10.5 Waste and Recycling

Systematic waste management minimizes material consumption and disposal volumes. Safe disposal channels with separation according to the type of waste and economically expedient recycling processes serve this purpose. Production fluctuations and building refurbishment / land remediation work also influence waste volumes and recycling paths.

In 2015, the total volume of waste generated rose by 4.9%. Although the volume of nonhazardous waste fell by 2.5%, the volume of hazardous waste generated rose by 11.1%. This contrast is largely due to the re-categorization of fluidized bed ash from the power plant at the Chempark Leverkusen site, which now has to be classified as hazardous waste. Increased production at the sites in Wuppertal, Germany, and Muttenz, Switzerland, also led to greater volumes of hazardous waste.

The volume of waste disposed of rose by 5.6%. This increase is mainly due to the construction of new production facilities at the Knapsack site in Germany. More information about the distribution of waste according to the different means of disposal is available in:

Bayer serves as a certified waste disposal plant operator at various sites. At these locations, Bayer disposes not only of its own waste but also of waste from third parties (companies not belonging to the Bayer Group). For that reason, the volume of waste disposed of differs slightly from the volume of waste generated by Bayer.

In 2015, the volume of recycled waste was 295,826 metric tons. Expressed as a proportion of the total waste disposed of, this represented an increase from 29% in 2014 to 31% in 2015. Site-specific reasons such as changes to the product portfolio, other production volumes, variations in the intensity of construction measures and recycling projects were key to this.

Recycling

In addition to satisfying economic and environmental criteria, the recycling and treatment of our materials also has to comply with legal requirements. This results in restrictions, in particular in the areas of pharmaceuticals and crop protection. Throughout the Group, we are developing opportunities for recycling within the framework of legal regulations.

Examples of recycling measures provide proof of Bayer’s commitment to recycling.

Production-related recycling at HealthCare is conducted in line with the requirements of the relevant production site. When determining the best means of disposal, recycling options are explicitly included, and are to be considered preferable to landfilling or incineration.

Material-based recycling is important in CropScience’s active ingredient and intermediate product production. For reasons of resource efficiency, solvents, catalysts and intermediates are repeatedly processed and returned to the production process. Since these are recycling steps that are closely linked with the process, there is no global regulation. Material-based recycling is regulated separately at each production site and production plant. In the global process development of active ingredients and intermediates, material recycling is considered an important development criterion. In accordance with CropScience’s global Environment Policy, all CropScience sites are obliged to prevent, recycle and reduce waste and dispose of it safely and in line with good environmental practices.

The subgroups select the best means of disposal for any given waste type at the production site based on the applicable national or local legal requirements, the technical possibilities available on site, environmental protection aspects and the internal hierarchy of waste disposal.

No product-related recycling is possible for the HealthCare portfolio because pharmaceutical products are subject to strict quality requirements. Packaging materials are recycled in line with national regulations as part of the national infrastructure for waste disposal.

CropScience does not generally take back crop protection products it has sold. Packaging materials are disposed of or recycled in line with national legislation. In many countries where there is no legal regulation, the industry has set up a returns system in collaboration with other providers.

Returns of obsolete stocks of crop protection products are only conducted in individual cases where there is good reason. However, the crop protection product industry has set up voluntary initiatives in various countries that enable farmers to ensure obsolete stocks are disposed of safely. As part of its activities in the CropLife association, CropScience is working with the United Nations’ Food and Agriculture Organization (FAO) and the World Bank to support the proper collection and disposal of obsolete stocks in Africa.

In its own production operations, Covestro also uses material recycled from plastic waste. These kinds of high-quality secondary raw materials are used to manufacture certain grades of engineering thermoplastics. A flame-retardant plastic compound for television set housings, for example, comprises 30% recycled PET water bottles.

The Global Sideline Business unit at Covestro sells unwanted plant and tools on the open market, thus feeding them back into circulation. Approximately 150 tangible assets were sold to third parties worldwide in 2015. Scrap metal from plants is returned to the material cycle. In 2015, this amounted to around 1,600 metric tons in Germany alone.

Covestro is actively committed to recycling through its involvement in associations such as PlasticsEurope and to the avoidance of plastic granule wastage in industrial plants through the Zero Pellet Loss initiative. The company is also a shareholder of BKV GmbH, German industry’s competence platform for recycling plastic.

Using conventional recycling measures, Currenta was able to return approximately 45,000 metric tons of building materials, FGD gypsum is a by-product of flue-gas desulfurization (FGD). and slag, 14,300 metric tons of metal and 15,800 metric tons of chemicals such as sulfuric acid and solvents to the material cycle in 2015.
