Plastic is in factnow central to the current industrial system, there are a lot of plastic typesand suitable for many uses, but just thinking to replace it seems entirelyimplausible. The produce of polyethylene, one of the cheapest plastics, forexample allows to create insulation for electrical cables, films foragriculture, bags and plastic bags, containers of various types, piping, innerlayer of aseptic liquid and food containers and many others. Moreover, contraryto what one may think, the use of plastics in some areas can achieve goodresults in terms of the environment. In construction, insulation using plasticfor every kilo of plastic has an annual saving of 75 kilos of fuel for heating.In transport, however, the plastic improves the aerodynamics of a cardecreasing the Cd (drag coefficients), it reduces the weight, thus resulting inlower fuel consumption (on average today 4% less than a full metal car) and thereduction of pollutant emissions. The car is the sector where there is thehighest level of use of recycled material. Another very important area is that of packaging, a recent study conducted in Germany have shown that without plastic packaging the weight of the product plus the onepackaging will increase by 291%, the energy used to produce the same 108% andvolume of waste by 158%. In the food, the use of plastic packaging can contain up to 2% the volume of goods that would otherwise reach up to 50%. In terms of mechanical recycling, the plastics used in this area is usually clean and uniform, and through a closed loop processing allow to obtain a high quality material which has a large market. Plastic is therefore now regarded as a must for the new ecology, particularly when recycled. The road to eco-friendly materials is now required and it is also known as a leading route of development for this market. Plastics are also extremely flexible and are perfect to indulge the creativity, as happened in the '70s with the development of design. The combination plastic-well being is now being establishing, especially in the cushioning material. Another very important field is the economic one. In furniture market, dominated by an handicrafts industry, plastic allows for a real industrial production. And the big numbers involve the killing of prices, without detracting from the quality.The plastic material is considered a pure, practical, flexible and technologicallyadvanced. A lot of companies have built all-plastic-objects with no attempt to mimic natural materials, claiming one's "plastic" nature linked to young people values of lightness, play, color and freshness.
