More than 750,000 tonnes of liquid from landfills are mixed with sewage at water treatment works and spread on farmland across England each year, it can be revealed.
Generated by hundreds of landfills across the country, leachate – the liquid that drains through landfill waste carrying a cocktail of chemicals – is regularly tankered to sewage treatment works, where it mixes with domestic sewage and industrial effluent to create sludge, also described as “biosolids”.
