type of game. I say simon-says, but the kids naturally wanted to do anything we showed them, from jumping up and down to hook’em horns. We ended our day with a meal of white rice, chicken, a tomato sauce, and fried plantains. More members from our program in the US also arrived today to join us in Patriensa. Tomorrow is a Ghanaian holiday so we will have a slightly more relaxed schedule. Tomorrow afternoon we will formally meet the Queen Mother of Patriensa who will officially welcome us into the community.

Because we are helping people cook several times a day in addition to eating lunch and dinner each day at the secondary school, we often find ourselves in sticky situations. After helping people cook a meal, they typically insist that we eat some of the food they have prepared. This wouldn't be a problem except that they often give quite generous servings...and we do this multiple times a day. I consider myself to be pretty good at scraping a plate clean, but even I have been struggling with the amounts of food. It has been a struggle to finish all of the food they provide, but we push through as best we can. It can be even more difficult if we are not particularly fond of the food being served. They typically provide one or two dishes and our whole team eats off of them with our hands. In these times, we dig deep and tell ourselves we are eating for a greater purpose.

Arrival in Patriensa

I have not had internet access since leaving the city, but we were able to purchase an internet bundle today for our modem. Today was our fourth day in the village we are working in called Patriensa, and a lot has happened. Upon arriving in Patriensa, we were greeted by Pastor Kofi, the community pastor. Pastor Kofi welcomed us, and gave us a quick tour of the places and sites that we would be working at in our projects. Our sleeping arrangements in a local guesthouse fell through, and we realized that there was a miscommunication in the dates that our local contacts provided to the guesthouse on our behalf. So we are currently staying at a hotel in a nearby town called Konongo. Each day we drive to Patriensa in large vans used for public transportation all over Ghana called tro-tros. A tro is the old word used for coin, so the name tro-tro came about because it costs one tro to get somewhere and one tro come back back. There is a local secondary school that serves hot meals to students, and that is where we eat our meals for lunch and dinner. We learn a lot of useful Twi (the local language, pronounced chwee) phrases from the students at the school.

Before I go any further, I want to talk about the actual reason that I am here in Ghana. There are two UT projects going on this summer in Patriensa, the sawdust initiative (my project), and the water sachet project. Both of these projects are associated with a non-profit organization called Patriensa Pure Enterprises (PPE). PPE was jointly established through a partnership between the University of Texas, KNUST (a local university), and the village of Patriensa. The PPE board of directors consists of people with vested interest in the community, including members such as Pastor Kofi and the Kontihene (term for the village sub-chief). PPE oversees projects that support the community, and uses any generated profits towards other community initiatives that can benefit the village. PPE helps to provide a framework and management system for the projects we are working on.

My team is working to convert waste sawdust produced from lumber mills into an alternative cooking fuel. The timber industry is very large in Ghana, and large amounts of sawdust generated from cutting wood are simply burned off as waste in order to make room for the next collection of sawdust. Sawdust on its own burns unreliably, so our mission is to create stoves that burn sawdust efficiently. We have developed stoves that can be made from cement or ceramic bricks, which are universally available materials. These stoves are able to boil 2.5 liters of (standard boiling test) water in under 10 minutes. Based on community feedback, using firewood takes on the order of 20 minutes to boil water and charcoal takes about 30 minutes to boil water. Charcoal is great for cooking because it is smokeless, but it can cost a substantial portion of a person’s income if bought regularly. Firewood is great because it is free but it takes anywhere from 2-4 hours a day to collect. The time to collect firewood can only get worse as they continue to chop down trees leading to deforestation. The ideal cooking fuel in these rural areas, liquefied petroleum gas (LPG), is only used by the wealthiest top 5%. Sawdust provides a unique opportunity to create an alternative free cooking fuel that is capable of quickly achieving high temperatures.

