Njengesixhobo esisisiseko kuxilongo lwezonyango, ukucinezelwa kolwimi kusetyenziswa kakhulu kuvavanyo lomlomo kunye nomqala, okukhokelela kwimfuno ezinzileyo neyomeleleyo yentengiso. Kwiminyaka yakutshanje, ngokuhambela phambili kwemigangatho yezonyango yehlabathi kunye nokwanda kolwazi lwezempilo yoluntu, imarike yokudambisa ulwimi ibonise ukukhula okuzinzileyo.
Ngokusekwe kwizinto eziphathekayo, ii-depressants zolwimi zihlelwe ngokukodwa kwiindidi ezintathu: umthi, iplastiki kunye nentsimbi. Izicinezeli zolwimi lweplanga lwesintu, ngenxa yexabiso eliphantsi kunye nokulula kokusetyenziswa, zisabambe isabelo esikhulu semarike kumazwe asakhasayo. Nangona kunjalo, i-wooden depressors yolwimi iyakwazi ukuphuka kwaye ibeka imingeni ekulawuleni ucoceko, ibangela ukuba amanye amaziko ezonyango atshintshe kwiplastiki ehlala ixesha elide okanye izinto zetsimbi. Izixhobo zokucinezela ulwimi lweplastiki (ezifana ne-polypropylene) zithandwa kakhulu kumazwe aphuhlileyo anje ngeYurophu kunye ne-United States ngenxa yobunzima bazo, indalo elahlayo kunye nokuthobela imigangatho engqongqo yonyango yokuvala inzala. Izidambisa ulwimi lwesinyithi (ezifana nentsimbi engatyiwayo) zisetyenziswa ikakhulu-kwiimarike eziphezulu okanye zisetyenziswa ngokuphindaphindiweyo. Ngaphandle kweendleko eziphezulu, zibonelela ngokuqina kwaye zilungele ixesha elide{6}, ukusetyenziswa rhoqo.
Imarike yehlabathi yokucinezela ulwimi ibonisa umahluko wengingqi. Iimarike ezivuthiweyo zaseMntla Melika naseYurophu, kunye neemfuno ezingqongqo zokhuseleko kunye nokuthotyelwa kwezixhobo zonyango, ziye zaqhuba ukuthandwa kwezinto ezilahlwayo zokucinezela ulwimi lweplastiki. Kwiimarike ezikhulayo ezifana ne-Asia Pacific, uMbindi Mpuma, kunye ne-Afrika, imfuno yokuxinzelela ulwimi iyaqhubeka nokunyuka, iqhutywa kukukhula kwabemi kunye nokuphuculwa kweziseko zonyango, kodwa iimveliso zokhuni zisabala inxalenye ebalulekileyo.
Uphuhliso lwexesha elizayo lwemakethi yokucinezela ulwimi luya kuphenjelelwa yimigaqo-nkqubo yezonyango, imimiselo yokusingqongileyo, kunye nokwenziwa ngokutsha kwetekhnoloji. Iinkxalabo zokusingqongileyo ezijikeleze iiplastiki ezilahlwayo zinokuqhuba ukusetyenziswa kwezinto ezinokubola, ngelixa ukunyuka kwezixhobo zonyango ezikrelekrele kunokuba nefuthe kwimakethi yemveli yokudambisa ulwimi. Lilonke, njengesiseko sonyango esisetyenziswayo, imfuno yentengiso ye-depressants yolwimi kulindeleke ukuba ihlale izinzile, kodwa ukuphuculwa kwezinto eziphathekayo kunye nokutshintsha okuthandwayo kwabathengi bengingqi kuya kuba ziindlela eziphambili.
