Technology

How BOSS separates hard-to-sort plastic streams.

BOSS uses water-based density-separation principles to create a commercial route for streams that are hard to recover cleanly through conventional sorting alone.

The problem

Mixed plastic is valuable, but difficult to sort consistently.

Processors need predictable output quality, plant integration, and a clear route to recovered material value. Yield, purity, capacity and throughput figures are treated as claims until validated.

Contaminated streams

Mixed polyolefin and flexible streams can carry overlapping visual characteristics, residues, labels, and density profiles that make high-value recovery difficult.

Commercial constraints

Operators need a process that can be assessed against site footprint, feedstock variability, operating cost, and offtake requirements.

Evidenced material recovery

Each deployment is scoped against specific feedstock and target output, with validation steps agreed before commercial claims are made — giving buyers and brand partners traceability evidence they can use in their own reporting.

BOSS architecture

Three stream families, one separation principle.

The BOSS technology family covers rigid, flexible and fibre material dimensions — each applying density-separation principles adapted to the presentation, contamination profile and commercial requirements of the target stream.

Mixed rigid plastics

TO VALIDATE

BOSS-3D

Water-based fluid dynamics and oscillation separate polymers within mixed rigid streams by consistent density differences — targeting PE and PP recovery from post-consumer household and commercial collections where conventional optical sorting struggles.

Laminate and multilayer film

TO VALIDATE

BOSS-2D

Addresses separation challenges in flexible packaging, laminate and multilayer film — formats typically too complex for standard optical or air-classification routes. Scoped on a stream-by-stream basis around feedstock presentation and target output.

Fishing net and carpet fibres

TO VALIDATE

BOSS-1D

A fibre-stream variant targeting marine litter and carpet-waste recovery. Applies the same density-separation principles to longer-chain materials with distinct presentation and contamination profiles.

BOSS principle

Density separation, packaged for licensed deployment.

The BOSS process is positioned as a technical system that can be scoped around a processor's material challenge, not as a generic recycling service.

Process view

  1. 1. Characterise feedstock. Confirm stream composition, contamination, moisture, and target output.
  2. 2. Configure separation. Tune the BOSS process around material density, fluid behaviour and commercial specification.
  3. 3. Validate output. Test recovered material for purity, consistency and agreed quality requirements before publishing claims.
  4. 4. Deploy under licence. Scope equipment, support, training, and ongoing process governance for the site.

Throughput and modularity

TO VALIDATE

BOSS is deployed as a modular system alongside existing plant infrastructure. Throughput, footprint and integration requirements are scoped during technical due diligence — each site assessment is specific to the feedstock, available space and commercial target, rather than a fixed equipment specification.

FAQ

Common questions for processors and brand teams.

Questions from processors considering a licensing conversation and brands evaluating UK-processed PCR supply.

BOSS is designed for mixed plastic streams where density separation can recover material that is difficult to sort through conventional routes. Stream-specific claims need feedstock testing and source evidence before publication.
