Rosk´n Roll Ltd is a waste management company that has a landfill in western part of the Uusima region (city of Lohja) representing modern, environmental impact minimizing and energy self-sufficiency maximizing ideology. In 2007 Rosk´n Roll ordered Doranova’s landfill productivity system that supports the company’s environmentally friendly concept.
Rosk’n Roll’s landfill gas burning-torch was replaced with micro turbine that exploits the collected gas in electricity and heat production. The created electricity was utilized in landfill’s buildings and equipment. The heat created is now used to heat a building where the landfill’s other main component, reverse osmosis is located. Reverse osmosis is a method offered by Doranova to treat landfill’s leachated waters. The reverse osmosis system in Lohja handles 10m3 of leachate water in an hour and separates clean water from dirty concentrate. The productivity system was built in fast phase and we delivered the project only three months after starting the work.
