The Dar es Salaam Example
Typical family in Dar es Salaam • In DSM organic matter accounts for around 67% of the
total amount of municipal solid waste generated
• Much of this waste is disposed off on the streets or in
• Daily consumption of charcoal for a family of open dumps
five persons is around 2.8 kg • This leads to pollution of ground- and surface
• With a price of around TZS 35,000 per bag water, the breeding of insects, and the spread of

19. Consortium of parties bring Simgas Biogas to
5,000 farmers in Tanga
The Tanga Example
Consortium of parties teamed up to bring Main reasoning for parties to engage
Simgas Biogas to 5,000 farmers
1. Increased health of farmers (women)
leads to higher productivity
2. Improved income position
3. Improved income position leads to re-
investment in more cows
4. Improved manure leads to better
feeding of the cows and increased milk
production
Contributions of parties
TDCU: Engages all member Sacco’s and provide
for instalment collection administration
Farm Friends: Provide for the necessary
collateral
Tanga Fresh: instalment collection through milk
payments and financial support

20. Farmers and Families in Urban and Rural areas
should have a Simgas Biogas Digester
Take Away
Biogas is a technology to convert biodegradable materials (like manure, kitchen waste, waste
from crop processing, sewage) to gas. This is done from small scale families to large sewage
treatment plants. The gas is used for cooking, lighting, electrification, cooling, and other uses.
1. Simgas can provide BIOGAS for sustainable (cooking) energy to 200,000-500,000 farmers in
Tanzania, saving them $300-$450 per year, increase their earning capacity, and improving their
health. The slurry will increase the crop output, strengthen soil fertility, and increase income.
2. Clean BIOGAS can also be provided for families without livestock or waste from crops using only
biodegradable waste from their kitchen. This will displace charcoal use and therefore limit
deforestation in the rural areas.
3. Biodegradable waste from (cash)crops can also be converted to energy (from
wheat, barley, coffee, maize, jatropha, avocado, tobacco etc.).
4. Other opportunities should be providing Biogas to Pig farms (obligatory?), Fish
farms, incubation, vermiculture, and seed storage.
5. Larger scale farmers and institutions can even use their Biogas for micro-grid electrification.
Biogas is the premier Climate Mitigation tool if expanding sustainable agricultural productivity. 20
