Scientists turn trash into crude energy

Back to the Future Fan Club Magazine #1 - Winter 1989
Remember Doc Brown? That crazy, white haired caricature of a scientist from the 1980s blockbuster scifi comedy Back to the Future? He’s the inventor of a spectacular (and – sadly – fictitious) device called the flux capacitor that is running first on plutonium, later on ordinary household garbage to power a time machine. Here’s what it looks like when Doc Brown is searching for fuel:

Scientists in Denmark have now hit upon a novel way to do just that: producing energy from household waste. While not quite matching Doc Browns achievement when it comes to the amount of energy harvested (let alone building a time machine) the scientists’ feat is impressive enough:  Feeding  biomass (comprising anything from sewage, compost, household garbage or waste from meat and dairy production) into what is essentially a 400 °C hot pressure cooker they managed to create something very close to fossil crude oil. What’s more, the production process used is more energy efficient than any other way of getting energy out of biomass.

We figure, if the Danish research team is still unhappy with the energy yield of their trash, they only have to wait another two years for expert help: In Back to the Future – Part II we learn that Doc Brown is going to visit us in 2015.