We spent the first day testing our stove design in Ghana, and sourcing local materials such as bricks and bamboo. The last few days we have spent visiting homes and schools around the village. We have spent the past couple days visiting cooks in their homes or at a school, and asking them if they would be interested in cooking with a sawdust stove. Then we offer to build them one and help them use it to cook a meal. We ask them questions about their current stove and cooking fuel as well as ask them about their impression of the sawdust stove while they are cooking. We bring food to the homes such as yams or rice to help with the meal they cook with us. It has been really exciting to see some of the feedback we are getting. They are always impressed with the sawdust stove’s ability to quickly boil water, and they tell us that people will be eager to use a stove like these if the fuel is free. One elderly woman demanded that she be the first one to receive one of our stoves. When we showed the woman how it worked, her daughter told us that she planned to get bricks and build one for herself. The elderly woman also told us that one of her relatives worked at a lumber mill near by and could probably deliver sawdust to her house. It was really encouraging to see their excitement.

Each stove has been a little different because we try to use materials that are readily available to each person. There are piles of bricks littering the entire village and the roadsides all along these rural areas. People don’t take out loans here, so when they hope to improve their home, they will purchase small portions of bricks and materials over time as they are able. It seems as though they buy the bricks very optimistically because many of the bricks are growing moss and eroding to the point where they would no longer be structurally sound. They hold on to these bricks as dreams for a better home, though I think many people never get around to using them. The bricks may provide an opportunity for people willing to spare 6 or more of them to use them to build sawdust stoves. Some bricks are clay while others are made of cement, and they come in different sizes and conditions. So we have created a variety of stoves based on the materials available to each cook. We are also willing to provide bricks for cooks that do not have access to bricks, but it is better when we can see that it is easy for community members to get their own materials at little or no cost themselves. One option we are exploring is for villagers to gather their own clay and to create their own stoves. Nana (term of respect) Kontihene showed us where to find clay a short distance away from the village, and we gathered a little clay from the ground using a machete ourselves. We are told that anyone can gather clay for free and that everyone knows how to use it though it is a lot of work. This was another encouraging realization because it means that people are able build their stoves for free and gather sawdust for free. The clay was in a forested area with many cocoa trees, another large industry in Ghana. Nana Kontihene grabbed some of the cocoa from the trees, cut it open, and gave us cocoa pods that can be sucked on. It tasted nothing like chocolate, but after that we sometimes refer to the area as the chocolate rainforest and the name stuck.

I have been given a couple new names since arriving in Ghana. Each Ghanaian is given a name based on the day of the week they are born and their gender. Being born on a Wednesday, my name is Kwaku Clint. Pastor Kofi received his name because he was born on a Friday. They have several other names in addition to their name based on the day they were born. My other, and much more popular, name is obruni, or white man. As we walk through Patriensa we are followed, and at times surrounded, by energetic and laughing children shouting obruni.

It has been a truly unique experience to be here in rural Ghana. There is so much to take in and I am learning more everyday about the life and culture of the people here in Patriensa. The other day, Pastor Kofi spoke to me about how their extended family system works in Patriensa. The way he explained it stuck with me, “Everyone belongs to a family, every family belongs to a community, and every community belongs to a society.” So everyone has a duty to serve his or her family, community, and society. Though it is unlike anywhere I have ever been, being here reminds me of the times I spent in the Napu village in Indonesia growing up. I have so much more to write about, but I will end here for now. The days have been full and I am pretty tired by the time we drive back up the bumpy dirt road to our hotel in Konongo, but I will try to get my next post up sooner now that we have access to internet.

Setting Foot in Africa!

We left Austin, TX yesterday afternoon and arrived safely in Accra, Ghana this evening around 8:30 PM after connecting fights in Chicago and London. Our team was met by a travel agency here in Ghana called HLG at the airport who took us to our hotel. There are 5 traveling members of the team, 3 engineers and 2 social work students, as well as a UT professor who serves as our technical advisor. Our whole team was reunited for the first time at the hotel, and we shared our first Ghanaian meal together. I ate tilapia and banku, a bland starchy ball of dough commonly found in West Africa. I think I'm going to become pretty familiar with banku and similar starchy dishes in the coming weeks. Aside from some aggressive baggage carriers at the airport looking for a tip, everyone has been warm and friendly. It's pretty late here and I need to get up early to drive North to Kumasi, so I will keep this post brief. I do not know yet what to anticipate for internet access over the next 4 weeks, but I will do my best to keep the blog updated. Its been a good start, and I am really excited to experience Africa over the coming weeks!

