Producing energy and car fuel from livestock waste: it sounds too good to be true, but this is what is happening on this farm near Piacenza, in Italy's Emilia Romagna region."Over the last few years, we have started a project that is allowing us to produce renewable energy and to have an actual circular economy," says owner Nicoletta Cella."I mean, we can produce energy from animal excrement and livestock waste, along with agricultural by-products.""We produce bio-sustainable fuel from our livestock waste and the idea of us, an agricultural company, being able to input it into the transport system is extremely gratifying on a personal level," said CellaThe gas station opened last February, a couple of weeks before Russia invaded Ukraine and the subsequent surge in the costs of energy and fuel.Last year, a coalition of countries signed the first global commitment to cut methane emissions by at least 30% below 2020 levels by 2030 at the UN climate conference COP26 in Glasgow."
