Mu gihe c'itumba, gushyuha bimaze kuba ikibazo.
Kubera iyo mpamvu, abantu benshi batangiye guhindukirira gaze gasanzwe no gushyushya amashanyarazi.Usibye ubu buryo busanzwe bwo gushyushya, hari ubundi buryo bwo gushyushya bugaragara bucece mu cyaro, ni ukuvuga gushyushya biyomasi.

Kubireba isura, iri ziko ntaho ritandukaniye nitanura risanzwe ryaka amakara.Ni umuyoboro uhujwe na chimney, kandi isafuriya irashobora gushyirwa ku ziko kugirango iteke amazi.Nubwo ikomeje kureba hasi, iri ziko ritukura rifite umwuga kandi ururimi-mumatama-biomass yo gushyushya.
Kuki yitwa iri zina?Ibi kandi bifitanye isano ahanini na lisansi yaka.Amavuta yatwitswe n'amashyiga ya biomass yitwa amavuta ya biomass.Kubivuga neza, ni imyanda isanzwe yubuhinzi n’amashyamba nkibyatsi, ibiti, bagasse, n umuceri wumuceri.Gutwika mu buryo butaziguye iyi myanda y’ubuhinzi n’amashyamba bihumanya ibidukikije kandi birabujijwe.Nyamara, nyuma yimashini ya biomass pellet ikoreshwa mugutunganya, yahindutse ingufu nke za karubone kandi zangiza ibidukikije, kandi ihinduka ubutunzi abahinzi barwanira.
Imyanda iva mu buhinzi n’amashyamba itunganywa na pelleti ya biomass ntikiri irimo izuba ritanga ubushyuhe, bityo rero nta myanda ihumanya iyo yatwitse.Byongeye kandi, lisansi ntabwo irimo amazi kandi yumye cyane, bityo ubushyuhe nabwo ni bunini cyane.Ntabwo aribyo gusa, ivu nyuma yo gutwika amavuta ya biomass nayo ni make cyane, kandi ivu nyuma yo gutwikwa iracyari ifumbire mvaruganda yo mu rwego rwo hejuru, ishobora gutunganywa.Ni ukubera neza kubera ibyo biranga ibicanwa bya biomass byabaye umwe mu bahagarariye ibicanwa bisukuye.
