How Gasification Turns Waste Into Energy

Turning waste into energy has usually meant incineration - that is, burning our trash. But this method has major environmental drawbacks. Gasification could be a better alternative. It’s an old technology that proponents hope to repurpose as a cleaner and more economical waste-to-energy solution, and now a number of companies in this space say they’re on the verge of commercialization and expansion. We produce over 2 billion tons of waste per year, a number that's expected to grow by 70% by 2050. We've long sought ways to turn all this waste into energy, but this has usually meant incineration - that is, burning our trash - a method that many environmentalists say is far too polluting. A better solution may lie in gasification, an old technology that advocates are trying to repurpose as a way to deal with our waste. Gasification companies don't burn trash, instead they turn into a synthetic gas, in a process they say is both economical and eco-friendly. This synthetic gas can then be converted into a wide variety of end products like electricity, diesel fuel, hydrogen fuel, or ethanol, depending on whats most valuable in any given market.
