We apply the waste management hierarchy when dealing with the production wastes that we generate. Our most preferable option is to prevent or reduce the amount of waste that is produced in the first instance. Where this is not possible then we seek to handle the waste in manner that reduces the impact on the environment through recycling, recovery or reuse.

2019 Performance

Overall, our global hazardous waste generation per metric tonne of product increased by 6% (0.8kg), with a 74% increase compared to our 2006 baseline year. However, the amount of hazardous waste produced per metric tonne is small at only 15kg per metric tonne of product produced. Two main factors were predominantly responsible for the increase: changes in product mix and a weakened market for the recycling of waste solvents.

Non-Hazardous Waste

This is the first year we are reporting non-hazardous waste as a metric. We initiated the global collection of data in 2017 and as such, the baseline year for this metric differs to the 2006 baseline year used for other environmental metrics reported. Overall, our global non-hazardous waste generation per metric tonne of product increased by 27% since 2018, with a 1% increase compared to our 2017 baseline year. However, the amount of non-hazardous waste produced per metric tonne is small at only 32kg per metric tonne of product produced.

2019 Waste Reduction Activities

Our waste reduction activities in 2019 include:

  • Our Herne, Germany, and Ellesmere Port, UK, sites recycled 3,820 product and raw material IBC containers helping to save over 148 metric tonnes of steel, 57 metric tonnes of plastic and 390 metric tonnes equivalent of CO2.
  • Herne, Germany, has also minimized hazardous waste production by removing methanol as a solvent used in the manufacturing process of a key fuel additive product, reducing the amount of the effluent disposed by 77%.
  • Recycling of material from demolition of a former mercury cell hall building recovered 1,745 metric tonnes of steel and three metric tonnes of lead that were sent off site for recycling.
  • Midland, TX, US, has installed additional containers to improve the recycling of its non-hazardous waste.
  • Castiglione, Italy, has reduced the sludge and acid waste produced by one of their main production plants through the implementation of organizational and managerial improvements, increasing the awareness of operators, optimizing the product mix production processes and upgrading the waste production monitoring system.
  • St-Mihiel, France, has improved the removal of sludge extract from its bioplant to prevent its discharge into the environment.
