Our Recovery Services

‘Recovering’ Energy from Waste

There is energy in everything – even in waste! Harnessing this energy releases valuable commodities such as heat, electricity, transport fuel and fertiliser. Our Greener Path Programme will help you ‘Recover’ the energy in your waste. With no capital outlay required, it will ensure you get every last penny out of what you do use, and what you don’t!

Energy from Waste (EfW)

Energy-from-Waste (or waste-to-energy) facilities generate power by burning waste such as food, wood, paper, plastics and mixed household waste. Put simply, burning the waste creates steam, the steam drives turbines, the turbines generate electricity and the electricity is fed into the national grid.

Anaerobic Digestion

Anaerobic digestion uses naturally occurring bacteria that can grow without oxygen to break down organic waste. The process produces biogas (a mixture of methane and carbon dioxide), a renewable energy that can be used to make heat, transport fuel and electricity.

Aerobic Digestion

Aerobic digestion is the natural biological breakdown of organic waste by bacteria in the presence of oxygen. It is a simple process that produces biogas, water and organic material (known as digestate). As in anaerobic digestion, biogas is used to produce heat and electricity while digestate is used as a fertiliser. Once treated, water can be returned to our rivers and streams.

Refuse Derived Fuel (RDF)

Through our unique network of approved suppliers, we have now secured preferred access to 32 Refuse Derived Fuel (RDF) facilities across the UK.  This means we can provide even more cost-effective, sustainable choices when it comes to your waste operation.


Using these new RDF facilities will safeguard you against ever-rising landfill taxes and reduce the impact your organisation has on the environment.

What is Refuse Derived Fuel?

RDF refers to the residual waste after all recyclates have been extracted, to be used as a fuel. An increasing number of new generation energy plants have been built to convert this ‘fuel’ into electricity. This provides a significantly more sustainable option than landfill.

As with all our programmes, recovery and recycling is at the core, and the aim is to recover as much material for recycling from your waste before considering the option of RDF.

This means the fuel being created is only produced from materials that either cannot be recovered or are too contaminated to be sustainably recycled.

RDF can be used in a variety of ways to produce electricity. It can be used alongside traditional sources of fuel in coal power plants and in the cement kiln industry.  RDF can also be fed into plasma arc gasification modules and pyrolysis plants.



Solid or Specified Recovered Fuel (SRF)

Like Refuse Derived Fuel, Solid Recovered Fuel is produced by shredding and dehydrating solid waste using a waste converter. SRF is dry, with a high energy density, and it can be compressed into bricks, pellets or logs for ease of burning. It is used to produce electricity.
