Build a Biogas Plant


Biogas Kits

Biogas kits can save you constructing a plant from scratch and are generally researched and designed for your particular area ensuring you get optimal performance. Although we have used the term 'kits' which are domestic units, some of the systems below are medium to large scale. Don't forget to checkout our School experiment kits, lessons and downloads which can be found on our School Biogas Kits page.



Biogas KitBiogas Australia can supply DIY kits for Hobby Farmers and householders who want to make use of their household waste to produce biogas for cooking, lighting or hot water as weel as electricity generation.

Arjun BiogasArjun Energy Coporation operate from a base in Tamil Nadu, India. Established in 1994, the company manufactures and supplies a wide range of biogas plants to the domestic as well as the industrial sectors. The picture shows a 1m3 capacity digester for domestic use in rural areas. The company is trialling a small portable 'Air Pillow' unit which uses poultry droppings as feedstock.

Boitech biogas unit IndiaBiotech have offices in Thiruvananthapuram, Kozhikkodu and Ernakulam. In these small domestic biogas units, kitchen waste material mixed with wastewater is fed into the plant through the inlet chamber at the top. The space required for a domestic plant (1 Cm3) is one square metre. Installation time suggested is about 1- 4 hours, depending upon the model of the plant and the location. The gas generated from the waste of a family of 3 -5 members is sufficient enough to work a single burner stove for more than 2 hrs everyday.
The return on investment (ROI) of a domestic  bio energy unit is quite good. A 1 Cm3 plant can save 70% - 90% on the consumption of fire wood or other cooking fuels each day. Within 2 years the entire investment can be recouped by the production of cooking (gobar) gas and liquid fertilizer.
