CSR & Environment at Tag Copenhagen
At TAG Copenhagen, corporate social responsibility (CSR) and environmental stewardship are integral to our business practices. Our commitment to sustainability and social responsibility is reflected in various areas of our operations.

- PVC-Free Materials: We are committed to eliminating PVC from our processes. All plastic used in our daily production, as well as packaging materials like tubes, caps, plastic bags, and envelopes, are certified PVC-free through our trusted providers.
- Recycling Efforts: We actively support recycling by collecting used materials such as bottles, cardboard, plastic, and paper. All recyclable items are processed to reduce waste and promote a circular economy.
