What is in your waste bin? Banana peels, used napkins, a broken pencil? You may think they are useless waste. But they’re not: they are waste biomass! They are made of once-living things and they store energy. We can convert that energy into other forms and use it to light a reading lamp, cook a meal, or as fuel in our cars. Using waste instead of fossil fuels reduces air and water pollution as well. The best part is that we already produce so much waste, so why not use it?
There are four types of waste biomass. Different waste conversion technologies turn it into energy. We wanted to know which combination would give us the maximum benefits. We found that we can gain lots of energy back from waste to help the environment. However, the right type of waste and conversion technology could be different for each part of the USA.
