We propose a new concept using an industrial by-product waste material that could satisfy the livestock industry needs in odor control and abatement, at an affordable cost. The objective is to conduct a feasibility study of this low-cost, economical alternative for odor control on farms, that will allow virtually any liquid manure storage system to be covered by mechanical methods. APPROACH: Once the feasibility of the material is established, we will proceed to a full field experiment trial with multiple replications under Phase II of the project. NON-TECHNICAL SUMMARY: Most livestock manure storage structures are open-air earthen and formed structures or under-slat structures for liquid manure storage. This manure storage system allows for seasonal manure application on harvested or small growing crops, but has the disadvantage of exposing odors or gaseous emissions to production workers, neighbors, and the environment. Previous research has discovered that permeable and impermeable covers can be effective in controlling and abating livestock manure storage odors. Research has also shown that finding a cover that is effective at controlling odors, is low-cost, and easy to install and maintain, with a practical useful life is not available today. Offensive manure storage structure odors are a continual problem for the Livestock industry. The product described in this proposal will serve as a low-cost, economical alternative to the many solutions previously offered, and has the potential to take odor control options to a new level while drastically reducing the costs. The features of this industrial by-product will allow for virtually any liquid manure storage system to be covered by mechanical methods. Successful odor control will improve community relations, lower production cost-of-gain, and provide a higher quality ambient air for worker safety.
