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.

Used coffee grounds can help stop global warming.

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...

Meat and climate change. One side of the story.

What do you think? This is one side of the story. Meat production is a major contributor to climate change. It is estimated that livestock production accounts for 70 per cent of all agricultural land use and occupies 30 per cent of the land surface of the planet. Because of their sheer numbers, livestock produce a considerable volume of greenhouse gases (such as methane and nitrous oxide) that contribute to climate change. In fact, the United Nations Food and Agriculture Organization (FAO) has estimated that livestock production is responsible for 18% of greenhouse gases. The growing of livestock and other animals for food is also an extremely inefficient process. For example, it takes approximately five to seven kilograms of grain to produce one kilogram of beef. Each of those kilograms of grain takes considerable energy and water to produce, process, and transport. As meat consumption has grown around the world, so has its climate impact.
