Waste Streams We Work WithTurning Waste Challenges into Feedstock Opportunities

As the waste sector shifts away from disposal to material recovery, improving feedstock quality becomes vital to unlocking new offtake markets.

Clean, consistent feedstock is particularly important for pursuing plastics chemical recycling and Sustainable Aviation Fuel (SAF) production at scale.

For waste handlers seeking alternative ways to process challenging streams, this presents a real opportunity. Waste previously classed as ‘end-of-road’ -often destined for landfill or EfW due to contamination and sorting challenges -can now re-enter value chains. With the right pre-treatment technologies, residual waste can become homogenous feedstock, transforming it from a costly liability into a valuable resource suitable for high-value offtake routes.

Our biotechnology offers a commercially and environmentally responsible way to help unlock that value , enabling waste handlers to turn mixed plastics, organic fines, offensive washroom waste, and de-packaged AD waste into valuable feedstock. By removing moisture, odour and the organic fraction of waste, clean, consistent floc (or feedstock) with a high calorific value is created. This floc not only negates the need for landfill, but it also opens the door to chemical recycling and SAF as offtake routes.

Giving producers what they need

Chemical recyclers and SAF producers require clean, consistent feedstock to scale and achieve higher yields and higher-quality products but securing a steady supply can be challenging.

Chemical recycling and SAF production sit between disposal and true circular recovery, creating value from waste typically deemed worthless. In many ways, these methods act as the bridge between waste handling and advanced material recovery – transforming contaminated residual streams into feedstocks that can replace the fossil fuel components used in plastics and aviation.

Our recent Waste Summit, in partnership with Letsrecycle.com, reiterated the opportunity these routes present when pre-treatment technologies are harnessed. Chris Wilson from Mura Technology explained how their hydrothermal process can accept plastics with contamination, food residues and multilayer films, which mechanical recycling cannot. Similarly, our own Chief Strategic Development Officer, Dr Stephen Wise, discussed Advetec’s biotechnology as a form of pre-treatment, able to create homogeneous floc with increased calorific value, which is ideal as an alternative fuel or for further processing into SAF or chemical recycling.

Reducing fossil fuels and moving closer to circularity

Reaching a truly circular economy will require significant infrastructural investment, supportive policy, long-term behavioural change and time. But there is still much we can do now. Maximising the materials already in circulation and recognising value in every waste stream are vital parts of that journey. Chemical recycling replaces virgin fossil fuel in plastic production, while SAF offers a lower-carbon alternative to fossil-based jet fuel. Both drive carbon reduction today.

Speaking after the Waste Summit, Dr Stephen Wise said: “Traditionally, the waste market has been push-based with a focus on disposal at the lowest cost. The growing chemical recycling and SAF markets are changing that, creating pull and highlighting waste as a commodity.

With the right pre-treatment, today’s hard-to-handle waste can become the fuel of tomorrow. By improving feedstock quality, waste handlers can unlock new revenue streams, reduce costs, support the growth of chemical recycling and SAF, and play a pivotal role in accelerating the move to greater circularity.
