Disused landfill site: In July 2015 a letter of intent with the Department of Ecology of the City of Chemnitz set the starting point for this final step of a sustainable land conversion. In the seventies this landfill has been used for collecting hazardous waste by the regional district of the former Republic of Eastern Germany. Since 1997 the meanwhile remediated and disused landfill site is adminstrated by the Waste Management Association of Chemnitz. The area of the site, which is used for the solar PV plant, has been recultivated by 2005. With consequent joint forces between the provincial headquartes of Saxony, the City of Chemnitz, Waste Management Association of Chemnitz and the team of ENERGISTO and its network partners this project could be successfully developed and realized. One speciality the partners involved had to face with was the sensitive handling of the surface of the recultivated landfill body.
