Ecological principles are put into action daily at piccoplant. For example, this includes the closed water cycle on the company grounds which ensures that all the plants are provided with water. An ecological purification plant is integrated into the facilities. The water flows through several pools and small artificial streams to enrich itself in oxygen. Iris plants swim in the pools and constantly clean the water using their brilliant symbiotic root system. The North German countryside is traditionally known for its hedgerow walls. The piccoplant grounds are also surrounded by them. Artificial banks of earth are planted with local nut and fruit shrubs and trees. These hedgerows not only provide protection from the wind and enclose the grounds but also provide a habitat for numerous animals, small vegetation and fungi. The hedgerows have also since begun to house a rich variety of bird species.
