This is a specialised collection facility located inside Mercabarna where the wholesale companies of the Central Markets and CAZ as well as retailers can separately dispose of the waste from their commercial activity (organic matter, cardboard, plastic, wood, expanded polystyrene, etc.). A series of specialist companies are then responsible for recycling the collected waste.

All pavilions of the central markets have containers/compactors where wholesale operators can separately deposit organic matter, plastic containers, cardboard, wood, etc. Companies from these centres that generate high amounts of waste (more than half a pallet) must take it directly to the Green Point and not leave it in the containers.

A team of 25 people work day and night to keep Mercabarna clean. To perform this task, they have a vehicle fleet designed specifically to clean the estate's facilities, characterised for being highly efficient and less polluting.

55% of water used to clean the estate comes from the subsoil.

Mercabarna, together with Barcelona City Council, promotes the implementation of the electric vehicle when distributing goods around the city. 

Additionally, as part of this policy, the P2 high-rise car park has three charging stations for electric vehicles. 

• Agreement to build a centralised cooling network that will supply the cooling facilities of Mercabarna's companies and reduce CO₂ emissions.
• Low-consumption LED lighting system in the Wholesale Markets and streets.
• Photovoltaic covering on the Mercabarna-flor and Biomarket roofs.
• Actions aimed at reducing the consumption of drinking water in the centralised management facilities, such as, for example, audits of the industrial processes, new irrigation systems, water extraction from the aquifer, reviewing facilities to ensure there are no losses, among others.
