11. Usage of Natural Resources

The company discloses the extent to which natural resources are used for the company’s business activities. Possible options here are materials, the input and output of water, soil, waste, energy, land and biodiversity as well as emissions for the life cycles of products and services.

Material efficiency at Werner & Mertz
At its Mainz and Hallein sites the Werner & Mertz Group relies on plant-based materials in all raw material areas. To promote biodiversity, the Group uses surfactants and soaps that come from a variety of plants such as rapeseed, sunflowers, olives and flax. Surfactants and soaps made with European vegetable oils are becoming more important. Other raw materials, like organic acids, solvents and thickening agents from natural resources are used for our products. Some of the raw materials, e.g., bio ethanol, lactic acid, citric acid and xanthan gun, are produced from the fermentation of vegetable oils such as rapeseed oil, corn and wheat and sugars. When waxes are used, natural resources such as beeswax and carnauba wax are tapped. In general, the input quantities of additives, raw and working materials and the changes to the individual materials depend on the range (article mix) of products manufactured.

Werner & Mertz uses the following measurable means to reduce the use of natural resources at both sites:

Water and Wastewater at the Sites                      
Environmental performance figures for the use of water and wastewater at the Mainz site are on pages 30 and 31 in the Environmental Statement 2020.

Water at the Hallein site is drawn from the company's own well and from the municipal water supply network. A large portion of the treated water flows into the manufacturing of our products. Since the beginning of 2006, we have tapped our on-site well for up to 80 cubic meters of water per day, which we demineralize for production. We also take 15 cubic meters of water from the well every day for cooling purposes. Because the water does not come into contact with products or other operating materials, it remains uncontaminated and flows into the Salzach. Groundwater abstraction helps to lower the naturally high groundwater level in the Neualm district.  

From the production buildings, the water used mainly for cleaning purposes is treated and then directed to the Greater Salzburg Conservation Association water treatment plant. The increase in water use since 2016 is attributed to the more complex cleaning and rinsing cycles in the shoe polish manufacturing and filling processes as more frequent material change-overs are required for these products. These measures ensure that the product quality remains the same at the production site.

Figures and Units of Measure for Use of Natural Resources  
For the Mainz site the units of measure and concrete figures are reported on pages 35-36 of the Environmental Statement 2020. They provide information about the quantities of key natural resources used for business activities. 

The units of measure and figures for the Hallein site are:
