Season matters when sampling streams for swine CAFO waste pollution impacts
Concentrated (or confined) animal feed operations (CAFOs) are the principal means of livestock production in the United States, and such facilities pollute nearby waterways because of their waste management practices; CAFO waste is pumped from the confinement structure into a cesspit and sprayed on a field. Stocking Head Creek is located in eastern North Carolina, a state with >9,000,000 ...

Anodic oxidation of slaughterhouse wastewater on boron-doped diamond: process variables effect
A non-sacrificial boron-doped diamond electrode was prepared in the laboratory and used as a novel anode for electrochemical oxidation of poultry slaughterhouse wastewater. This wastewater poses environmental threats as it is characterized by a high content of recalcitrant organics. The influence of several process variables, applied current density, initial pH, supporting electrolyte nature, ...

Chicken Manure Management, Recycling, and Composting
Chicken Manure Fertilizer Manufacturing Process If you have chickens, you will have manure. Fortunately, chicken manure is among the most prized of manures. Fresh chicken manure is considered a “hot” manure, which is unsuitable for immediate use. Chicken manure needs to be composted and aged at least two to three months before you add it to your garden. If you don’t wait that ...

Animal Manure or Sludge Organic Fertilizer Production
Introduction of Animal Manure or Sludge Organic Fertilizer Production Line Organic fertilizer production line is designed for producing organic fertilizer from animal manure or sludge, without any chemical ingredients. As chickens, pigs have a poor digestion, can only consume 25% of the nutrients, so other 75% of feed nutrients with feces discharge can be produced to the dry nitrogen, ...

Pet Cremation as Business
As a nation of animal lovers we want to look after our pets as well as we possibly can and treat them with respect for the whole of their lifetime. When our pet dies we want to know that this respectful attitude also extends to the disposal of their remains. Some owners will opt to bury a much-loved pet in their garden, but may find that this is prohibited by their Local Authority or is only ...

New study finds recycled phosphorus could fertilize 100 percent of U.S. corn
The world has a problem. A phosphorus problem. Needed to fertilize crops, the bulk of phosphorus comes from nonrenewable phosphate rock. While China mines the most — producing almost half the world’s phosphorus — Morocco alone controls three-fourths of global phosphate rock reserves. Year by year those global reserves dwindle, leaving phosphate rock that’s ever lower in ...

Groundwater nitrate and chloride trends in an agriculture-intensive area in southern Alberta, Canada
The potential effect of manure management from livestock production on groundwater quality is an issue of concern. Groundwater sampling from a regional transect in southern Alberta, Canada, was conducted to determine changes in groundwater quality with time. The study area has extensive irrigation and a high density of confined feeding operations. Nitrate-N (NO3−-N) and chloride (Cl−) ...

Transition of fertilizer application and agricultural pollution loads: a case study in the Nhue-Day River basin
Rapid socio-economic development in suburban areas of developing countries has induced changes in agricultural waste and nutrient management, resulting in water pollution. The study aimed at estimating agricultural nutrient cycles and their contribution to the water environment. A material flow model of nitrogen (N) and phosphorus (P) was developed focusing on agricultural activities from ...

The market incentives that are keeping trees standing in Brazil
And now for some good news: It looks like some market-driven agreements around beef production in Brazil may be slowing deforestation in the country’s rainforests. That’s the finding reported by Holly Gibbs, an assistant professor of geography and environmental studies at University of Wisconsin–Madison, and a team of researchers in a paper published recently in Conservation ...

The potential of ultrasonic membrane anaerobic systems in treating slaughterhouse wastewater
Direct discharge of slaughterhouse wastewater causes serious environmental pollution due to its high chemical oxygen demand (COD), total suspended solids (TSS) and biochemical oxygen demand. In this study, an ultrasonic-assisted membrane anaerobic system was used as a novel method for treating slaughterhouse wastewater. Six steady states were achieved, using concentrations of 7,800–13,620 ...

Process parameters analysis for the vermicomposting of shredded paper using Pheretimoid Spp.
This study was to assess the effect of new species of earthworms, Pheretimoid Spp., on vermicomposting and compare the quality of vermicompost against compost produced from the same mix ratio of shredded office paper (SOP) together with grass clippings (GC) and cow manure (CM). Two composting experiments were setup in rotary drum composters namely: 1) composting of SOP, GC and CM followed by ...

Removal of 2-methylisoborneol from aqueous solution by cattle manure compost (CMC) derived activated carbons
The objective of this study is the synthesis of activated carbon derived from cattle manure compost (CMC) causing environmental problems using zinc chloride (ZnCl2) activation and to examine the suitability and performance of the prepared activated carbon (PAC) in removing 2-methylisoborneol (2-MIB) from aqueous solution. The influence of ZnCl2/CMC ratios and outgassing from the PACs on the ...
