Sochi Waste Treatment Complex
OJSC Tunnel Brigade №44, a member of the Transstroy Holding, is the investor and contractor for the project to build a state-of-the-art solid household waste treatment complex in Sochi. The city’s planners say some 300,000 tonnes of waste will be generated per year by 2014.
The project involves building two technologically inter-related sites:
1) A modern complex to sort up to 200,000 tonnes of waste on the territory of a disused incinerator in the city’s Khosta district. The complex will have lines to treat recyclable materials; to produce commercial compost from organic waste by the aerobic method; and to recycle PET, polypropylene (PP) and polyethylene (PE) waste for industry.
2) A new landfill site for non-recyclable solid waste in the city’s Lazarevskoye district in the interfluve between the Buu and Khobza rivers, projected life of 15 years and area of 12 hectares. The site will host a waste-sorting complex, capacity 100,000 tonnes, with lines to process organic waste.
The two sites will enable up to 50% of recyclable waste such as paper, cardboard, ferrous and non ferrous metals, glass, textiles, PET, PP and PE to be put to further use.
Particular attention will be paid to the production of agricultural compost, sourced in approximately 80,000 tonnes of organic waste which the city generates by the year. Similar Strabag-Anlagen production lines have, for example, been installed at a waste treatment complex in Alicante, Spain. The technology not only resolves the carbon sequestration problem but also puts biomass back into the soil to restore the nutrient cycle.
The leftover waste, or tailings, will be briquetted and stored in the new landfill in such a way as to enable it to be salvaged and more useful material recovered from it at a later stage, as technology advances.
The landfill will have a degassing system to recycle the methane produced and thus substantially mitigate the site’s impact on the atmosphere. The landfill’s effluent will be treated locally before being removed for further treatment at the municipal waterworks.
System for collecting, removing, treating and recycling solid household waste in Sochi
OJSC Tunnel Brigade №44 initiated the reform and establishment of a modern system for collecting, removing, treating and recycling solid household waste in Sochi. The investment contract was signed with the City of Sochi in 2005.
International expertise was used to draft the strategic aspects of the system's development, and a general scheme for cleansing the city, locating installations and selecting methods for the treatment and recycling of solid waste.
The Sochi administration, municipal cleansing and refuse disposal department and Tunnel Brigade №44 have set up a dedicated waste management enterprise, OJSC Sochi Waste Treatment Complex, which will be responsible for the waste treatment system as a whole and individual sites, including for the 14th Winter Olympics in Sochi.
The Mayor of Sochi, in November 2006, approved a general scheme for cleansing the city, calling for a strategy for the period to 2020, which takes environmental, social and economic factors into account. The strategy incorporates the following:
1. Modernizing and optimizing the system, for collecting and removing solid household waste.
2. Organizing waste treatment complexes with the separation of useful waste.
3. Organizing commercial production from secondary material.
4. Organizing production of compost (organic fertilizer) from the organic content of solid waste.
5. Equipping a new state-of-the-art landfill site for non-recyclable solid waste.
6. Closing and re-cultivating existing sites for the storage of solid waste.
Main principles of the strategy: zero discharge and zero waste.
The Russian government, with a decree of June 11, 2008 (#443), amended an earlier decree (#991) of December 29, 2007 on the program of Olympic Venues Construction and Development of Sochi City as a Mountain Climatic Resort as one measure to amend the general scheme for cleansing the city and bringing this into line with the general plan for the city’s development in the period to 2032. The planners will adjust forecast volumes of solid household waste and logistics flows, but the main strategic decisions will remain in force and be taken further, as they comply with the zero-waste commitments set down in the Bid Book submitted to the International Olympic Committee.
