Image by Walter Parenteau via FlickrSan Francisco recently approved the most aggressive recycling law in the United States. Residents will now be required to separate their garbage into three color-coded bins, blue for recycling, black for trash and green for composting. You read that right. San Francisco now has mandatory composting.
I think this is definitely a step in the right direction. Keeping this waste out of the landfill will cut down on landfill methane.
They’ve found that around 30 percent trash that goes to the landfill is compostable. But in landfill conditions, that waste is composting the same way it would in a home compost bin. In the landfill the piles don’t get to breath as much and the decomposition is Anaerobic. And the number one by-product of anaerobic decomposition is methane, a very potent greenhouse gas. If the production of methane can be reduced it would definitely help reduce our carbon footprint.
