“…Non-infectious waste can be safely disposed of by dumping in a sanitary landfill, which should be located far enough from communities. The sanitary disposal consists of compacting daily waste pick ups (Ikeguchi 1994). Ikeguchi considered the term sanitary disposal outdated and simplistic, it does not fulfil all requirements of modern disposal areas.…”

This study analysed the hospital waste management practices and their implications to public health in the city of Belo Horizonte, south eastern Brazil. Belo Horizonte is a regional capital city located 300 miles from the famous city of Rio de Janeiro, Brazil. It is only 100 years old and is the first city planned in Brazil. It was originally planned for 300,000 people but, today, it is home to more than 2 million people. This study assessed the operational procedures at five hospitals (170 to 450 beds) with different medical specialties in order to analyse their major waste problems. This study also gathered data on different types of treatment and disposal procedures used by waste generators, which enabled an estimate on the amount of on-site and off-site waste generated.

“…The characteristics of waste depositions at the landfill sites in Japan had drastically changed, from unprocessed municipal solid waste (MSW) to incinerator residue and incombustible MSW. In 1988, the new landfill guidelines were promulgated providing the standard values for facility and equipment as well as the new design criteria of leachate treatment facilities (Ikeguchi 1994).…”

Mathematical Modelling to Trace the Leachate Plume of the Municipal Landfill in Groundwater Environment

At outside, the landfill A in Japan contamination has been found. It has been believed that the leachate must leak out from the municipal landfill site. Therefore, simulation of the movement of leachate was carried out to understand the behavior of the plume at the landfill site. The plume movement was simulated by the three-dimensional solute transport coupled with groundwater flow under different assumptions such as faults, leachate collection pipe, sheet wall. Only advection and dispersion are included in the present paper. The finite difference method was used as the numerical method to solve the partial differential equations of groundwater flow and solute transport. The method of characteristics was applied to solve the advection term of mass transport equation. A valuable attempt of the present paper is to simulate the leakage of leachate. The paper demonstrated that the effect of the faults at the landfill site is the most important factor which controls the movement of the leachate to the outside. There is a possibility that the leachate plume may leak under the sheet wall to outside.

“…In semi-aerobic landfills, in which leachate collection pipes are connected to gas venting pipes, and the ambient air flows into landfill layer naturally through the leachate collection pipe, and subsequently improves the waste stabilization process by aerobic activity. Although the concept of semi-aerobic landfills can be easily understood qualitatively, engineering information such as diameter and distance of the leachate collection pipes and gas venting pipes in practice has not been obtained [4][5]. It is important to verify the advantages of semi-aerobic landfills through a comparative study using actual sites data and numerical simulation to forecast the long time behavior of semi-aerobic landfill stabilization [7][8].…”

Semi-aerobic method is a standard type of landfill currently used in Japan. Semi-aerobic landfill system enables to enhance the stabilization of landfilled solid waste utilizing the self-purification capacity inherent in nature. Although semi-aerobic method has been developed for about 20 years, the mechanism has not widely understood in many countries. The objective of this study is to make clear the influence of the laying condition (pipe diameter, pipe placement distance) of leachate collection pipe on the stabilization of landfill through numerical simulation, by use of landfill model constructed in this study with consideration of the interactions of microbial activity and the transport process such as gas transport, heat transport and material transfer between gas and liquid phases.
