Municipal Solid Waste Management Using Bioreactor Landfill in the Treatment of Organic Waste from Jatibarang Landfill, Semarang-Indonesia

Landfilling is one of the easiest methods to be applied in the management of municipal solid waste (MSW). In its development, bioreactor landfill methods that have various advantages over conventional landfill emerge. This experiment aims to study the use of bioreactor landfills for the management of organic waste in Jatibarang Landfill, Semarang-Indonesia. There are 4 bioreactor landfills operated: 2 anaerobic bioreactors with leachate recirculation and addition of water, and 2 aerobic bioreactors. Different results are shown from these two types of bioreactor, where aerobic bioreactors reach peak temperatures (55oC each) faster even though anaerobic bioreactors reach higher temperatures (60oC and 61oC respectively). Anaerobic bioreactors reach a higher final pH value than aerobes while the accumulation of nitrogen content from an aerobic bioreactor is 2 times higher than anaerobes.

Finding solutions to the problem of municipal solid waste management is impossible without involvement in the waste management system of the largest group of wastes – bioorganic waste, which form up to 60% of the municipal solid waste total mass. The aim of the article is to analyze the redistribution of biogenic elements subject to implementation of the Concept of solid municipal waste management by OSENU and subsequent utilization of bioorganic waste flow. Research methods include mass balance and equations of methane generation. The article presents the results of research on the biogenic elements migration in case of complex utilization of bioorganic component of municipal solid waste. The study shows that processing of easy-decomposed organic waste into a gaseous fermentation product and biomineral fertilizer allows full involvement of biogenic elements in natural cycles. The processed solid products present an additional source of organic matter and biogenic elements needed by soil. In the event of humus and nutrients shortage in soil the retrieved-from-waste fertilizer becomes an important secondary resource, containing up to 65% carbon and almost 100% nitrogen, phosphorus and potassium. The rest of carbon is released with biogas and is eventually involved in natural cycles. Burial of such waste results in localization of biogenic elements in a landfill's body and gradual release of carbon with the products of destruction (27% over 50 years). All this data indicate the need for efficient use of such waste resource potential which is possible in case of easy-decomposed organic waste separation at the beginning of the municipal solid waste life cycle. Combustion releases only carbon in the form of carbon dioxide, the rest remains in ash. However, complex utilization of easy-decomposed organic waste ensures complete return of biogenic elements to the environment. Reuse of secondary raw materials in the form of paper and textile waste minimizes involvement in economic turnover of carbon from natural sources.

Constant Deterioration

In the conditions of constant deterioration of the environment, municipal solid waste management (MSW) in Ukraine remains one of the most pressing challenges in environmental safety because of its significant accumulation in landfills and the lack of effective mechanisms for its disposal. Approximately 40- 50% of municipal solid waste is organic, so the removal of this part of waste from landfills through composting and conversion of waste into secondary material resources will significantly reduce the environmental load on existing and potentially planned landfills. Therefore, the choice of promising technologies for the disposal of organic waste is one of the major tasks to ensure environmental safety. One of the effective strategies for dealing with excessive amounts of organic waste and one of the best and most affordable technologies for the waste recycling system is composting.

Waste management, being one of the most important aspects of urban development, is gaining importance among developing nation like Nepal where rapid population growth, unmanaged urbanization, lack of public awareness and poor management by municipalities have intensified environmental problems in towns in Nepal. In Nepal only six municipalities i.e. Kathmandu, Lalitpur, Pokhara, Dhankuta, Tansen and Ghorahi practice sanitary landfill for waste management and other municipality practices open dumping which has become major cause of environmental and human health hazards (ADB, 2013).Jeetpur Simara Sub-Metropolitan City (JSSMC) is a recently formed sub-metropolitan city. This city has not performed any study on solid waste management till date and lacks data on quantity and composition of municipal solid waste generation that facilitates effective planning of municipal solid waste management. The household survey revealed an average per capita household waste generation rate of 120 g/capita/day. The total Municipal Solid Waste (MSW) generation is estimated about 15 tons/day and 5475 tons/year. The analysis of household waste composition indicated that the highest waste category was organic waste with 80% followed by plastics with 10%, paper and paper products with 6% and inert with 4%. The composition analysis of institutional wastes revealed 41% paper and paper products, 33% plastics, 13% organic wastes and 13% inert. The study found that commercial waste comprised 59% paper and paper products, 21% plastics, 17% organic and 3% inert. In aggregate, MSW is composed of 56% organic waste, 21% paper and paper products, 19% plastics, and 3% inert.

The U.S

In recent years, due to the advance in knowledge of landfill behaviour and decompositionprocesses of municipal solid waste (MSW), there has been a strong thrust to upgrade existinglandfill technology from a storage/containment concept to a process-based approach, in otherwords, as a bioreactor landfill. Operating landfills as bioreactors and hence enhancing thestabilization of wastes is one such option that has been elaborately investigated and hadalready been in practice in the U.S. and European countries, As compared to many developedcountries, the concept of leachate recirculation is still relatively new to Asia, Nevertheless,there are laboratory scale and pilot scale researches including few full-scale implementationof this technology in Asia, Research and development activities relating to aspects of landfillbioreactors are keeping the interest of scientists and engineers alive and enriching theliteratures. Findings of bioreactor landfill research have resulted in generation of enormousdata and their publication in variety of journals and books, Collating data from such diversesources would help understand the bioreactor landfill concept, benefits to be derived, designand operational issues, possible solutions to many of these issues, ongoing researches, etc,This paper is an attempt to present an overview in this direction in Asian perspective.
