anglais. In a course of research there was studied a simple and inexpensive technology to produce biogas and bio-fertilizer using fresh cow-dung in combination with paunch content. As a result of realized research there was revealed that the generated biogas can be sufficient for a family of 2-4 people per day having 1-2 cattle, so this low-cost tubular plastic reactor was recommended to smallholder farmer due to its cheap cost of production (USD 80-100), and using local materials as well as ease of installation and operation. There are different kinds of biogas technologies for biomass processing which include biogas digester - ahermetically sealed container, where at a certain temperature an anaerobic digestion of prepared feedstock occurs and finally biogas are produced. Such techniques allow processing of any kinds of organic materials, such as listed above (both solid andliquid) into biogas. However, the most efficient use of biogas technologies for processing livestock and poultry farms wastes should be characterized by timely availability of the waste as well as ease of collection. The quality of raw material feed to the biogas plant is characterized by humidity, biogas yield per unit of dry matter and methane content. Feedstock humidity should be at least 60 - 85% for tropical condition and the yield of biogas depends on the type of feedstock used and the temperature during the fermentation.

Результат эксперимента показал, что полученного таким образом биогаза должно хватить на день семье из 2-4 человек с 1-2 коровами, так что этот недорогой пластиковый трубчатый реактор был рекомендован для мелких фермеров из-за дешевизны производства (USD 80-100) и использования местных материалов, а также простоты установки и эксплуатации.
