Waste-generated biogas is turning homes into power plants.

Waste-generated biogas is turning homes into power plants.Sandra Sassow wants to talk about sticky subject of waste. Just the word, the umbrella term for our uneaten – or indeed, post-eaten – food carries the whiff of dismissal (among other things). What’s in those bin bags? Just waste. What about the septic tank? Waste. Nothing of value. But ‘waste’ – at least most of it – isn’t just some unavoidable byproduct of human life, that accumulates until the council turns up to put it out of sight and out of mind once a week. If you can get past the ‘yuck’ factor, it could be what powers your home, apartment block, supermarket, workplace or even your hospital.
