Huge amounts of animal waste containing urine and feces accumulate in livestock farms. Disposal of the waste creates a huge problem. It is a hazard to the environment creating harmful gases that contribute to the greenhouse effects that are causing global warming.
The scientific community spends quite a lot of research to discover methods of resolving the animal waste disposal. They are looking for ways to turn this waste into something useful.
The following video highlights a useful idea for a pig manure extract, petroleum. Yes, surprisingly one of the components contained in the animal waste is a type of petroleum. Which, is also a key ingredient of an important product for our road infrastructure, asphalt.
The success of using animal waste for a useful and needed product will certainly be monitored with great interest. Of course, with any new product, it will have to be thoroughly tested to verify the expected useful life. This material is obviously much cheaper than the current petroleum which is extracted from oil.
Time will tell as the development process continues to prove how well the asphalt made from pig waste will hold up to intense road traffic, weather and other abuse.

Between our world and the outside universe is a layer of gases. This layer, our atmosphere, is what sustains human life on planet earth. There is currently much concern about climate change coming about from car exhaust and cow farts, among other things.
Trapped under this layer is Oxygen, a necessary component for humans.The atmosphere also protects us by blocking harmful intruding emissions from the sun. The prevailing climate is determined in large part by this layer of gases.
Heat coming from the sun radiates back from the earth’s surface. Based upon the combination of gases that makeup the atmosphere, some of the radiation of heat from the earth will be blocked. This greenhouse effect will raise (or lower) the temperature of the earth’s atmosphere, which is necessary to provide a temperature and climate that will sustain our life on earth.
Two of the gases that contribute to heat buildup, called the “greenhouse effect”, is Methane and Carbon Dioxide. Here is where cows and cars come into play. Cars produce massive amounts of Carbon Dioxide (CO2) in the exhaust from burning fuel. This CO2 becomes part of the atmosphere, which will impact the makeup of the atmosphere by causing more heat to be blocked.
Cows create some CO2, but of more importance, methane gas in cow farts. The methane gas is 20 times more powerful at blocking heat than CO2. Thus, the impact to global warming is much higher with methane. As the buildup of gases increases with earth’s population demanding more cars and meat producing stock, an unnatural climate change is taking place.
Climate change will have an impact on weather patterns around the world. Where it rains the most, where it is dry, where major storms tend to be active and more. Impact from climate change is being studied to learn what we can do (and not do) that will lessen the harmful effects to our atmosphere.
The below video provides some insight into the impact of cow methane production impacts climate change.
