In this study, 6 main types of waste could be considered for
the Romanian case study namely: organic or biodegradable
waste, metals (ferrous and non-ferrous), glass, paper and
cardboard, plastic, and wood wastes. The data on waste
generation per these specific waste categories and treatment
options were available only for 2010 and 2012. Due to data
constraints, the use of CF aggregated models is preferred,
because they represent an efficient solution to obtain
information on the environmental impact, especially on the
air emission issues, as compared to other methodologies.
