up to 500 HGVs in a single day .
“ By being connected to the high pressure system , it means the carbon footprint is much lower when compared to other filling stations ”, Zennaro adds .
With their large cumulative quantities of food waste , and long-distance transport needs , major supermarket chains have naturally started to notice the potential of biomethane . Waitrose is already powering two of the Scania tractors used at its regional distribution centre at Leyland using compressed biomethane from the nearby filling station .
Not to be outdone , Sainsbury ’ s has recently partnered with recycling and waste management company ReFood to power a handful of its stores with biomethane . Under the partnership , ReFood will collect food waste from two of the supermarket ’ s depots , convert it into gas and fertiliser at one of its anaerobic digestion facilities and inject the biomethane into the grid . A third party will then export the gas to select Sainsbury ’ s locations where it will be used to generate carbon-neutral heat and electricity .
“ I think we ’ re seeing an increased interest from energy consumers , from corporate companies like Diageo and big supermarkets ,” says Zennaro of biomethane ’ s growing appeal . “ So far they ’ re mainly interested in green electricity , but now the green gas element is starting to raise more interest .”
