\nMajivu ni nyenzo nyeupe au nyekundu inayobaki baada ya mkaa wote kuchomwa, ambayo ndiyo tunayoita majivu. Ukubwa wake unaathiri moja kwa moja matumizi na thamani ya kiuchumi ya mkaa. Kwa mfano, majani, ganda la mpunga na vitu kama hivyo vina kiasi kikubwa cha majivu, na si rahisi kutenganishwa wakati wa kuchoma, na kusababisha joto la chini wakati wa kuchoma, ambalo halifai kwa maisha ya watu na mkaa wa viwandani. Bila shaka, watu wanataka majivu ya mkaa kuwa madogo kadri iwezekanavyo ili kupanua matumizi yake.
\nYaliyomo ya majivu ya makaa ya mawe yatatofautiana kulingana na mchakato na joto la mchakato wa kaboni. Hata hivyo, kwa upande wa miti au mabaki yake, tofauti katika majivu baada ya uundaji wa kaboni si kubwa. Kwa ujumla, chini ya hali zilizotajwa hapo juu, makaa ya mawe yanayowaka katika msitu wa majani mapana yana kiwango kikubwa zaidi kuliko msitu wa miongoni. Na malighafi yenye uwiano mkubwa wa gome inachomwa. Majivu ya makaa ya mawe pia ni makubwa zaidi. Majivu ya makaa ya mawe ya kawaida yako kati ya 1 na 4%.
