In this anaerobic or oxygen-deprived environment, organic waste quickly breaks down into an acidic pre-compost through a process that’s similar to pickling. ... Step 5: Let Pre-Compost Rest.
Aerobic composting involves the decomposition of organic materials using oxygen and is the recommended method for home composting. [5] There are several benefits of aerobic (with oxygen) composting over anaerobic (without oxygen) composting such as less harmful byproducts.
The end product can also be moved to a secondary system – usually another composting step – to allow more time for mesophilic composting to further reduce pathogens. Composting toilets, together with the secondary composting step, produce a humus -like end product that can be used to enrich soil if local regulations allow this.

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.
Therefore, manure is required to be composted which will ideally kill any seeds or pathogens and reduce the ammonia content. [9] A large commercial compost operation. Chicken litter, which consists of chicken manure and bedding, is an organic fertilizer that has been proposed to be superior for conditioning soil for harvest to synthetic ...
Compost, which is aerobic, "burns up" much of the carbon into carbon dioxide to sustain the metabolism of microbes as it matures. Biogas production does not burn the carbon, but the bacterial culture is optimized to extract the carbon in the form of methane – a potent greenhouse gas and a useful fuel.
