It’s hard to believe it has been about two weeks since we packed up and rushed to catch our respective planes to Los Angeles, San Francisco, Nairobi, Auckland and Mumbai. We had a whirlwind last few weeks switching our focus from making visits to groups, villages and communities associated with the Jane Goodall Institute to a more centered approach heavy on the resource development and final testing of briquettes before we headed home.  Resource development consisted of our hours on hours of office work dedicated to creating a full-length documentary film on DHE and bioenergy in Tanzania (thank you, Olivia!), a mini-series of videos on different technical aspects of briquetting (Dvij and Jun will be finishing these up back at Dartmouth), a full length report on our work over the past few months (my own project), and finishing up tons of translations, photo selections, report edits, impact and economic analysis additions and more (Steffi is a goddess). We also made the obligatory visit to Gombe National Park, where Jane Goodall did much of her landmark research on chimpanzees.

The team finally makes it out to Jane Goodall’s breathtaking peak at the Gombe National Park.

For final testing, we did a lot of number crunching to see what the profit margin would be for our partners’ briquetting operations – each of a different group size, with feedstocks and biomass of different costs and with kilns of different sizes. Each organization can, in fact, make a profit from briquetting! We also collected information on the quality of the briquettes – they effectively cook water, porridge, beans and more! This info was invaluable, in our opinion, because we got so many questions on exactly these points of concern and because we could send the info to our partners and give them more data on the financial and technical viability. Others interested in briquetting might reference this information and use our tested ratios of binder (the sticky porridge) to filler (the char) along with our manuals and more to make their own briquettes.

It has been incredible to experience the applied value of briquetting, engage with communities and groups interested in learning more about bioenergy and see what might come next. While DHE does not currently have any plans to send more students to Tanzania, the project is ongoing. Last week I was so excited to present to a local Rotary club in Los Angeles about the experience and what bioenergy in Tanzania was succeeding in and what still needs work. We will continue to stay in touch with partners and continue to adapt and take bioenergy in the direction of the needs of different partner groups, communities and organizations at Dartmouth and beyond. Thank you to everyone who supported our team for what I will always remember as a remarkably special experience. A few thing’s are certain – my Swahili book is still getting a good amount of use and my Facebook is active with communication with those with whom I spent so much time. Asante tena kwa kila kitu! Until next time…

Hujambo from Arusha!

The 14X Bioenergy Project team has arrived to Tanzania! We got to the bustling city of Arusha in northern Tanzania only three short days ago. We were very warmly welcomed and picked up at Kilimanjaro Airport by Didas, the head of EMORG in Arusha. He took us to the volunteer house, where we are staying for the rest of our time here (approximately 4 weeks in Arusha). It is very homey place to come back to after a long day of working – complete with a TV to catch up on World Cup games, Dvij’s acoustic guitar, and two adorable little puppies. Betty has cooked so many delicious meals for us. The group favorite thus far has been “chapati”, a Tanzanian crêpe, and “pilau”, a deliciously tasty rice dish. We have been graciously accompanied around town by three incredible guides: Filbert, Jennifer, and Lalashi. We are so grateful to EMORG to have them with us to show us around and help us settle in.

We’ve only been here three days, and yet we have hit the ground running. We’ve been figuring out how to get from point A to point B in Arusha, learning Kiswahili, and setting up meetings with partner organizations. Through this blog we plan to give updates on the progress we make in our work over the course of our stay, provide some insight into the things we learn, and share some tidbits about our adventures and the people we meet.

Today, the team had its first meeting with EMORG in the Kisongo region of Arusha. EMORG is an NGO that supports the local community with a beautiful library space and school. EMORG also has a powerful women’s group that creates briquettes (wood or lump charcoal alternatives) and other goods for sale, with whom we will be working this June and July. We met the women’s group, and their leader Mama Nuru, and participated in a briquetting session with them.

We were able to see the exact process that the women’s group uses to produce briquettes. First, they collect small bits of charcoal fines from the market which they can get for free. They grind this in a contraption that somewhat resembles a big spice grinder. A wooden bowl is filled with the charcoal bits and then those bits are smashed into a powder by large wooden staff. This powder is then mixed with a binder. The binder that the women’s group uses is a porridge-like mixture of hot water and cassava flour. The black paste of charcoal powder and binder is then pressed into disk-shaped briquette molds using gear modeled by DHE. These are then laid out to dry on a tin sheet in the sun. Once they are dry (takes approximately 3 days), the briquettes are sold in the local Kisongo market at a price of 1 kilo (22 briquettes) for 1000 TSH shillings (about 60 US cents). The women estimate that they make about 18-20 kilos of briquettes per week.

The biggest issue facing the women’s group at present is that they are running out of charcoal chips to use. This comes down to two primary reasons. The first is that the government is beginning to restrict deforestation, meaning that less wood and thus less charcoal is being used nationally, meaning fewer fines available to collect at the market. The second is that due to recent, climate change-induced inclement weather many leftover chips have gotten wet in the markets or blown away. So the women are in need of a different briquette process. In times past, the women used the bottom-lit updraft (BLSD) kiln that the 13X team built. However rains and harsh weather have destroyed this kiln. The 14X team is now planning on building an educational, small-scale top-lit updraft (TLUD) to demonstrate for the women’s group, which has the advantage of being portable in case of harsh weather and also is able to take advantage of different feedstock sources – sawdust, corn husks, coffee husks, etc. The women’s group found that corn husks were not particularly effective, so we are planning to test the TLUD with sawdust which costs 2000 shillings per 100 kilos in the Arusha market and possibly kahawa or coffee husks.

Tonight we spoke to Didas about this plan, and he has helped us execute a strategy for finding materials and building an educational TLUD. He has machine equipment at his office in Arusha that we can use. If all goes well, we plan on building this TLUD by Thursday which is the next time that the women’s group meets. If it is not done in time, they also meet on Saturday.

So the plan until Thursday is to build the TLUD. Simultaneously, we also have plans to meet with previous partners from Vision 4 Youth and Lulu Vicoba. Stay tuned for more…

Baadaye (Until next time!)


Here’s a bit more about the team!
