Energy From Food Waste

One of our Biomimicry Principles that we live by from the book by Dr Tamsin Woolley Barker called TEEMING: Principles of Biomimicry as Compassion in Action in accord with Nature: We cultivate Collective Intelligence by:

  • Aggregating scattered scraps into something greater.

We really don't need to use a lot of energy. Methane is 25x more destructive than CO2. How do we capture this waste stream of Methane simply and cost effectively. This could be done on an individual level or on a community level. Right now all of my scraps are going into the worm bins. They are loving it! I wonder could we put worms in a methane digester without killing them? Anybody?

We could power households from the scraps in our food waste bins, so what's stopping us Imagine if you could power your kettle using the energy generated from the vegetable cuttings quietly breaking down in your kitchen's compost bin. That reality might not be so far off with the growth of biogas technology.

Biogas: Converting Waste to Energy | White Papers | EESI The United States produces more than 70 million tons of organic waste each year. While source reduction and feeding the hungry are necessary priorities for reducing needless food waste, organic wastes are numerous and extend to non-edible sources, including livestock manure, agriculture wastes, waste water, and inedible food wastes. When these wastes are improperly managed, they pose a significant risk to the environment and public health. Pathogens, chemicals, antibiotics, and nutrients present in wastes can contaminate surface and ground waters through runoff or by leaching into soils. Excess nutrients cause algal blooms, harm wildlife, and infect drinking water. Drinking water with high levels of nitrates is linked to hyperthyroidism and blue-baby syndrome. Municipal water utilities treat drinking water to remove nitrates, but it is costly to do.

After methane leaks, it is over 80 times more potent than carbon dioxide in its ability to warm the planet over a 100 year period.
