In 2025, Contact Energy reported a total waste generation of 134 metric tonnes, of which 6.94% was recovered through recycling, reuse, or composting.This low recovery rate highlights limited waste diversion and suggests that Contact Energy may be relying more heavily on landfill or incineration, underscoring opportunities for stronger resource recovery initiatives.a
Since 2019, Contact Energy's total waste generation increased by 6.26%, including a 10.74%increase in 2025, indicating a persistent upward trend that may reflect scaling operations, inefficiencies in resource use, or a lack of effective waste minimization practices.a
Over the same period, Contact Energy's waste recovery rate increased by 157.4%, including a 21.71% rise in 2025, indicating growing emphasis on circularity and improved operational practices for diverting waste from disposal.a
Overall, Contact Energy has seen a consistent rise in waste generation both over the long term and in the year 2025. However, the company has also steadily improved its waste recovery performance, suggesting that it is actively working to offset the environmental consequences of increased production through enhanced circularity efforts.
