Environmental protection & sustainability

Part galvanisation is verifiably the most sustainable and environmentally-friendly corrosion protection system with protection durations of up to 100 years (DIN EN ISO 14713). In comparison to conventional coating systems or paint coatings, hot-dip galvanising saves up to 3 times more energy and resources. The ultra-modern systems at the Heek, Stadtlohn and Sulz plants minimise the energy consumption and therefore also the environmental pollution. Treatment plants, closed materials cycles and ultra-modern filter technology are the guarantee for optimum and efficient energy utilisation and resource economisation. The Lichtgitter galvanising plants are justifiably proud of the positive environmental balance which is verified through regular emission measurements and environmental inspections through the approval authorities.

A research project on the "Reduction of the use of zinc during hot-dip galvanisations through the combination of a new fluxing agents with an innovative fluxing agent treatment plant" was supported in the year 2010 through the Federal Ministry for the Environmental, Nature Conservation and Nuclear Safety. The knowledge gained was consistently implemented in the other galvanising plants within the Group. In this way, a substantial proportion of CO2 emissions are saved at the Heek, Stadtlohn and Sulz galvanising plants.

Openness regarding environmental data has always been the path taken by the Lichtgitter Group galvanising plants. From this, for example, results a Type 3 Declaration acc. ISO 14025 and EN 15804. The environmental product declaration for hot-dip galvanised construction steels accords with the international standards for environmental accounting.

We realise environmentally-friendly production for you through the following measures:

We save on natural gas through the consistent use of the hot furnace exhaust gases to heat the preliminary treatment baths. At the same time we save CO2 emissions totalling 1,000 t per year in comparison to conventional galvanising furnaces. The degree of energy utilisation in our galvanising plants lies at up to 96 percent.

The emission-relevant steps in our galvanising plants have been interlinked and enclosed and kept under permanent negative pressure. This is the best possible way to protect the environment against emissions.

We continuously regenerate the fluxing agent used during the preliminary treatment for galvanisation. In this way, we keep the quality of the fluxing agent at a consistently high level and avoid hazardous goods transportation for the treatment of the fluxing agent.
