Isifinyezo sokuqonda

I-Hempcrete, inhlanganisela ye-hemp kanye ne-lime, ivela njengenye indlela esimeme emkhakheni wezokwakha nowokwakha, ehlinzeka ngezakhiwo ezilungele imvelo, i-insulating, kanye nezindawo ezimelana nesikhunta. Isetshenziswa kakhulu yinkampani yaseDutch i-Overtreders, i-hempcrete izuza amandla ngenxa yomthelela wayo ophansi wemvelo kanye nokubola kwemvelo. Nakuba imvelo yayo enezimbotshana ibeka imikhawulo ethile, inikeza ukumelana nomlilo kanye nendawo enempilo yasendlini. Njengoba i-hempcrete izuza ukunakwa okwengeziwe, icatshangelwa ukubuyisela kabusha izakhiwo kanye nengqalasizinda yokubamba ikhabhoni. Ngezindawo zayo ezishisayo, amandla okudala amathuba emisebenzi, kanye nokusebenza emazweni asathuthuka, i-hempcrete isilungele ukuba yitshe lesisekelo emgudwini womhlaba wonke oya ekwakhiweni kwe-zero-carbon.

Umongo we-Hempcrete

I-Hemp njengamanje isetshenziswa ezimbonini ezahlukahlukene, kubandakanya ukukhiqizwa kwezingubo kanye ne-biofuel. Amandla ayo njengempahla yokwakha ehambisana nemvelo nayo ithola ukuqashelwa ngenxa yekhono layo lokuthatha ikhabhoni. Ikakhulukazi, inhlanganisela ye-hemp kanye ne-lime, ebizwa nge-hempcrete, isetshenziswa kakhulu kumaphrojekthi wokwakha i-zero-carbon ngoba ivikela kakhulu futhi imelana nesikhunta.

I-Hempcrete ihlanganisa ukuxubha i-hemp shive (izingcezu zokhuni ezincane ezivela esihlangeni sesitshalo) nodaka noma usimende we-lime. Nakuba i-hempcrete ingeyona eyesakhiwo futhi ingasindi, ingahlanganiswa nezinhlelo zokwakha ezivamile. Lokhu okubalulekile kungafakwa endaweni noma kwenziwe izinto zokwakha njengamabhulokhi noma amashidi, njengokukhonkolo okuvamile.

Isibonelo sezinkampani zokwakha ezisebenzisa i-hempcrete i-Overtreders, ezinze eNetherlands. Le nkampani yakha inkundla yomphakathi kanye nengadi isebenzisa amaphesenti angu-100 ezinto eziphilayo. Izindonga zazenziwe nge-hempcrete edaywe ebomvana etholakala ku-fiber hemp etshalwe endaweni. Inkundla kulindeleke ukuthi ithuthelwe emadolobheni ase-Almere nase-Amsterdam, lapho izosetshenziswa khona iminyaka eyi-15. Uma izakhi zokwakha ezimodulayo sezifinyelele ekupheleni kwesikhathi sazo sokuphila, zonke izingxenye ziyakwazi ukubola.

Ngenkathi i-hempcrete inezinzuzo eziningi njengempahla yokwakha, nayo inezingqinamba. Isibonelo, ukwakheka kwayo okunezimbotshana kunciphisa amandla ayo okusebenza futhi kwandisa amandla ayo okugcina amanzi. Yize lokhu kukhathazeka kunganikezi i-hempcrete ukuthi ingasetshenziswa, kubeka imikhawulo ebalulekile ekusetshenzisweni kwayo.

Umthelela ophazamisayo

I-Hempcrete iyasimama kuwo wonke umjikelezo wayo wokuphila ngoba isebenzisa udoti wemvelo. Ngisho nalapho sitshalwa, sidinga amanzi amancane, umanyolo nezibulala-zinambuzane kunezinye izitshalo. Ukwengeza, i-hemp ikhula ngokushesha futhi kalula cishe kunoma iyiphi ingxenye yomhlaba futhi ithela isivuno kabili ngonyaka. 

Ngenkathi ikhula, ikhipha amakhabhoni, ivimbele ukuguguleka kwenhlabathi, icindezele ukukhula kokhula, futhi ikhiphe ubuthi emhlabathini. Ngemva kokuvuna, isitshalo esisele siyabola, sengeze imisoco emhlabathini, okwenza kube yindlela ekhangayo yokushintshanisa izitshalo phakathi kwabalimi. Njengoba izinzuzo ze-hempcrete zigqanyiswa kakhulu, amafemu amaningi okwakha cishe azozama le nto ukuze afeze imizamo yawo ye-zero-carbon.

Ezinye izici zenza i-hempcrete ibe nezinto ezihlukahlukene. I-lime enamathela ku-hempcrete ayikwazi ukumelana nomlilo ngokwanele ukuvumela abagibeli ukuba baphume ngokuphepha. Iphinde inciphise ukubhebhetheka komlilo futhi inciphise nengozi yokuhogela intuthu ngoba iyasha endaweni ngaphandle kokukhipha intuthu. 

Ngaphezu kwalokho, ngokungafani nezinye izinto zokwakha, i-hempcrete ayibangeli izinkinga zokuphefumula noma zesikhumba futhi i-vapor-permeable, iqinisekisa indawo enempilo yasendlini. Ukwakheka kwayo okungasindi kanye namaphakethe omoya phakathi kwezinhlayiya zayo kuyenza ikwazi ukumelana nokuzamazama komhlaba futhi ibe isivikelo esinamandla sokushisa. Lezi zici zingase zikhuthaze ohulumeni ukuthi basebenze nezinkampani eziluhlaza ukukhiqiza izakhiwo ze-hempcrete prototype, ezifana ne-India-based GoHemp.

Izicelo ze-hempcrete

Ezinye izinhlelo zokusebenza ze-hempcrete zingabandakanya: 

• I-Hempcrete isetshenziselwa ukubuyisela kabusha izakhiwo ezikhona, ukunciphisa i-carbon footprint yemboni yezokwakha kanye nokwenza ngcono ukusebenza kahle kwamandla.
• Amafemu abamba i-Carbon asebenzisa i-hempcrete njengengqalasizinda yokuthathwa kwekhabhoni.
• Ukukhiqizwa, ukucubungula, nokufakwa kwe-hempcrete kudala amathuba emisebenzi ezimbonini zezolimo, ezokukhiqiza nezokwakha.
• Ukutshala i-Hemp kunikeza abalimi indlela entsha yokuthola imali. 
• Izakhiwo ze-Hempcrete zokushisa ezishisayo ezinciphisa ukusetshenziswa kwamandla ezakhiweni, okuholela ezindleko eziphansi zokushisisa nokupholisa.
• I-Hempcrete isetshenziselwa ukuhlinzeka ngezinketho ezingabizi, ezihambisana nemvelo zezindlu emazweni asathuthuka.
• Ukuthuthukiswa kwamasu amasha okucubungula nemishini okuholela entuthukweni kwezinye izimboni, njengezindwangu.

Imibuzo okufanele icatshangelwe

• Ohulumeni nabenzi bezinqubomgomo bangazithuthukisa kanjani izinto zokwakha ezisimeme njenge-hempcrete?
• Ingabe zikhona ezinye izinto zokwakha ezisimeme ocabanga ukuthi kufanele zibhekwe kabanzi?
