REWE Green Farming Berlin: Agriculture on the roof and digitalization in the foundation<\/h2> <\/div>\n <\/div>\n <\/div>\n <\/a>\n <\/button>\n<\/div>\n <\/div>\n<\/div><\/div>\n\n\n\n

Shopping in the supermarket below, growing lettuce above: the REWE Green Farming store in Berlin-Lankwitz shows how the supermarket is evolving. Germany’s largest rooftop farm is being built above the wooden market hall. From the summer, lettuce will be growing here – just a few meters above the heads of customers. With the opening of the second REWE Green Farming store on 21 May, REWE is launching the scalable implementation of a new generation of supermarkets.<\/p>\n

With REWE Green Farming, we are further developing our green building strategy and combining circular building with urban food, explains Peter Maly, Management Board member of REWE Group. The core element of the new supermarket generation is wood. The renewable raw material offers clear advantages over conventional building materials: it stores carbon and, thanks to its modular construction, the wood can be dismantled and recycled for a second life. The cycle is also closed during operation: Waste heat from the market, a heat pump and rainwater from a cistern provide optimum growing conditions for the urban lettuce on the roof. According to Peter Maly, what seems special today will become standard tomorrow: “Our new generation of supermarkets is now going into series production, and thanks to the modular design, we can adapt the use of the roof optimally to the location. We are already planning further timber construction stores in Germany.<\/p>\n <\/div>\n\n <\/div>\n<\/div>\n\n

From pilot to scalable solution<\/h2>\n

The location in Berlin builds on the experience of recent years: REWE has realized more than 350 green buildings since 2009, with a further 130 in planning. the first green farming store followed in Wiesbaden in 2021. On this basis, the concept was further developed and optimized for broader implementation. With the location in Berlin, it is now being scaled up. <\/p>\n

A central element is the direct link between food production and retail. On the rooftop farm, lettuce is grown in an automated, hydroponic cultivation process with virtually no soil. ECF Farmsystems is behind this visionary cultivation concept: the Berlin-based company will operate the glass rooftop farm in the future. The team around founder Nicolas Leschke stands for innovative food production in urban areas. The first lettuce will be harvested from the supermarket roof from the summer. After harvesting, they will be processed in the market, packaged and sold on site or prepared for transportation. In the future, up to 900,000 lettuce mixes can be produced annually and supplied to around 500 markets in the capital region. Compared to imported goods from southern Europe, this will save around 500,000 transport kilometers per year.<\/p>\n <\/div>\n\n <\/div>\n<\/div><\/div>\n\n\n\n
