What's a Greyparrot

Set your throughput and the number of monitored lines. We'll calculate the value Greyparrot would unlock at your facility.

How this is calculated +

Every figure is derived from documented Greyparrot customer outcomes. The calculator scales each scenario by your throughput and monitored-line count using these formulas:

Optimise throughput & uptime
Monitored share of throughput × 4% uplift × £/tonne material value
Optimise throughput & uptime
Capture residue valuables
Throughput × 15% residue rate × 50% recoverable × 30% realistic capture × £/tonne × line multiplier
Source: UK MRF case where 50% of residue line material was found to be recoverable.
Protect output purity
(Monitored lines − 2) × 0.8 catches per year × £47k saved per catch × throughput factor
Source: European MRF — purity drop diagnosed in 12 minutes via Analyzer alert, vs ~38 hours via manual spot sampling. £47k = avoided reprocessing cost.
Replace manual sampling
Monitored lines × £11,880/year baseline × throughput factor
Source: EU PRF documented 66+ hours per month per line of manual sampling labour eliminated.

Blended material value defaults to £140/t. The three multiplier factors (line multiplier, throughput factor, monitored share) calibrate each scenario for facility size — smaller facilities use the conservative end of each range. These are directional ranges, not committed savings; your actual numbers depend on material mix, recovery targets, and operating patterns.

Directional estimate calibrated against six documented Greyparrot deployments. Your actual numbers depend on material mix, recovery targets, and operating patterns — pressure-test them in a 30-minute facility review.

Our vision

Beyond sorting optimisation

The challenges faced by facility operators and recyclers are, in reality, value chain problems. Sorting efficiency alone cannot close the loop on plastic waste.

 

We work directly with brands, producers, material science companies and recyclers to transform and connect the plastic value chain, using waste intelligence to align every stakeholder who touches a material before and after it is sorted.
