Namuhla, ngaphandle kokuvela kwamandla avuselelekayo emhlabeni wonke, izinto zokubasa ezimbiwa phansi, kufaka phakathi uwoyela kusengenye yezinsiza ezibaluleke kakhulu emhlabeni. Izinto eziningi esizisebenzisayo osukwini lwethu usuku nosuku zivela kumafutha. Isibonelo, oplastiki, imithi eminingi, okunye okuncane, okokubasa, njll. Zivela emafutheni.
Njengoba sinikezwe le nsiza ebalulekile nokusetshenziswa kwayo okuhlukahlukene, kufanele sihlaziye ezinye izindlela zikawoyela njengoba, njengoba kwaziwa, ingumthombo ongavuseleleki futhi useduze nokukhathala. Enye yezindlela ezitholwe osomabhizinisi njengokufaka esikhundleni samafutha kungaba isitshalo sikaphayinaphu. Uphayinaphu ungawuthatha kanjani esikhundleni uwoyela?
U-Esteban Bermúdez ungumqambi osemusha waseCosta Rica futhi unguzakwethu owasungula i- EScotland. Le yinkampani ethuthukisa amaphrojekthi ahlukahlukene amasha lapho izoguqula khona izinsalela zensimu kaphayinaphu ibe yimikhiqizo kusuka kumthombo wamandla ovuselelekayo. Ngaphandle kokukhiqizwa kwamandla, kukhona nokunye ukusetshenziswa okuye kwafundwa futhi okungaba, ngokwesibonelo, ukwenziwa kwama-biofuels, umanyolo wezolimo noma amakhowe adliwayo.
Lo msunguli osemusha ubelokhu ehlaziya okwenziwa yi-Central America futhi ebona ukuthi ingumkhiqizi ophayinaphu omkhulu kunabo bonke emhlabeni, kanye nomlingani wakhe UBjøorn Utgärd, bakha i-Escoia.
Umqondo lapho iBermúdez iphefumulelwe ukhona kuwo umnotho oyindilinga. Inika ithuba lesibili izinsalela zamasimu aphayinaphu. Bakwazile ukuguqula umshini ukuze ukwazi ukwelapha i-biomass futhi ngale ndlela banganciphisa umswakama wezinhlanga. Ngale ndlela benza kube lula ukubhujiswa kwabo. Ukuze baqhamuke nalo mbono, baqala ngonyaka we-2014 ukucwaninga nokuhambela amasimu ophayinaphu. Amahektha ezitshalo angaphezu kwama-43.000 lukaphayinaphu odala udoti, kungaguqulwa kube amandla neminye imikhiqizo.
Njengoba amasimu kaphayinaphu kufanele avuselelwe njalo eminyakeni emibili ngenxa yezizathu zokukhiqiza, izinhlanga ezisele zifuthwe ngemithi yokubulala ukhula kanye nezibulala-zinambuzane, ngakho-ke kufanele zishiswe. Kodwa-ke, laba somabhizinisi bafuna ezinye izindlela zokunciphisa umthelela wezemvelo futhi khulisa inzuzo.
Okusha sekuvele kuyasebenza, ngakho-ke kuhlala kuphela ukuthi ngo-2017, bangenza indawo yokwelapha izinsalela zezitshalo zikaphayinaphu. Ngale ndlela, a umshini we-biorefinery nezinsizakusebenza zingakhiqizwa ngodoti.
