Converting garbage to energy – In a world where we need more and more energy but worries are arising in the way we get that energy (ideally we want it clean, not dirty like oil sand and arguably LNG) the idea that we could create energy from our trash is quite an interesting one.
While not always strictly a ‘green’ emission free energy there are possibilities in the realms of energy reuse and even use of old garbage buried deep under the ground that could be good alternatives and at least in small part help reduce some dependence on oil.
So what possibilities are there when it comes to turning garbage into energy.
Gas from old garbage dumps – This is being done right now, companies are literally sticking pipes down into old rubbish dumps and letting the gas flow out to be used as energy. There is no reason I can see why we shouldn’t use all this gas up. We put it there, we created it and it’s probably better out than in and in my opinion certainly better than breaking open the natural rock beds for gas.
Gas at home from trash – Using fairly simple systems which basically comprise of a few large plastic drums and a bacteria ‘tea’ starter (cow poop is good), you can start the process of turning your everyday green waste into gas that can be used for heating and cooking. I’ve seen systems that are so efficient that the owners have had to let gas off into the air every now and then because too much is building up.
Here is a video from someone I knew who uses biogas from his home in Garbage City, Cairo.
Of course there are even more ways to make energy from garbage but these are just a few. The world over is starting to innovate in this field because the more we can make use of our own waste the better for our own planet.
What ways do you know? Does this field of energy production excite you?
