More and more, we see the words “compostable” or “biodegradable” on products. Do those words really mean anything or are they just greenwashing? Unfortunately, there is no simple answer. Composting is still relatively new in the mainstream with many communities now providing a compost bin along with their trash and recycling bins, and others opening up restrictions on backyard composting.As Americans, we throw away a lot of food and other compostable waste, in fact, compostables make up for a large amount of our municipal solid waste. A sad fact when you consider that all that organic material in a landfill just adds up to more methane emissions.
