How to Reduce Food Waste at Events: Practical Tips for Sustainable Catering

Aperitivos para cócteles de bodas

The fight against food waste is no longer just an ethical choice: starting in 2025, it is also a legal obligation. The new Food Waste Prevention Law requires all sector players — including event catering — to take real measures to prevent and reduce food loss.

At Gourmet Catering & Eventos, we have been committed to this for some time, but we know that change is only possible if our clients also join us. That’s why we want to share how you can help us make your event a more responsible experience, aligned with sustainability and current regulations.

Why is it important to avoid food waste at events?

Every year, tons of food are discarded after celebrations, weddings, conferences, or corporate events. This has not only an environmental impact but also economic and social consequences. Thanks to the 2025 Food Waste Prevention Law, a fairer and more efficient model is promoted — one that makes better use of resources and encourages surplus food donations.

How can our clients help prevent food waste?

1. Accurately adjust the number of guests

Good planning of attendee numbers is the first step to reduce food excess.

Recommendations:

  • Confirm the number of guests as early as possible.
  • If the event is open, establish realistic attendance margins with our team.
  • Inform us about the attendee profile (itinerary, ages, dietary restrictions).

2. Design sustainable and tailored menus

Fewer options don’t mean less quality. Designing a balanced, optimized menu with seasonal products significantly reduces the risk of waste.

Tips:

  • Let our culinary team advise you in choosing appropriate dishes.
  • Opt for zero-waste or circular cooking menus.
  • Consider smaller or single-product stations to avoid leftovers.

3. Communicate the sustainability approach to guests

Awareness is key. If attendees understand the event’s sustainability purpose, they are more likely to cooperate.

Suggestions:

  • Include messages in invitations or event signage.
  • Promote responsible consumption at buffets and stations.
  • Highlight the importance of respecting special diets.

4. Donation and reuse of leftovers

Whenever food is in good condition and complies with regulations, we can allocate it to social organizations through established agreements.

How we integrate this:

  • We manage the logistics for food reuse.
  • We offer the option to communicate this charitable action during the event.
  • We provide follow-up to share the positive impact achieved.

A sustainable event is a team effort

Reducing food waste at events is possible when we work together. At Gourmet Catering & Eventos, we apply internal protocols, production controls, use local products, and collaborate with food banks. But the commitment multiplies when you, as a client, participate as well.
