<human>:  Please give me 3 different kinds of composting techniques.
<bot>: 
1. Hot composting: This is where materials are mixed together in a pile to allow for higher temperatures and faster decomposition.
2. Cold composting: This is a slower method, where materials are laid in layers and mixed together until the compost is created.
3. Vermicomposting: This is an organic process where worms are used in mixing and decomposing the material to create compost.
