Fuelling industry and mitigating climate change

At WKE, we have made it our mission to develop a waste-derived alternative fuel that stands up to the challenges faced by heavy industry, including cement, power, steel and brick.

Used as part of your carbon-reduction journey or in place of conventional fuel altogether, solid improved recovered fuel (SIRF) pellets can help heavy industries boost their ESG profiles and make the world a greener place.

“Our goal is to produce a quality, stable and compliant fuel which will enable our customers to enhance their ESG scores with a cleaner energy at a lower cost.” – Ian Jones – CEO


About us


Power Station Icon


SIRF pellets have a significantly lower cost per gigajoule of energy, and the raw material is sourced locally.

Crane Icon


SIRF pellets offer stability in terms of specification and price, and benefits for companies reporting on ESG scores.

Cement Truck Icon


Gate fees for SRF could peter out. SIRF pellets offer a more consistent and ecological solution.

Brickwork Icon


As a substitute for natural gas in brickmaking, there are significant pollution-reducing benefits to using SIRF pellets.

By using biomass such as fibre, packaging and mixed wood materials from Commercial & Industrial (C&I) and Construction & Demolition (C&D) waste streams, as well as non-recyclable, low-chlorine-content plastics, we are able to produce a fuel that offers significant advantages in terms of both energy costs and environmental impact compared with traditional alternatives. By pelleting this material, we are able to make a fuel that can be transported easily and cost effectively for use in place of traditional solid fuels with little or no modification required to existing plants.

The pellets are produced from waste that is not physically or economically possible to recycle. Transforming and repurposing this material into fuel pellets stops this material going into landfill and provides end users with a high calorific value, low moisture and significantly reduced CO2 alternative to conventional fuels.
