The enzymatic PET recycling technology has entered the factory validation stage. According to Plastic Today, Rhea’s Factory and Niagara Bottling will conduct validation of the enzymatic PET recycling technology at a factory in California. The project has received a $3 million funding from the US Department of Energy (DOE) to evaluate the feasibility and stability of the recycling process in actual production environments. Compared with traditional mechanical recycling and chemical depolymerization routes, enzymatic PET recycling utilizes biological enzymes to selectively decompose polyethylene terephthalate. Theoretically, it can process colored, multi-layered, or contaminated PET waste and reduce dependence on raw material purity. This validation at the Niagara Bottling factory means that the technology will move from the laboratory to continuous production scenarios, with a focus on examining the yield, energy consumption, and quality of recycled materials after process scaling up.
Significance for the polymer additive industry
The industrialization of enzymatic recycling routes will directly affect the application boundary of recycled PET in the packaging field.
. For the polymer additive industry, as the proportion of recycled materials increases, the thermal history and residual impurities during processing will accelerate material degradation, placing higher demands on the formulation design of antioxidants, light stabilizers, and ultraviolet absorbers. Especially in bottle to bottle closed-loop recycling, the molecular weight distribution and carboxyl content of recycled PET fluctuate greatly, requiring a more precise polymer additive system to maintain processing stability and the weather resistance of end products. In addition, if the enzymatic hydrolysis process can operate stably at the factory end, it will increase the supply of food grade recycled PET and drive the demand for functional masterbatch in the modification of recycled materials. Compatible and chain extending additives such as maleic anhydride grafted wax can be used to improve the melt strength and processing flowability of recycled PET, helping to maintain stable performance of recycled materials in processes such as blowing and injection molding. With the advancement of the verification project, the auxiliary solution for recycled PET is expected to become a new growth point in the polymer additive market.
