Frequently Asked Questions
What is Zero Food Waste verification for events?
It's an official certification that verifies your event responsibly manages food waste, from planning to closing. Based on the international standard The PLEDGE™ on Food Waste, the verification guarantees that every stage (purchasing, serving, donating, or recycling) is carried out with sustainability and traceability criteria.
Why should I certify my event?
A Zero Food Waste verified event demonstrates a genuine commitment to sustainability. Beyond its environmental impact, it generates a positive reputation, enhances the attendee experience, and can attract sponsors, brands, or institutions seeking to partner with responsible initiatives. Furthermore, it helps reduce costs by optimizing food purchasing and usage.
What types of events can obtain verification?
Any type of event can be catered: from festivals and food fairs to congresses, weddings, conferences, or corporate events. The process is tailored to the size, number of attendees, and suppliers involved, evaluating both the catering and the subsequent management of any surplus.
How does the verification process work?
It begins with a preliminary assessment to understand the event's current impact. Next, concrete measures are implemented to reduce, redistribute, and measure leftover food. Finally, an independent auditor reviews the results and awards Zero Food Waste certification, along with an impact report and best practices guide that you can share with your attendees and partners.
What do I need to get started and how much does it cost?
All you need is commitment and organization. We'll guide you every step of the way: from catering planning to final waste measurement. The cost depends on the size and duration of the event, but always includes consulting, promotional materials, and official verification. In less than 30 days, your event can become a benchmark for sustainability.
