Waste, resources and sustainable procurement

Reducing waste and recycling more

99.%

NGN waste recycled, reused or recovered on in 2022/23

Excavation waste contributes over 99% of NGN’s waste. In 2022/23 we sent 0.21% of our excavation waste to landfill and are on track to achieve our target of less than 0.1% by 2026.

We reduced our amount of waste created by over 4,000 tonnes, overall sending only 0.22% to landfill.

We are working with our contractors and supply chain partners to minimise our waste disposal to landfill and use of primary aggregates in reinstatement

Purchasing sustainably

In April 2022 we launched a new Supplier Code of Conduct to embed sustainability in our supply chain.

Our code is aligned to the UN Sustainable Development Goals. We have set a target to achieve 80% of our supply chain by value compliant with our code by March 2026. By end of 2022/23 we had already achieved 79%.
