Manure Covers and Biofilters for Managing Odor and Air Emissions

Animal Manure Management January 27, 2014|Print

Covers and biofilters are two techniques that can be used to help manage odors and other airborne emissions from animal feeding operations and manure storage units. Watch these two videos to learn about covers and biofilters, how they work, and related costs and benefits of different methods to reduce airborne emissions. Links to additional techniques and information are given below.

Manure Storage Covers for Reducing Odor Emissions

Visit the Feedlot Air Emissions Treatment Cost Calculator website to download a spreadsheet to help calculate costs and benefits of installing technologies to treat odors and gas emissions from animal feeding operations. A good tool to assess current management practices and their impact on air emissions, including odor, is to use the National Air Quality Site Assessment Tool (NAQSAT). Manure Storage Covers includes many more resources on this topic.

Biofilters for Reducing Odors and Gas Emissions

More is available on Biofilters. There are several methods that can be used to manage odor and other airborne emissions from animal feeding operations. Additional techniques and management information include:
