Spam refers to the level 3 (or 4) Rs of reduce, reuse, recycle (and best) way to classify them according to desirability. RS is designed to be hierarchical, according to importance. However, the leadership of Europe to step 5: reduce, reuse, recycle, recovery and reuse.
Waste level has taken many forms over the last decade, but the basic concept has been based on waste minimization strategies more. The waste management goal is to reduce the maximum benefit from the product and provide a small amount of waste.
Some experts waste management recently taken R over "Re-thinking", because he said that the current system may be flawed primary system quite efficient waste management require new ways of looking at garbage. Source reduction involves efforts to reduce hazardous waste and other materials and transform industrial production. Source reduction techniques include changes in the technology industry, raw material inputs, and product development. Sometimes the term "pollution prevention" may refer to source reduction.
Another way to reduce the source is to increase incentives for recycling. Many in American society is implementing variable rate pricing for waste that has been effective in reducing the size of the waste.
Reducing the source is usually measured by the efficiency and reduce waste. Reduce use of toxic technique is controversial source reduction that targets and measures to reduce the use of the river of toxic materials. Reduce use of toxic stresses more prevention issues to reduce the source, but the emphasis on chemical inputs, has been opposed by the most powerful and chemical manufacturers. Toxic use reduction programs have been established by law in some states, for example, Massachusetts, New Jersey, and Oregon.
