Summary:

Used coffee grounds from a campus coffee shop are being used as compost to cultivate gourmet mushrooms at a student farm. By composting alone, 50 pounds a week -- or about 30 percent of the coffee shop's total waste -- has been diverted from landfills. While developing the compost program, the researchers made an important discovery: coffee grounds are a great compost for cultivating mushrooms, particularly gourmet mushrooms, such as oyster, shiitake and reishi. The U.S. gets nearly 45 percent of mushrooms from China, and there is a need for more local suppliers of gourmet mushrooms, said one researcher.

With the current world price at 90 cents a pound is making profitability in many countries nearly impossible With production cost at about $1.50 per pound. The shortest answer is to grow more coffee witch takes more land, ,fewer trees, more c02, additional climate effects . Climate change and general weather unpredictability are one of the driving forces in the roller coaster ride coffee prices are having and will likely continue to have in the foreseeable future. Perhaps second only to the never ending political unrest in many coffee growing regions.

With the environment in the news lately. Here is one you didn't see coming. Used coffee grounds are very good at storing Methane. Methane is a global warming gas many times more potent that carbon dioxide.With Methane having one advantage over Carbon Dioxide. That is Methane can be used as a fuel. The process to make this work is relative simple with the moist used coffee grounds being heated with potassium hydroxide. So who cares you may be asking yourself. While It's not likely your local power company will be digging around in your trash ben for your used coffee grounds in order to capture and store their Methane emissions. Some smaller producers of Methane emissions may have some interest. Many oil wells also produce small amounts of natural gas. The volume of gas is so small that it's uneconomical to lay the needed pipe in order to place this gas into the natural gas lines that heat your home. So this g...
