As the policies banning the ocean dumping of waste gradually become effective, ocean dumping of industrial sewage sludge is prohibited from 2014 with temporary allowance until 2015 in the case of being unable to treat it on the ground. While various recycling methods including composting and vermicomposting of sewage sludge are being explored, the cost of recycling treatment is increasing in trend. The amount of sewage sludge in Gyeonggi Province is the highest in Korea with 3,838.3 tons per day and the average treatment cost per ton at public sewage treatment facilities increased compared to 2015 to 107,148 Korean Won per ton, highlighting the need for consideration of efficient treatment methods through process innovation and treatment method in sewage treatment.
In the case of sewage sludge resulting from industrial facilities, recycling and utilization are difficult due to harmfulness or securing location for final treatment facility for industrial waste is hampered by opposition from local communities. Therefore, it is necessary to consider alternative treatment methods such as incinerating, reutilizing after consolidation, or turning into fuel.
Based on survey results about waste treatment facility, 90% of the respondents answered to have no improved operation to promote recycling of sewage sludge, suggesting little efforts to reutilize after the ban on ocean dumping and highlighting the need for further efforts on reutilization of sewage sludge.
The survey indicated that the respondents desire “installation and management of treatment facility at the regional- and community-levels” for treating sewage sludge and showed that they prefer “connected treatment with private recycling operators,” “connected treatment at public environmental facility,” and “connected treatment with cogeneration power plants.” For efficient treatment methods in the future, “turning into fuel after drying” and “composting” received a high number of responses.
Accordingly, it is necessary to prepare appropriate recycling plans for different types of sewage sludge depending on the characteristics of harmful substances in emission, and to revitalize related industries by securing recycling treatment facilities. In addition, as reduction in costs of collection and transportation, fuel utilization in adjacent areas and reductions in greenhouse gas are possible when turning sewage sludge into fuel at combined power plant facilities adjacent to industrial complexes, it is necessary to consider plants for turning sewage sludge into fuel at combined power plant facilities.
As the combined utilization of regular and industrial wastes at public waste treatment facilities has been proposed based on the principles of “Optimization Plan for Waste Treatment Facility” by Ministry of Environment, it is possible to consider plans for utilizing slack capacity at public waste incineration and landfill facilities.
As a result of survey on the treatment cost of sewage sludge, it was shown that current treatment costs of sewage sludge are over 120,000~140,000 Korean Won per ton in 42.4% of the responses and that appropriate treatment costs for incineration and landfill are below 200,000 Korean Won per ton in many cases. Therefore, it is possible to consider calculation based on “Treatment Costs of Types of Wastes for Calculation of Fulfillment Guarantee Payments for Waste Treatment.”
