Rewe Opens Second Green‑Farming Wooden Supermarket
Rewe has opened its second Green‑Farming supermarket in Berlin, returning the timber‑built store format and rooftop farm five years after a Wiesbaden pilot. The store has about 2,150 sqm of sales area and a 2,700 sqm rooftop farm expected to produce roughly 900,000 salad heads per year (availability from summer). Rewe said it invested about €15 million in the location; construction used ~1,800 cubic meters of domestic wood and took 14 months. The site runs on 100% green electricity, has 200 solar modules, and reuses cooling waste heat; deliveries are made by e‑truck. The timber supermarket concept will be rolled out in Berlin, Bavaria and Lower Saxony, though not every site will include a farm.
A format and sustainability update from a major German retailer affecting store operations and in‑store merchandising; limited direct impact on the wider AdTech/MarTech industry.
