Our Waste-to-Energy Process

CoGen has developed a series of advanced technology Waste-to-Energy (WtE) facilities in Birmingham, Plymouth, Northamptonshire, Stoke on Trent and Cheshire.

Using a range of advanced WtE conversion technologies, each facility receives between 40,000 and 200,000 tonnes of Refuse Derived Fuel (RDF) each year.

The advanced WtE conversion technology processes the feedstock as follows:

Feedstock undergoes off site preparation by specialist suppliers
Now a prepared fuel, the feedstock is further screened and stored on site
The prepared fuel is then stored and fed into one of the gasifiers where it is heated under carefully controlled conditions to form a fuel gas
This fuel gas is then passed into a boiler for energy conversion, with the resultant steam being sent to a turbine for energy recovery

The CoGen WtE facilities treat prepared fuel to recover a number of valuable products including:

  • Renewable Electricity 4.5MWe to 25MWe depending on facility
  • Renewable heat for local business
  • Metals for recycling

The renewable electricity produced from just one of our 10MWe facilities is sufficient to sustain 25,000 houses (OFGEM).

Each facility is regulated by the Environment Agency to the strictest environmental standards and they each comply with the Renewables Obligation as an Advanced Conversion Technology Facility.
