Used oil" is a precise regulatory term. "Waste oil" is a more generic term for oil that has been contaminated with substances that may or may not be hazardous. [1] Any oil contaminated with hazardous waste may itself be a hazardous waste, and if so, must be managed subject to hazardous waste management standards.
When vegetable oil is used directly as a fuel, in either modified or unmodified equipment, it is referred to as straight vegetable oil (SVO) or pure plant oil (PPO). Conventional diesel engines can be modified to help ensure that the viscosity of the vegetable oil is low enough to allow proper atomization of the fuel.
Waste oil in the form of motor oil. Waste oil is oil containing not only breakdown products but also impurities from use. Some examples of waste oil are used oils such as hydraulic oil, transmission oil, brake fluids, motor oil, crankcase oil, gear box oil and synthetic oil. [53] Many of the same problems associated with natural petroleum exist ...
Used oil re-refining is the process of restoring used oil to new oil by removing chemical impurities, heavy metals and dirt. [2] Used industrial and automotive oil is recycled at re-refineries. The used oil is first tested to determine suitability for re-refining, after which it is dehydrated and the water distillate is treated before being ...
The burn barrel is a somewhat more controlled form of private waste incineration, containing the burning material inside a metal barrel, with a metal grating over the exhaust. The barrel prevents the spread of burning material in windy conditions, and as the combustibles are reduced they can only settle down into the barrel.
The open burning of waste is a disposal method of waste or garbage. It is a disposal method used globally, but often used in low and middle-income countries that lack adequate waste disposal infrastructure. Numerous governments and institutions have identified the open burning of waste as a major contributor to greenhouse gas emissions. It also ...
Indonesia used to be a net oil exporter. Oil is a major sector in the Indonesian economy. During the 1980s, Indonesia was a significant oil-exporting country. Since 2000, domestic consumption has continued to rise while production has been falling, so in recent years Indonesia has begun importing increasing amounts of oil.
Lean-burn refers to the burning of fuel with an excess of air in an internal combustion engine. In lean-burn engines the air–fuel ratio may be as lean as 65:1 (by mass). The air / fuel ratio needed to stoichiometrically combust gasoline, by contrast, is 14.64:1. The excess of air in a lean-burn engine emits far less hydrocarbons.
