Targets of MBP
� reduction and stabilization of OS� better input-control at landfills� reduction of gas generation� reduction of leachate (amount and
concentrations)� lower consumption of landfill volumes� lower settlement� reduction of harmful substances� use of thermally valuable compounds.
Erwin Binner Biowaste Workshop 2002
Waste Reactivity Assessment
� parameters describing the stability ofMBP-waste
� test methods for MBP-waste.

Experiences in AustriaImpact of MBP on Landfill Behavior
Reservations:� input to MBP = municipial solid waste
(not residual waste)� different legal situation
(no MBP-Guideline, no limit values)� no landfill with exclusivly MBP waste
(20 to 80% MBP mixed with MSW, bulky waste,comercial waste, in some cases green wastes)
� different technical standards(no gas collection, different leachate collectionsystems)

Laboratory TestsImpact on Geotechnical Properties
� higher compactability (1.3 t/m3, reduction of volume)
� lower permeability (10 -10 m/s, reduction of leachate)
� low particles size (< 15 - 35 mm, calorific value)
� problems in placement (rainfall)
� problems in stability (reduction of friction angle)< 12 mm → ϕ = 31°< 25 mm → ϕ = 32°< 40 mm → ϕ = 37°< 80 mm → ϕ = 40°
Erwin Binner Biowaste Workshop 2002
� reduction and stabilization of OS� better input-control at landfills� reduction of gas generation� reduction of leachate (amount and
concentrations)� lower consumption of landfill volumes� lower settlement� reduction of harmful substances� use of thermally valuable compounds
