Vermicomposting

Vermicompost is the process of composting using various worms usually red wigglers, white worms, and other earthworms. These worms are used to create a heterogeneous mixture of decomposing vegetable or food waste, bedding materials, and vermicast.

The process of breaking down organic material, such as dead plant or animal tissue, into smaller molecules that are available for use by the organisms of an ecosystem. Decomposition is carried on by bacteria, fungi, protists, worms, and certain other organisms.

Fermentation, a chemical process by which molecules such as glucose are broken down anaerobically.

Annealing is a process of heat treatment that increases the temperature of the metal to a certain value and holds it for a particular time period.
