The Fuel

Teal Energy’s fuel consists of processed biomass derived primarily from non-recyclable commercial waste, non-recyclable discarded wood and wood by products, paper and cardboard. People refer to this as waste biomass – it’s biomass that we don’t want to waste!

The raw materials are collected from businesses near the plant, sorted to remove any stray plastic, metals, etc., shredded and (if necessary) dried to a moisture content of about 20%. The resulting biomass fuel is in the form of a “flock”, that looks a bit like loft insulation.

The fuel is prepared locally to the generating plant and sent directly to the fuel storage bunkers (2) and the hence the gasifier by conveyor, to reduce transport movements and double-handling. This is supplemented by road deliveries to ensure security of supply (1). Each 20MW power plant will consume about 200,000 tonnes of waste wood and cardboard per year – that’s 200,000 tonnes that is no longer going to landfill.

The electricity produced by the plant is renewable because it uses biomass that would otherwise be wasted. The wood (including the cardboard!) absorbed carbon dioxide from the air when it was growing, which is released back into the air when we make electricity from it. The alternative – sending the wood and cardboard to landfill – also emits the carbon back into the air as the raw materials decompose, but without the benefit of producing electricity from it. The electricity we generate from the waste biomass displaces electricity that would otherwise be generated by burning coal.

So Teal Energy’s power plants reduce the total amount of carbon emissions in the UK.
