Recycling of plastics from stockpiles performed by means of low-pressure injection

Gintowt J.

Archives of Foundry Engineering

2010

Vol. 10, iss. 3 spec.

259--262

A viability analysis of manufacturing goods out of plastics, from stockpiles and municipal residues, has been carried out. The analysis pertains goods in the form of inserts manufactured in light molds of big-sizes, by means of low-pressure injection. The cost analysis of the investment and manufacturing suggests that those goods are not price-competitive, as compared to other ones used in similar situations. Exploitation analysis proves that the goods, used outdoors are easily damaged on the surface by UV exposure, temperature differences of 24-hour cycle, as well as by water and plants. Re-recycling, and especially, the grinding of the product poses another challenge in the future. An analysis of the environmental impact of energy acquisition during the manufacturing of those goods was also carried out. The analysis also pertains the method of identifying the type of raw-material, in the process of segregation that stems from the necessity of a complex content training of staff running waste segregation posts.
