Wɔtaa de yɛ carbon dioxide (a wɔfrɛ no carbonation) wɔ anonne a ɛyɛ dɛ nkotoku mu. Nea wɔde di dwuma nso ne sini, ntama, nhama, tray, nneɛma a wɔde kyerɛ, ntade, ne waya a wɔde siw mframa ano.

B. CPET na ɔkyerɛwee
Wɔde PET resin a wɔayɛ no crystallized na ama ne hyew a ɛtumi gyina ano no yɛ kɛseɛ na ɛyɛ CPET (Crystallized Polyethylene Terephthalate) krataa. CPET yɛ nea ɛda adi sɛ ɔhyew a ɛkorɔn a ɛko tia, mpɛn pii no ntam -40 ~ 200 °C, yɛ ade pa a wɔde yɛ ovenable plastic aduan trays, awia aduan nnaka, nkuku. Mfaso a ɛwɔ CPET so: wotumi de di dwuma bio wɔ curbside na ebetumi akɔ recycle bin no mu pɛɛ bere a wɔahohoro awie no; Ɛnyɛ nea asiane biara nni ho sɛ wode bedi dwuma wɔ microwave ne frigye mu; Na wobetumi asan de saa nnuan nkuku yi nso adi dwuma bio.
