Ubuchwepheshe Besikebhe Esinobungani Nemvelo
Ukushintsha kwesimo sezulu, ukukhuphuka kwentengo kaphethiloli, kanye nesidingo somphakathi sezokuthutha okuhlanzekile kuqhuba ushintsho embonini yezolwandle. Emazweni amaningi asezindaweni eziqhelile njenge-Indonesia, izikebhe zidlala indima ebalulekile njengokuxhumana phakathi kweziqhingi, ukwesekwa kwezokuthutha, kanye nokuphila kwezokuvakasha. Kodwa-ke, izikebhe ezivamile ngokuvamile zisathembele kumafutha angaphansi komhlaba kanye nezinjini zedizili, ezikhiqiza ukukhishwa kwe-carbon dioxide (CO₂), i-nitrogen oxides (NOx), i-sulfur oxides (SOx), kanye nezinto ezincane. Ngakho-ke, ubuchwepheshe bezikebhe obunobungani nemvelo buyisisombululo esihlakaniphile sokunciphisa umthelela wekhabhoni ngaphandle kokulahla ukuphepha nokuthembeka kwensizakalo.
Kungani Kudingeka AmaFeri Ashintshe?
Umkhakha wezokuthutha unegalelo elikhulu ekukhishweni kwamagesi okushisa umhlaba kanye nokungcoliswa komoya ezindaweni ezisogwini nasemachwebeni. Ama-Ferry anezici zokusebenza ezihlukile: imizila engaguquki, amabanga aphakathi kuya kwamafushane, kanye nezinhlelo zokuhamba ngomkhumbi ezivamile. Lezi zici zilungele ukusetshenziswa kwezinto ezintsha ezifana nokufakwa kukagesi, amandla ahlanganisiwe, kanye nokwenza ngcono imiklamo yemikhumbi kanye nezinhlelo zamandla. Okwamanje, ohulumeni nezinhlangano zamazwe ngamazwe balawula ngokuqinile ukukhishwa kwamagesi. Izinhloso zokunciphisa ukukhishwa kwamagesi zikhuthaza abaqhubi ukuthi basebenzise ubuchwepheshe obusebenza kahle, ngenkathi benciphisa izindleko zokusebenza zesikhathi eside.
Ama-Ferry kagesi ebhethri: Akukho ukukhishwa kwegesi endaweni yokusebenza
Enye yezinto ezintsha ezithandwa kakhulu yisikebhe sikagesi esisebenza ngebhethri. Lolu hlelo luthatha indawo noma lunciphisa ukusetshenziswa kwezinjini zikadizili ngezinjini zikagesi ezisebenza ngamabhethri amakhulu. Inzuzo eyinhloko yezikebhe zikagesi ukunciphisa ukukhishwa okuqondile (ukukhishwa kwepayipi langemuva) kuye cishe ku-zero ngesikhathi sokusebenza. Ngaphezu kwalokho, izinjini zikagesi zivame ukuba nokuthula, kunciphisa ukungcola komsindo kubagibeli kanye nemiphakathi yasogwini.
