Frequently Asked Questions (FAQs)

1. Can you compost in metal bins?

To Build a Trash Can Compost Bin Even the metal cans can still be bent back into shape, but the lid might not lock as securely as you'd like. The hole saw bit cuts easily through either the plastic or metal with little resistance. To make, simply cut holes all around the can, including the bottom and the lid.

2. Is a compost bin worth it?

Conclusion. Composting is worth it for those who want to create their own nutrient-rich soil amendments for a yard, garden, or flower bed. Turning yard debris and kitchen waste into compost is an excellent way to save money, make use of otherwise discarded material, and prevent unneeded landfill waste.

3. What is the best material for a compost bin?

Fruit and vegetable trimmings, coffee grounds and filters, and eggshells are great items for the compost pile. Do not use animal products such as grease, fat or meat trimmings, or dairy products because they break down very slowly, attract rodents and other pests, and have an unpleasant odor when they decompose.

4. What is the best size for a compost bin?

General Composting Rules The composting pile should be at least 1 cubic yard (3' x 3' x 3'). Ideal size is a 3 to 5 foot square. Locate the composting pile on level, well-drained ground near a water source. Stay away from wooden fences and buildings.
