Interesting Uses For Hog Waste

By Lianne Derocco


Hog waste is part of hog production and is an unavoidable outcome in this process, although it is dirty and foul smelling and is a source of annoyance to people. Hog waste can be a source of air pollution in the area and also a source of toxins that can pollute the environment, but hog waste can also help people in some ways. For instance, generators that produce electricity are powered by methane gas produced from the contained hog waste. Many fertilizers that enrich soil for crops also are created using hog waste.

Hog waste used as fertilizers are liquefied and this liquid supplies the crops with much needed nutrients. Swine manure is composted and liquefied, making it easy to be applied and spread on the soil efficiently. This is often used in vegetable crops and is a good way to recycle hog waste nutrients in an environment friendly way. Composting is done first because this is the process that biologically breaks down organic matters found in the hog waste.

Hog waste also can produce synthetic crude oil, like waste excreted by other animals, and there is an ongoing scientific study to do this. In the U.S., there is a research study that breaks down the carbohydrate materials in the liquefied waste and turns these into synthetic crude oil, using heat and pressure. Scientists claim that the scientific project is still in its infancy stage but is with a bright future. The synthetic crude oil produced can be a good source of fuel while also help solve the problems of hog producers with their hog wastes.

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.

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.

A natural agricultural waste product is available that can help swine producers reduce and even eliminate these concerns. Agra Sphere and Lagoon Agra Sphere are these products, and natural bacteria are used to eat away the solid waste formation in the lagoons. These are products that will prevent sludge and crust forming in the lagoons and also the foaming. Product application is easy because the products are just tossed in and mixing isn't required. These are also the natural products that help improve the nutrient value of the waste so it becomes a better fertilizer.
