Home composting

Home composting is the managed biological decomposition of suitable household organic materials at or near a residence. By combining carbon-rich and nitrogen-rich materials with adequate moisture, oxygen, and time, people create a soil-like amendment while diverting accepted food scraps and yard materials from disposal.

In simple terms

A home compost pile or bin needs a workable mixture of dry, carbon-rich materials and moist, nitrogen-rich materials. Chopping inputs, maintaining moisture, and turning or otherwise allowing airflow can support decomposition and limit odors. Not every organic-looking item belongs in a household system: feedstocks should follow reliable local guidance, and a product described as Compostable may require industrial conditions. Home composting complements Waste prevention; avoiding unnecessary food and material use comes before managing the remaining suitable organics.

Why it matters

Keeping suitable organics out of disposal can return nutrients and organic matter to soil and reduce the volume of household waste requiring collection. Poorly managed piles can attract pests, smell, or decompose slowly, so input selection and maintenance matter. The finished compost should be mature before it is applied around plants.

Example

A household layers dry leaves and shredded uncoated cardboard with fruit and vegetable scraps in a ventilated bin. It keeps the mixture damp rather than saturated, mixes it periodically, excludes materials discouraged by local guidance, and waits until the material is dark, crumbly, and stable before using it in a garden.

How it differs

Compostable

Compostable describes a material's ability to break down under specified composting conditions; Home composting is the household-scale process, whose conditions may not suit every compostable product.
