On Thursday, our recycling sub-team of the greater employee sustainability initiative hosted a seminar on composting. We were lucky enough to have Patricia Becker, Center Manager, and Neil Jensen, master composter, from Common Ground, an organic garden supply and education center in Palo Alto.
Common Ground has been in Palo Alto for 35 years and started the first recycling program in Palo Alto. Among CG's original founders were those famous gardeners, Smith and Hawken. You can learn how to compost at CG, and also buy starter plants and gardening supplies and take all kinds of classes in gardening.
For those of you don't know much about composting (and even those who do), we first go to the source - wikipedia of course, which describes composting as:
"Composting is the aerobic decomposition of biodegradable organic matter, producing compost. The decomposition is performed primarily by facultative and obligate aerobic bacteria, yeasts and fungi, helped in the cooler initial and ending phases by a number of larger organisms, such as ils, and other families representing ants, nematodes and oligochaete worms."
Composting is a great way to recycle the organic waste you create in your household and reuse it for vital nutrients for your garden and lawn. You can compost yard waste, food scraps from your kitchen, some paper, and other things depending on what type of composting you are doing. All this organic material turns into something that looks like dirt but is basically a superfood for your garden.
You might ask, but "Doesn't that stuff you mentioned just biodegrade in landfills?"
No, not really....Landfills pack in all the garbage - whether organic or plastic or metal or anything else - so tightly that it doesn't get the oxygen it needs to degrade naturally. This isn't a new phenomenon either - archeologists have done studies of ancient societies by digging up their garbage dumps.

But, "it really isn't a big part of my garbage, is it?"
Again, no....a study by the EPA in 2006 said that 25% of solid waste collected by municipalities in the US is food waste and yard trimmings.
So, obviously organic waste like food scraps and yard trimmings are a big opportunity for recycling.
And it's not just something only people with huge large backyards can do. It is easy to compost in small backyards. There are even solutions for composting in apartments and houses with no backyards. The nice thing about composting is that the material you put in is reduced to 1/3rd of its original amount during the composting process - so you won't end up with more compost than you need.
Note to San Francisco Residents: The city compost for you - just get the Green Bin. House residents can get one for free from their waste management company. Apartment dwellers, ask your landlord to get a green bin. Check out more info below.
