Then, they were examined for possible biodegradation.
The mixture consisted of leaves, paper waste, cow manure,
food waste, composting seeds, urea, wood waste and water
(Mu¨ller, 2005). The mixture was kept in an oven at 55 C, at
which the maximum growth of thermophilic microorganisms
occurred. The samples were weighed every three days in order
to determine the percentage of weight loss.
