Our vans are electric cars. We avoid additional transport routes through detailed logistics planning. Our suppliers are based in the region and have fixed delivery days and routes for efficient and emission-reducing delivery of products.


We only use crockery and cutlery that can be reused. We do not use straws for drinks and cocktails, but we are happy to offer our guests recycled paper straws with their drinks on request. All our table linen is made of fabric and is laundered at a local laundry.


Our waste is strictly separated. Drinks for our guests are served in glass bottles, which are refilled by the producers after use. Food waste is disposed of in organic waste and processed into biogas. Cardboard and paper are separated and collected by the city. We only use coffee beans to prepare our coffee drinks. We use the coffee grounds to fertilise our herb garden.


Thanks to detailed planning and prompt communication of the number of guests, we can minimise food waste and calculate portion sizes appropriately. Our catering waste is reused for the production of sauces and stocks. Food that is left over at the events is offered to the organisers and guests to take away. Here we ensure that hygiene regulations are observed. Our employees always have the option of taking home dishes that have been produced in excess.


As our offices have plenty of natural light, the lights are only switched on when necessary. Our electronic devices are switched off after work. Energy-saving light bulbs are used in all our companies. When purchasing new electrical appliances, we pay attention to the energy efficiency classes and favour the better class. Wherever possible and sensible, we have installed motion detectors in the companies.


We take care to minimise water consumption during production and in our daily work. We are involved in the “Water for Water” and “Drink and Donate” projects to ensure the sustainable use of water resources. Our dishwashers are state-of-the-art and are characterised by optimal water management. We obtain our mineral water from Passugger in the canton of Graubünden.


Our machines are regularly professionally inspected and serviced. This ensures that the machines have a long service life and the smooth running of the processes is guaranteed. Minor repairs are carried out on site in our repair workshop. For new purchases, we pay attention to Swiss production.


Our cleaning agents are constantly being replaced with newer and more sustainable products. Our cleaning agent supplier is certified for sustainability and is committed to the careful use of resources worldwide. Our employees are trained in the professional use of cleaning agents. This ensures correct handling and protection of materials and the environment. The GAMMA Group has engaged an external hygiene consultant to test hygiene samples.


Our suppliers are long-standing partners who share our philosophy on sustainability and also represent and live the same values in our corporate culture. We rely on regional partnerships. This guarantees us short delivery routes and seasonal products that are grown in the region. Our partners know their products inside out and make us aware of more sustainable alternatives.


Precise planning is required to ensure that we use the required resources responsibly. We support our customers from the initial enquiry about an event right through to the follow-up work. Planning that conserves resources also includes early scheduling of employees. This enables them to achieve a good work-life balance. An internal and external feedback culture is a matter of course for us.
