Inkunkuma yokuThengiswa kweNkunkuma yeThuthi ngaphantsi kweekhonkrithi okanye i-Steel Structure
Inkunkuma yokhuni yinkalo yesibini enkulu enkulu yokwakhiwa nokubhujiswa (i-C & D) i-debris emva kwekhonkrithi . Igalelo lama-20 ukuya kuma-30 ekhulwini kwi-C & D ehambelana nesakhiwo. Ngokubanzi, ii-akhawunti zeenkuni malunga neepesenti ezili-10 zezinto eziphathekayo zifakwa kwiifowuni zokuhlawula iindleko ngonyaka. Le statistic yinkxalabo kubaphathi-nkqubo, abaqaphela ukuba izinga lokubuyisela i-C & D elithatyathwe ngomthi liphantsi kakhulu kunezinye izinto ze-C & D ezifana nekhonkrithi kunye nezakhiwo zensimbi.
Ngokomzekelo, izinga lokubuyiswa kwekhonkrithi malunga neepesenti ezingama-82, ngokwempahla yoKwakhiwa kweMpahla yokuThengiswa kweMpahla (i-CMRA), ngelixa i-recycling rate ye-steel structure isingama-98 ekhulwini, ngokutsho kwe-Steel Recycling Institute.
Ukukhutshwa kweNkuni yeNkuni evela kuMasipala kunye noC & D Umsebenzi
Ekubeni i-70.6 yezigidi zeetayibrari zedolophu zasezidolophini zaveliswa e-United States ngo-2010, kubandakanywa ipesenti ezingama-48 ukusuka kwintsimi engqongileyo kamasipala kunye nama-52 ekhulwini kwakha kunye nokubhubhisa (i-C & D). Kwiminyaka emininzi edlulileyo, uMbutho weZakhiwo zokuThengiswa koLwabiwo lweMpahla ukuqikelela ukuba ezinye iitoni ezingama-29 zeemfucuza zifumaneke ukuze zifumaneke emva kokuvumela amanqanaba amanje okuphucula, ukuvutha kunye nezinto ezingenakusetyenziswa. Ngelixa i-CMRA ingenayo inani elingaphambili elikhoyo, liyabonisa ukuba kukho ukwanda kwangoko kwenkqubo yokuphinda iphinde ibuyele kwishishini ukususela ngelo xesha.
Inkunkuma yenkunkuma yeC & D, ngokukodwa, isizukulwana sesiqingatha sonyaka siqikelelwa kwiitoni ezingama-36.4, kunye ne-29.7 yezigidi zeetoni ezithathwe kwimisebenzi yokubhubhisa kunye neetoni eziyi-6.7 ezilwakhiwo.
Ngokwezifundo zase-UK, malunga ne-10 ukuya kwi-15 ekhulwini zeenkuni ezisetyenziselwa ukwakhiwa olutsha ziphela ekuhlaziyweni kwakhona okanye kwimilambo yamanzi. Emva kwemizamo yokuvuselela yangoku okanye imithi engekho yokubuyiswa kwakhona ngenxa yokunyangwa kweekhemikhali okanye enye imicimbi, kusekho imithombo engapheliyo ye-17.3 yezigidi zeetayibrari zemithi yasemadolobheni ezifumanekayo ukwenzela ukuvuselelwa rhoqo ngonyaka.
Indlela iNkunkuma yeNkuni esuka kwiC & D ibuyiswe ngayo
Inkunkuma yokhuni esuka kwimisebenzi ye-C & D ihanjiswa ngokutsha kwimisebenzi yokubuyiswa kwezinto zokukhutshwa kweenkuni zokucubungula, nangona imarike encinci ikhona kwiiplanga ezithanjisiweyo, amabhodi okanye ezinye izinto.
Izixhobo zokuHlanywa kweziThuthi Izixhobo ezininzi ezinxulumene neC & D zifunyenwe kwiindawo zokucubungula zeC & D. Okokuqala izinto zingahle zihlelwe zixhobo ezinzima ezifana nabaqhubi be-front-end or excavators ngokuxhomekeka kwimiba yezinto eziphathekayo, ngaphambi kokutya kwindlela yokutya. Ngenxa yeenkunkuma ezinkulu zemithi, izixhobo zokunciphisa ubuninzi ezifana ne-compactor okanye i-shear hydraulic zingadingeka ukunciphisa ubuncinci bezinto ezibonakalayo ukwenzela ukuba inokutsalwa kwindlela yokutshisa imithi. Iinkqubo zogqithiso ziquka iinkalo ezivumela ukuhlengahlengiswa kwezixhobo zakwamanye amazwe, kubandakanywa isinyithi esinezitshixo, ngaphambi kokungena kwizixhobo zokugaya. Emva kokuhlola ukulingana okufunekayo kwimfuneko ethile yefayibrari, umveliso ukhona ukuthengiswa.
Ukusetyenziswa kwakhona kweenkuni Ukubuyiselwa kunye nokuphinda kusetyenziswe kwakhona kweemithi kukhula ngokukhawuleza ekuthandeni, nangona i-niche encinci ngokwemiqulu yonke. Imithi evuliwe iyanconywa ngabakhi bezindlu kunye nabanini. Ngokungafani nezinye izinto ezisetyenzisiweyo, i-woodwood ebuye ibuye idayise ngokuthengisa kwi-premium kwizinto eziphathekayo, ngenxa yezabasebenzi ababandakanyekayo kwi-deconstruction kunye nokuqhutyelwa phambili ukukhupha izipikili ezindala okanye ukuphinda umatshini.
Amakethi aMatye aKhuselweyo
Iimakethi zokhuni ezenziwe ngokutsha zibandakanya i-mulch-landscaping, i-bedding material, i-fuel boiler, kunye ne-fiber yeemveliso zebhodi ezidibeneyo, kuquka i-Presswood pallet kunye ne-pellets.
