Waste oils pose a significant threat to human health and the environment. Waste oils have been known to cause extensive damage to all elements of the environment, including soil, vegetation, surface and ground water, air, etc.
At the same time, waste oil is a high calorific fuel, which can be used in Ukraine as a great alternative energy source to replace Russian gas. The calorific value of waste oil is 9550 kcal/l, which is higher than that of coal and fuel oils. Waste oils used as a secondary fuel should be pretreated to remove sediment and suspended solids.
Clinical studies have shown that exposure to burning crude oil fumes can affect the cardiovascular and the central nervous system, cause acute and chronic toxicity, occasionally fatal. Waste oil combustion products affect human health and increase the risk of lung cancer, throat cancer and lip cancer in men, and may cause lung cancer, colon cancer and breast cancer in women.
One of the most common technologies for energy recovery from untreated carbonaceous wastes is gasification in the absence of oxygen (pyrolysis). Gasification is a process of converting organic waste into combustible synthesis gas or syngas, which has a wide range of applications, and the main application is electricity generation. The synthesis gas produced from the pyrolysis can also be used as an intermediate in the organic synthesis producing methanol, ammonia, liquid fuels, etc.
