2.1 Environmental management approach

    2.1.1 Operational environmental protection

      Noise complaints

      GRI  
       

      We work tirelessly to minimize noise pollution at our locations and rigorously follow up on any information and complaints. In the reporting period we received and dealt successfully with two complaints concerning noise.

      At our location in Garching, one local resident complained to the district council about noise being emitted from the Voith site. The investigations we conducted in consultation with the district council identified the cause of the noise to be a compressor-system fan, which was in operation more than usual owing to the high summer temperatures. Fitting a silencer eliminated the source of the noise.

      At our Heidenheim location, one neighbor complained one night about a high-pitched whistling noise. The noise was caused by a blocked weir-system rake on the River Brenz, which was installed during a construction project.

       

      Nanotechnology

      GRI  
       

      Nanoparticles are embedded in the following products:

      Voith Turbo: Cooling systems for monorails, locomotives, railcars, special vehicles, and high-speed trains. The particular coating process is performed by a service provider, and currently less than 10 kg of material is in field use.

      Voith Paper: Calendar and roll covers in the area of finishings. The NanoPearl coatings represent the latest in calendar cover technology thanks to an improved nanoparticle filler system. According to the manufacturer’s statement, the quartz particles are produced in situ with the resin and are never released at any stage of the manufacturing process. When rubbed during use, the particles are still surrounded by plastic, so they pose no hazard. No particles are released in thermal processing either.

        Green controlling / group-wide data recording

        GRI  
         

        When gathering data, we follow the definitions set out by the international GRI G4 sustainability standard, which also forms the basis for this report. Wherever an additional, directly measurable added value arises for Voith, we also go beyond meeting these requirements.

        Almost 90 Voith locations globally record data on energy consumption every month, and data on waste and fresh water every quarter, using our hse+ sustainability database. The EBM organizations in our Group Divisions and the central function Corporate Sustainability & HSE validate the data, and report it to the Corporate Board of Management on a quarterly basis. Besides data and KPIs, this report includes a listing of resource-conservation measures and their implementation status. Before a measure can be completed, its validity must be checked at the location in question and the result stored in the database.

         

        EBM experts

        GRI  
         

        The work of our EBM experts is underpinned by the legal requirements relating to energy and environment as well as the extensive experience they have gained since 2008 from EBM projects on energy and resource efficiency. Their activities include assessing the cost-effectiveness of measures using lifecycle costs.

         

        Hot-spot analysis methodology

        GRI  
         

        When conducting a hot-spot analysis, the consumption of each control and analysis level (i.e. region, Group Division, location, system, process) is determined and displayed graphically. Data is prepared both according to physical consumption and by associated cost, bringing transparency to “hot spots” with high consumption levels and costs. Based on this, we develop and approximately evaluate project ideas before gradually developing them further, using a stage-gate process through to implementation. As part of this, we employ economic and ecological evaluation criteria, in accordance with our Green Controlling cycle. We regularly review the distribution of consumption based on changing patterns of consumption and general conditions (location activities, economic activity, changes to the fleet of machines and plant, etc.).

            Environmental impact of buildings

            We calculate our greenhouse gas emissions by energy source and based on specific CO2e factors, which we derive from a database as CO2 equivalents. Where possible, we use the specific CO2e emission values of the respective local or regional electricity utility. Our actions here are also receiving external recognition: At our production facility in Kunshan, China, one production building and the new Training Center are certified to the LEED Gold Standard. As part of our energy audits to implement the EU Energy Efficiency Directive, in the reporting period we additionally examined the building shells of our German and relevant European locations and analyzed them to identify options to improve their energy efficiency.

             

            GHG emissions: GHG emissions recording methodology

            We calculate our greenhouse gas emissions by energy source and based on specific CO2e factors. We derive these from a database as CO2 equivalents. Where possible, we use the specific CO2e emission values of the respective local or regional electricity utility. Recording emissions as CO2 equivalents based on conversion factors also allows us to factor in the emission of other greenhouse gases such as CH4, N2O, HCF, PFC, and SF6. Process-based and volatile emissions with a significant greenhouse gas potential are only found in refrigerants. As emissions of these can only be identified during maintenance measures, which are usually performed by external specialist companies, global recording of their volumes has been hampered so far by several inaccuracies. Furthermore, beyond determining R11 equivalents, up to now we have refrained from calculating them, as conservative assessments put our expected annual greenhouse gas potential at less than 2% of our emissions under Scope 1 and 2.

