Abstract: PET is a popular package for food and non food products. Manufacturers use PET plastic to package products because of its strength, thermo-stability and transparency. Costumer schoose PET because it is inexpensive, lightweight, resealable, shatter-resistent and recyclable. Recyclated polyethylene terephthalate (RPET) can be used to make many new products, including fiber for polyester carpet, athletic shoes, luggage, fiberfill for sleeping bags and winter coats, industrial strapping, sheet and film and new PET containers for both food and non-food products.
Key words: PET recycling, economy, environment, impact

THE СIRCUIT OF SUBSTANCES AND THE ENERGY SOURCES IN THE ANTHROPISED ECOSYSTEMS
СIRCUITUL DE SUBSTANŢE ŞI SURSELE ENERGETICE ÎN ECOSISTEMELE ANTROPIZATE

Gheorghe NICULIŢĂ
Universitatea de Stat Tiraspol, Chişinău, Republica Moldova
Abstract: The action of the human activity on the environment is emphasized, as well as the result – the individualization of antrhopised ecosystems. It is shown that, unluckly, the economic prosperity of a region often causes the degradation of the nature. The “ecological strain” is discussed, which is directly depending on the production processes.
Key words: energy circuit, environment, anthropic impact
