Compost is produced when organic matter, such as kitchen and lawn waste, is broken down by microorganisms.
As much as 50% of the waste produced by North Americans consists of organic material which can be composted. Approximately one third of the garbage in landfills is made up of compostable materials. As such, composting represents an opportunity to significantly reduce waste.
There are a number of benefits to composting:
Compost enriches soil
The beneficial microorganisms in compost break down organic matter to create humus. Humus increases the nutrient content in soil and helps soil retain moisture.
Compost helps clean up contaminated soils
The composting process has been shown to absorb odors and toxic chemicals, such as volatile organic compounds. It also binds heavy metals, thereby keeping heavy metals out of water resources.
Compost helps prevent pollution
Composting keeps a significant amount of waste out of landfills. As such, it prevents the production of methane and leachate in landfills. Compost also helps prevent pollutants in stormwater runoff from reaching surface water resources.
Compost offers economic benefits
Using compost can lower gardening costs by reducing the need for water, fertilizers, and pesticides.
Composting can be done both at work and at home. Look for a private or government agency on your area to get more details on composting at home or in the office. |
