Technology of Biomass Waste Utilization for

Energy• Direct Combustion : fixed bed boiler, kiln boiler, fluidized bed boiler.A bubbling fluidized bed boiler is very suitable to be applied forcombusting materials with high moisture content like EFB (EmptyFruit Bunch) or biomass containing watery particle

• Gasification Technology :Biomass gasification is a thermo-chemical process by which solidbiomass (wood, rice husk, corn cob and the like), either in fresh or carbonized states (charcoal), is converted into amixture of gases that contain many or all of the following :CO, H2, methane, CO2, water and simple olefins.

Zero waste Agriculture for Green Energy

Zero waste Agriculture for Green Energy

Zero waste is“ philosophy that aims to guide people in the

redesign of their resource-use system with the aim

of reducing waste to zero. Put simply zero waste is an

idea to extend the current ideas of recycling to

form a circular system where as much waste as

possible is reused, similar to the way it is in nature ”
