In large part, disposal of yard trimmings-such as grass clippings and trimmings from bushes, uses, and other yard vegetation-in landfills is generally not necessary, since backyard composting and yard trimmings collection and recovery programs have become quite popular. Composting yard trimmings saves landfill space and reduces methane production in landfills. Methane gas can contribute to global climate change.

Natural composting, or biological decomposition, began with the first plants on earth and has been going on ever since. As vegetation falls to the ground, it slowly decays, providing minerals and nutrients needed for plants, animals, and microorganisms. Mature compost, however, includes the production of high temperatures to destroy pathogens and weed seeds that natural decomposition does not destroy.
