Initiative Green Deal Lausitz – Federal republic

Every year, about 100 hectares of (CEA) greenhouses for fresh fruit and vegetables are built in Germany alone. The current degree of fragmentation of these agricultural sites prevents many opportunities. The strategic clustering of businesses in a specific region would bring significant benefits to the businesses hosted there, including cost efficiencies in energy, purchasing of inputs, training and workforce development.

People from a wide variety of professional backgrounds, whose careers are being impacted by market changes and the decline of coal mining can be upskilled into stable and attractive occupations. The growth of a fossil-free horticulture sector will also stimulate new and diverse businesses across the value chain of food and energy in the region.

Regional supply chains increase the degree of self-sufficiency in food supply, offering economic growth along with improved security, transparency and resiliency.

In the energy region Lausitz this initiative will demonstrate a repeatable systematic approach to aid in the transformation to a CO₂-neutral economy through the direct coupling of renewable energy and sustainable food production.

Converting underutilized brownfields for new power generation and greenhouse agriculture can bring economic revitalization to communities that have been negatively impacted by the decline of the coal industry. Upcycling real estate and upskilling workforce simultaneously can greatly accelerate the economic transformation of these regions.

By co-locating environmentally friendly fruit and vegetable production in greenhouses alongside industry 4.0 technologies, circular materials and energy cycles, land that was formerly used for open-cast mining can be made usable again within a short timeframe. This economic transformation will develop new opportunities for industry leaders and for local family businesses as the regional workforce is upskilled into future-proof careers.

Future-proof development that combines the latest proven technologies in energy, horticulture, and the digital economy will require the cooperation of domestic technology leaders along with foreign horticultural expertise. Aligning both German and Dutch entrepreneurship, supported by leading scientific research, will ensure a successful and scalable solution. This initiative will convene an international network of research institutes, service providers, local craftsmen and associated institutions across the value chain in order to build regional capacity and open new import/export opportunities in other European countries and beyond.

Approximately 10 million people live and work within a radius of 200 km around the Lusatian lignite mining, in the Euroregion of Germany, Poland and the Czech Republic. This region has significant unmet demands high-quality fresh fruits and vegetables, with a current self-sufficiency rate for vegetables is approximately only 38 percent.

Generating renewable energy from diverse sources requires additional measures to help manage consumption and keep the energy grid stable. Greenhouse operations, with their unique energy usage patterns, can provide an excellent buffer for renewable energy sources. Furthermore, greenhouse energy plans can be designed to repurpose waste heat from power plants and to adjust their energy usage during times of high power demand, improving grid stability and energy efficiency for all customers. This ability to improve the efficiency of renewable energy sources increases significantly with the clustering of larger greenhouses.

Today, modern greenhouse systems are able to use resources extremely efficiently. The rainwater used for irrigation is reused and thus protects soil and groundwater. Heat storage systems or the process heat of other companies provide a favorable climate in the greenhouses and biowaste is treated and returned to the plant cultivation. Ecological, economic and social sustainability are part of everyday life.

Under the premise that Germany strives for a CO₂-neutral economy within a few years, the key to success lies in the direct coupling of regenerative energy production and usage. The integration of CEA and greenhouse horticulture alongside renewable energy production in an innovative “microgrid” configuration will serve as an exemplary and future-oriented case study in sustainable development.

Greenhouse (CEA) sites are ideally suited to be located in areas where the environmental impacts of the coal industry have made the land unsuitable for other purposes. This development will help to preserve unspoiled habitats, creating large areas for renaturation and biodiversity while reducing pressure on arable agricultural land. Already existing horticultural clusters, such as Rain am Lech, Knoblauchsland, Papenburg, are currently facing barriers to expansion and are limited by challenging permitting requirements.

The combination of a renewable energy generation and sustainable crop production creates a climate-neutral model region.
