PROs
Requires less area
Allows better management of emissions / odors
Allows recovery of energy (biogas)
Fuel for vehicles
CONs
High costs (investment /management)
More sofisticated and sensitive technology
Requires high input quantities
Requires homogeneous input
More adequate for industrial scale
PROs
Simple, robust technology
Flexibility (capacity/modules)
Biological process less complicated
Process allows and requires input of woody
materials (green waste)
Lower costs (investment/management) than AD
CONs
Slower process
Generation of odours if not managed well

Recommendations:
Establish criteria for implementation plans in legal dispositions.
Subject subsidies to feasibility studies (staff capacity, contracts,
etc.).
Consider home‐composting in small villages and areas of
difficult access.
Charge higher disposal tax in absence of implementation plan.
Establish legal obligation for separate collection in the
commercial and industrial sector.
Be patient! Slowly but surely does the trick!
