Special Issue Information

Dear Colleagues,

Most livestock production systems are complex systems that integrate both plant and animal production to harvest animal protein effectively, including the use of livestock manure as a source of nutrients for crops. However, the recent increasing demand for animal protein for human consumption has resulted in livestock production intensification through confined animal feeding operations (CAFOs). These CAFOs are the fastest growing form of industrial animal production due to its high efficiency in producing meat. However, manure management for CAFOs becomes a significant environmental issue because of the generation of high amounts of nitrogen and phosphorus in manure and the difficulty of applying manure to crop land far away from the CAFOs due to high transportation costs. The excessive application of nutrients to crop and pasture lands near CAFOs can contribute to water quality impairment via soil runoff and leaching. In addition, the overapplication of animal manure can spread pathogens, release hormones and other pharmaceutically active compounds, and emit ammonia, greenhouse gases, and odorous compounds. For this Special Issue, we seek innovative technologies for manure management that maximize the recycling of nutrients, convert livestock waste into valuable byproducts for reuse or bioenergy, and reduce the environmental footprint of livestock production while promoting sustainable environments. Potential topics covered in this Special Issue include, but are not limited to:

  • Development of manure and livestock waste processing, treatment, and value-added technologies to reduce pollutant emission and promote circular economies of manure byproducts and sustainable food systems;
  • Production of energy and valorization of manure byproducts using thermal- and/or bio-based technologies;
  • Innovative applications of manure-derived products for improving soil, water, and air quality;
  • Manure treatment systems that yield additional benefits such as odor and pathogen reduction, GHG reduction, and generation of water for on-farm reuse and provide ecosystem benefits such as the protection and restoration of water quality and the generation of water quality credits.

Phosphorus (P) is essential for life and has a fundamental role in industry and the world food production system. The present work describes different technologies adopted for what is called the second-generation P recovery framework, that encompass the P obtained from residues and wastes. The second-generation P has a high potential to substitute the first-generation P comprising that originally mined from rock phosphates for agricultural production. Several physical, chemical, and biological processes are available for use in second-generation P recovery. They include both concentrating and recovery technologies: (1) chemical extraction using magnesium and calcium precipitating compounds yielding struvite, newberyite and calcium phosphates; (2) thermal treatments like combustion, hydrothermal carbonization, and pyrolysis; (3) nanofiltration and ion exchange methods; (4) electrochemical processes; and (5) biological processes such as composting, algae uptake, and phosphate accumulating microorganisms (PAOs). However, the best technology to use depends on the characteristic of the waste, the purpose of the process, the cost, and the availability of land. The exhaustion of deposits (economic problem) and the accumulation of P (environmental problem) are the main drivers to incentivize the P’s recovery from various wastes. Besides promoting the resource’s safety, the recovery of P introduces the residues as raw materials, closing the productive systems loop and reducing their environmental damage. Full article
