Some Exciting Uses Of Agricultural Waste From Hogs

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.

There is also a process that can make hog waste produced as binding materials for asphalt. Binding materials are ultimately produced from this process, and the materials are less costly compared to petroleum based binders. The petroleum-based binder materials in asphalt are quite expensive, so using hog waste is a cheaper alternative that can lower the overall costs associated with road construction.

Some mismanagement in the farms' waste systems can result in serious complications and this shows the importance of efficient hog waste management. A small leak in the lagoons can be a source of pollution to the groundwater, for example. Odors and flies also increase with improper waste management, such as allowing a heavy sludge layer to form on the bottom of the waste pit or lagoon. Top-level crusting and foaming are other common problems with which farmers must contend.

These problems can be solved however, with natural agricultural waste products available that can help producers with their problems. Products that have natural bacteria that eat away the solid waste formations are these products, and these include products such as Agra Sphere and Lagoon Agra Sphere. Prevention of sludge and crust formations and also eliminating foam formation are objectives, and these are the products that can eat away at solid waste. In addition to liquefying waste, the bacteria in these agricultural waste products also improves the value of the nutrients in the waste, which improves the quality for fertilizers.
