Unlocking the Potential: Insects as Key Players in Future Food and Feed Systems
Insect Cultivation: Transforming Waste into Valuable Resources for a Sustainable Circular Economy Insects offer a fascinating opportunity to transform otherwise unused matter into valuable materials, such as proteins and fats. By doing so, they play a vital role in a circular economy, upcycling waste into resources that hold significant value for the feed, food, and agricultural ...

Biobased Economy opportunities for North-Netherlands
The three Northern provinces of the Netherlands could join forces to become a major producer and supplier of renewable resources for the regional production of ‘green’ chemicals, plastics and animal feed. This is one of the conclusions from research carried out by Wageningen University & Research, Greenlincs and the University of Groningen. Close collaboration with the German ...

CAFO Manure Treatment-Struvite Removal and Struvite Prevention
CAFOs (Confined Animal Feeding Operations) face struvite in their manure holding ponds and manure lagoons, as well as their recirculation systems. On a dairy farm in Neb. that operated with 15,000 milking cows, they were generating 500,000 gal per day of wastewater laden with manure. Over the summer, they noticed a reduction in their pumping capacity because the first lagoon was filling faster ...

Regulating the land application of manure from animal production facilities in the USA
Water pollution from the land application of manure has been cited as an issue that needs to be addressed. Judicial challenges have forced the US Environmental Protection Agency (EPA) to adopt additional controls governing concentrated animal feeding operations (CAFOs). State agencies have also been directed to do more to minimize the risk of pollution from animal production. In developing ...

Managing waste from confined animal feeding operations in the United States: the need for sanitary reform
Confined food-animal operations in the United States produce more than 40 times the amount of waste than human biosolids generated from US wastewater treatment plants. Unlike biosolids, which must meet regulatory standards for pathogen levels, vector attraction reduction and metal content, no treatment is required of waste from animal agriculture. This omission is of concern based on dramatic ...

Ammonia volatilization from Urea-based fertilizers applied to tall fescue pastures in Georgia, USA
The use of urea fertilizers in grasslands is likely to increase in areas with concentrated animal feeding operations as restrictions on manure applications are implemented. Concerns have been raised about the economic and environmental impacts of NH3 loss from these urea fertilizers. This study evaluated NH3 losses from Nitamin (a urea polymer), urea–NH4NO3 (UAN), and granular urea applied to ...

Transport of lincomycin to surface and ground water from manure-amended cropland
Livestock manure containing antimicrobials becomes a possible source of these compounds to surface and ground waters when applied to cropland as a nutrient source. The potential for transport of the veterinary antimicrobial lincomycin to surface waters via surface runoff and to leach to ground water was assessed by monitoring manure-amended soil, simulated rainfall runoff, snowmelt runoff, and ...

Formation and emissions of ammonia and greenhouse gases from stored and composted solid animal manure
Beside other branches of industry, agriculture is an important source of methane (CH4) and nitrous oxide (N2O) emissions and the most important source of ammonia (NH3). In spite of several investigations concerning ammonia and greenhouse gas emissions during storage and composting of liquid and solid animal manure, the real extent of these emissions is still unknown. This is mainly because of the ...
