(200e) Nutrient Pollution Prevention By Implementing Nutrient Recovery Technologies in Livestock Facilities
On the other hand, a decision-making tool for the design and selection of optimal nutrient recovery and valorization technologies has been developed. This tool evaluates different nutrient recovery technologies based on a set of parameters to describe the studied facilities: the operational parameters from each livestock installation (size and current manure collection equipment), product quality, capital investment available to implement the nutrient recovery system, and the targeted environmental footprint reduction to be achieved. Considering these input parameters, the tool determines the most appropriate technology for the evaluated facility, as well as a preliminary design of the equipment involved in the selected technology.
The developed tool is applied to a realistic case study of cattle facilities in the U.S., by considering the location of the livestock farms and their size. Therefore, optimal phosphorus and nitrogen recovery technologies are determined for different scenarios involving diverse investment budgets. In addition, current and potential U.S. government incentives for nutrient pollution prevention and product valorization are taken into consideration.
Working with facility location information, such as the pollution level of the surrounding soils, the presence of water bodies susceptible of being polluted by nutrient run-off, and the availability and location of potential agricultural product customers provide supplementary data about the technology implementation, which can be included in the decision-making strategy. Therefore, this information allows adding new elements about the context of the studied facility to the decision-making procedure, granting that the reached solution is adequate to the livestock facility and its particular setting.
