The Suståne compost facility is located central to family owned and operated turkey farms on a 40-acre site in southern Minnesota. This is the first and only one of its kind. It is a US Environmental Protection Agency licensed compost facility for the aerobic composting of turkey litter.

The base material for many Suståne fertilizers is a high quality, nutrient rich composted turkey litter. During the Suståne aerobic, thermophilic composting process, raw volatile organic matter is biologically converted over a twenty six weeks into nutrient rich stabilized organic matter called humus. Three tons of turkey litter is required to produce one finished ton of Suståne.

Carbon is the building block of all life forms Carbon + Nitrogen + Water + Oxygen. These are the basic components of Suståne compost.

The turkey litter is composted for 26 weeks until the material is fully stabilized. During this time the material is turned (aerated) twice weekly to ensure the microbial populations in the rows have access to sufficient amounts of oxygen.

Water is added to the rows to ensure the proper moisture content is maintained during the composting process.

Temperatures are monitored weekly to verify that there is sufficient microbial activity for proper decomposition and pathogen destruction.
