Pyrolysis of plastic and plastic in this case, if it is a solid waste disposal – it incineration of plastic waste containing hydrocarbons, oxygen-free environment at a temperature of about 600 C. During this process, the solids are converted into a hot gas, which can be used to generate heat energy and a liquid – oil.
From the liquid obtained by the pyrolysis of plastics at this time learned to make synthetic fuels which after purification can be used in internal combustion engines. However, the purification technology in this case is so complex that some of whatever the profitability of this method is not out of the question.
In this idea, in fact, nothing new there is simply no. In Germany, before the beginning of World War II, the pyrolysis method is widely used to produce fuel: Nazi tanks entered the USSR on fuel oil, which was obtained from coal by the Fischer-Tropsch technology. Of course, since the fuel quality requirements have undergone significant changes.
Pyrolysis of plastic destroyed approximately 99.9% of the harmful substances have been added to polymers in the production. Remaining after pyrolysis and briquette ash can be used as heating oil. Therefore, plastic waste pyrolysis are perfectly safe.
However, this method is not deprived of drawbacks, the main of which is that in the pyrolysis process is formed a plurality of harmful chemicals. In order that they do not fall into the atmosphere necessary to use fairly complicated filter systems.
This is a fairly expensive equipment, which is not the best way affects the profitability of the method of recycling plastic. In addition, since the amount of plastics consumption is growing every day, the market is in deficit of polymer raw materials.
It is for this reason that the most appropriate method of processing plastic Russia is a mechanical recycling – recycling of plastics. This method is good in that it does not require the use of expensive special equipment, and therefore can be implemented anywhere. Any waste treatment plant can be equipped with facilities for recycling plastic.
Recycling plastic.
Recycling of plastic waste includes the following milestones:
-Collect Plastic waste
Collate waste (in color, quality, degree of contamination)
-Pressovanie Waste
-processing Waste, which includes cutting the raw material by washing, drying and manufacturing process regrind
-Production Of new products from recycled plastic
-Application Recycled plastic
Recycled plastic can be used for various purposes. Thus, it is used for the manufacture of synthetic yarns, which can then be used to make garments, carpets, films, and other articles. Approximately two-thirds of secondary European plastics used for the production of polyester, are used as insulation sports clothing, sleeping bags and filler for soft toys.
Also recycled plastic can be produced and packaging. From plastic waste mixed with mineral fillers (ash, sand) produced polymer concrete, which is very strong and durable material, which has many uses in the construction sector. In short, places where you can use an incredible amount of recycled plastic.
