They also utilize thermal energy from the process to assist in heating nearby buildings in the colder months... good stuff!

The Cincinnati, Ohio-headquartered retailer expects the system will process more than 55,000 tons yearly of unsold organics and food processing effluent, roughly 150 tons per day. The energy produced will provide 20% of the energy needed by the distribution center, the company said in a news release. "Investing in this project is a good business decision for Kroger and, most importantly, an extraordinary opportunity to benefit the environment," Rodney McMullen, President and COO of The Kroger Co., said in a statement.

While it may be the easiest method, it takes a really long time to finish and it has different environmental consequences...more on that in a moment. A popular method I've read about is to use two thick black garbage bags, a bucket to measure out the contents and some water. Add equal parts shredded food scraps (no meat/dairy/seafood), soil+some finished compost, and "brown" materials (shredded leaves, shredded paper). Add some water to get the material damp, but not completely soaked. Tie off the bag, then put it inside the other garbage bag and tie that off, too. All done! This process is often said to…
