Recycling used oil is as beneficial to the environment as with recycling general waste. Like empty plastic bottles, tin cans, and scrap metals, used oil can be reclaimed and reused. As a result, less amount of hazardous waste is disposed of.
Recycling can Start with You
Among community members, vehicle owners count as the major source of used oil. Every time their cars change oil, it gives them the chance to recycle it. Bringing it to oil recycling facilities is a start and vital aspect of waste recycling.
A small amount of used oil can be brought to local facilities, along with oily rags, plastic containers, and oil filters. These can be found at landfill and waste transfer station and at works depot. Used oil can be placed in an empty oil container where collectors will get it for storage and pre-treatment called dewatering.
According to Waste Petroleum Combustion Limited, during this process, collected waste oil is transferred into large settling tanks to separate oil and water.
Further Recycling Treatments
There are three more steps for further recycling of used oil, namely
- filtering and demineralisation – the processes for removing solid, inorganic materials and additives present in the used oil for a cleaner burner fuel.
- propane and de-asphalting – where heavier bituminous fractions are removed to produce re-refined base oil.
- and distillation – the physical components of the lubricating oil are separated by boiling range. The re-refined base oil produced through this process can be used as a lubricant or hydraulic oil. It is similar to the core processes used by facilities producing virgin oil.
Recycled oil can be used as industrial burner oil, hydraulic oil, re-refined base oil, mould oil, and additive in manufactured products. The 269 million litres recycled in 2008-2009 tells how the country is becoming better at recycling used oil. Thanks to used oil recycling programs from the government, and the incentives it offers to encourage more to get into recycling.
