Why Composting Food Waste is NOT the Environmentally Friendly Solution!
Several in the sustainability field have asked why someone would invest in a BioSoil Farm Food Waste Recycling Center instead of simply shipping their food waste of to be composted. Good Question. Here is the answer…
Food Waste and Organic Waste shouldn’t go to a landfill for disposal because in a landfill the organic waste (food waste, paper, etc) creates methane gas as it breaks down in an anaerobic environment. In fact, every pound of organic waste disposed of in a landfill, creates more than 2 lbs of methane gas.
So, instead of sending food waste and organic material to the landfill, many suggest simply sending it to a compost facility. Sounds good. Composting is good for the environment, right??
WRONG! Composting at home is one thing. Home based composting is environmentally friendly. Commercial composting and industrial composting however are not. Why?
Well, industrial and commercial compost facilities are only a little better than landfills. First of all, compost facilities have to clear cut a lot of space. That space probably was occupied by trees and plants that, until cut, were cleaning the air. Secondly, when organic waste breaks down in the aerobic environment of a compost facility it releases CO2. The CO2is less potent green house gas than Methane from a landfill but it is still a green house gas and it lives in the atmosphere much longer than methane. So while CO2 release from a compost facility is less potent than methane from a landfill, both solutions release troublesome green house gasses. Home composting units are usually around a lot of trees and plants so the CO2 released in the process is often mitigated by local greenery. Because compost facilities take up a large amount of space, there is often very little tree canopy to capture the CO2 and sequester the carbon. So commercial composting facilities are only slightly better than landfilling.
Additionally, most compost facilities can not handle ALL organic waste, as adding animal by-product to the compost pile makes the composting much more difficult. Animal by-products and post-consumer food waste don’t work well in compost piles.
Lastly, compost piles require very tight carbon to nitrogen balancing meaning that lots of additional waste needs to be brought in to make the compost pile work.
So, if landfilling and composting are just about equally damaging to the environment, what is the solution for recycling or remediating food waste and other organic waste?
BioSoil Farm’s Food Waste Recycling Center is the most environmentally friendly option. Our Food Waste Recycling Centers process food and organic waste in a closed unit in about 15-19 hours. No methane is produced. No CO2 is released. The food waste is simply dehydrated and broken down into the raw material for our organic, sustainable fertilizer andour renewable fuel made from organic waste.
