Aerated Manure Composting

Aerated Composting

Aerated static pile composting modifies the passive composting technique by using blowers to supply air to the composting feedstocks. This process does not involve turning and/or agitation of the piles after the initial mixture of feedstocks. Bulking agents are often used to help maintain the porosity structure of the piles, which aids in pile aeration. Electronic feedback controls are often used to monitor the pile temperature and control the operation of aerating blowers.

Separation Technologies for Capturing Nutrients from Manure

Exporting phosphorus and possibly nitrogen from larger livestock operations as well as regions of large livestock populations is often essential for protecting water quality. Solids (and nutrient) separation technologies are an option for concentrating nutrients for export. This webinar introduces three approaches to solids separation that are being applied in commercial settings. This presentation was originally broadcast on January 18, 2019.
