kierrätysöljy

Kierrätysöljy refers to used oil that has been collected and reprocessed for reuse. This category primarily includes used lubricating oils from vehicles and machinery, as well as other types of industrial oils. The collection and recycling of used oil are important for environmental protection and resource conservation.

Used oil contains valuable components that can be recovered and re-refined into new lubricating oils. The re-refining process involves removing contaminants such as dirt, water, metal particles, and additives. This is typically achieved through various stages of filtration, dehydration, and chemical or physical treatment. The resulting base oil can then be blended with new additives to produce high-quality lubricating oils that are comparable to virgin oils.

Alternatively, used oil can be processed for fuel purposes. Through a process called fuel blending, used oil is treated and mixed with other fuels to create an energy source for industrial furnaces, kilns, and other combustion applications. This method recovers the energy content of the oil, reducing the need for virgin fuel resources.

Proper disposal of used oil is crucial to prevent environmental pollution. When dumped into the ground or waterways, used oil can contaminate soil and water sources, posing a threat to ecosystems and human health. Therefore, many countries have established systems for collecting and recycling used oil, often through designated collection points or specialized companies. This practice not only minimizes environmental damage but also conserves finite petroleum resources by giving used oil a new life.
