Fig. 3 shows the global composition of the MW at the UJI. The
fact that, of the total MW generated annually, 58% in weight corresponds
to the canteens and 42% to the cleaning service has been
taken into account. This figure also shows that 45.83% in weight
of the MW corresponds to organic matter coming mainly from
the canteens, followed by dirty paper (26.03%) used to dry hands
from the cleaning services and, finally, plastics (12.44%). The
minority fraction is formed by the inert waste. These results are
comparable to other studies, in which the greatest fractions were
also paper-cardboard and organic matter waste (Taghizadeh
et al., 2012; Smyth et al., 2010).
