Biofuel Crops to be Fertilized By Landfill Ooze

Landfills aren’t just dumping grounds. All that rot can produce usable energy. Many landfills are already prized turf with methane being used as a fuel source, and cellulosic biofuel plants pillaging the refuse headed towards landfills as feedstock.

But there is a whole other use for the ooze that comes from landfills. It’s headed towards nourishing plant life that will turn into biofuel.Rotting material creates a liquid called leachate, a liquid that sometimes is left to seep into ground water, and sometimes is piped into lagoons where it can be processed or cleaned up. A developer from Waste Recycling Group wants to use those lagoons as energy generators, where bacteria can eat away at the leachate and eventually turn it to fertilizer. The fertilizer they produce will be used to grow willow coppices, which will be used for biofuel.

It will be an on-site crop, and will help make full use of the landfill space. The project still has to go through approval, but should it get the thumbs up, it’ll be an interesting venture to follow.
