The document discusses two types of composting: vermicomposting using worms and hot composting. Vermicomposting uses red wriggler worms to break down food scraps, providing the worms with moisture, darkness, and temperatures between 55-77 degrees F. Hot composting involves building a pile with the proper carbon to nitrogen ratio and turning it regularly to raise the temperature to 130-140 degrees F, allowing compost to be ready in 2-6 weeks. The document also mentions building a three-stage compost pile and collecting food wastes from a cafeteria.
