Waste processor RenECO currently works with Sainsbury's to turn food waste that can’t be donated or used for animal feed into biogas via anaerobic digestion. This circular system will now use the output of this anaerobic digestion, the biogas, to create a liquid biofuel suitable for HGVs.
Unlike traditional methods that mix certified biomethane with non-renewable gases, this system ensures all fuel comes directly from Sainsbury’s waste. By working together, the retailer and supplier have shown how collaboration is key to unlocking new ways of reducing environmental impact.
The circular system also allows for precise tracking of carbon emission reductions, contributing to Sainsbury’s scope 1 & 2 emission reduction target.
Patrick Dunne, Sainsbury’s Director of Property, Procurement, and EV Ventures, commented, “Today’s announcement underscores the power that collaboration has in driving impactful change across business.
'We are proud to have worked closely with our supplier RenCo to deliver a pioneering move that supports our commitment to circularity and helps us to take a further step towards becoming net zero across our operations by 2035.”
