Plastic wastes reduction

The former may be more supportable than the latter. If a proper quantity of an appropriate plastic is dissolved in an asphalt, properties of the asphalt will be modified to become more suitable for road paving. Maybe, there are some sorts of appropriate plastics like that in the wastes. However, the proportion of the appropriate plastics to the all waste plastics will is not high. The optimum volume of the plastics dissolved in the asphalt to modify properties of the asphalt is not high too. Therefore, the former utilization does not spend much waste plastics and it is not a effective way for the plastics waste reduction. 

The latter may spend comparatively much waste plastics become, because they are utilized as aggregate. If the waste plastics used as aggregate have a good influence upon the properties of asphalt mixture, the latter is an effective way for plastics waste reduction. 

With plastics taking up 20% of volume of municipal solid waste and costs of landfilling and incineration rising rapidly, waste reduction efforts focus on development of plastics recycling technology.

Concentrated products lead to a reduction of plastic waste and distribution costs. They enable space savings on the shelves at the point of sale and at home. Their success, however, varies strongly from country to country introduced in Germany in 1980 [14], they represented 95% of the German rinse cycle fabric softener market in 1994 and only 10% of the Spanish and Italian ones [21], In France and the U.K. they are at parity with regular products [5], Likewise, they appeared on the Japanese market in 1988 and represented 50% of sales six years after [5], On the contrary, in emerging countries, regular products still remain the most popular, as consumers feel they get more for their money. 

The increase in the use of plastic materials in all sectors of industry and in everyday life, as well as the reduction in the lifetime of most plastic products, have led to a continuous increase in the generation of plastic wastes. Figure 1.7 illustrates the distribution of solid wastes by sector in Western Europe for 1996. The total volume of waste was 2.6 x 109 tonnes, although the total post-user plastics waste accounted for only 1.7 x 107 tonnes, i.e., only 0.6 wt% of the solid waste was plastic materials. 

A process to convert plastics waste to naphtha has also been tested in Japan. A volume reduction machine is used to dissolve plastics wastes into waste oil, reducing the volume of waste. The solution is then processed to naphtha in a 5000 tonnes/year plant.

Municipal Solid Waste and Hazardous Waste Waste incineration is the most effective method of waste reduction. All other recycling routes involve more waste in the total recycling chain (Fig. 13.29). The special case of mechanical recycling substituting wood or concrete, apparently saving more waste than they replace, is due to the assumptions made. In the case of concrete substitution, the portion in excess of 1 kg/kg of recycled plastic results from the low density of mixed plastics compared with the far heavier concrete product. The wooden product generates more MSW on final disposal than the mixed plastic solely because of the assumed life expectancy ratio of 4.
