supply as possible from CO2-neutral, renewable and regional energy sources. ZEGG generates all of its heating needs on-site. The lignite-fired power plant on the site was modernised in 2010. It runs on woodchips that are sourced from forests in the surrounding region. Around 85% of the electricity supply comes from photovoltaic plants and gas-powered combined heat and power plants (cogeneration plants). Additional electricity is purchased from Green Planet Energy that ensures the supply comes from renewable sources. A constructed wetland sewage treatment system was built in 1992, which purifies all the wastewater from the site in a specially planted marshy area, which also provides a new habitat for animals. The drinking water comes directly from groundwater through three wells. Permaculture is a guiding principle for ZEGG when it comes to developing and using its site. Mulch and green fertilisers ensure the sandy soil benefits from long-term improvements in fertility. As the soil became healthier, higher-order creatures followed, such as birds, hedgehogs, martens, toads and squirrels. The site has an edible landscape with indigenous fruit and leaves, as well as apricots, peaches, grapes, kiwi fruit, mulberries and figs growing in sheltered areas. Since 2013 ZEGG is experimenting with the use of Biochar and Terra Preta in building soil and fertility. For this purpose Urine is collected in waterless Urinals. The ZEGG garden (1 ha) follows organic gardening guidelines. Vegetables, salads and flowers are all thriving there, including pumpkins, carrots, leeks and kale. There are various sorts of fruit as well. Food provided for residents and guests at ZEGG is vegetarian and partly vegan. In the summer, the food comes from daily harvests in the garden, prepared in the large kitchens and served fresh to the guests. Additional food required is purchased from organic wholesalers, regional producers and/or fair trade sources. In 2004 ZEGG was awarded the second prize in the Agenda 21 competition in the local government district where it is located, Potsdam-Mittelmark, because of its woodchip-fired heating system and constructed wetland sewage treatment. In 2011, the community once again won the second prize in the district’s Agenda 21 competition, this time for its new, innovative energy concept. Site History The site on which ZEGG Community lives today had historical links to both German dictatorships. Its first settlement can be traced back to 1919, when it was used agriculturally with a market garden and small farm animals. Ownership of the site
