What happens to it
The recovery or disposal code those sites recorded most for 10 01 01 in 2024 (the code each site used for most of its tonnes):
| Code | Means | Sites |
|---|
| D15 | storage pending disposal | 17% |
| D5 | | 17% |
| R5 | recycling other inorganic materials | 15% |
| D1 | deposit into or onto land (landfill) | 13% |
The right code is the one on your own permit and transfer notes - this is what other sites did, not a rule. R and D codes explained.
