WATER AND LEACHATE MANAGEMENT AT A SANITARY LANDFILL IN EXTREME TROPICAL CONDITIONS, KUCHING, SARAWAK, MALAYSIA
Kuching Integrated Waste Management Park (KIWMP) is located in the state of Sarawak, Malaysia. It has three main components; sanitary landfill, secure landfill and a hazardous waste incinerator. This site was identified after an intensive geographical and geological research was carried out. The total area covers 112 ha. Both sanitary and secure landfill were constructed section by section using TRISOPLAST as the base liner which is a highly impermeable and in many respects, a liner of superior to conventional liner systems. This seems fit to the requirement of this “fast track” project which was completed on 30th October 2004. In 2005 at the 19th Sardinia Symposium a presentation about the Park in general has already been given (Damiecki et al, 2005). This presentation will focus on the water and leachate management system.
In the extreme tropical area of Kuching with an annual rainfall between 6,500 and 7,200 mm a leachate treatment plant is operated which has to keep Standard B of the Malaysian Environmental Quality Act 1974. The plant consists of biological, chemical and physical
treatment steps. Since the plant´s capacity is limited to 350 m³/d the landfill operation – especially surface covering – has to be done on a high level. By using the statistical tool of the cumulated frequencies line it could be shown that the plant´s performance with regard to the COD effluent concentration could be improved distinctly within the last two years.

LEACHATE MANAGEMENT STRATEGIES AT LARGE TROPICAL LANDFILLS: A CASE STUDY
© IWWG International Waste Working Group (10/2007)
At tropical landfills, the demands on leachate management are often onerous and most acute in the initial stages of a landfill development. The daily and annual leachate generation rates can be very high, and leachate treatment can form a significant proportion of the landfill operating cost. Therefore, the development of an effective leachate management system is an essential part of the financial viability of a tropical landfill. Once the management system is developed, robust financial projections for leachate treatment throughout the life of a project can be derived. The Bukit Tagar landfill, near Kuala Lumpur, in Malaysia, illustrates the complexity of developing viable leachate management systems for tropical landfills, and highlights the importance of the relationships between the design, construction and operation.
THE EFFECTS OF LOCAL CULTURAL AND SOCIO-ECONOMIC FEATURES ON THE STRUCTURE OF SOLID WASTE MANAGEMENT IN DEVELOPING COUNTRIES: THE CASE OF THE PHILIPPINES AND VIETNAM
© IWWG International Waste Working Group (10/2007)
Solid waste management is a major responsibility of local governments. It is a difficult task because it depends upon organization and cooperation between households, communities, private enterprises, and municipal authorities. It is also dependent upon the selection and application of appropriate technical solutions for waste collection, transfer, recycling and disposal. Waste management has important consequences for public health and well-being, and the quality and sustainability of the urban environment. Unfortunately, waste management services in many developing countries are inadequate; a large part of the population does not have access to a waste collection service and only a small fraction of the generated waste is actually collected.
MUNICIPAL SOLID WASTE MANAGEMENT IN CHENNAI CITY, INDIA

Municipal Solid Waste includes commercial and residential wastes generated in municipal or notified areas, in either solid or semi-solid form excluding industrial hazardous wastes, but including treated bio-medical wastes (MoEF, 2000). The quality and quantity of MSW generated by a particular community will vary according to their socio-economic status, cultural habits, urban structure, population and commercial activities. Asian countries are facing MSWM problems due to the rapid growth in MSW generation rate. The total quantity of waste generated by 23 metro cities in India was 30,000 tpd in 1999, which has increased considerably to about 52,000 tpd (Inance et al, 2004).
SOLID WASTE MANAGEMENT IN SMALL MUNICIPALITIES: THE CASE HISTORY OF PIRAÍ (RJ), BRAZIL
© IWWG International Waste Working Group (10/2007)
Urban solid waste management in developing countries has been one of the major problems faced by public administration, and many municipalities have deficient domestic waste collection, poor street cleaning services and their waste disposal in open dumps. The management of urban solid waste is presently a serious problem in the majority of Brazilian municipalities. Although there has been some improvement in the past few years, more than 70% of the municipalities still dispose of their waste in open dumps, with notorious consequences to the environment and public health. In Rio de Janeiro State, only three municipalities have sanitary landfills licensed by the Environment State Agency.
THE CHARACTERISTIC OF LEACHATE AND CURRENT STATUS OF LEACHATE TREATMENT TECHNOLOGY IN VIETNAM

Leachate can be defined as a substance that permeates through solid waste layers in landfill which bring some soluble substances or suspended substances (Tchobanoglous etal., 1993). In most of landfill, leachate includes liquid going into landfill from out sources, such as surface water, rain fall, underground water and liquid generated from decomposition process of wastes.
