| Class | Examples of type of waste | Environmental features |
|---|---|---|
| A | Damaged, faulty goods rejected at paper mill. | Marginal environmental benefit; contains no post-consumer waste; no de-inking required. |
| B | Printers and converters trimmings, off-cuts; faulty unprinted items (eg. envelopes). | Indirect environmental benefit; limited post-consumer waste; no de-inking, little cleaning required; energy saved as fresh pulp is replaced; fossil fuels conserved. |
| C | Office correspondence; computer printouts; top class printed literature, books, quality brochures. | Significant direct environmental benefits; almost all post-consumer waste; de-inking, cleaning and non-chlorine bleaching (where required) all done responsibly; land-fill or incineration pollution avoided; fresh pulp replaced so energy saved; fossil fuels conserved. |
| D | Newspapers, magazines, comics; cheap catalogues, directories. | Greatest environmental benefit; all post-consumer waste, mainly ex-household; de-inking, cleaning and non-chlorine bleaching (where required) all done responsibly; major land-fill or incineration pollution avoided; fresh pulp replaced, so energy saved; fossil fuels conserved. |
