Environmental management system
In March 2014, the certification body DNV confirmed that the DEUTZ AG environmental management system conforms to the international norm DIN EN ISO 14001. The audit that preceded this verdict was carried out over several days by a team put together by DNV to assess the Company’s management systems for quality, environmental aspects and energy.
In 2014, all departments initiated measures to create an ‘Integrated DEUTZ Management System’ from the aforementioned management systems. This will generate synergies that result from similarities in how the management systems are structured.
Further improved figures for air purity
In 2014, we made significant reductions in the main types of emission generated by our production processes, including nitrogen oxide, carbon dioxide and benzene. This is a result of the ongoing improvements to the DEUTZ exhaust aftertreatment systems.1)
Reducing the length of time that diesel engines spend in testing has also played a key role in lowering emissions. Leaner test programmes, rigorous standardisation of test rig technology and changes to processes in the preparation of engine tests have cut the testing time for diesel engines with capacities of less than four litres by around four minutes and for diesel engines with capacities of above four litres by around 1.5 minutes compared with 2013. The ongoing reduction of test times is especially important for DEUTZ because the regulated test areas in Cologne account for the highest proportion of emissions in the Company. This approach is also particularly effective from an economic and environmental perspective as it not only lowers emissions but also saves resources.
In 2014, for example, 563,000 litres of fuel were used to test compact engines in the test area at the Cologne-Porz production site (2013: 689,000 litres). This equates to a fuel saving of 18 per cent, even though the number of engines tested rose in comparison with 2013.
By introducing the energy management system and by optimising operating times, which was mainly done in the fourth quarter due to the production programme, we were able to reduce carbon dioxide emissions resulting from product-manufacturing processes by 13.5 per cent on the previous year (2014: 360kg/engine; 2013: 416kg/engine). The significant drop in CO2 emissions in comparison with 2013 was primarily due to the production sites in Germany and Spain lowering their consumption of district heating, natural gas and electricity.
Focus on water protection measures
In a research and development initiative, the equipment at the testing centre that has to meet water pollution regulations was brought up to date with the latest technology. In the final phase, completed in 2014, the areas subject to the provisions of the German Water Resources Act were upgraded and the pipes used to transport and collect waste materials were replaced. Just under €0.2 million was invested in these measures. In addition, an independent expert conducted an extensive check of all underground pipes of tank facilities at the site in Cologne. No defects were found. On this basis, we do not currently expect any disruptions that would affect the availability of the facilities and which in a worst-case scenario could lead to contamination of the soil and groundwater.
Waste disposal and handling of hazardous waste
A successful waste disposal system begins with the avoidance of non-reusable packaging. Because making an engine requires such a large number of components to be supplied by such a large number of providers, we need to conduct regular checks to ensure that reusable packaging is being used in preference to non-reusable packaging in the production cycle. Such packaging can only be used if our high quality standards and transport methods allow it. In 2014, DEUTZ invested €1.1 million in the sourcing of reusable packaging. Hazardous and non-hazardous waste from production and manufacturing is only disposed of by companies that are certified to do so under the requirements set out in the Ordinance on Specialised Waste Management Companies (EfbV). The DEUTZ AG safety department carries out spot checks on the companies contracted by us to remove and transport waste. No cases of non-compliance with the statutory norms have thus far been found.
