Oils: Waste

Waste oil is oil that has been refined from any synthetic oil or crude oil that has been used and as a result of such usage, they have been contaminated by physical or chemical impurities. In simple terms, waste oil is exactly what its name implies- any synthetic or petroleum-based oil that has been used. When being used as per normal, impurities such as dirt, metal scrapings, water or chemicals are able to get mixed in with the oil so that in time the oil no longer performs well. This waste oil has to be eventually replaced with virgin or refined oil.


The Environmental Protection Agency defines waste oil as oil which mixed with hazardous waste that has to be disposed of---as opposed to "used oil," which can be recycled, refined or burned for energy. The following are examples of waste oil from the state of Maine: industrial lube oils, automotive crankcase and lubricating oils, including railroad and marine oils, metal working oils, and turbine-lubricating oils; industrial non-lube oils, including transmission-quenching oils, hydraulic and non-PCB (less than 5 parts per million) transformer oils; oil recovered from oil tank-cleaning operations and defalcating operations; and oil recovered from discharges to land or waters.


About Waste Oil

A form of waste oil is used oil which is liquid enough to be free-flowing and made to be lubricant. Keep in mind that unused oils, cleaning agents, solvents, or petroleum based products like kerosene or anti-freeze are not considered waste oils. According to the U.S. Environmental Protection Agency, waste oils have become contaminated as a result of usage. Contaminations are able to take place during storing, processing or handling and this can also include several contaminants like wood, dirt or metal shavings. Waste oils are able to be burned in boilers which are specially designed and intended strictly for that function. The result of waste oil burners can be used for heat or other purposes.


Recycling Waste Oil

Once oil is used, it is able to be collected, recycled and used repeatedly. About 380 million gallons of used oil are recycled each year. Recycled used oil in some circumstances can be used again for the same job or can take on a completely different task. For example, used motor oil is able to be re-refined and sold at the store in the form of motor oil or processed for furnace fuel oil. Rolling oils made of aluminum also can be filtered on site and used over again. Used oil can be recycled by reconditioning on site which consists of removing the impurities on site and using it again. Used oil can also be inserted into a petroleum refinery and involves the oil as a feedstock into either the front end of the process or the corker to produce gasoline and coke. Another way used oil can be recycled is by re-refining it, which basically stands for removing impurities from the oil so that it can be used as a base stock for new lubricating oil. Used oil can also be processed and burned for energy recovery. This means the water and other oil particles is removed in order for the oil to be burned as fuel, to generate heat or to generate power industrial operations.


Companies dealing with Waste Oil

There are different types of companies which deal with used oil. The first type being generator companies who handle oil for industrial and commercial operations. The second are aggregation points and collection centers which collects small amounts of used oil until enough has been collected to ship it elsewhere for recycling. The third type of company are transporters which pick up oil from various points and transports them to burners, re-refiners or processors. There are also re-refiners which remove or blend the impurities from used oil so that it can be burned for reuse or the recovery of energy. The fifth type is burners who burn used oil for energy recovery in various vicinities. The final type is marketers who handle shipments related to waste oil to be burned as fuel in regulated services.
