Ma cobs amapangidwa ngati maziko othandizira mbewu za chimanga panthawi yomwe chimanga chikukula. Amapangidwa ndi cellulose, hemicellulose, ndi lignin, pamodzi ndi mapuloteni ena, mchere, ndi mafuta ochepa. Zinthu zimenezi zimapangitsa kuti cobs zikhale ndi mphamvu zapadera zakuthupi ndi zamakemikolo, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito m'njira zosiyanasiyana.

M'madera ambiri akumidzi, chimanga cha chimanga chakhala chikugwiritsidwa ntchito ngati gwero la mafuta. Kutha kwawo kuyaka nthawi zonse ndikupereka kutentha kwawapangitsa kukhala chisankho chabwino chotenthetsera nyumba m'madera omwe magwero ena amagetsi ndi osowa kapena okwera mtengo. Koma tsopano, ndi kupita patsogolo kwaukadaulo, tikuyang'ana njira zogwira mtima kwambiri zosinthira chimanga kukhala mphamvu, monga kudzera mu biomass pelletization kuti chitenthetse bwino komanso chosavuta.

Mu gawo la mafakitale, chimanga chikupanga chizindikiro. Chimagwiritsidwa ntchito popanga furfural, chinthu chofunikira kwambiri chopangira mankhwala. Furfural imatha kusinthidwanso kukhala zinthu zosiyanasiyana monga mapulasitiki, ma resin, ndi zosungunulira. Kuphatikiza apo, chifukwa cha kuchuluka kwa ma corncobs omwe amalowa m'madzi amawapangitsa kukhala abwino kwambiri ogwiritsidwa ntchito ngati zosakaniza. Chingagwiritsidwe ntchito kuchotsa zitsulo zolemera m'madzi otayidwa a mafakitale, zomwe zimathandiza pa ntchito yoteteza chilengedwe.
