The video tutorial by Mr. Treville, also known as the Great Trevolini, explains the process of composting kitchen waste into rich soil using decomposers like bacteria and worms. It highlights the importance of recycling nutrients such as sulfur, phosphorus, oxygen, nitrogen, carbon, and hydrogen, which are essential for plant growth.
