In line with the circular economy, we work to reduce or eliminate waste in our operations and keep resources in use for as long as possible.

We first focus on reducing waste generation at the source. We then work to identify and implement reuse and recycling opportunities and manage materials in an environmentally protective manner following the principles of the circular economy.

Our waste management standard requires all sites to have a site waste management plan; an inventory of all waste streams generated onsite; onsite waste storage areas that meet all local regulatory requirements; a comprehensive waste training program; and tracking of non-hazardous and hazardous waste metrics.

Our landfilled waste decreased 4.2 percent in 2020 compared to the prior year. This was primarily due to the curtailment of the Intalco smelter in the United States and the completion of several significant housekeeping- and maintenance-related activities.

Our goal is a 15 percent reduction in landfilled waste by 2025 and 25 percent by 2030 from a 2015 baseline. We achieved a 14.4 percent reduction through 2020.
