Plastic Waste Disposal: Source for Green Fuel

A latest technology has come into being that helps in converting this plastic waste disposal into a good source of green fuel. Not only does this technology helps save our environment from waste accumulation but also helps us save lot of money... Let us find out how...

Each day, we have lot of plastic waste disposal from our household. However, a latest technology has come into being that helps in converting this plastic waste disposal into a good source of green fuel. Not only does this technology helps save our environment from waste accumulation but also helps us save lot of money... Let us find out how...

Renewable Energy Investment is Viable

As the cost of recovering non-renewable fuel supplies increases, the viability of investment in other alternatives improves. Some of the most recent developments offer additional benefits while overcoming the problems that are associated with the first generation bio-fuels. The use of sugar cane, maize and palm oil as the basic raw material for first generation fuels is controversial because the production of these feed stocks displaces food production.

In the case of palm oil, there is yet another added problem that rain forests are being destroyed in order to create more oil plantations. In contrast to this, the use of maize has been enthusiastically embraced as it has being of enormous economic benefit to communities especially in the corn-belt in North America.

Other Renewable Fuel Options

There are second generation bio-fuels that do not compete directly with food production because they are able to use the whole plant and not just the seed. They can even utilise the waste from food production. So, for example, a grain is used for food and the rest of the plant to manufacture bio-fuel. Similarly palm seeds can be used to produce oils for food and the husks for bio-fuel.

Plastic Waste Disposal Producing Green Fuel

Meanwhile, several companies have begun operating plants that convert waste plastic to bio-fuel by using a similar process. Among them, Cynar which is head quartered in London but had its first plant operating in Portlaoise in Ireland, aims to install up to 30 plants throughout the British Isles. Similar plants are already in operation in Thailand and India.

The process of converting plastic waste into bio-fuel is quite simple. It is similar to how alcohol is made. If you heat plastic waste in non oxygen environment, it will melt, but will not burn. After it has melted, it will start boiling and eventually evaporate. You just need to put those vapours through a cooling pipe and when cooled the vapours will condense to a liquid and some of the vapours with shorter hydrocarbon lengths will remain as a gas. The exit of the cooling pipe is then going through a bubbler containing water to capture the last liquid forms of fuel and leave only gas that is then burned. If the cooling of the cooling tube is sufficient, then there will be no fuel in the bubbler, but if not, the water will capture all the remaining fuel that will float above the water and can be poured off the water. On the bottom of the cooling tube is a steel reservoir that collects all the liquid and it has a release valve on the bottom so that the liquid fuel can be poured out.

This method is doubly environmentally friendly as it will reduce the volume of plastic waste being disposed of in the landfill while producing green fuel without generating any green house gases.
