  • 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 ...

  • Project aims to produce fertilizer from wastes

    With the highest cattle density in northeastern Wisconsin and urban sprawl sprawling, Brown County has accelerated its investigation into how to handle growing amounts of dairy manure and industrial wastes spread on a diminishing land base.Applying waste on limited crop acreage has led to groundwater contamination issues and pollution problems of lower Green Bay.The solution lies in a value-added ...

  • Physico-Chemical P Removal from the Liquid Fraction of Pig Manure as an Intermediary Step in Manure Processing

    Abstract  Intensive animal farming has resulted in overproduction of manure in parts of the industrialized world. The localized excessive nutrient emission has detrimental effects on both ecology and economy. In response to European guidelines, Flanders (Belgium) has imposed obligations on the agricultural sector to process a portion of the produced animal manure. To achieve the stringent ...


  • Voluntary compost quality assurance based on the new Austrian compost decree

  • Composting infrastructure trends in the UK

    The European Union's Landfill Directive, which restricts landfilling of biodegradable waste, has made it necessary to develop alternative infrastructures to manage the organic fraction of the solid waste stream. In the United Kingdom, the Landfill Directive has created demand for composting facilities that take source separated organics (SSO), and for anaerobic digestion. Infrastructure also is ...

  • Composting

    Introduction Composting is a controlled biological process by which organic contaminants (e.g., PAHs) are converted by microorganisms (under aerobic and anaerobic conditions) to innocuous, stabilized byproducts. Typically, thermophilic conditions (54 to 65 °C) must be maintained to properly compost soil contaminated with hazardous organic contaminants. The increased temperatures result from heat ...

  • 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 ...

  • Cultivating energy crop production

    A NEW Farm Bill is moving through the Congressional legislative process. Along the way, commercial agriculture is debating the energy impacts of future corn and soybean production. The growth of corn-based ethanol and soybean-based biodiesel has created competition for the feed inputs into animal agriculture, namely corn and soybeans. While most of agriculture discusses energy production from ...

  • Latest Progress in Anaerobic Digestion

    Compared to countries like Germany and Denmark, the United States and Canada have a long way to go in creating the fundamental policy incentives and regulatory mandates that will encourage market development for anaerobic digestion (AD). Someone recently asked me how many years it would take to deploy AD systems on farms in North America that are large enough to economically use them. Given ...

  • Anaerobic Digestion at Dairy Farms

    The need to upgrade dairy waste management practices to overcome pollution problems is leading more farmers to seek solutions with anaerobic digestion technology. Two recent examples of this trend are underway at California sites. The Cal Poly Dairy is located adjacent to the California Polytechnic State University campus in San Luis Obispo. The dairy milks 180 cows with a total population of ...
