Reventas and KBR partnered to commercialize polymer dissolution recycling, expanding high-quality PE and PP recycling capacity while supporting global circular plastics goals.
Reventas, a Scottish recycling technology company, has formed an engineering and licensing alliance with KBR to globally accelerate its plastics dissolution recycling technology. This partnership aims to scale up Reventas' proprietary process, known as Polymer Dissolution Technology (PDT), which recovers high-purity polymers from post-consumer plastic waste. The collaboration combines Reventas' innovative technology with KBR's extensive engineering and licensing capabilities, providing a faster route to market for new recycling capacity.
Reventas' dissolution recycling process specifically targets polyethylene (PE) and polypropylene (PP) waste streams, which are often difficult to process using conventional mechanical methods. The technology purifies plastic by removing colors, contaminants, and complex waste components. It produces recycled pellets with properties comparable to virgin resin, making them suitable for high-end applications like food packaging, cosmetics, and medical products. This physical process uses a non-proprietary solvent under mild operating conditions, distinguishing it from chemical recycling and offering an environmental footprint similar to mechanical recycling. The technology also ensures material traceability, supporting transparency and compliance.
This alliance addresses the increasing demand for high-quality recycled polymers, driven by regulatory pressures and supply chain requirements for more recycled content in products. The technology offers a viable alternative for plastic waste that would otherwise be downcycled, incinerated, or sent to landfills. By providing cost-effective production of virgin-like polymers, Reventas and KBR aim to bridge the gap between growing plastic consumption and limited recycling capacity. The partnership also strengthens KBR's advanced recycling portfolio, adding a solution for polyolefin recycling.
Reventas, founded in 2020, is currently completing the front-end engineering design for its first commercial demonstration plant. This plant is expected to process 10,000 tonnes of recycled high-density polyethylene (HDPE) annually and is scheduled for commissioning in the fourth quarter of 2028. The company has ambitious plans to deploy over 750,000 tonnes of recycling capacity by 2036. This scale-up is crucial for establishing dissolution recycling as a leading solution for circular plastics globally.
Impact on Products:
The alliance will significantly enhance the recycling of polyethylene (PE), high-density polyethylene (HDPE), and polypropylene (PP) by enabling the production of recycled resins with near-virgin quality. This technology is expected to increase the availability of food-grade and medical-grade recycled polymers, reducing dependence on virgin petrochemical feedstocks. The process will also improve recovery rates for complex plastic waste that is currently difficult to recycle, supporting packaging, consumer goods, cosmetics, and healthcare industries in meeting recycled-content mandates.
Impact on Chemical Commodity Prices (ChemAnalyst)
The Reventas-KBR partnership is expected to have a long-term bearish impact on recycled polyolefin prices while gradually influencing virgin polymer markets. As dissolution recycling capacity expands, the supply of premium recycled HDPE, PE, and PP is likely to increase, easing supply constraints for high-quality recycled resins. This could narrow the price premium currently commanded by food-grade recycled plastics. In the near term, the impact on virgin HDPE, LLDPE, LDPE, and PP prices tracked by ChemAnalyst will remain limited because the first commercial plant is scheduled for 2028. However, over the medium to long term, wider deployment of this technology could reduce demand growth for virgin polyolefins, particularly in packaging applications where regulatory recycled-content requirements are increasing. Solvent demand is expected to remain stable since the process utilizes widely available, non-proprietary solvents under mild conditions. Overall, the development strengthens circular polymer supply while exerting gradual downward pressure on premium recycled and eventually virgin polyolefin prices.
