Learn how the mechanical recycling of plastics is helping make polymers more sustainable within the materials ecosystem.
Mechanical recycling is the most commonly used process by which plastic waste is turned into new products without the structure of the material being significantly altered. It uses less energy than other forms of recycling, but it does have limitations. For example, highly regulated plastics such as those used in food packaging currently cannot be produced by mechanical recycling at scale due to quality, performance, and safety restrictions.
Plastics are broken down in size. Processes such as grinding, re-granulating and compounding are used.
The plastics are then washed in a series of tanks to remove any remaining contaminants. Detergents and antifoam agents can improve the quality and consistency of post-consumer recycling (PCR) streams.
Plastic manufacturers can reuse these materials for plastic applications with less performance needs, such as trash bags, rigid plastic containers and building materials.
Dow acquired Circulus, a leading recycler of plastic waste into post-consumer resin (PCR). Dow's expertise in materials science and high-performance resins combined with Circulus' mechanical film recycling capability will allow Dow to enhance its offerings in applications, such as collation shrink packaging, stretch film, liners and select food packaging, to a wider range of applications in the industrial, consumer, and transportation markets.
To transform recyclable plastics that are difficult to recycle, like film plastics from discarded food packaging, mechanical recyclers need detergents and antifoam agents to improve the quality and consistency of post-consumer recycling (PCR) streams. These agents remove surface contaminants such as adhesives and control foaming to enable greater water circularity. Innovative products like EVOWASH™ detergents and antifoams improve the quality of recycled plastic while maximizing the reuse of processed water.
A key tool in closing the loop is mechanical recycling.
