BOSS-3D: Mixed Rigid Plastic
BOSS-3D technology separates the ‘hard to recycle’ stream of mixed rigid waste plastics by amplifying slight differences in relative densities between polymers through the manipulation of fluid dynamic principles of water. Our patented system uses oscillation to generate specific flow patterns in the water, which affect different polymer types in different ways. This novel process technology effectively stratifies different polymers based on density, allowing us to split particles with a density delta of 0.005 gcm-3.
BOSS-2D: Laminate & Multilayer Plastic Film
Just 4% of post-consumer film packaging is currently recycled; by far the lowest percentage by plastic category. Near infra-red (NIR) technology cannot easily identify, and hence separate, laminate and multi-layer material, which together can account for up to 20% of the post-consumer plastic film fraction. These are harmful contaminants in the compounding process, clogging screens, interrupting production and preventing film recycling on a large scale.
With no automated separation solution available on the market, post-consumer flexibles are either sent for incineration or exported to overseas markets where it can be dumped in landfill and waterways creating long term local and global environmental problems.
Following successful laboratory scale testing of a new innovative design for our BOSS technology on plastic film, we are developing a commercial scale prototype. The design takes into account the forces acting on film to produce a new blade stack and shell to create a ‘BOSS-2D’ technology that separates post-consumer flexibles. The first technical goal is removing laminate & multilayer film from “prime” polyolefin film.
BOSS-1D: Fishing Net & Carpet Fibres
The vast majority of waste fishing nets end in landfill or remain in the ocean where they account for up to 46% of all ocean plastic. The United Nations Environment Program (UNEP) estimates that discarded fishing gear in our oceans make up approximately 10% of the annual marine litter (640,000 tons each year).
2 million tons of waste carpet (89%) are landfilled in the US each year with a recycling rate of just 5%. In the UK 300,000 tons are landfilled each year although the recycling rate is higher at 25% (100,000 tons).
The chronically low recycling rates in the plastic fibre industry reflects the dearth of automated technology capable of separating 1D waste plastic material. We have focused our R&D on fibre with laboratory scale trials revealing positive results with high purity outputs. We are in the process of developing a commercial scale ‘BOSS-1D’ technology that will separate fibres from waste fishing net and waste carpet into very pure recycled materials.
Global brands, supported by consumers, are committed to recycling product through campaigns like the Ellen McArthur “Plastic Pact”. This has led to an increased demand for high quality recycled product and; ergo, technologies that can deliver high purity recycled material at scale.
Chemical recycling is capable of producing near virgin like recycled resin. However, the process requires very pure feedstock; BOSS mechanical recycling technology unlocks the economics of chemical recycling technology by supplying pure post-consumer feedstock with no production losses to black or dark plastics because BOSS is a water-based density separation technology.
BOSS technology compliments and enhances the economics of both the mechanical and chemical recycling technology industries.
