Composting Series Pt. 2: Different Methods

While composting can be used as a blanket term, there are several methods that are best for certain environments. For example, an at-home compost bin and one that serves an entire community are not going to look or function the same.

There are five main traits that must be “controlled” in any kind of composting system, similar to a science experiment. These include the following:

1. Feedstock and nutrient balance

As mentioned in the previous blog post (link), composing requires a balance of green and brown organic materials, which ensures equilibrium between carbon and nitrogen rich substances.

2. Particle size

Grinding, clipping, and shredding compost materials increases the usable surface area on which microorganisms can feed, which helps to produce a more homogeneous mixture. However, if the particles are too small, this can prevent air from flowing freely through the pile.
