Ka hangaia ngā puku kānga hei tautoko hanganga mō ngā kākano kānga i te wā e tipu ana te tipu kānga. He mea hanga ēnei mai i te cellulose, te hemicellulose, me te lignin, me ētahi pūmua, ngā kohuke, me te iti o te ngako. Mā ēnei wāhanga ka hoatu ki ngā puku kānga ngā āhuatanga ā-tinana me te matū ahurei, e pai ai mō ngā momo mahi maha.

I roto i te nuinga o ngā rohe tuawhenua, kua whakamahia ngā kānga hei pūtake wahie. Nā te kaha ki te tahu tonu me te whakarato wera, kua waiho hei whiringa whai hua mō te whakamahana i ngā kāinga i ngā rohe he iti, he utu nui rānei ngā pūtake pūngao kē atu. Engari i nāianei, me ngā whanaketanga hangarau, kei te rapu mātou i ngā huarahi whai hua ake hei huri i ngā kānga hei pūngao, pērā i te whakapūmua i te koiora hei whakamahana ma, hei whakamahana watea ake hoki.

I roto i te rāngai ahumahi, kei te waiho te kānga hei tohu mō te tangata. Ka whakamahia ēnei hei hanga i te furfural, he matū takawaenga nui. Ka taea te tukatuka anō i te furfural hei hanga i ngā momo hua pēnei i te kirihou, te kapia, me ngā whakarewa. Hei tāpiri, nā te kaha o te porowhita o ngā kānga, he pai rawa atu ēnei hei whakamahi hei mimiti. Ka taea te whakamahi hei tango i ngā konganuku taumaha mai i ngā wai para o ngā ahumahi, hei tautoko i ngā mahi tiaki taiao.
