Jam'in tsarin amfani da ma'adinan lime (hadakar, yin yashi, yin tururi) an nuna shi a cikin hoto kamar yadda ke ƙasa.
Fa'ida
1. Ana amfani da ma'adanin sosai: kayan sun haɗa da hadakar, yashi wanda aka yi da na'ura, tururi na dutse, da tururi na gari. Idan akwai kayan aikin ƙauye, ana ba da shawarar a fitar da dukiyoyin saman farko sannan a yi amfani da tururin sa wajen rufi gini kafin samarwa ta al'ada, wanda zai rage yawan zafi na yashin da aka yi da na'ura.
2. Tsarin yana amfani da hanyar yin kwaya mai bushewa. Hadakar da yashin da aka yi da na'ura suna da ƙananan abun ruwa (yawanci ƙasa da 2%).
