Waste to Energy in London
Waste to Energy (WtE) is the process by which waste materials that are too small or contaminated to be recycled are converted into energy such as electricity, steam or heat. The fuel produced is known as Refuse Derived Fuel (RDF) or Solid Recovered Fuel (SRF).
The McGrath Group were early adopters of the technology and pioneers of the UK’s WtE sector. We have been supplying RDF/SRF to recovery facilities since 2011 and the environmental benefits of the process make this a growing area of our business.
Our facility is one of the UK’s most sophisticated of its kind which supports our commitment to apply the waste hierarchy by diverting unrecyclable wastes from landfill. Our technology for processing waste residues ensures we create the best quality RDF/SRF with high calorific value. The process is fully sustainable with high energy yields which in turn reduces the burden on natural resources.
Our thorough pre-treatment separation and processing systems ensure a superior high grade final RDF product. Waste consignments tipped at our MRF in Greater London are processed to extract any metallic or mineral items. The non-mineral residues are then bulked and subject to chemical sampling tests to determine the moisture content, ash content, net and gross calorific value plus other inorganic tests which are required by regulators for export purposes.
The residues are baled using our bespoke, integrated cross-wrap plant into durable packages for safe and secure transportation to WtE facilities on the continent for processing. Using our wharf waste facilities, we are able to deliver the consignments directly by sea. This reduces lorry journeys, traffic congestion, fuel consumption and pollution.
We have developed established channels to a number of facilities in Europe where our regulatory compliance (EA, TFS, Financial Bonds and Insurance) is part of the necessary and stringent requirements.
At these plants the RDF is incinerated in a controlled environment to produce electricity for the local electricity grid and steam to heat local industry and businesses.
The combustion gases are only released after being cleaned by flue gas cleaning systems. The ash generated is recycled while other residues are used in road and cement production.
