Waste
Eneco’s vision is to minimise the creation of waste and to strive for optimal environmental protection in a sustainable and cost-effective manner. Eneco makes confident choices, takes responsibility and seeks alignment.
Eneco’s long-term objective is to:
- Reduce the percentage of residual waste at the sites to as close to 0% as possible.
- Have a maximum of 5% residual waste by 2025.
- Use other waste streams as renewable raw materials.
- Have the unavoidable minimum residual flow processed by a certified waste processor.
- Have our suppliers reuse packaging materials as much as possible.
- Consider in advance how raw materials can be reused when constructing new assets and purchasing materials.
