Finland — Syklo licence
50,000 tonnes per annum across mixed rigid and flexible waste plastics under BOSS licence at Hyvinkää — the first international commercial-scale deployment.

Improve Chemical Recycling using BOSS for Feedstock Preparation
BOSS technology separates mixed post-consumer waste plastic into cleaner, more consistent polymer streams, improving feedstock quality for pyrolysis, solvent-based recycling and other advanced recycling processes.
The industry challenge
Chemical recycling starts with feedstock quality.
Chemical recycling technologies are increasingly being deployed to process difficult waste plastic streams — but performance depends heavily on the consistency of the incoming material.
Mixed waste plastic often contains contamination such as PET, PVC, PA, EVOH, paper, metals and multilayer structures. These non-target materials reduce yield, disrupt processing, foul catalysts and increase clean-up costs — undermining the commercial case for advanced recycling before the reactor is even reached.
Feedstock preparation is often the weakest part of the chemical recycling value chain. Optical sorting and manual picking cannot reliably deliver the polyolefin purity that pyrolysis and solvent-based processes require to run at design throughput.
The solution
BOSS technology as the front-end solution.
BOSS (Baffled Oscillation Separation System) uses water-based density separation to isolate polyolefin-rich fractions from mixed waste plastic — a proven upstream stage for chemical recycling operators.
- Separates PE and PP from heavier contaminants
- Concentrates target polymers before chemical recycling
- Removes problematic non-target materials
- Improves consistency of input streams
- Reduces downstream processing costs
- Improves yield and product quality

BOSS sits between waste collection and the chemical reactor — turning a variable, contaminated input into a clean polyolefin-rich feedstock.
Applications
Designed for real-world waste streams.
BOSS handles the mixed, contaminated streams that dominate post-consumer and post-commercial collections — the same streams chemical recyclers are targeting.
Household flexible packaging films
Mixed rigid packaging
Multilayer films
Post-commercial waste plastic
Automotive plastic fractions
Industrial mixed polyolefins
Complementary pathways
Mechanical and chemical recycling can work together.
Right technology for the right polymer stream.
Not all waste plastic streams need chemical recycling. BOSS can create streams suitable for direct mechanical recycling where possible, and direct more complex fractions into chemical recycling where necessary.
This improves overall economics across the value chain, supports the waste hierarchy, and ensures that advanced recycling capacity is used where it delivers the most circular value — not on material that could be mechanically recycled instead.
Commercial proof
Commercially proven at scale.
BOSS is deployed in the UK and internationally, backed by an established licensing model.
Durham UK — flexible film plant

UK commercial base
Existing UK commercial deployments across mixed rigid, flexible and medical waste plastic, plus an established licensing model for third-party operators.
