Is sorting recyclables from your trash worthwhile? Does grease or food contaminate a whole bin of recycling? A Stanford science journalist investigates, and the answers might be brighter than you think.
The United States generates more than 21 tons of food waste annually, and some of it is not compostable. A Stanford earth science student examines the garbage disposal versus the landfill to determine the most eco-friendly disposal route.
Outdoor composting is possible in any climate, and especially benefit gardens in the most extreme soils and temperatures.
In the United States, 34 million tons of food goes to waste each year. In 2009, only 1 million tons of that was recycled. But many Bay Area restaurants have found ways to waste not.
