Materiality and stakeholder management

Sustainability is a joint project, which is why we involve all key stakeholders.

Which topics are material for Interzero's sustainability reporting? We answer this question engaging in dialogue with our stakeholders. In 2017, Interzero conducted a comprehensive materiality analysis based on the Sustainable Development Goals (SDGs). At the end of 2022, we started another analysis in line with the requirements of the Corporate Sustainability Reporting Directive (CSRD). The results will form the basis for our next reports.

GRI 2: General Disclosures

GRI 2-28 – Membership associations

As an environmental services provider, Interzero wants to act as an ambassador for sustainable development and to take an active part in shaping debate as a member of selected associations and advocacy groups by continuously expanding its involvement in sharing knowledge on the circular economy.

The Federation of the German Waste, Water and Raw Materials Management Industry (BDE e. V.), with Markus Müller-Drexel, CEO Interseroh+, serving as its Vice Chairman, is the industry association for the circular and resource economy. It is by far the most important association for Interzero. Numerous employees are represented in a total of 21 of the association's working groups – on a wide range of topics including climate and energy policy, electrical recycling and hazardous goods.

Interzero also supports the German DIY, Building and Horticultural Trade Association BHB with sponsorships and presentations. This work involves identifying and promoting new approaches for the building trade (for example recycled plastics and returnable pooling for building goods pallets).

Interzero has also been a member of the German Packaging Institute (dvi) since 2016. The organisation promotes knowledge transfer and dialogue between industry companies, institutions and partners. Here, Interzero contributes its expertise on the topic of packaging optimised for recycling – for example as part of the joint Future Resources event series. This series took place for the sixth time in a row in November 2022. Next year's event is already being planned.

The non-profit foundation KlimaWirtschaft is another key Interzero partner. Its mission is to actively shape and advance the shift to climate neutrality. Comprising CEOs, managing directors and family businesses, the initiative actively campaigns for compliance with German and European climate targets by connecting relevant actors and approaching politicians with tangible proposals. Within this foundation, Interzero works together with other supporting companies in ‘transformation alliances’ on climate neutrality to develop scalable solutions along value chains.

Interzero’s dual system, Interseroh+, is also involved in “Mülltrennung wirkt” (Waste Separation Works!), a campaign created by dual systems. As an active member, Interseroh+ educates on the importance of recycling and proper waste separation to raise awareness and empower consumers to separate waste properly on the campaign's website. Interseroh+ is also actively involved in Forum Rezyklat. It connects stakeholders from all parts of the circular economy, designs packaging to be recycling-friendly from the outset and uses more recycled material in packaging. Interseroh+ contributes its expertise in all areas and is also active with its management in the steering team. Memberships are also maintained in a variety of initiatives in the world of plastics, such as the Polyolefin Circular Economy Platform (PCEP), PETCore and Kunststoffland NRW e. V.

Interzero Circular Solutions Germany GmbH is a member of the United Against Waste e. V. association (unitedagainst-waste). The association promotes the sustainable management of food resources in the catering industry.

Markus Müller-Drexel, Managing Director at Interseroh+ GmbH, chairs the Central Committee on Environmental Protection at the Bonn/Rhein-Sieg and Cologne Chambers of Industry and Commerce (IHK). Interzero is also active in the Building Sector and Environmental/Machine Technology Association (VDBUM) and is a solution provider for Deposits and Pooling at GS1 Germany (GS1). Furthermore, Interzero is a partner and promoter of Markenverband e. V. (Markenverband), which represents the interests of branded businesses in Germany.

GRI 2-29 – Approach to stakeholder engagement

One goal of Interzero’s sustainability strategy is to talk regularly with stakeholders about various topics of relevance to sustainability. Interzero not only sees its role as being a strong advocate for the development of the economy towards a circular model, but also seeks to develop new, resource-friendly solutions that are capable of supporting a sustainable future.

Accordingly, it is essential to know the needs, requirements and interests of the company’s key stakeholder groups. These include in particular customers and potential customers, researchers, suppliers, employees and experts working in the field of sustainability.

The following stakeholder groups are particularly important for Interzero:

  • Customers and potential customers
  • Science and research
  • Suppliers
  • Employees
  • Experts from the sustainability sector
  • (New) talent

Stakeholders were identified as part of preparing Interzero’s sustainability strategy. This selection is reviewed regularly, most recently in 2022. The selection was confirmed and a further stakeholder group was added: (new) talent.

Interzero works through a variety of interest groups and associations (see GRI 2-28) to actively shape the trend towards a closed-loop economy. We also regularly engage in interchange with other environmental services providers, suppliers and partners in the circular economy.

Interzero provides its customers with insights into circular economy principles at workshops and through the Academy (an online platform for knowledge transfer). Here, both sides work to develop ideas about how customers can manage their products and materials in a closed loop. Its range of virtual seminars covers topics such as packaging optimisation, circular economy, sorting technology and battery recycling. Customers and other interested stakeholders are also invited to participate in the annual "Future Resources" series of events held in partnership with the German Packaging Institute (dvi). Interzero has set itself the goal of further intensifying its dialogue with customers via its social media channels, for example.

Interzero uses audits to engage with suppliers at regular intervals.

Interzero primarily informs its employees via the intranet (Interzero Net) and by email (Interzero News and Interzero Note). Information is also shared via the Microsoft Teams app and a bi-annual staff magazine called Circle. Interzero is currently pushing ahead with building its internal communication structure, which will offer additional information channels in the future. Interzero also holds all-hands meetings called Interzero Meet, at which, for example, the company announces significant strategic decisions and provides information about relevant group topics. Employees can ask the management direct questions and raise their issues at these events. Interzero Meet has been held as a hybrid event since 2022, allowing colleagues from all entities and locations and those working from home to participate. This exchange is supplemented by quarterly digital CEO Updates. 

Interzero uses annual employee appraisals as another means of exchanging information with employees and also carries out software-based employee satisfaction surveys (see also GRI 401). We also have a survey tool for employees, which can be used to obtain opinions on various topics.

GRI 3: Material topics

GRI 3-1 – Process to determine material topics

In 2017, Interzero conducted a comprehensive materiality analysis based on the Sustainable Development Goals (SDGs). The process was described in detail on p. 21/22 of our 2018 Sustainability Report. The resulting materiality matrix was reviewed in 2020 to take account of recent developments in society and the company. The results of this process can be found on pages 23 and 24 of the 2020 Sustainability Report. Despite the changes in the ratings, there was no change in the choice of essential topics and their GRI categories (see GRI 3-2). The material topics serve as the basis for our sustainability reporting.

At the end of 2022, Interzero also started conducting a materiality analysis based on the requirements of the Corporate Sustainability Reporting Directive (CSRD). The results of this analysis were adopted and approved in the first quarter of 2023. All material topics will serve as the foundation for the next sustainability report.