            Business trips

            Wherever possible we avoid taking unnecessary business trips, which is why we are increasingly using video and telephone conferencing in our global organization to save on travel expenses and allow speedy coordination. Our use of these means of communication, and their spread across our Group, increased significantly in the reporting period.

            Furthermore, every quote provided by our travel agency partner automatically shows the CO2e emissions generated by a particular means of transport, providing transparency to Voith travelers when choosing their means of transport in terms of CO2e emissions.

            In addition we predominantly lease the vehicles in our vehicle fleet, and we replace them every three years by the next generation of lower-emission vehicle. We are already using electric vehicles at our location in St. Georgen (Austria); for the current fiscal year, we plan to construct an electric charging station and use several electric vehicles at our Heidenheim location.

            Logistics

            Our transport-related CO2e emissions – caused mainly by our external logistics service providers – fell year on year by 21% to 28,755 t (previous year: 36,575 t). This fall was thanks mainly to a considerable drop in CO2e emissions from airfreight.

            As part of our Group-wide program to improve operational excellence, we are also working on shortening delivery times and optimizing delivery costs.

            Regarding production-related air pollutants, we predominantly release volatile organic compounds (VOCs) and dust produced as a direct result of our manufacturing processes. When recording and calculating these emissions we are guided by the regulations of the country in question and associated requirements, such as the VOC Directive within the European Union.

            Coating processes (resins for generator production and roll coating), lacquering processes, and cleaning processes (particularly surface cleaning) account for roughly a third each of our production-related VOC emissions.

            Non-methane VOCs (NMVOCs) once again accounted for the greatest share of our production-related air pollutants in the reporting period at 69 t (previous year: 70 t). This is followed by dust emissions at 17 t (previous year: 17 t), generated mainly by our foundry in São Paulo, Brazil. The year-on-year drop is due to the lower production volume at the location. Furthermore, dust emissions fell, as forecast the previous year, as gray cast iron production was discontinued and foundry activities were focused on stainless-steel casting.

            We work tirelessly to further reduce our emissions of pollutants. Among our activities in this area, during the current fiscal year we introduced to our Kunshan location the butanone treatment process, which we had successfully tried and tested at our Wimpassing facility.

              Voith employs country-specific recycling factors to calculate the proportion of secondary raw materials in terms of the overall amount of materials used. The lower share compared to the previous year of secondary raw materials in terms of the overall amount of materials used is due to regional changes in materials procurement, whereby the recycling factors used have changed.

              Specific waste

              In the reporting period numerous Voith locations also developed specific solutions to local waste challenges. Voith considers the most significant measures for this reporting year to include:

              • Commencement of reconditioning non-recyclable Euro-pallets at our location in Heidenheim resulted in waste wood savings of 53 t.
              • Improvement of process stabilities at our location in Summerville resulted in waste savings of roughly 44 t.
              • Optimization of the tank size at our location of Liaovang resulted in waste emulsion savings of approx. 10 t.
              • Delivery of semifinished products between our locations of Appleton and Wilson using recycled wooden boxes instead of disposable cardboard boxes.
              • Delivery of sieve heads in modular transport boxes across several supply-chain stages up until dispatch to the customer resulted in packaging cost savings of up to 30% at our Heidenheim location.

              The collection of hazardous waste at Voith is governed by internal regulations. Only qualified specialist waste disposal companies that adhere strictly to our regulations are permitted to dispose of our waste. Any violations are rigorously pursued and lead to the termination of the business relationship. To check this, we regularly audit the waste disposal companies we use. The scope of these audits includes inspections of the waste disposal companies’ sites and related plants, as well as the collection and documentation of proof of disposal.
              Owing to the variety of standardization topics as part of last year’s restructuring of our HSE organization, this topic was moved to the current fiscal year.