Ghana Briquette 2012

Hi everyone!

Greetings from the 2011 - 2012 Ghana Briquette team. We are excited to pick up the baton from last year's team and move forward. This year's team, consisting of four engineers and two social work students, is building upon the success of the 2010 - 2011 Ghana Briquette team and working to further lay the foundations for a briquette enterprise in in Patriensa. 

For those of you who are unfamiliar with this project, we are working to start a social enterprise that will produce and sell briquettes made from recycled waste sawdust. According to local contacts, families in the village of Patriensa, Ghana, spend two to four hours daily, traveling six miles out of town by foot, to gather wood. Alternatively, charcoal is an unsustainable and expensive fuel source produced by cutting down large trees and slowly burning them over the course of several days, further contributing to deforestation. In addition, purchasing charcoal heavily taxes the personal income of villagers and sends local money to outside entities. The sawdust produced by the lumber industry in Patriensa provides a unique opportunity for the production of a sustainable alternative fuel source by recycling the waste sawdust through a process known as “briquetting.” Simply put, briquetting compacts biomass using pressure generated by a hand press in order to produce a fuel that can easily be used in place of charcoal or wood. The biomass mixture consists of sawdust and a binder, which may be comprised of a range of local materials such as manure, palm oil, and casava.

The establishment of a local and self-sustainable social enterprise around briquetting will offer the residents a more affordable source of energy for their meals as well as job opportunities. The enterprise will sell briquettes produced by employed community members. A board of directors that has vested interest in the community will oversee the enterprise. All profits made from this business will go towards a fund managed by the directors set up to finance future community projects and improvements. Our team will fully develop and test the briquette press, determine the optimal briquette mixture, and construct an efficient solar dryer for drying the briquettes. Fuel mixtures will be tested to decide which mixture will prove most effective for our market. We plan on educating the community about the process of producing a briquette and the sustainable properties it holds.  Several enterprise strategies will be researched to discover the most effective way to ensure the success of implementing briquettes in the community of Patriensa.

Stay tuned, more posts to follow!

Wrappin' up

The project has officially come to a close, and the team was sad to say our goodbyes to the warm-hearted community of Patriensa. Luckily, my schedule was flexible enough to allow me to push back my departure date and continue my involvement with Patriensa and the project for a few more days, as well as help a social work student, Tim from the PUC Sachet Team, conduct valuable research in assessing the community’s needs through dialogue with leadership and community members. I look forward to learning more about the social work world and how engineering fits within the community development framework.

As far as the progress of the PUC briquette team before the official ending date, we were able to complete all of the objectives that we set your to accomplish, and feel that the contribution that our team made to the two-year briquette project was immense.  Along with meeting our goals, we were able to create a surplus of preliminary briquettes for testing. Around fifty or so were sent back to Texas for testing in the controlled environment of the lab. About another 150 were left here in Patriensa. Our hope, if approved by the management team back in Texas, is to conduct burn demonstrations here in Patriensa and gain feedback from community members on burn characteristics during my extended stay.

I would like to thank the whole team, not just those lucky enough to travel, for the hard work and dedication to the project. Also, our project advisors Marty Rumbaugh, Dr. Kristin Wood, and Dr. Christina White were invaluable assets during our work, offering patient guidance and knowledgeable advice throughout our time here. And of course our success greatly depended on the involvement and support of our friends and acquaintances here in Patreinsa and Kumasi, and we are all fortunate to have the pleasure of knowing such generous and kind people. Patriensa will be greatly missed, but perhaps a team member or two could pay a return visit sometime….

Until updates of the continued work come in, here are a few photos of the work we did and the friends we met:

Until next time,

It's been too long!

Sorry for the delay. Who would have thought? Reliable internet is hard to find in rural Ghana!

There have been a slew of updates since our last post. After the broken press, we arrived the next morning to find that the manager of the saw mill donated new lumber to the project. Due to his generosity, we were able to fix the press in no time. Following the repair, we made about 20 different mixtures of briquettes, conducted burn tests, and produced more of the briquettes that burned well. Production with the press is in full swing, and we are looking forward to more samples for testing.

