Waste to Energy

The treatment and disposal of organic waste is an ever- increasing problem. Organic waste disposed to landfill is often banned and the spreading of waste to land, where allowed, requires extensive permitting.

Organic waste can be ‘stabilised’ so that it will not degrade further by two distinct biological processes. These are aerobic composting and drying or anaerobic digestion. The advantage of anaerobic digestion is that it is a net energy producer in the form of biogas whereas composting requires energy to aerate the waste so that the process can take place.

The pre-treatment of waste, before anaerobic digestion, can be a large part of an overall plant process and will depend on the form the waste is supplied in. Farm wastes and on-site food production wastes may require minimal processing.

Commercial waste and source- separated household waste will require more de-packaging and pasteurisation etc. Black bag bin waste will require a full Mechanical Biological Treatment (MBT) plant with Anaerobic Digestion.

In all cases, the biogas conversion to heat and power will provide a significant, if not the majority of income for the processing plant. Therefore, it is essential to extract the best value from the gas produced. To achieve this, a high efficiency electrical conversion unit is needed but with the confidence in the technical backup from the supplier to give reliable continuous operation over the project lifetime.
