There is that saying: if you garden, you'll eventually compost. The cycle makes sense - first you grow a bunch of organic matter, and after harvest the remainder of that organic matter is composted so it can be used to invigorate the next year's garden.
Even though not everyone gardens, just about everyone produces some degree of organic waste. Typically, this waste is thrown in with the rest of the non-recycled garbage and left to rot in the landfill. Once here, the potential energy and nutrients locked in the organic waste is pretty much lost forever. It is estimated that about 25% of our landfills are organic and food waste. If everyone had the opportunity to compost, we could drastically reduce what is sent to the landfills.
Denver Recycles has been piloting a paid-program for compostable items. Largely, the bins that go out are returned full of lawn waste (perfectly compostable). The program has been working with the participants to inform them about what is and isn't compostable in order to make them more informed about their waste management. However, since it is still in it's pilot program and being funded out of a general waste management fund, the Denver compost program is not yet available to everyone.
Denver Recycles is working with Denver Urban Gardens this summer to host free composting classes at the Gove Community Garden at 13th and Colorado. The classes will teach the basics of composting and everything you need to know about getting your own pile started. Some classes will also feature information on vermicomposting (composting with worms) which is ideal for those without access to outdoor areas. Schedules and signup dates will be available soon on the Denver Urban Gardens website.
