The Birthplace of Isophorone Chemistry and a Site Driving Process Transformation

In 1962, our Herne site in Germany became the birthplace of isophorone chemistry. Today, the site continues to play an important role in the development and implementation of projects aimed at improving energy efficiency, reducing emissions, and advancing production technologies.

As part of Evonik's climate and sustainability strategy, the "Herne Green Deal" brings together initiatives designed to reduce the site's greenhouse gas emissions and increase the use of alternative energy and raw material sources. These activities support the long-term ambition of reducing dependence on fossil fuels and fossil-based raw materials in production processes.

Join us as we continue to invest in technologies and infrastructure that support the ongoing transformation of chemical manufacturing.

Evonik's Approach to Climate and Resource Efficiency

At Evonik, we work with customers across a range of industries to develop products and solutions that can support their environmental and operational objectives. These efforts focus on areas such as emissions reduction, circular material flows, resource efficiency, and responsible use of raw materials.

As part of our goal of achieving climate neutrality across the Group, Evonik plans to invest €700 million in production processes and infrastructure by 2030. These investments are intended to support improvements in energy efficiency, resource utilization, and emissions reduction across selected operations.

A key element of these efforts is the ongoing development of our Herne Crosslinkers site. Various projects are focused on reducing reliance on fossil-based resources and increasing the use of alternative energy and feedstock sources where technically and economically feasible.

This includes the production of our eCO product portfolio, which incorporates renewable raw materials using recognized certification and allocation approaches where applicable.

Through the projects grouped under the "Herne Green Deal," Evonik is pursuing the long-term objective of reducing the site's reliance on fossil fuels and fossil-based raw materials while supporting operational efficiency and emissions reduction efforts. A key focus of this initiative is the transformation of our Herne Crosslinkers site, where we are dedicated to delivering more sustainable production by minimizing reliance on fossil-based resources. The green energy transition at Herne includes the production of our eCO series of products, which utilize renewable raw materials.

With the holistic approach of the "Herne Green Deal," our long-term ambition is to make the plant entirely independent of fossil fuels and fossil-based raw materials. By achieving this goal, the Herne site aims to become a shining example of sustainable production not only for Evonik but also for the global chemical industry as a whole.

Our District Heating Project

The Technical Options for Thermal Energy Recovery (TORTE) project captures waste heat generated during isophorone production in Herne and makes it available for use in the district heating network serving homes in Gelsenkirchen. The project has the potential to provide recovered thermal energy to up to 1,000 households in the Ruhr region and demonstrates how industrial waste heat can be integrated into local energy infrastructure. 

The project is part of the Herne Green Deal at Evonik's Herne site, which operates 17 production plants across approximately 250,000 square meters. One key initiative focuses on recovering heat that would otherwise be released through cooling towers and supplying it to the district heating network. This approach supports improved energy utilization and contributes to emissions reduction. Read more...

In recognition of its innovative approach, the TORTE project received the "Responsible Care Initiative" award from the German Chemical Industry Association in 2023.  Learn more about the Responsible Care Award

From Waste Heat to Heating Homes: Technical Options for Thermal Energy Recovery

Evonik's Herne site uses a heat pump system to transfer industrial waste heat from cooling towers into the regional district heating network.

Advancing Hydrogen Technology for Production

Our H₂annibal project, developed in collaboration with Siemens Energy, uses electrolysis technology to produce hydrogen from renewable electricity for applications at the Herne site. Launched in 2022 and funded by the German Federal Ministry of Education and Research, the pilot project is expected to supply up to 45% of the site's hydrogen demand and 100% of its oxygen demand.

The 8 MW PEM (proton exchange membrane) electrolyzer could avoid approximately 12,000 metric tons of CO₂ emissions annually compared with conventional hydrogen production methods. The project supports the integration of hydrogen technologies into industrial processes and reflects Evonik's continued investment in technology development and operational innovation. Read more...
