- Biodiesel production station
Sustainable development and sustainable growth
Kasetsart University produced biodiesel by BTC-150 machine. The BTC-150 has a capacity of 150 liters/ time and develops consecutively to KUB-200 which has a capacity of 200 liters / time, with a capacity of 700 liters / day.

A 100-kw.- farm generator powered by integrated fuels of synthesized gas from a 3-stage and diesel oil gasifier powered by fuel of paddy husk and diesel oil compressed bar charcoal on process of production
Biogas production station
Biogas production station of Kasetsart University produced gas from food waste 400 kg. /day and converted into heat energy from a gas tank of 15 cubic meters to use in the canteen.
Dry broiler manure 4 tons/year Dry manure from 6,500 layer chicken yield 20 tons/year Utilization 12 tons of manure was put into grass plot. 8 tons of manure was put into biogas pit.
Poultry manure is put into biogas production dome. The biogas is used for electricity generating system of poultry farm. It is also transformed to fertilizer pellet.
.
7 tons of pig excrement are processed into 12,000 liters of liquid fertilizer for cultivation. It is used 1.5 liters per rai /crop for 8,000 rai of paddy field and 3.5 liters per 3,400 rai of cassava.
Swine manure is put into digester tunnel to produce biogas for in-farm cooking and herbal sauna.
.
Dairy cattle manure is put into digester tunnel to produce the biogas for in-farm cooking and pasteurized-milk production.
.
Cattle manure is put into covered digester pit to produce the biogas for farm electricity. It saves electricity cost of the farm.
- Producing hot gas with a Gasification Stove
Gasification Stove has a diagram of Figure 1, which is heated to the neck at about 1200 ° C. This hot gas is heated to about 5,000 kilojoules (kJ)., which can be ignited. The composition of the biomass consists of Carbon Monoxide 18-25%, Carbon Dioxide 5-10%, Hydrogen 13-15%, Methane 3-5%, Nitrogen 45-54%, and Steam 10-15%. There is also a hot gas fired furnace with charcoal and biomass as shown in Fig. 1 and Fig 2.
