Following an update of Standard 306 on Waste by GRI164,which occurred in 2020, a project was launched aimed at defining waste streams for the main Group Companies (in particular the Companies of the Water Segment, those of the Environment Segment, Acea Produzione and Areti).
For a greater level of detail, streams were defined for process and non-process waste. The latter category includes waste that does not derive from production activity in a strict sense, and generally represents a minimal part of total waste, also having a very variable composition determined by non-recurring events.
Table no. 69 – Total waste produced (2019-2021)
| waste produced (t) | 2019 | 2020 | 2021 |
|---|---|---|---|
| t | |||
| total waste | 306.940 | 308.713 | 347.487 |
| hazardous | 78.388 | 70.763 | 67.627 |
| non-hazardous | 228.552 | 237.950 | 279.860 |
| detail by type of processing | |||
| entirely recovered waste (*) | 112.479 | 111.474 | 157.770 |
| entirely disposed of waste (*) | 194.461 | 197.239 | 189.717 |
| waste-to-energy | 1.824 | 3.769 | 2.962 |

(*) Waste sent for recovery in 2021 was divided as follows: 109,759 t for preparation for reuse, 44,984 t for recycling 3,027 t for other recovery operations.
164The previous version of the Standard, from 2016, grouped effluents and waste together.
