The 21st century through the world development continues to progress rapidly. Industry is growing by leaps and bounds and cities are overflowing with people. At the same time mass production in mass consumption are generating volume of waste so huge sometimes authorities are unable to cope. Giving rise to mountains of waste. In many cases the inappropriate management of waste result in water contamination and other forms of pollution.
In the nineteen fifties and sixties when Japan went through a period of high economic growth it face similar waste related problems arising from rapid urbanization including increases in waste and worsening in the sanitation environment through ineffective waste management. In response the government revised and enacted various laws relating to management and disposal of waste and undertook measures such as the construction of disposal facilities (eddy current equipment) and the development of technology, well progress was made in the sanitary disposal of waste. The amount of waste generated continue to grow making it difficult to secure adequate disposal facilities and to handle disposal volumes.
In an effort to improve the situation since the nineteen nineties recycling laws have been employed. On 2000 the Basic Act for establishing a Sound Material Cycle Aociety was enacted. Establishing the foundations for policy that prioritizes the 3 R’s. Reduced, Reused and Recycle.
It's a pity to waste things and encompasses the practice and treasuring things as long as possible. This principle applies to the policy that prioritizes the 3 R's. Today as a part of the effort to prioritize the 3 R's in the whole world waste from household is sorted prior to collection in line with the slogan if its mixedd its waste if its sorted its a resource. As for difficult to recycle combustible waste my volumes have been reduced by about ninety percent through incineration on the thermal energy generated as a result of this process is utilized effectively in things like power generation and water heating. Ash and other materials left at the end of the incineration process are disposed in landfill.
Today waste management and recycling technologies and systems are among the most advanced in the world. Let's take a closer look at some of these technologies and systems. Waste incineration facility built and operated in one of world busiest shopping and entertainment area. Each day an average of three hundred twenty tons of waste is delivered to this waste incineration facility for burning. The reason a waste incineration facility exists in such a densely populated area is due to the application that advance incineration technologies and systems.
