Significant events
- “To this end, 2024 has been a year of investment in our groundbreaking and industry leading de-inking facility. This enables printed sheet to be returned to Corplex, have the ink safely and cleanly removed and then the sheet is returned to white pellet for use in all products, creating a true closed loop solution. This also mitigates plastics packaging tax for us and our customers where it may be applicable. This went live in April 2025.”

Each % is (latest − prior) ÷ |prior| for the line item as filed. The comparison is only shown when the latest and prior accounts cover broadly equal-length periods — short or long stubs (typical around incorporation or a year-end change) are suppressed rather than misrepresented. Lines a company doesn't report are omitted. About these numbers
