Reduced pH value in ecovio® bags decreases the microbiological activity and
provides conservation effect of organic waste. This leads to higher biogas potential.

5. Importance of compostable bags for
anaerobic digestion
5
Effects on biogas yield increase from using
ecovio® bags for kitchen waste collection by:
Volume increase of collected organic waste ~ 20%
► Berlin study, 2012
Higher calorific value ~ 10%
► Müll und Abfall, Kern study
Conservation effect up to 50%
► bifa study, 2015

ecovio® bags:
28,5 % composted,
27,5 % AD,
44 % incinerated

Ecologically best
solution for organic
waste collection is
ecovio® bag if all
organic waste is
treated in biogas
plants. Note: Anaerobic digestion (AD) technology considered in the
LCA study is dry fermentation with post-composting stage
