Fig. 1. Composition of the samples of OFMSW collected at different times without the ‘‘rejected materials’’ fraction. Data are reported as % on wet weight basis (a) and as % on
volatile solids (b).
Fig. 2. Average hydrogen and methane potential productions of the five single fractions and of the OFMSW samples. Dots represent the average value obtained from all tests,
bars indicate the standard deviation of all data. BP = bread–pasta; F = fruit; V = vegetable; MFC = meat–fish–cheese; U = undersieve 20 mm; OFMSW = organic fraction of
MSW.
Fig. 3. Hydrogen and methane potentials of OFMSW samples collected at different times. Dots represent the average value obtained from triplicate tests, bars indicate the
standard deviation of data
Fig. 4. Cumulative hydrogen (a) and methane (b) productions from average
experimental data (symbols) and from the mathematical model (continuous line)
for the three samples Mix A, Mix B and Mix C. Error bars represent the standard
deviation of experimental data.
