Methodology, assumptions and sources

What the numbers on this site are, how they were built, and where each factor comes from.

The quarterly series

Modelled

The quarterly series is a ramp model built on the scenarios of the 2021 business plan. It is not audited accounting, and it is not a record of realised production. Every environmental, social and economic figure labelled Modelled is derived from that series through the formulas published on each metric card.

On the 2021 prices

2021 plan projection

The prices in the business plan correspond to a market peak. Return scenarios built on them should be read as an upper bound of the price environment, not as a central case.

On the emission factors

The avoided-emissions factor of 1.7 kg CO2e per kg of rPET is a European reference from denkstatt, pending an own life cycle assessment. This matters concretely: the Venezuelan electricity mix and diesel self-generation will make the real factor differ, and the direction of that difference is not assumed here.

  • Scope 1 of 0.25 kg CO2e per kg of flake is derived from roughly 75 litres of boiler diesel per MT plus around 18 litres per MT from the generator.
  • Collector productivity of 20 to 80 kg of material per day, of which about 30 % is plastic, is taken from Resources, Conservation & Recycling (2024) and used only to produce a range.
  • rPET 0.45 · PET 2.15 kg CO2e/kg

Formulas

  • bottleMT = flakeMT / 0.75
  • bottlesDiverted = bottleMT × 1000 / 0.030
  • tCO2e avoided = flakeMT × 1.7
  • tCO2e scope 1 = flakeMT × 0.25
  • tCO2e net = tCO2e avoided − tCO2e scope 1
  • USD to chain = bottleMT × bottle purchase price
  • collectors = (bottleMT × 1000 / 90) / 24 … / 6
  • revenue = flakeMT × 900 + (bottleMT × 0.10 × 200)
  • variable cost = flakeMT × 94
  • contribution margin = revenue − variable cost − quarterly fixed cost
  • utilisation = flakeMT / (1.5 × 0.75 × shift hours × production days in quarter)
  • direct jobs = 12 through 2025 Q4, 20 from 2026 Q1
  • flakeMT — manual series input
