摘要
One possibility of preserving raw materials is to recycle manufacturing residues of products while using said products and also of waste products and waste materials. As regards these three modes of recycling the recycling while using the product is considered the most effective in terms of preserving resources. By employing relatively little efforts said mode extends the life of the product by simultaneously decreasing the consumption of raw materials to a substantial degree. Very often recycling as such is considered a miracle drug capable of closing the material circle and providing us with endless raw material resources. This is not true, since also recycling is ecologically limited. First of all, waste material and waste products have to be collected and separated by types. Apart from such obstacles there is also the ecological break-even-point as regards recycling. Like all other processes the performing of recycling processes requires use of primary resources. By developing products according to recycling needs together with suitable recycling logistics the ecological break-even-point can be effectively transferred to more recycling. A product design created in accordance with recycling needs should also include a design endowed with the possibility of separating materials without destroying such materials, and it should also allow for identifying the materials, and for selecting materials in accordance with recycling needs. By employing such measures the exhaustion of resources can be delayed in terms of time.
