AI-Assisted Kinetic Modeling of PLA Hydrolysis Under Subcritical Water Conditions for Sustainable Polymer Recycling
Abstract: The accumulation of poly (lactic acid) (PLA) in terrestrial and marine ecosystems has intensified the demand for closed-loop, green recycling technologies. Subcritical water (SCW) hydrolysis offers a promising, catalyst-free pathway for the rapid depolymerization of PLA into its constituent monomer, lactic acid. However, the complex, highly non-linear kinetics governing macro-molecular degradation under variable hydrothermal conditions limit real-time process optimization and industrial scalability. This study develops a novel artificial intelligence (AI)-assisted …

Low cost method for fuel production from Plastic waste
Abstract: There is a huge problem of plastic waste remaining bulbous, eventhough many solutions are put forth. The production of synthetic plastic has reached 400 million tons worldwide, from which 50% is thrown in landfills or recycled; 15 million tons reach seas and oceans.Inceneration and other waste management methods have many limitations, which includes hazards of secondary pollutants. And moreover, there is no more land filling space for waste accumulation. Land …
