Plastics "Reborn": Boretech Brings New Life to Recycling Through Chemical Conversion

Amid the global challenge of hundreds of millions of tons of plastic waste annually, chemical recycling technology is seen as a key pathway towards a circular economy. Through three major technical routes - glycolysis, microwave-assisted alcoholysis, and the solvent method - targeting PET, PP/PE, and composite/dyed plastics respectively, Boretech has achieved the transformation of waste plastics into high-quality recycled raw materials. These methods not only demonstrate advantages in efficiency and energy consumption but also broaden the boundaries of plastic recycling.

Plastic products have become deeply integrated into modern life, but the environmental burden they bring is increasingly severe. United Nations Environment Programme data shows that global plastic production exceeds 400 million tons annually, yet the recycling rate is less than 10%. Vast amounts of plastic waste are incinerated, landfilled, or enter the natural environment. According to predictions by the Organisation for Economic Co-operation and Development (OECD), global plastic waste will nearly triple by 2060, while the recycling rate is still expected to remain low.

Facing this global challenge, developing efficient and sustainable plastic recycling technologies has become key to solving the plastic pollution dilemma. Unlike traditional physical recycling, chemical recycling technology "reshapes" the plastic structure at the molecular level, enabling true closed-loop cycling and infinite regeneration of plastics. It is recognized as the core technology route for the future circular economy.

Glycolysis is primarily used to process PET bottle flakes and polyester waste textiles. By reacting PET with ethylene glycol to generate the monomer BHET, it achieves high-purity recycling of polyester materials. This process features mild reaction conditions, low energy consumption, and simple equipment requirements, offering high economic feasibility. During the reaction, it can simultaneously and effectively remove dye molecules and heavy metal ions from PET, resulting in a BHET product of extremely high purity. This can be directly used in new PET polymerization production lines to reproduce flakes or fibers, achieving true "waste-to-new" conversion.

Boretech's microwave-assisted alcoholysis technology utilizes microwave energy to achieve a highly efficient reaction process, capable of rapidly depolymerizing PET fragments within 60 seconds - dozens to hundreds of times faster than traditional methods. The advantages of this technology include compact equipment, extremely low energy consumption, and a small footprint. The produced BHET multipolymer can participate in the polymerization reaction alongside PTA, yielding recycled PET chips whose quality rivals or even surpasses that of virgin material, fully meeting food-grade bottle standards. This technology significantly reduces the production cost of high-quality recycled plastics, providing reliable support for brand companies to rapidly increase their use of recycled materials.

Aiming at complex and difficult-to-separate PP, PE plastics, composite packaging, and dyed materials, Boretech's solvent method demonstrates exceptional tolerance and purification capability. This technology, through processes involving organic solvent dissolution, decolorization, filtration, and evaporation, achieves complete separation of the plastic matrix from pigments, additives, and impurities, ultimately yielding high-purity recycled plastic pellets. The performance of the product is close to virgin material levels and can be widely used in high-end injection molding and packaging fields. It genuinely expands the technical boundaries of plastic recycling, providing a practical and feasible solution for "mixed plastics."

Through the three technology routes of glycolysis, microwave-assisted alcoholysis, and the solvent method, Boretech has established a complete and efficient chemical recycling system, practicing the core philosophy of "giving plastics a new life" - treating plastic waste as a reusable resource, rather than a burden to be disposed of.

The promotion of these technologies can not only significantly reduce the risk of plastic pollution but also provide stable recycled raw materials for the chemical and manufacturing industries, reducing dependence on petrochemical resources and contributing to the achievement of carbon neutrality and sustainable development goals.

With the continuous global escalation of "plastic bans" and the increasing environmental awareness of consumers, market demand for high-quality recycled plastics is growing rapidly. Boretech, with its innovative chemical recycling technologies, provides solid technical support for the transformation towards a plastic circular economy and injects new momentum into the construction of "zero-waste cities." In the future green industrial landscape, chemical recycling will no longer be just the end point for waste plastics, but the starting point for their journey into a new life cycle.
