In 2007, local governments belonging to the Lusatian Association of Municipalities established a commercial law company called: "Zakład Zagospodarowania Odpadów Sp. z o. o. ", in order to implement the project entitled "Waste management within the Żary and Żagań poviats." In 2010, the company signed an agreement with the National Fund for Environmental Protection and Water Management for co-financing the project from the Cohesion Fund under the Infrastructure and Environment Operational Program. The scope of the project included: construction of the Waste Management Plant in Marszów, Żary commune, construction of the Waste Reloading Station in Lubsko, reclamation of waste landfills: in Chełmica (Tuplice commune), in Chrobrów (Żagań commune), Lubsko and Drzeńsk Mały (Gubin commune). Thanks to reclamation, we have restored 11 hectares of green area to nature. The owner and operator of the plant is Zakład Zagospodarowania Odpadów Sp. z o. o

The modern Waste Management Plant in Marszów started its operation on February 2, 2015. It is a municipal facility for 22 communes of the Lubuskie Voivodeship. The waste management system of ZZO Marszów reached over 200,000 inhabitants. The plant operates on the basis of the technology of mechanical and biological treatment of municipal waste (MBP). The total capacity of the plant is min. 72,000 Mg / year of municipal waste per year.

From the beginning of its operation, the Company has been looking for new solutions and methods of waste management in order to recover as many secondary raw materials as possible and to ensure that as little waste as possible goes to the landfill. Thanks to the activities of ZZO Marszów, secondary raw materials are recovered: paper, glass, plastics and metals, which are then recycled.
