Process: Paper Recycling Report (Band 9)
Band-9 Task 1 process report on paper recycling, with circular-economy framing, stage vocabulary, and loop-structure technique.
The diagram shows how waste paper is recycled into new paper products. Summarize the information by selecting and reporting the main features.
A Band-9 model report
The diagram presents paper recycling as a nine-stage circular system, converting discarded print into fresh paper through cleaning, pulping, and reforming.
Overall, collection feeds mechanical and chemical purification before the cleaned pulp is reformed, dried, and finished — with unusable residues extracted at three separate points. The loop closes when new paper re-enters use.
Collection opens the cycle: sorted waste paper is conveyed to pulpers, where water and agitation reduce it to slurry. Screening then removes large contaminants — staples, plastics, string — while centrifugal cleaning ejects heavier grit. De-inking follows: air bubbles lift print particles to the surface for skimming, the subtlest and most chemical stage.
The cleaned pulp is refined, bleached for whiteness, and spread onto wire mesh where water drains, leaving interlocked fibers. Pressing squeezes remaining moisture before heated rollers dry the sheet completely; calendaring irons it smooth. Finally, the finished rolls are cut, packaged, and dispatched — destined, in time, to return as waste paper again.
Notably, residues exit at screening, cleaning, and de-inking — purification's price at each gate. The system is a loop with leaks by design: fibers shorten each cycle, so fresh pulp must periodically replenish. Recycling delays, rather than defeats, entropy.

Examiner notes: why Band 9
Task Achievement (9): Overview establishes circularity (nine stages, three residue exits) before sequencing. Each purification mechanism distinguished; the fiber-shortening caveat shows genuine understanding.
Coherence & Cohesion (9): Collection/purification/reforming sequence with mechanism-specific transitions. "Loop closes" framing opens and completes the circle.
Lexical Resource (9): Recycling precision: "slurry," "centrifugal cleaning," "de-inking," "skimming," "calendaring," "entropy." Technical terms correct and contextualized.
Grammatical Range & Accuracy (9): Passive for processing stages, active for interpretation, em-dash qualifications. Exact.
High-scoring phrases
- circular system — loop framing
- purification's price — residue cost (elegant phrase)
- lifts print particles — de-inking mechanism
- interlocked fibers — paper formation image
- loop with leaks — imperfect circularity
- delays, not defeats, entropy — scientific-philosophical close
Quick answers
Circular processes: how do I show the loop?
State circularity in the overview (waste paper re-enters as new product) and close by completing the circle. Loop announced and loop closed.
Cleaning stages sound repetitive. How do I vary them?
Name each cleaning mechanism distinctly: screening removes solids, de-inking lifts print, bleaching restores color. Mechanism specificity defeats repetition.