We have made some great progress on the community involvement front. After working during the morning producing briquettes, we headed home for lunch. Upon arriving back at the press, two of the sawmill workers were eager to show us the briquettes that they had developed.

We were fortunate to be able to visit the Kwame Nukramah University of Science and Technology. There we met with three very helpful academics, all with experience in briquetting biomass and one who specializes in rural community enterprise. We learned a lot from our meetings and are excited about future collaboration on this project and others.

Friday is our last day in Patriensa, and nobody is looking forward to leaving. We have accomplished much in our short time, and are feverishly working now to make the most of our remaining time. We will update you after project completion, goodbye for now.

Life has its ups and downs

So we’ve got good news. The press is built! Unfortunately, we also have some bad news. The press is broke.

The saw mill that we are stationed has been a great work sight. We have shade, solid ground to work on, and the most friendly and curious workers that anyone can ask for. The kindness that Ghanaians exude has been nearly overwhelming. The workers at the mill, having only casually met us during our work, insist on helping us carry our tools and supplies across the lumber yard every morning and afternoon. The owner offered, without our asking, to lock the tools in his office nightly.

The press construction went slower than expected. Unfortunately the electric tools that we brought don’t like 50 Htz electricity available in Ghana. Therefore, some manual labor was in order. It took longer than hoped to source a hand drill and wood saw, but we finally succeeded. When the tools were available, press construction moved along as planned. We finally completed the press yesterday. It was looking good, so we decided to press a few briquettes before dusk. During the second compaction of the first batch of briquettes, we heard a loud crack. Immediately, we noticed the cracked main beam that compresses the briquettes. As bad as it looked, we decided to continue to carefully work until it reached complete failure, thinking that a patch would be impractical, so complete replacement was inevitable at some point. The third and final compaction was the last it could take. The two hardwood 2x6’s broke with quite a startle. It appears that the wood that was used to create the main beam was old and rotted, with evidence of mold growing along the fracture line. We hung our heads and called it a day, planning on purchasing new wood first thing in the morning. On the way out, we mentioned the problem to the saw mill proprietor. For the loss, he agreed to purchase outright the replacement boards for the beam. On the bright side, he happened to be cutting 4x6’s for a client, a perfect replacement to our joined 2x6 set up. We agreed to the deal and will start work tomorrow morning.

Another point of mention is that we designed and built the drying rack. It is an A-frame structure supporting bamboo pieces acting as skewers for the donut-shaped briquettes. We have had a lot of luck finding wild bamboo locally, and are anxious to get it working. That’s all for now, updates to follow.

Day of rest

Sunday was used as a recoup and relaxation day. We all attended Sunday church service at Pastor Kofi’s Presbyterian Church in the center of Patriensa. It was a welcome rest day and culturally awakening. After church service, several of us played soccer with the local children who were out of school. Overall Sunday was well received by the teams and left us ready to work hard on Monday.

Hard at Work

Double post today! Our work these past few days has kept us too busy to make it to the local internet spot but we are making it up now. We've had a lot of progress. After a day in Kumasi gathering materials and meeting with some local contacts, we made it back out to Patriensa in time to have a quick team meeting before crashing in bed. Rising at sunset has been a hard transition! Today was incredibly productive. We started the day with a meeting with the local sawmill owner, who granted us permission to use the facility to work. We set to work early, where we were joined by several interested men that were on the grounds. After some curious watching from afar, we shook some hands and had some very helpful volunteers swinging hammers with us. It has been incredible how many people have been willing to lend a complete stranger a hand, no matter how strange the task. This continues to remind us how friendly and open Ghana is, and for that we are very thankful. The work continues tomorrow, with lent community tools and welcoming greetings. Updates in a few days!

Arrival in Patriensa!

After an early start this morning, the team headed to the village Patriensa from Accra. Upon arrival, we were greeted at the guest housing accommodations by Pastor Kofi, community leader and pastor of the local church, along with the kontihene, the right-hand man to the Chief. Our first view of the village started with a tour of the future site of Patriensa Pure, PUC Ghana Sachet team future facility for the production of sachet water and the repurposing of sachet bags. We also toured both sawmills in town, where we were pleasantly surprised with quantity and quality of sawdust and tools available.

