Outflow of resources: Waste

Policy

When products leave our operations, we aim to process them to the highest possible standard. Raw materials are reused or remanufactured wherever possible and recycled where reuse is no longer feasible. We seek to minimise the landfilling of materials. These activities take place within our own operations and in collaboration with suppliers and waste processors in the upstream value chain. In this way, we minimise waste wherever possible. ^{(ESRS 2 MDR-P, 65a,b, E5-1 para 16, AR 9a)}

KPI

It is our ambition to reduce the total amount of residual waste within our organisation to less than 5% and to increase our waste separation rate to at least 85%. We have mapped 107 waste streams in order to improve the separation rate. At a large number of our locations, we are already achieving this ambition. Continuing to meet this ambition remains a constant point of attention. See the ‘Measures’ section for how we are doing this. ^{(MDR-T 79b, MDR-T 80a,b,c, E5-3 24e, 25)}

Measures

Within our operations, we focus on increasing the waste separation rate. For example, collection and separation behaviour at environmental streets is included in the programme for our safety days. We also analyse separation and incineration rates per location. Based on these analyses, we implement tailored initiatives for each site, including the deployment of a waste coach.  ^{(ESRS 2 MDR-A 68a,b,c)}

Together with our waste processor, we continuously seek high-quality applications for our waste streams and work to further reduce residual waste. ^{(ESRS 2 MDR-A 68a,b,c)}

Measuring progress and results

We have developed a dashboard for internal use to monitor separation and recycling rates from 2026 onwards. In 2025, total waste amounted to 34,553,058 kg. This waste was delivered to the waste processor across 107 waste streams, of which 93% could be recycled. We receive detailed information from our waste manager on the volume of waste by stream and the type of processing applied. ^{(MDR-T 77a, c, MDR-T 79, E5 40)}

Total waste volumes increased significantly in 2025 compared to 2024. Due to the growth of investments on the expansion, management, and maintenance on our grid, waste streams also increase. Compared to 2024, we saw particularly strong growth in soil, rubble, stone, and concrete, as well as cable waste. Residual waste also increased, by 56.2%, as higher investments in our grid inevitably lead to additional residual waste streams. Various initiatives have been launched to specifically reduce residual waste. In 2025, ‘handling our waste streams’ was part of the health and safety days at all Enexis locations, with participation from both employees and contractors.

Hazardous waste contains substances that are, or may be, harmful to human health or the environment. The European Waste List (EURAL) specifies which substances fall into this category.

Products in waste streams specific to us as a grid operator

The waste we generate contains the following materials: ^{(E5 38 a,b)}

We occasionally dispose of radioactive waste, for example when decommissioning power transformers and medium-voltage installations. ^{(E5 39).}
