Bio-fertiliser made from human urine helps crops grow just as well as widely used synthetic alternatives, according to new studies by agricultural scientists.
The independent research, carried out by the Royal Agricultural University (RAU) and UK AgriTech Centre, is a major milestone for Bristol-based startup NPK Recovery which extracts nutrients from urine collected at public events such as the London Marathon and Bristol Pride.
