Umkhiqizo wezemithi

Imboni yezemithi ithola, ikhula, ikhiqize, futhi imakethi izidakamizwa noma izidakamizwa zemithi ukuze isetshenziswe njengoba imishanguzo yokuphakelwa (noma ukuzinikelwa) ezigulini , ngenhloso yokulaphula , noma ikwazi ukunciphisa izimpawu . Izinkampani ezenza imithi zingase zibhekane nemithi ejwayelekile noma yomkhiqizo namadivayisi wezokwelapha. Bangaphansi kwemithetho nemigomo ehlukahlukene elawula ukubheja , ukuhlola, ukuphepha, ukusebenza kahle kanye nokumaketha kwezidakamizwa . Imakethe yomkhiqizo womhlaba wonke kulindeleke ukuthi ikhule isuka ku- $ 1228.45 billion ngo-2020 kuya ku- $ 1250.24 billion ngo-2021 ngesilinganiso esingu-202%.

Ukutholwa kwezidakamizwa kuyinqubo lapho izidakamizwa ezingaba khona zitholakala noma zenziwa khona. Esikhathini esedlule, izidakamizwa eziningi zitholakele ngokuhlukanisa isithako esisebenzayo kusuka kumakhambi endabuko iBenzocaine Phenacetin noma ngokutholwa okuyi- serendipitous . I- biotechnology yanamuhla ihlala igxile ekuqondeni izindlela ze- metabolic ezihlobene ne-PVC resin isimo sezifo noma i-pathogen , kanye nokukhohlisa lezi zindlela zisebenzisa i-biology ye-molecular noma i - biochemistry . Isidakamizwa esikhulu esisezingeni eliphakeme se-Ethylene-vinyl acetate senziwe ngokwesiko senziwe ngamanyuvesi kanye nezikhungo zocwaningo.
