Waste management

How we’re abandoning the throw-away mindset

By 2030, we’re aiming to move towards zero waste as a company. We’re committed to taking proactive steps to reuse all our waste and reuse water at all our most water intensive sites.

Waste reduction remains one of our key environmental performance indicators. We focus on reducing waste generation in our manufacturing processes as part of our resource productivity program.

We’re also committed to reusing and recycling obsolete materials and continue to promote a circular economy.

 

Our ambition

100% reusable waste by 2030

Our progress

- Waste reuse: 58% (reduction compared with 2018 baseline)

- 40% reduction in waste per ton since 2011

An overview of material flow in our processes

Our approach

We focus on reducing waste generation in our manufacturing processes as part of our resource productivity program. Examples of our waste reduction projects include installing solvent recovery units, reducing packaging waste by moving from smaller paper bags or metal drums to bulk deliveries of raw materials, and reworking obsolete finished goods.

To help increase our contribution to the circular economy, new uses have also been identified for materials that would otherwise have been disposed of as waste. This has resulted in a waste avoidance of 8,500 tons.

Adopting circular alternatives

In partnership with Alucha, one of our inaugural Paint the Future winners, we’re piloting the use of paper waste to make paint. It involves using a circular raw material that Alucha extracts from paper sludge as an alternative to calcium carbonate.

Increasing our water reuse

To reduce freshwater intake and wastewater discharge, we treat wastewater at on-site treatment plants, or via third parties, and reuse it in our plants. We also recover and reuse materials present in the process water whenever possible.

Raw materials for others

We’re constantly striving to find solutions for reducing our waste. One of the many ways we do this is by maximizing any remaining product waste and repurposing it as a raw material that can be used by other companies. A good example is reusing wastewater sludge by turning it into bricks and tiles.
