For instance, the high unit cost of the VACVINA biogas digester
significantly contributes to the feedstock processing in Moshi while that of the plastic biogas digester
Responses in the environmental impact categories resulting from the combined flaring of biogas and reduction of the digestates being discharged would result in a significant reduction in the emission of greenhouse gases from the system with a household biogas digester
compared with traditional management.
Ann Lenhart, an American Fullbright exchange engineering student at the University of Namibia's Ongwediva campus developed a biogas digester
. The school is currently experiencing a shortage of fuel because of the scarcity of wood therefore the digester will help the school to implement its feeding programe by creating an alternative energy supply as opposed to using wood.

, anaerobic bacteria (bacteria that thrive in an oxygen-free environment) decompose organic matter into methane, carbon dioxide and sludge.
He said the Malagos Farm is a perfect example of sustainably managed farm since grass under the coconut and cacao are fed to the goats and cows, with their waste going to the biogas digester

Construct a small-scale biogas digester
: Using a 5-gallon bucket, organic matter such as plants, chicken manure and dead leaves can be turned into methane gas.
Our pupils have provided a biogas digester
that turns cow pats into electricity.
Entec Biogas GmbH of Austria provided the biogas digester
system to PEDA.
A biogas digester
consists of one or more airtight reservoirs into which a suitable feedstock--cow dung, human waste, abattoir waste--is placed, either in batches or by continuous feed.
