Compost and Mulch

Composting, nature's own way of recycling, is the controlled decomposition of organic material such as leaves, twigs, grass clippings, and vegetable food scraps.

Compost is the soil amendment product that results from proper composting. Whether it's done on site, at the point of waste generation or in a large-scale, centralized facility, composting helps to keep the high volume of organic material out of landfills and turns it into a product useful for soil restoration.

On-site composting reduces the cost of hauling materials and is generally exempted from solid waste regulations. Large-scale compost facilities handle more material and typically produce a more consistent product, and they are required to comply with regulatory and permitting standards.

Below are links to information for specific audiences and their needs related to compost and mulch.
