Making uplas/logs by hands using cow dung is a traditional activity followed in rural India. These uplas are used as fuel and manure. Indian people mostly prefer traditional product for cremation e.g. wooden logs and dried cow dung logs. Also, cremation using cow dung logs costs less as compared to fire wood or electricity or LPG gas. This lead to more demand of cow dung uplas/logs day by day, combined with the reluctance on part of the today’s educated generation to get their hands dirty, which led Shri Arjunbhaifrom Gujarat to develop a machine that makes long cow-dung logs and uplas with minimum human intervention.
A combination of dung and straw (or any agri waste of harvested produce) is mixed and fed into the hopper which is filled in the middleframe of the machine. Thismixture is then pressed betweentwo plates as a result of which it takes the shape.These die-sets are then opened by hand operated lever to leaving the logs/uplas on the bottom plate. The logs thus made are then put in the sunlight to dry out the moisture inside, making them dry and hard.
