Sustainable hydrocarbons are one of the main methods decreasing use fossil fuels and derivatives, contributing to mitigation environmental impacts greenhouse gas emissions. Circular economic concepts focus on reusing waste by converting it into new products, which then input again industrial production lines, thus necessity fossils. Polypropylene-based plastic can be depolymerized smaller chemical chains, producing a liquid phase rich in hydrocarbons. In same way, triacylglycerol-based biomasses also converted renewable Our research studied co-processing polypropylene (PP) cottonseed oil dreg (BASOs) from biodiesel industry using micropyrolysis system at 550 °C, previously validated predict scale-up process. PP showed alkanes alkenes, while BASOs produced carboxylic acids addition products. The were observed conversion yields, reaching highest values pyrolytic (64%), (14%), solid product (13%) compared mixture BASO:PP (1:2). Also, this mixture, decreased lowest value (~10%), improving sustainable
