Ubwatsi bw'ingano ni ubwoko bushya bw'icyatsi kibisi kandi cyangiza ibidukikije bikozwe mu guhuza fibre y'ibimera karemano nk'ibyatsi, ibishishwa by'umuceri, selile na polymer resin binyuze mu nzira idasanzwe. Ifite imiterere isa na thermoplastique isanzwe kandi irashobora gutunganyirizwa mubicuruzwa hifashishijwe ibikoresho byo gutera inshinge.Ibikoresho bikozwe mu byatsi by’ingano birashobora kubora byoroshye na mikorobe mvaruganda mu ifumbire y’ibimera, ntibitera umwanda wa kabiri, kandi bifite ubuzima bwiza kandi byangiza ibidukikije.

Kuramo ibikoresho byo kumezani icyatsi kandi cyangiza ibidukikije. Nibimera byibimera byangiza ibidukikije. Ibikoresho fatizo byingenzi ni fibre yibimera nkibimera nkibyatsi by ingano, ibyatsi byumuceri, umuceri wumuceri, ibyatsi byibigori, ibyatsi byurubingo, bagasse, nibindi. Ibikoresho fatizo byibicuruzwa byose nibimera bisanzwe. Mubisanzwe byahinduwe mubushyuhe bwinshi mugihe cyo gukora. Nta myanda ihari, nta gaze yangiza n’imyanda isigara mu gihe cyo gukora. Nyuma yo kuyikoresha, bashyingurwa mu butaka kandi bisanzwe byangirika mu ifumbire mvaruganda mu mezi 3.

1.Ibyatsi by'inganoibikoresho bya fibre bigabanya cyane igiciro cyibicuruzwa. Igiciro cyibikoresho bya pulasitiki bikoreshwa birarenze cyane ugereranije n’ibikoresho fatizo bibora.

2. Ibyatsi byumuceri, ibyatsi by ingano, ibyatsi byibigori, ibyatsi bya pamba, nibindi ntibishoboka kandi birashobora gukoreshwa bidasubirwaho. Ntabwo ari ukuzigama gusa ibikomoka kuri peteroli bidasubirwaho, ahubwo ni no kuzigama ibiti n'ibiribwa. Muri icyo gihe, zirashobora kugabanya neza umwanda ukabije w’ikirere uterwa no gutwika ibihingwa byatereranye mu murima w’ubuhinzi n’umwanda ukabije w’umweru ndetse n’ibyangizwa n’imyanda ya pulasitike ku bidukikije n’ibidukikije.
