The world's annual consumption of oils is growing every year, in 2015 it amounted to about 45 million tons. Every year the issue of environmental pollution by oil products is becoming more acute. This problem is hotly debated, and various ways are proposed to solve them.
However, it is often not taken seriously that conventional engine oils and greases are not recycled after use. They are pumped into water bodies and soil. And this causes irreparable harm not only to the environment but also to health. Only about 50% (ie about 22 million tons) of used oil is systematically collected all over the world. The rest is uncontrollably drained, burned, or used by other incorrect methods.
The idea to recycle oil arose at the end of the 20th century when purchasing a car became available to a wide segment of the population. However, it received an incarnation relatively recently. There are many ways to process oils. The main ones are:
- Recycling. With this method, the oil is purified from water and impurities. The resulting substance is further used as fuel. With more complex processing, a new product is obtained that is indistinguishable from that obtained from crude oil. And this is the most economical and environmentally friendly way.
- Cleaning. This is the processing of oil using sedimentation tanks, filters, centrifuges, etc. This procedure applies mainly to machine, turbine, industrial and all types of transformer oil.
- Regeneration. This is a more complex process by which used oil is restored to the performance of new oil.
Unfortunately, a very small percentage of used oils are processed in Ukraine. According to some estimates, it ranges from 3% to 20%. This sector of industry leaves room for development. Science does not stand still. And today there are many ways available to use recycled oil, thereby preserving and protecting not only the environment but also the population.
