In-vessel composting


In-vessel composting

In-vessel composting is an industrial form of composting biodegradable waste that occurs in enclosed reactors. These generally consist of metal tanks or concrete bunkers in which air flow and temperature can be controlled. In-vessel composting can also refer to aerated static pile composting with the addition of removable covers that enclose the piles.

Offensive odours are caused by excess nitrogen or moisture. This may be controlled with a higher carbon to nitrogen ratio or increased aeration by ventilation, mixing, or by using a coarser grade of carbon material. Insects may be controlled by keeping the bin enclosed with the minimum size vents necessary for adequate air exchange. Insects outside the bin enter through the vents and tend to stay inside where the food is. A relatively dry layer of carbon material on top of the compost filters odors and, given adequate ventilation, maintains a moisture gradient that helps keep insects inside where the moisture is.
