Abstract:
Organic waste represents an issue that needs to be solved in
order to achieve sustainable development. In Romania, organic waste
(biodegradable) represents almost half from the household waste
composition. The waste management in Romania is characterized by the
continued growth of waste quantities and landfilling continues to be the
main elimination method for solid waste. Composting and anaerobic
digestion are two solutions for reducing of organic waste landfilled. In
this paper life cycle assessment (LCA) methodology was applied to
determine and evaluate the environmental impact of composting system.
All LCA phases were performed: goal and scope definition, inventory
analysis, impact assessment and interpretation. Two LCA tools were
used for the evaluation: GaBi software and Life Cycle Assessment -
Integrated Waste Management Assessment Tool. The results reveal that
the quantity of waste composted and the type of waste are influencing
the environmental impacts values.
