Pomaliza, RPET imapereka yankho lokhazikika la zinyalala za pulasitiki zomwe zimagwiritsidwa ntchito kamodzi ndipo zimatha kuchepetsa kwambiri kuwonongeka kwa mapulasitiki pa chilengedwe.Kupanga ndi kutengera njira zina zokometsera zachilengedwe monga rPET popanga njira zopangira ziyenera kulimbikitsidwa ndi onse omwe akuchita nawo gawo.Ndikofunikira kudziwa kuti ngakhale RPET imabweretsa zabwino zambiri, ntchito yochulukirapo ikuyenera kuchitidwa powonetsetsa kuti pakhale njira zogulitsira komanso kulimbikitsa mitengo yobwezeretsanso kuti ikwaniritse zofunikira.
