With the aerated static pile technique, the raw material mixture is piled over a base of wood chips, chopped straw or other very porous materia. The porous base material contains a perforated aeration pipe. The pipe is connected to a blower, which either pulls or pushes air through the pile.

The turning operation mixes the composting materials and enhances passive aeration. With the wind-row method, the active composting stage generally lasts three to nine weeks depending upon the nature of the materials and the frequency of turning. Eight weeks is usual for manure composting .

Compost is organic material that can be added to soil to help plants grow. Food scraps and yard waste currently make up 20 to 30 percent of what we throw away, and should be composted instead. Making compost keeps these materials out of landfills where they take up space and release methane, a potent greenhouse gas. Browns - This includes materials such as dead leaves, branches, and twigs. Fats, grease, la.

In-vessel methods rely on a variety of forced aeration and mechanical turning techniques to accelerate the composting process. Many methods combine techniques from the wind-row and aerated pile methods in an attempt to overcome the deficiencies and exploit the attributes of each method.

Red wigglers are the most common form of worm used in vermicomposting, however, earthworms or native worms can be used. Each species of worm will differ in production of castings. Most common variety used is. Red worms technically graze on the mic.
