Biogas

Biogas is the mixture of gases produced by the breakdown of organic matter in the absence of oxygen Biogas can be produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste Biogas is a renewable energy source.

Biogas

Often, biogas plants that treat wastes originating from animal material, will also require the material to be treated at high temperature to eliminate any disease causing bacteria in the slurry These systems pasteurise the slurry, typically at 90C for one hour, to destroy pathogens, and result in the provision of clean, high quality fertiliser.
