Our environmental management
Our production is energy- and resource-intensive. Both through the consumption of natural resources and the use of various chemicals, the topic of environmental protection enjoys a high priority for us.
INDICATORS

With our environmental management system in accordance with the European standard EMAS, we pursue a holistic approach to the topic of the environment.
Developed by the European Community, EMAS covers all relevant environmental aspects. It is also performance-focused: Every certified company should continuously improve its environmental performance – and involve its employees in the process. “EMAS-certified companies make an effective contribution to environmental protection, save costs and show social responsibility. EMAS ensures that all environmental aspects from energy consumption to waste are implemented in a legally secure and transparent manner.” (www.emas.de)

Environmental reporting
As an EMAS-registered and certified company, we are obliged to publish a detailed environmental statement annually. The environmental statement is validated by an environmental appraiser and is an essential part of our environmental management system.
The most important key figures and information can be found on this sustainability page. Our validated environmental statements are available for download here:

OEKO-TEX® STeP
In addition, we have also been certified according to the OEKO-TEX® STeP standard since 2020. This means that the systemic requirements of EMAS are supplemented by content requirements from the OEKO-TEX® STeP standard. This standard contains six different modules: Chemicals Management, Environmental Performance, Environmental Management, Social Responsibility, Quality Management and Health & Safety.

Our environmental aspects
Environmental aspects are all activities, products or services of a company that have an impact on the environment. The identification of direct and indirect environmental aspects is an essential part of any environmental management system. These aspects are recorded, evaluated and reviewed at regular intervals.
Energy and water management

Resource consumption depends on various factors, for example, the grammage and composition of the fabric, colour and finishing requirements, or even batch size. A multitude of product variants, therefore, also stands for a multitude of consumption profiles. For this reason, even a comparison with oneself becomes a challenge. Looking at our production profile is, therefore, essential for interpreting the key figures.

A lot of steam is needed in the dyeing and finishing process. Therefore, our production is energy intensive. The high consumption of energy and water is one of the most important environmental aspects and thus energy and water management is a very important part of the environmental management system. Consumption data are evaluated on a monthly basis — key figures support this evaluation and indicate irregularities at an early stage.

“We cover almost 99 % of our water needs with treated well water.”
“Various measures to improve energy efficiency in the last fiscal year will save about 480,000 kWh of energy annually in the future.”
Wastewater management

Wastewater management is an important element in our environmental management system. Given the high level of water consumption, wastewater is also the result of production. Compliance with legal requirements from the Wastewater Ordinance is ensured by the daily controlling and checking of the mixing and equalisation basin by trained staff. In addition, there are regular and independent inspections conducted by the responsible monitoring authorities and contracted service providers.

Waste management

Waste is recovered or recycled by authorised and qualified waste disposal companies. Waste types and quantities are recorded in a waste register. In addition to the typical waste types – such as paper, municipal waste or even film – “textile-specific” waste types such as residual solutions, sludge or textile waste are also generated.
Waste summary
2018/2019 | 2019/2020 | 2020/2021 | |
---|---|---|---|
Total waste | 305 T | 399 T | 353 T |
Hazardous waste | 0.25 T | 0.8 T | 2.2 T |
Hazardous waste per output | 0.027 g/m | 0.08 g/m | 0.22 g/m |
Direct textile recycling
In the production process, textile “waste” accumulates at various points, for example, as offcuts, or in sample production. These remnants are sold directly to a textile recycling company and are, therefore, not officially declared as waste.

Biodiversity

As a manufacturing company, we depend on an intact ecosystem and on biodiversity, because the use of natural resources (e.g. water) and raw materials (e.g. cotton) is essential for our production processes.
When the company was relocated from the city centre to an industrial site in 1982, part of the forest area was preserved when the company premises were planned. This area of nature on the border to the neighbouring farm is largely left to its own devices. The small forest is home to deer, rabbits, squirrels and various bird species, among others.
On a roof terrace renovated in 2017, the insect-friendly greenery also attracts various butterflies, bees and wasps – from spring through to autumn. Both areas count as “near-natural areas” according to the EMAS definition and serve nature as both a retreat and habitat. The remaining open areas are mainly bushes, shrubs and lawns.
“Germany has committed itself to the protection of biological diversity through both the Convention on Biological Diversity and the Sustainable Development Goals (UN Sustainable Development Goals). This issue is also an important component of environmental protection for German companies.”

Our Kettelhack forest grows by exactly one tree per employee per month!
Since 2018, we have supported the Plant-for-the-Planet project. On behalf of Kettelhack, one tree per employee is planted every month in Campeche (Mexico). As a foundation, the organisation has taken over its own plantation area comprising almost 14,000 hectares of fallow land there, and is reforesting this area with various native tree species. These trees not only store carbon, but also promote local biodiversity. Through our contribution, 1,200 new trees are added every year.
