Summary: Plastic waste has grown significantly in recent years, causing a global environmental issue known as white pollution. However, plastic waste also contains valuable carbon and hydrogen content, which can be converted into high-quality oil using supercritical methanol. The experiment showed that increasing temperature and reaction time promoted the conversion of polypropylene (PP), resulting in a higher oil yield. The oil obtained primarily consisted of hydrocarbons and oxygenates, and the composition varied more significantly with temperature rather than reaction time. The study concluded that supercritical methanol is a feasible solvent for converting plastic waste into high-quality oil, offering a potential solution to plastic pollution.

Summary: The green extraction of SCFE-CO2 with co-solvent methanol can produce a more complete phenolic acid composition and a higher quantity, without toxicity. The extraction process involves using 100 g of Quercus infectoria gall of size 0.3 mm, with a temperature of 60 & DEG;C, pressure of 20 MPa, and a co-solvent methanol flow rate varying from 0.05 to 6 ml/min for 60 min. The analysis showed that this method can identify about 27 phenolic compounds, and the flow rate of methanol co-solvent significantly affects the extraction outcome up to a flow rate of 0.5 ml/min, with no further impact beyond that.
