Eastern Environment Solutions believes that its technologies and landfill site design represent an improvement over traditional landfill methods. The vast majority of MSW generated in the PRC is ultimately sent to simple dump sites on the suburban outskirts of cities. These dump sites without any sanitation measures pose significant environmental hazards, particularly associated with leachate to underground water. Until 2004, very few landfill sites in the PRC were equipped with leachate collection and treatment systems, which are required in developed countries.

The design of the Landfill incorporates features to protect groundwater and surface water, prevent soil erosion, protect against fire and provide easy access to control landfill gases and leachate. It is designed to be compatible with the surroundings both during its active life and after it is closed.

The Landfill is designed to meet international standards and comply with all relevant local PRC regulations, including the Sanitary Landfill Technical Standards of Municipal Solid Waste issued by the PRC’s National Ministry of Construction. Eastern Environment Solutions has installed a synthetic 2mm high-density polyethylene membrane system at the bottom of the Landfill to prevent leachate from polluting underground water. It has also installed a gas treatment and collection pipe system at the bottom of the Landfill.

The Harbin Environment Sanitation Bureau is responsible for collecting and transporting MSW to the Landfill. At the entrance of the Landfill, inspectors inspect the waste for its compatibility with the Landfill. Once the waste passes inspection, it will be weighed using a computer-based weighbridge and then unloaded into the Landfill.

With the use of a bulldozer, the waste is pushed up to a height of 50-60 cm. In order to protect the HDPE membrane from tearing, the initial layer of waste will only be compacted when it reaches 3-meters thick. It will then be compacted into a 50-60 cm layer, with a waste density of more than 0.8 ton/m3. When the waste accumulates to a height of 2.5 meters, it will be covered with clay to prevent mosquitoes and flies from proliferating, and to prevent odor and light-weight waste from accidentally flying out of the Landfill. The Landfill is also sprayed periodically and sanitized to protect the surrounding environment and control mosquitoes.
