A compost pile can be referred to as many different things depending on the location and materials used. An outdoor compost pile can also be known as a compost heap, compost bin, or compost mound. For those who prefer an indoor composting system, they might use terms such as a worm bin, vermicomposting bin, or composting tower. A bokashi bucket or fermenting pail might also be considered a type of compost pile. Whatever you choose to call it, the important thing is that composting is a simple and effective way to reduce waste and create nutrient-rich soil amendments for your garden or plants.
