THE CHALLENGES WE SOLVE

What MRF operators tell us keeps them up at night

01

You're reacting 24-48h too late

By the time a manual sample reveals a purity drop or composition shift, the damage is done. Entire shifts of material have already moved through the line, and issues compound long before anyone notices.

Greyparrot solution

Real-time alerts & intervention

02

Equipment, throughput, and uptime run on guesswork

Trialling machinery settings, cutting belt idle time, justifying a new optical sorter, proving a cleaning schedule worked: all done on intuition and the occasional sample. With feedstock composition constantly shifting, the inputs you're optimising against never stand still.

Greyparrot solution

Data-led optimisation & ROI

03

Manual sampling is slow, costly, and leaves audit gaps

Manual sampling ties up operator hours physically handling waste to cover less than 0.1% of throughput. The same sampling effort underpins PRO and regulatory reporting: staff time, lab fees, safety risk, and audit gaps between trials.

Greyparrot solution

Continuous AI monitoring & automated reporting

WASTE INTELLIGENCE

Three ways waste intelligence pays for itself

Continuous waste analytics creates value across three distinct areas, each builds on the last. The more lines monitored, the greater the return.

01. RESPONSIVE OPERATIONS

Act on problems in minutes, not the next day

Real-time alerts let operators respond to composition shifts, throughput drops, and equipment issues the moment they happen, not 24-48h later. Live infeed blending alerts prevent valuable material entering the wrong product stream. Throughput monitoring flags underutilised lines before recovery losses compound.

  • £47,000 saved in one incident, purity drop diagnosed in 12 minutes
  • +200 tonnes/month (+9% production) via throughput & blending alerts
  • Email and SMS alerts, operators act wherever they are

£47,000

saved in a single incident through real-time purity alerting

02. OPTIMISATION

Maximise equipment, throughput, and uptime

Detailed material data surfaces actionable insights on machinery performance, throughput patterns, and downtime that no manual process can match. Customers use Greyparrot to trial optical sorter settings, cut "black belt" idle time, quantify maintenance changes, and build data-backed cases for equipment upgrades, with before-and-after numbers that speak for themselves.

  • Residue mass reduced 17% after data-led optical sorter recalibration
  • Black belt idle time cut from ~5h to ~2h per shift, 110–190 extra tonnes per shift
  • Unrecovered material value reduced 20% post-optimisation

£408k/yr

annual saving after data-led sorter & throughput optimisation

03. CONTINUOUS MONITORING

Reduce manual sampling for operations and compliance

Manual sampling is slow, costly, and hazardous, and the same effort underpins PRO and regulatory reporting. Staff spend hours every month handling waste by hand, covering less than 0.1% of throughput. Greyparrot eliminates both at once: continuous AI monitoring runs 24/7 across 100% of throughput, audit-grade and timestamped.

  • £11,880/year saved on a single product line (UK MRF)

  • H&S risk eliminated, no staff contact with waste samples

  • Audit-ready composition data for PRO, regulators, and customer contracts

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.
Reduce 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.

EVIDENCE

Real outcomes from real facilities

Optimisation · Optical sorting

−17% residue mass per day

A recovery facility used Greyparrot to trial optical sorter configurations across four test periods. Baseline settings outperformed all alternatives. Post-recalibration, average daily residue fell from 54.5t to 45.3t, saving £310,000 in disposal costs annually and recovering 20% more unrecovered material value.

Responsive operations · Purity alert

12 min to diagnose a £47,000 problem

A control room operator spotted a purity drop on the live Greyparrot dashboard. Investigation revealed liquid from bottles had obscured an optical sorter sensor. Cleaned, restarted, purity restored. Without real-time alerting, the issue would have gone unnoticed until the next manual sample, costing up to £47,000.

Responsive operations · Throughput

+200t per month production uplift

Green Tech (Lithuania) deployed a single Analyzer on an infeed line to a PET wash process. By using throughput and blending alerts to optimise infeed composition in real time, they increased total production by 200 tonnes per month, a 9% uplift from one unit on one line.
