Additional projects and continuous improvement in 2025/26
LIGHTING SEGMENTS
COMPONENT SEGMENTS
Waste management governed by local waste management policies at the production sites forms a key component of the environmental management systems, meets the necessary legal obligations and aims to continually reduce waste. Each production site has appointed a waste officer, follows documented processes and makes detailed records required by law for all waste generated and its transportation. The metrics for waste contain the waste generated in tonnes and are split into the categories of recycled waste, residual waste and hazardous waste. Dornbirn (AT): At the lighting plant, the existing waste management scheme for the office areas has been further improved and rolled out across all offices. This had two positive effects: on the one hand, waste sorting has been optimised, and on the other, the waste bins located centrally in the offices have reduced the physical strain on the cleaning staff. A material flow management system has been introduced in production to track and reduce waste of recyclable materials throughout the entire process chain. This has improved transparency and material utilisation rates. In addition, the purchase and commissioning of a strip welding machine has significantly reduced the amount of scrap generated during coil changes. Up to 200 kg of scrap has been avoided here each day as a result. A return scheme for single-use returnable bottles has been introduced at both the lighting plant and the components plant. This ensures that single-use drinking bottles are collected in a targeted manner and sent for recycling. Lemgo (DE): Waste separation has also been improved in the offices at the Lemgo site through a number of new initiatives. Niš (RS): At the lighting plant, the material utilisation rate has been improved through the opti- mised use of sheet metal blanks in metalworking. Waste is minimised to the greatest possible extent when creating CNC programmes by arranging different components on a single blank. This approach allowed 5,021 kg of material to be used efficiently. At the components plant, was- te management was optimised through the classification of a waste stream that had previously been considered non-recyclable as recyclable. This waste component is now channelled into the recycling stream, thereby securing a further source of raw materials. Shenzhen (CN): Over the past financial year, a reduction of 1.14 tonnes of hazardous waste has been achieved. A newly appointed supplier takes back the packaging containers for silico- nes for reuse and/or recycling, which means these no longer need to be disposed of at great expense. Spennymoor (UK): At the lighting plant, the volume of hazardous waste has been reduced through the introducti- on of an additional evaporation process during the pre-treatment stage of the coating process. This process separates the components; the purified water is reused in the pre-treatment stage, and only the residual materials are disposed of. At the same time, shredding and re-gra- nulation have made it possible to significantly reduce the volume of polycarbonate waste. The recycled material is then reused. At the components plant in the UK, the recycling rate has improved significantly over the past three years (from 74% to over 92%). This has been achieved by ensuring that materials that were previously disposed of as general waste are now treated as recyclable materials (inclu- ding PCB panels and SMD waste). Suppliers were also involved in optimising the packaging.
