Tonnes of human toilet waste recycled to help put food on the nation's tables
Hundreds of thousands of tonnes of human toilet waste from London is being recycled to help put food on the nation's tables.
The raw sewage is turned into fertiliser, known as a biosolid, before being sold to thousands of farmers.
Thames Water converts 275,000 tonnes of 'wet sewage' from London treatment plants every year.The strictly-controlled organic process allows toilet waste to re-enter the food chain in an eco-friendly way.
Thames Water said demand for biosolids outstripped supply because the product is cheaper than chemical fertilisers.
The biosolids undergo a series of checks, including tests for the bacteria Ecoli, before being transported to farms in the Home Counties.