The most interesting part of the day came upon meeting the Chief of the Patriensa area. At the chief’s palace, we were greeted by an assortment of sub-chiefs in colorful Ghanaian clothing. We were very warmly welcomed, and sat in on the traditional council meeting. Fruitlessly, we tried to catch bits and pieces of the local dialect, but to no avail. Pastor Kofi, fortunately, was there to translate for the team. After formally presenting our project to the Chief through Pastor Kofi and the Linguist, we said our goodbyes to the incredibly friendly Chief, and made our way back home. Full of freshly cooked rice and chicken, we began our night’s group meeting. Overall, a very promising day for the success of the project and a renewed zeal to begin work early in the moring.

Welcome to Accra

All of the team members arrived in Ghana yesterday with no issues. The flights were long and there wasn’t much sleep had, but fortunately we had a comfortable hotel room waiting. Today we toured Accra with our very kind and helpful guide Kwame. We toured the Kwame Nkrumah museum, where the following picture was taken, and visited the sprawling market at the National Cultural Center. After lunch on the beach we visited Trashy Bags with the PUC Ghana Sachet team. We set off early tomorrow morning for Patriensa, ready to make some progress!

Ready to go!

We've been working hard preparing for our departure tomorrow. Sam, Alex Kykta and I will be travelling with the Ghana Sachet team, while Marc and Simon will provide support from home base. We have some very knowledgeable technical advisors travelling with us and are anxious to finally meet all of our local Ghanaian partners. Everything is packed and ready to go. On the ground in Ghana in two days and can't wait!

Redesign in Progress

The SLAB meeting went really well! We receive some very positive feedback and some great suggestions for our future plans. Furthermore, our project has been officially approved by UT's International Office. So now we're rolling out travel plans as we work on our project.

Concerning our project, Alex B. and Sam are working on testing briquettes and analyzing their burn characteristics, while Alex K., Simon and Marc are beginning to work on the press redesign. We are very happy with the press we've built, but we want to make sure only the best design will be implemented in Ghana!

Here's a video showing how our press churns out briquettes:

We also plan on making numerous drafts using SolidWorks CAD software and printing out more 3D models before we built our improvements. Here's an example:

Using SolidWorks, we can visualize any changes we make, along with motional and stress analyses. We're very excited to see what we come up with, and we'll have more updates later.

More Briquettes, More Experience

Today is our Service Learning Advisory Board presentation regarding our final approval for travel.  If all goes as planned, we will be green-lighted for travel by the day's end!

We've been pumping out a lot of briquettes lately.  We've learned a great deal about the production process, and have made several refinements to our equipment.  A baseline production rate was established at about one briquette per minute, and after a few process refinements, we were able to increase this rate by ten percent after working on it for only one day!  We look forward to continuous process improvement and refining our equipment for improved briquette production.

For a future outlook, we are looking towards carbonizing the briquettes. There is one prototype in the picture above, though many more will need to be produced for any kind of relevant results.  Shatter tests have been performed on some controlled parameter briquettes, and we are sorting through the data now.  Soon we will be conducting some combustion analysis tests, monitoring burn time and peak heat output.  More updates to follow soon!

Press built, molds built, briquettes!

The press has been refined a bit, several mold designs built, and a few preliminary briquettes have been pressed.  Overall, it's been a busy and successful week.  Below you can see two molds and accompanying plungers.  

Here are some briquettes laid out to dry.  We experimented with a few parameters just to get to a reasonable size, shape, and consistency.  We have a more rigorous experimental procedure developed, but were too excited to have the molds done not to produce a few.

While we were on a roll, we couldn't resist burning some.  Two days in the sun left these briquettes were plenty dry to burn.  The lit easily with newspaper and burned really well.  The densest ones flamed for a bit, then glowed red-hot for a while, very similar to charcoal.  Promising results!

Briquette Press Built

The press is built!  Sam and I (Breckel) did the final assembly today, and it looks great!  Just a little bit of final polishing up to do and we can start producing briquettes with it.  

And it only took one extra trip to the hardware store. Lots of lessons learned during the prototyping, it's been a great experience.
