Donau Carbon Frankfurt: greater energy efficiency with ISO 50001

Energy efficiency is a key factor in competitiveness today and is one of the cornerstones of sustainable corporate management. At its Frankfurt site, Donau Carbon has created a systematic framework for resource conservation, cost reduction, and climate protection with the introduction of the internationally recognized ISO 50001 energy management system.

Significance of ISO 50001 for Donau Carbon Frankfurt

The Frankfurt site is an important center of expertise for activated carbon and specific adsorption solutions. The portfolio ranges from the reactivation of used activated carbon to customer-specific treatment processes, all of which have high energy requirements.

ISO 50001 provides us with the necessary tools to transparently record these energy flows, systematically identify potential savings, and implement continuous improvements.

Advantages of ISO 50001 at the Frankfurt site:

• Sustainable cost reduction through targeted efficiency measures

• Reduced CO₂ emissions as a contribution to our customers' climate targets

• Legal certainty and funding opportunities through compliance with all relevant regulations

• Strengthened market position because we demonstrably practice sustainable production

Starting point: Systematic recording of energy consumption

At the beginning of the project, all energy flows at the Frankfurt site were comprehensively analyzed. Key steps in this process included:

• Definition of energy performance indicators (EnPI) that accurately reflect energy use in production, reactivation, and building technology.

• Expansion of the meter and measurement infrastructure to seamlessly record all relevant consumption data.

• Creation of a legal register documenting all legal requirements and available subsidy programs.

This establishes an energy management system that enables transparent control of energy use and promotes long-term efficiency gains.

Energy policy: Putting analysis into practice

Based on the analysis, energy policy measures were developed for the Frankfurt site, focusing on the following areas:

• Frankfurt energy management team: An interdisciplinary team from the technology, production, purchasing, and controlling departments works closely together and manages activities.

• Employee training: Raising awareness of energy-efficient behavior among all employees—from machine operators to administrative staff.

• Continuous improvement: Regular audits and management reviews ensure that the goals set are achieved and further developed.

• Energy management in accordance with ISO 50001 follows the PDCA cycle (Plan-Do-Check-Act), whereby energy-related activities are systematically planned, implemented, reviewed, and adjusted.

To anchor this approach company-wide, the principles and processes of energy management are laid down in a cross-location management manual for the Donau Chemie Group and are continuously updated there.

PDCA cycle

First measurable results at the Frankfurt site

• Significant successes were already achieved in Frankfurt in the first year, including:

• Optimized heat recovery in activated carbon reactivation

• Conversion to LED lighting in production and administration

• Intelligent load management to avoid power peaks

• Reduction in specific gas consumption by 3.5 percent compared to the previous year

These measures enabled us to significantly reduce energy consumption and CO₂ emissions while achieving measurable cost savings.

Outlook: Continuous optimization of energy efficiency

For Donau Carbon Frankfurt, ISO 50001 certification is not an end point, but the beginning of a continuous optimization process. New technologies, increasing customer requirements, and ambitious climate targets encourage us to continuously develop our energy management. This enables us to remain a reliable and sustainable partner for customers worldwide in the long term.

Conclusion: ISO 50001 at the Frankfurt site

The successful implementation of ISO 50001 at the Frankfurt site illustrates how systematic control of energy use can go hand in hand with economic efficiency and ecological responsibility. Our energy management system creates the basis for conserving resources, reducing costs, and improving our carbon footprint in the long term—a win for our customers, our employees, and the environment.
