V. I-biodegradability enokuphinda isetyenziswe kwiikomityi zephepha le-ice cream
Iphepha leplanga lenkuni linokurisayikilishwa kwaye linokonakala. Oku kuphucula kakhulu ukusebenziseka kwakhona kunye nokonakala kwezinto eziphilayoiikomityi ze-ayisikrimu.
Emva kwexesha elide lophuhliso, indlela eqhelekileyo yokubola iikomityi zephepha le-ice cream ngolu hlobo lulandelayo. Kwiinyanga ezi-2, i-lignin, i-Hemicellulose kunye ne-cellulose yaqala ukuhla kwaye ngokuthe ngcembe yancinci. Ukususela kwiintsuku ezingama-45 ukuya kwezingama-90, indebe iphantse ibole ibe ngamasuntswana amancinci. Emva kweentsuku ezingama-90, zonke izinto zifakwa i-oxidized kwaye ziguqulwa zibe ngumhlaba kunye nezondlo zezityalo.
Okokuqala,izixhobo eziphambili zeekomityi zephepha le-ayisikrimu yipulp kunye nefilimu ye-PE. Zombini izixhobo zinokuphinda zisetyenziswe. I-Pulp inokuphinda isetyenziswe ephepheni. Ifilimu ye-PE inokucutshungulwa kwaye yenziwe kwezinye iimveliso zeplastiki. Ukurisayikilishwa kunye nokusetyenziswa kwakhona kwezi mathiriyeli kunokunciphisa ukusetyenziswa kobutyebi, ukusetyenziswa kwamandla, kunye nongcoliseko lokusingqongileyo.
Okwesibini,iikomityi zephepha le-ayisikrimu zine-biodegradability. I-Pulp ngokwayo yinto ephilayo echithwa lula yi-microorganisms. Kwaye iifilimu ze-PE ezonakaliswayo zinokonakaliswa zii-microorganisms. Oku kuthetha ukuba iikomityi ze-ayisikrimu ziyakwazi ukuhla ngokwemvelo zibe ngamanzi, i-carbon dioxide, kunye ne-organic matter emva kwexesha elithile. Ngoko ke, ayibangeli ukungcoliseka kwendalo.
Ukucocwa kwezinto eziphilayo okunokurisayikilishwa kubaluleke kakhulu kukhuseleko lokusingqongileyo. Ngeengxaki ezikhulayo zokusingqongileyo zehlabathi, uphuhliso oluzinzileyo luye lwaba sisihloko esixhalabisayo kuwo onke amacandelo oluntu.
Kwinkalo yokupakishwa kokutya, izinto ezinokuphinda zisetyenziswe kunye nezinto ezinokuboliswa yi-biodegradable yindlela yophuhliso lwexesha elizayo. Ke ngoko, ukukhuthaza ukupakishwa kokutya okunokurisayiklishwa kunye ne-biodegradable kubaluleke kakhulu kuphuhliso lweshishini kunye neshishini lokhuseleko lokusingqongileyo.
