ADOS System

The ADOS System (Anaerobic Digestion of Organic Slurry) is the full process for converting organic waste to biogas, which combines the advantages of the wet and dry digestion techniques and uses a slurry consisting of ~ 15% solids. It converts organic wastes into biogas, heat and electricity and is the most efficient system for the treatment of organic waste derived from separately collected or source-sorted waste. It is also highly suitable for mechanically separated organic fractions from unsorted MSW. The sedimentation and recirculation of digestate are adjusted for different feedstocks to provide the optimum slurry consistency. Typical feedstocks are: 
  • Mechanically separated fraction (<60mm) of unsorted municipal solid waste
  • Household, restaurant, commercial kitchen waste
  • Agricultural waste
  • Slaughterhouse waste, markets and processing industries 
The feedstock requires simple pre-treatment removal of ferrous metals and inerts before passing through the specialist ADOS mill to create the optimum slurry conditions for the subsequent processes of sedimentation, digestion and biogas production. Feedstock containing animal by-product waste materials requires prior hygienisation treatment. 
For the implementation of a project in Singapore using the ADOS solution, the IUT group was  awarded the national Energy Globe – World Award 2007 for Sustainability.
