Vermicomposting uses worms to decompose waste and make nutrient-rich "worm manure". Vermicompost (vermi-compost) is the product of the decomposition process using various species of worms, usually red wigglers, white worms, and other earthworms, to create a mixture of decomposing vegetable or food waste, bedding materials, and vermicast.
Composter made from a hollow log. Composting is an important part of waste management, since food and other compostable materials make up about 20% of waste in landfills, and due to anaerobic conditions, these materials take longer to biodegrade in the landfill.
This site contains approximately 40 million tons of landfill waste since its initiation in 1986 until it was closed in 2009. [12] The Master Plan of the park is expected to include a meadow, a forest, terraces, and a Crown area that hosts the cultural, sports and industrial-commercial-poles, in addition to the 17 entrances to the park.

It differs from traditional composting methods in several respects. The most important are:

The daily cover on an operational landfill site is the layer of compressed soil or earth which is laid on top of a day's deposition of waste. Benefits of using daily cover include: [1] Reduction of odor and air emissions; Control of disease vectors (birds, insects, and rodents) Improved surface stability for landfill vehicles; Control of litter
