Yard waste debris such as grass clippings, leaves and tree prunings are estimated to make up 18% by weight and 10% by volume of the municipal solid waste stream. During the growing season, yard waste can amount to 50% or more of the residential solid waste stream in some Indiana communities.
Yard waste not only takes up valuable landfill space, but can contribute to landfill gas production, acidic leachate production and settling problems as well. Yard waste also reduces the efficiency of incinerators because of the waste's high moisture content. Keeping yard waste out of the trash truck saves money and protects the environment. Yard waste is banned from Indiana's landfills and the open burning of leaves and other yard waste is restricted in Indiana.
