7Do not waste foodDesperdicio alimentario (Ley 1/2025, art. 5)

Spain's law 1/2025 requires food businesses to waste less food, in this order:

1. Prevent waste first: prepare the right amount. Turning unsold food into other food products (jam, juice) is part of this step too.
2. Donate good food to people, for example to a food bank.
3. Animal feed.
4. By-products used by another industry.
5. Compost, then energy.

The bin is the last option.

In a restaurant: if a customer wants to take leftovers home, give a free container that can be recycled or reused (buffets excepted).

At work: use older stock first, and follow labels and dates. Never donate food past its caducidad date or food left warm.
