  2. What is Composting • Composting is a natural process that turns organic material into a dark rich substance. This substance, called compost or humus, is a wonderful conditioner for your soil. • What are organic materials: fruits and vegetables, eggshells , coffee grounds, grass clippings, yard trimmings, leaves, wood chips, sawdust… • Four important ingredients: • Green materials (Nitrogen) • Brown materials (Carbon) • Moisture (Water) • Air (Oxygen) • Carbon-to-Nitrogen Ratios

  3. Why Composting • 25% of garbage in the U.S. is made up of yard trimmings and food scraps • It fills up more and more landfills • Landfill methane is a greenhouse gas that cause global warming • When landfills are rained on, the runoff pollutes lakes, streams, and groundwater sources.

  4. Different Type of Composting • Aerobic composting: the decomposition of organic matter in the presence of oxygen. This type of composting doesn’t emit an unpleasant odor and, with the proper conditions, can be completed in a span of two weeks. • Anaerobic composting: is a series of processes in which microorganisms break down biodegradable material in the absence of oxygen. • Vermicomposting: is the process of using worms to break down organic waste.

  5. Large Scale of Composting • In-Vessel Composting System • City Compost Bin • City of Allen is doing a good job on curbside yard debris and leaf collection programs
