Immense sustainability potential for production companies
EVVA uses a large amount of materials for locking cylinder and key production, particularly brass, nickel silver, cardboard, oils, emulsions, key punchings, etc. The potential for recycling and resource conservation is accordingly diverse – and so are the positive effects on the environment. Sustainable handling of materials has therefore been defined as a key topic for EVVA in the stakeholder dialogue.
The reported measurement data was published in EVVA environmental reports and in the energy audit. These are externally audited and confirmed by authorities (e.g. environmental agency, waste management agency, trade authority, representatives of the Chamber of Labour and the Chamber of Commerce) and by sustainability consultants.
All input/output analyses from 2015 to 2019 (2020 will only be available at the end of 2021) with the most important materials required for EVVA to manufacture access systems, can be found in the following pdfs. Of these, wood, cardboard, paper and packaging are renewable materials. We also include brass and nickel silver, as all metal chips generated during processing are fully recycled (see Recycling Materials for more information).

The most important materials for EVVA
Efficient use of materials
Brass is our main manufacturing material. Brass accounts for about 85% of the total metal used. Brass demand at the headquarters increased by 10% to 1.6 million tonnes from 2015 to 2019. However, production output increased by 14.5% in the same period, which speaks for an efficient use of materials. Reason for this: With better production processes, EVVA was able to greatly reduce brass scrap and waste – just as the increased use of Clean Production machines reduced the need for oil. EVVA has already achieved a number of successes in terms of waste prevention, but much remains to be done. Read more about waste.
