Inclusion of the Environment Bottom Line in Waste to Worth: The Interaction Between Economics, Environmental effects, and Farm Productivity in Assessment of Manure Management Technology and Policy

Proceedings Home | W2W Home waste to worth 2017 logo

Purpose

In a global context, the pork industry constitutes a huge economic sector but many producers operate on very thin margins. In addition, pork is one of the largest and most important agricultural industries in North Carolina and the United States but faces a number of challenges in regards to waste management and environmental impacts.…

The poultry industry has enjoyed a long run of technological and scientific advancements that have led to improvements in quality and efficiency.  To ensure its hard-won prosperity continues into the future, the industry has rightly shifted its focus to sustainability. …

Valorization of Manure Treatment for Poultry and Swine Operators


Proceedings Home W2W Home w2w17 logo

Purpose 

Current practices for nutrient removal or recovery of phosphorus focus on chemical precipitation technologies, where the recovered products are low-grade, slow-release, low-value land applied fertilizers. Three significant deficiencies re this process – the cost of recovery is greater than the market value as commercial P fertilizer; the land application of such materials perpetuates the current cycle of pollutant nutrient “leakage” into surface waters; and the approach is not viable to address non-point source pollution or the legacy P present in impaired water bodies.…

Purpose 

To provide information about commonly-found manure management systems and approaches in North Carolina and the Coastal Plains, and discuss opportunities for technological innovation in the areas of manure management and nutrient recovery/utilization. Hear from a diverse panel of researchers, animal agriculture producers, and agency representatives who will provide background on the environmental conditions of the region and discuss specific technical considerations for innovative research and development.…

Closing Abandoned Livestock Lagoons Effectively to Utilize Nutrients and Avoid Environmental Problems


Proceedings Home W2W Home w2w17 logo

Purpose 

In Nebraska alone, nearly 400 earthen manure storage structures are in operation; approximately four dozen requests to cease operation of permitted lagoons were received by the Nebraska Department of Environmental Quality in the prior decade with many more non-permitted storage structures being in need of proper closure.…

Recovery of Ammonia and Production of High-Grade Phosphates from Digester Effluents


Proceedings Home | W2W Home w2w17

 

Purpose

Conservation and recovery of nitrogen and phosphorus from animal wastes and municipal effluents are important because of economic and environmental reasons. This paper presents a novel technology for separation and recovery of ammonia and phosphorus from liquid swine manure, which has significant amount of nutrients but also contains relatively high moisture content.…
