2007 Chemical recycling of plastic wastes made from polyethylene LDPE and HDPE and polypropylene PP. Compared to the above methods gasification produces syngas as the main product while biochar is the by-product with less yield. However to the best of our knowledge a comprehensive review of waste oils pyrolysis especially advanced pyrolysis is still lacking.

Wang et al. A recent trend however is to reduce the vacuum degree and its complication up to the realization of the so-called laser coatings Simoni et al 2021. In our previous research after the direct pyrolysis of waste vegetable oil it was found that there are a large number of oxygenates in the pyrolysis oil mainly long-chain fatty acids and carbonyl compounds Wang et al.
