Hog Waste & Some Interesting Uses For This

By Lianne Derocco


It is true that hog waste is foul smelling and dirty and annoys people but is also a fact that cannot be avoided in swine farming. Hog waste can also be of help to people however, rather than just a nuisance. Electricity can be produced using hog waste. The waste is contained and the methane gas produced by the waste is extracted and used as a source of fuel, producing electricity. Fertilizers can be made out of the waste, as well, which can help with the production of crops.

The soil needs nutrients in order to produce excellent crops, and these nutrients are coming from the fertilizers created from liquefied hog waste. Easy application and likewise the efficient spreading of fertilizer on the soil are needed, and this is realized after the swine manure is composted and liquefied. Recycling the hog waste nutrients in an environmentally friendly process is the objective, and the eventual fertilizers produced are used in vegetable crops. Biologically breaking down the organic matters in the hog waste is done with composting the hog waste.

There are scientific studies currently ongoing where hog waste and other kinds of waste excreted by animals are used to produce synthetic crude oil. Breaking down the carbohydrate materials in the liquefied hog waste is the process in this scientific project in the US, using heat and pressure, and thereby producing synthetic crude oil in the process. The future appears bright for these scientific research studies. Problems of what to do with hog waste might be solved if this waste can be used as a good, inexpensive source of fuel.

Hog waste also can be used as a binding material for asphalt, and there is also a process to do this. The process involves converting the hog waste into asphalt binding materials, and the ultimate results are binding materials that are less costly than petroleum-based binders. The cheaper the asphalt can be made, the cheaper the total cost of the road will be.

Of course, hog waste management is an extremely important part of the job for swine farmers. The hog waste lagoons should be fully contained because a leak can produce catastrophic effects and sources of pollutants to the groundwater. Hog waste lagoons and waste pits also should be treated and liquefied, so that there will be no solid build up on the bottom or crust at the top. Reducing these two problems also reduces problems such as foaming, odors and flies.

There is a natural agricultural waste product that helps hog producers reduce and solve these problems. This product is Agra Sphere or Lagoon Agra Sphere, and these use natural bacteria only that slowly eat away the solid waste formed. These are natural products that prevent sludge and crust formation and also eliminate foaming. Application of these products is easy because these are just tossed into the lagoons or waste pits and do not need mixing. These are also products that improve the nutrient value of the waste water.
