The increasing solid waste management problems in developing countries necessitated landfill mining to determine the reuse potentials of landfilled solid waste materials. In this study, characterization of landfilled solid waste obtained from a closed landfill site in Malaysia was conducted to ascertain its reuse potentials for biodegradation in wastewater treatment. The results revealed adequate neutral pH, Moisture Content of 34 %, Organic Content of 10.4 % and Bacterial Population in terms of Total Coliform of 8.3 × 105 CFU/100 mL, which are ideal conditions for biodegradation while porosity n of 51%, allow free flow of water during treatment. The SEM showed irregular shapes and pore spaces and a BET surface area of 3.376 m 2 g-1 which enables adsorption of pollutants on its surface, air diffusion and re-aeration. Furthermore, the waste material was used as media for biodegradation in a lab-scale bioreactor at a hydraulic loading of 4 L m-3 d-1 and inflow rate of 0.1 L min-1. The results showed maximum removal rates of 95, 97, 86, 70, 70, and 98% for COD, BOD, TSS, TDS, NH3-N, and TP respectively. Utilization of this technology as bioreactor landfills will solve landfill congestion and also provide cheap wastewater treatment option.

Abstract Municipal solid waste management (MSWM) is one of the major environmental issues in Tunisian cities. Rapid growth in urbanization and population rates and the changes in people’s lifestyle have prompted a dramatic increase quantity and a significant shift in the composition of municipal solid waste. There is insufficient data concerning the quantities and the composition of waste streams along with the absence of a comprehensive complete overview and a wider perspective of MSWM potential that provides detailed information at region and city level. As a result, it is still impossible for the scientific community and the authorities to provide synergetic schemes to tie the problems of MSWM with how to integrate economically feasible and environmentally sustainable practices holistically. In the present study, an attempt has been made to provide a comprehensive overview of MSW, through a qualitative (compositional) and quantitative (parametric) characterization of the generated total waste generated in Tunisian cities. A 1-year research survey was conducted in seven regions in Tunisia (Great Tunis, Northeast, Northwest, Midwest, Mideast, Southwest, and Southeast) that cover the 24 provinces of the country. Collected samples revealed that the distribution of waste by region was defined by the region’s demographic, economic, and industrial status. Approaches of possibly more efficient procedures that can be undertaken to improve MSW collection are discussed. At a final stage and based on the potential of biogas calculated in the seven regions, we suggest that the scientific community and the authorities should introduce applicable schemes to valorize MSW through generating biogas as a renewable energy.

High Organic Content

The use of domestic garbage disposers may reduce the amounts and improve the solid waste composition, by lowering putrid matter and water content and by raising the caloric potential. However, additional loading on the sewerage systems might require increased investments and operation costs of the wastewater treatment facilities. This project analyses additional amounts of solids, biosolids and process requirements connected with wastewater treatment facilities resulting from the domestic use of garbage disposers, as well as the additional production of biogas. It was found that the use of the domestic garbage disposers in 60% of the households in a given urban area, is expected to reduce the weight, volume and water content of the solid waste by 7.0%, 3.3% and 4.4% for garbage characterized by low organic content, and by 18.7%, 11.0% and 13.3% for high organic content, respectively. The additional amounts of sludge are expected to be the lowest in case of biological treatment only, 24 to 38 g/capita/day, and the highest in case of primary chemical sedimentation followed by biotreatment, 67 to 100 g/capita/day. In these conditions the energy potential from biogas obtained in anaerobic digestion of sludge from wastewater collected from the same area, will increase by 50% to 70%, depending on the wastewater treatment sequence. The investment in wastewater treatment is estimated to increase by 23% to 27% and the annual costs for operation and maintenance are expected to increase by 26% to 30%.

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.

Wastewater Treatment Systems

India is home to almost one-third of the world's population that survive without adequate sanitation facilities. Bremen Overseas Research and Development Association (BORDA) in collaboration with the Consortium for DEWATS Dissemination (CDD) Society, has developed for the last 10 years, integrated solution packages for the provision of basic urban sanitation facilities. The customised packages include all or part of key sanitation elements like: toilets, decentralised wastewater treatment systems (DEWATS), health and hygiene education, solid waste management, drainage system, stakeholder participation measures. Over the last decade, with the support of its network partners CDD Society has been successful in delivering around 400 sanitation systems in South Asia. Due to the rapid growth of its population, India may require 1.3 million sanitation systems alone in the coming years. One of the key issues in meeting this huge target is the lack of trained professionals and implementing agencies. To upscale the efforts in delivering basic needs services in the sanitation sector, the Basic Needs Services (BNS) Network has started the establishment of a capacity building institution for decentralised sanitation solutions called Centre for Advanced Sanitation Solutions (CASS). CASS aims at providing the entire range of knowledge and skills required for the implementation of integrated sanitation solutions such as technical know-how for designing toilets, decentralised wastewater treatment systems (DEWATS), drainage systems, solid waste management and drinking water source protection; social support measures include health and hygiene education, community-based participatory planning tools as well as project management related aspects. For town and city managers, CASS will offer planning support for city and town-wide sanitation programmes. Furthermore, sanitation related R&D activities, knowledge management and exhibition is offered under CASS's ‘One-Stop-Shop’ concept; all components of sanitation are provided under one roof. This paper presents the basic components of the capacity building strategy developed by CDD/BORDA focusing on target groups, development of knowledge units (training module) and the didactical approach.
