Our annual goal of reducing waste to landfill intensity by 3%, as well as annual incentives, are designed to encourage facilities to eliminate waste generation and identify beneficial uses for their remaining waste streams. As we continue to work towards our waste minimization goal of 3% reduction in waste to landfill intensity annually, each of our facilities takes an individual approach to reducing waste. This is just one example of the work our teams are doing across Avient’s facilities to deliver on our annual waste goal of 3% reduction of waste to landfill intensity.
