Organic Composting Types
Aerobic Composting - This means to compost with air. High
nitrogen waste (like grass clippings or other green material) will
grow bacteria that will create high temperatures (up to 160
degrees). Organic waste will break down quickly and is not prone to
smell. This type of composting is high maintenance, since it will
need to be turned every couple days to keep air in the system and
your temperatures up. It is also likely to require accurate moisture
monitoring. This type of compost is good for large volumes of
compost.
Anaerobic Composting - This is
composting without air. Anaerobic composting is low maintenance
since you simply throw it in a pile and wait a couple years. If you
just stack your debris in a pile it will generally compact to the
point where there is no available air for beneficial organisms to
live. Instead you will get a very slow working bacteria
growing that does not require air. Your compost may take years to
break down (this is what happens when you throw your food waste in
the garbage that goes to the landfill). Anaerobic composts create
the awful smell most people associate with composting. The bacteria
break down the organic materials into harmful compounds like ammonia
and methane.
Vermicomposting - This is most beneficial for
composting food waste. Along with red worms, this includes
composting with bacteria, fungi, insects, and other bugs. Some of
these guests break down the organic materials for the others to eat.
Red worms eat the bacteria, fungi, and the food waste, and then
deposit their castings. Oxygen and moisture are required to keep
this compost healthy. This is medium maintenance compost since you
need to feed your red worms and monitor the conditions.
