Our greenhouses are equipped with modern energy screens and double glazing to efficiently save on heating costs. Additionally, we collect rainwater over the entire roof area of 9,000 square meters and use this water exclusively to irrigate all of our crops. The rainwater is collected in underground tanks with a total volume of 600,000 liters. Since 2007, we have been heating our entire operation with a fully automated 850 kW wood chip heating system and a 100,000-liter buffer storage tank. Environmentally friendly and CO2-neutral. Only to support on very cold winter days and nights is there still a conventional oil heating system available. Since 2014, the heating has been supported by a solar thermal system with an annual yield of approximately 20 megawatt hours. In 2020, we installed a photovoltaic system with a peak output of 30 kW and have since been producing more green electricity per year than our entire operation requires. Since 2021, we have been using exclusively pots for our self-produced plants that are not only 100% recyclable but are also made entirely from recycled pots. To achieve this, we collect all used pots that arise in our operation and have them picked up in bulk bags by our pot supplier Göttinger. There, the pots are cleaned and processed in a water-free recycling facility into new pots that come back to us.
