Numerous measures for greater environmental protection
The measures of the Doors Division for increasing efficiency are reviewed and ensured by a consistent energy management. At the Deggendorf site, all consumption is called up in real time with a state-of-the-art energy management system. An automated reporting system makes it possible to take countermeasures when defined limit values are exceeded. An annual budget is available for measures to increase efficiency. In addition, a majority of the companies regularly carry out certification audits according to the standards ISO 9001, 14001, and 50001. Energy efficiency is an important factor especially in the modernisation of production lines and peripheral systems because it allows significant reductions in power consumption. Further investments in reducing power consumption concern entrance gates, a planned hall roof with new insulation, as well as a photovoltaic system, LED lighting, and the replacement of a filter system. Of course, attention is also paid to the use of energy-saving technology in new buildings and renovations at the operating sites. In addition, a project for energy efficiency analysis is being carried out from which new measures will be derived.
And the degree of self-sufficiency will ultimately be continually increased through the construction of new or the expansion of existing energy generation systems. At the Prüm doors plant, residual materials from production are used to generate heat and electricity: The 30-year-old CHP system there has reached the end of its life cycle and is currently being replaced by a more modern and more efficient system. The new CHP system, which will be commissioned in 2023, can produce more than double the amount of electricity from biomass waste as the old system. This means that the Weinsheim (D) site will be able to generate up to 60% of the power requirements internally. The Garant production plant in Amt Wachsenburg (D) will take a similar path: In 2021, the planning phase started for a state-of-the-art CHP system, which will commence operations in 2024. Likewise, this system will also cover around 50% of the power requirements of the production plant.
In addition to the above-mentioned objectives, the division is also optimising its production processes – as for example with the implementation of shop floor management at various sites. Furthermore, packaging material will no longer contain any foils whatsoever in the future. This will save 60 t of packaging foil as well as additionally 280 m³ of gas per year by dispensing with a foil shrink machine.
