| description | Composting is recognized as a sustainable waste management approach in which
microorganisms treat and stabilize biodegradable waste under aerobic
conditions to obtain compost as a final product. In this paper, composting
of biowaste in a rotary drum composter (closed system) and an open container
(open system) was compared. Temperature, pH, electrical conductivity, a
carbon-to-nitrogen mass ratio (C/N ratio) and contents of moisture, carbon
and dry and volatile matter, were measured during composting. Results showed
decreasing profiles for moisture, volatile matter, and carbon contents, as
well as for the C/N ratio, while increasing profiles for the dry matter
content and electrical conductivity during composting in both systems.
Leachates were formed only during the first three days of composting and
were characterized with high organic loads, high ammonia concentrations, low
pH, and high conductivity and turbidity. The organic matter content data
during the composting process were analysed according to the first order
kinetic model. Results suggested that there was a difference in the rate of
organic matter decomposition, which was higher when composting in the open
vessel than in the rotary drum composter. |
