Our energy from waste process


Here at Powerday we’re always looking to be at the cutting edge of waste collections and disposal, part of which includes ensuring that your waste is utilised in a way that most benefits the UK.

Energy from waste is a process which is helping to drastically cut the amount of waste sent to landfill, with the additional benefit of securing energy from these once discarded resources. Now, with the ability to extract energy from even the non-recyclable or reusable materials, we’re helping to avoid wasting the opportunity held within this resource.

How we supply the energy from waste process

Initially, we work to recover all the reusable and recyclable materials in the waste which comes into our Old Oak Sidings and Enfield sites, including plastics, metals, bricks and blocks. We then take all the material left over - usually a mixture of plastics, paper and packaging fragments - to create what is known as Refuse Derived Fuel (RDF).

Once we have processed the material, we then supply it to energy from waste plants. At each plant, they will receive the materials at a dedicated reception point, which is where they will prepare the materials for combustion.

Here the materials are subjected to what is called thermal treatment, which is the process which helps to release the energy from the RDF brought in from different waste companies. This then allows for the conversion of energy into a transportable form, which can come in a number of forms depending on the type of facility. Electricity, gas, heat and other fuels can all be created to help power the energy industry.

Clearly the issue of emissions comes into the process, which is why plants perform an emissions clean-up phase, making any waste gases safe before they do damage to the environment.

There are many factors involved with how well a plant performs, the most important of which is the efficiency of the plant. Plants need to apply the most efficient processes and technology in order to get the most from RDFs, increasing how environmentally friendly the process is. Continuing investment in infrastructure and improvements can only be a positive, allowing us to get the most from RDFs.

The alternative here in the UK to creating and utilising RDFs in the energy from waste process, is to send the waste to landfill. This is something which the world needs to avoid at all costs, which is why we’re so dedicated to furthering the efficiency and quality of the energy from waste process.
