Composting organic waste is one realistic way to reduce the amount of waste that is thrown into landfills. Because of this, the city of San Francisco has a mandatory composting program. However, anyone can compost at home by placing organic wastes into a pile and allowing them to decompose into nutrient rich, black soil. To keep your compost pile neat and to speed the process of composting, you can build a compost tumbler bin.
Pull on work gloves and safety goggles before starting your project.
Attach 1/2-inch drill bit to your drill. Drill holes throughout your trash can's top, sides and bottom, spacing each hole approximately 6 inches apart.
Place the trash can on top of the concrete blocks to facilitate air circulation throughout your compost bin.
Layer compost in the bin by alternating nitrogen-rich green organic compost, and carbon-rich brown organic materials. Add slightly more brown material to your compost pile to achieve a good ratio of brown to green material.
Stir your compost once a week by taking the can off of the blocks and rolling it around on its side to help the compost break down faster.
