Some Exciting Uses Of Agricultural Waste From Hogs

By Lianne Derocco


Hog waste is dirty, with foul odor, and is an annoyance to people, but is a part of hog farming that cannot be avoided. However, hog waste can also be of help to people in some ways. Hog waste can produce electricity, and there is a process to do this. Hog waste is contained and methane gas is produced in the process, and thus is used to power the generators that produce the electricity. Hog waste also can be used as fertilizers, and thus can give savings to farm producers.

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.

Swine waste also can be produced into synthetic crude oil, using a process that is currently scientifically studied. Currently, this is a scientific research project that is still in its infancy according to scientists, but is also very promising. Crude oil produced from the process could be a fuel source and also ease the problems of swine producers regarding their hog waste, which would benefit most of us.

The swine waste in the farms can also be used as binder for asphalt, which is used to make roads. While a petroleum binder can be used, the binders made from hog waste are much less expensive, so this is a big plus. These are more eco-friendly binding materials that can reduce the overall costs associated with the paving of our roads and highways.

Management of hog waste is quite important because an error in management can cause serious complications. Waste lagoons and pits on the hog farm should be contained well because a small leak can lead to great havoc because this can pollute the groundwater in the local area. The treatment and efficient liquefying of the waste lagoons should be done in order to avoid the building up of solid waste matter, which causes excessive odors and foaming.

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.
