Disposal and Landfilling in industrialized and in economically developing Countries |
Since wastes were produced the routes for its disposal have been landfilling, recycling and combustion. From ancient times to the present, waste has been burned, reused or dumped with a qualitative level of processing which depends on the economical, cultural, social and political developments of organized people in their own particular situations (geography, climate, resources, etc.). The role of sanitary landfilling is changing in the light of the incoming waste disposal concept, but it must be considered carefully according to the present and the desired future situation. Each country has to develop its own disposal strategy, where landfilling invariably plays the most important role. Many industrialized countries are approaching the problem of waste disposal with a new strategy. The main aim of this strategy is to ensure the minimal environmental impact, saving raw materials by promoting resource recovery and reducing the amount of refuse to be disposed of. For developing countries, it is a big step to move from existing open dumps and uncontrolled disposal sites to sanitary landfills (Hogland W. et al., 2005). The locations of most landfills and dumps in Asia are based on convenience rather than hydrogeological considerations. The replacement of dump sites by landfills with higher sanitary standards will therefore only happen in the medium to long term. |
