Saria Bio-Industries has completed a £8m (US$11.6m) investment in building the world's first animal bio-diesel plant, and is now able to produce 2.8m gallons of diesel a year from animal carcasses. Germany-based Saria operates 30 bases and rendering plants across seven European countries, including France, Austria, Poland, Spain and the Czech Republic. It renders 2.5m tons of carcasses and animal waste a year, but had to cease turning fat from cattle carcasses into animal feed because of the BSE crisis.
