Committed to future generations as a family business

At Wuppermann, we understand sustainability to be a form of ecological and economic action that ensures comparable or better living conditions for present and future generations. As a family-owned company with a long tradition, we feel an obligation to future generations and set ourselves ambitious and concrete goals in climate protection: The production process for the Wuppermann Group is to be 100% CO2 neutral by 2027.

Photovoltaics at Wuppermann

Wuppermann has been generating electricity from photovoltaic systems at all five production sites and at the Group's headquarters in Leverkusen since October 2023. The installed nominal output is over 4,500 kWp and covers up to 5% of the Group's annual electricity requirements.

Power generated to date:
1,892 MWh

Period: 2024, Performance data: All locations

Heat-to-coat process from Wuppermann saves up to 54% CO2

In an investigation with the Fraunhofer UMSICHT Institute, it was possible to determine: The galvanizing process including post-treatment and zinc causes 0.080 t CO2-eq./t at the Moerdijk site in the Netherlands (WSN). The reference process causes CO2 emissions of 0.173 t CO2-eq./t. This now results in a CO2 saving of 54%. The Judenburg site in Austria (WA) produces 0.089 t CO2-eq./t CO2 emissions, which corresponds to an advantage of 49 %. At the Győr site in Hungary (WH), CO2 emissions amount to 0.116 t CO2-eq./t, which corresponds to an advantage of 33 %. This includes the emissions from the production of the zinc and electricity consumed. The environmental impact of the hot strip input material is not included in this calculation.

Energy efficiency and recycling in steel processing

Energy efficiency is the result of many smaller and larger measures. Therefore, energy efficiency measures are continuously developed and implemented as part of a continuous improvement process (CIP). The energy requirement in relation to the production volume is to be continuously reduced in this way. As a rule, these measures lead not only to a reduction in costs, but also to a reduction in CO2 emissions.

Raw materials such as ore, steel and zinc are scarce resources that are extracted at great expense. It is therefore all the more important to use these resources sparingly and to return them to the material cycle. It helps that steel is 100% recyclable. But we also keep an eye on all process-relevant raw materials, consumables and supplies. Our goal is to ensure that all materials that are not delivered to our customers as products are completely recycled. Today, this recycling rate is already over 99 % at the two large galvanizing sites. The remaining waste is systematically examined and should become recyclable as quickly as possible.

CO2-neutral production 2025

Wuppermann produces about one million tonnes of strip galvanized steel a year using the so-called "heat-to-coat" process. The Fraunhofer Institute has proven in 2022 that this process saves more than 54 percent of CO2 compared to conventional galvanizing processes based on fossil fuels. The usual cold strip galvanizing processes require the steel strip to be annealed to a temperature of 750° C in a large annealing furnace fired with natural gas or metallurgical gas. Its combustion product is CO2, which is released into the atmosphere. The strip then has to be cooled down to the galvanizing temperature. Wuppermann's heat-to-coat process uses a small, inductively - i.e. electrically - heated strip heating furnace that heats the steel strip to the galvanizing temperature of 460 - 480° C in seconds. With electricity as the main energy source, the electricity mix is the main lever for CO2-neutral production. Consequently, for our ambitious goal, we are gradually changing our electricity mix to purchase from renewable energy sources. The first measures have already been implemented. For example, since the beginning of 2021, the company has been sourcing exclusively green electricity at its production sites in Austria. The Dutch site in Moerdijk is switching completely to electricity from wind power in 2022. In 2022, photovoltaic plants were available for own electricity generation at the Györ site in Hungary and the Altmünster and Judenburg sites in Austria. These three plants generated about 2.5 GWh of electricity. In the meantime, all five production sites have their own photovoltaic system in operation.

CO2 neutral group

As the majority of all emissions are directly linked to production processes, this is the clear priority of our climate protection activities. In addition, Wuppermann's business activities generate further emissions that we will systematically record and consistently reduce by 2030, so that the entire Wuppermann Group will be CO2 neutral by the end of this decade.
