Vuba aha, iterambere nubushakashatsi bwamacupa menshi ya PET hamwe nudupaki twa byeri nkintego nyamukuru yabaye ahantu hashyushye mu nganda, kandi iterambere ryinshi ryaratewe nyuma yigihe kinini cyubushakashatsi bunini. Inzoga zumva cyane urumuri na ogisijeni, kandi ubuzima bwo kubaho busanzwe bugera ku minsi 120. Umwuka wa ogisijeni w'icupa rya byeri urasabwa kutarenza 1 × 10-6g mu minsi 120, kandi gutakaza CO2 ntibirenza 5%.

Iki gisabwa ni inshuro 2 ~ 5 zumutungo wa barrière icupa ryiza rya PET; hiyongereyeho, inzoga zimwe zikoresha uburyo bwa pasteurisation kuri byeri, bisaba ko ubushyuhe bwo hejuru bugera kuri 298 ℃, mugihe imbaraga, kurwanya ubushyuhe, inzitizi ya gaze y icupa ryiza rya PET Imitungo ntabwo ijyanye nibisabwa n'amacupa ya byeri, kubwibyo, abantu ni kwiruka mubushakashatsi no guteza imbere ibikoresho bishya nibikorwa bishya kuri bariyeri zitandukanye no kuzamura.
