Gahunda ya 80 ya karubone ibyuma ni ubwoko bwumuyoboro urangwa nurukuta rwarwo ugereranije nizindi gahunda, nkurutonde rwa 40. "Gahunda" yumuyoboro bivuga uburebure bwurukuta rwayo, bigira ingaruka kumyuka yumuvuduko n'imbaraga zubaka.
Ibintu by'ingenzi biranga ingengabihe 80 Umuyoboro wa Carbone
1. Ubukuta bwurukuta: Ubunini burenze Gahunda ya 40, butanga imbaraga nigihe kirekire.
2. Igipimo cyumuvuduko: Igipimo cyumuvuduko mwinshi kubera kwiyongera kwurukuta, bigatuma bikwiranye na progaramu yumuvuduko mwinshi.
3. Ibikoresho: Byakozwe mubyuma bya karubone, bitanga imbaraga nigihe kirekire, hamwe no kurwanya kwambara.
4. Gusaba:
Imiyoboro y'inganda: Ikoreshwa mu nganda nka peteroli na gaze, gutunganya imiti, no kubyaza ingufu amashanyarazi.
Amazi: Birakwiriye kumirongo itanga amazi menshi.
Ubwubatsi: Byakoreshejwe mubikorwa byubaka aho imbaraga nyinshi zisabwa.

Gahunda 80 Umuyoboro wa Carbone
Ibyiza:
Imbaraga Zirenze: Urukuta runini rutanga uburinganire bwubaka.
Kuramba: Gukomera kwicyuma cya karubone no kurwanya kwambara bituma iyi miyoboro iramba.
Guhinduranya: Birakwiriye muburyo butandukanye bwo gusaba n'inganda.
Ibibi:
Uburemere: Urukuta rurerure rutuma imiyoboro iremereye kandi birashoboka ko bigoye gukora no kuyishyiraho.
Igiciro: Mubisanzwe bihenze kuruta imiyoboro ifite inkuta zoroshye kubera gukoresha ibikoresho byiyongereye.
