How Cities Are Turning Food Into Renewable Fuel
Every year, America throws away more than 80 million pounds of food. More than three-quarters of it ends up in landfills, where it takes up more room than any other kind of waste and produces as much greenhouse gases as 3.4 million vehicles.
The food waste that doesn’t end up decomposing at the dump is most commonly diverted to compost facilities that turn organic material into nutrient-rich soil. But an increasing number of municipalities around the country are looking to do even more with this untapped resource by turning it into usable energy called biogas.
