Plastic nu rugineste, deci grebla ar putea sa tina vreo 400 de ani, cat tine PET-ul. ''Plastic bottles are commonly made from polyethylene terephthalate (Pet), which take 400 years to naturally decompose, yet is highly recyclable.''

Sau cumperi 5 din astea. https://www.emag.ro/...2/pd/DHFD2MBBM/ Edited by 77777-7, 09 November 2018 - 02:34. |
