Progress Meeting - Vienna - June 2001 Aid in the management and European comparison of Municipal Solid WASte Treatment methods for a global and sustainable approach. Fifth Framework Program Progress meeting Vienna, June 27-29, 2001 Progress meeting Vienna, June 27-29, 2001

Progress Meeting - Vienna - June 2001 Summary Project presentation Introduction to simulation concepts and terms Thematic WPs

Progress Meeting - Vienna - June 2001 AWAST general context The MSW management is a major problem for the local communities of the EU. The current situation: Lack of methodologies and softwares to: Ü Define, Ü Evaluate, ÜOptimise or adapt waste treatment decisions and to Ü Meet the EC level progress targets. The need: u Tools for modelling the effect of reduction, re-use or treatment of waste on the GLOBAL evaluation on MSW management

Progress Meeting - Vienna - June 2001 Conceptual layer - thematic approach Real world Conceptual model(s) Model for simulation  Images, ‘universal’ representations  for use to achieve objectives

Progress Meeting - Vienna - June 2001 Levels of models Types of models according to their use and cost of use TypeLevel Parameters Performance Predictive % in output(s) Use Flowsheeting Sizes, operating conditions no/few data on matter Id. level 1 + streams in/out real equipment Id. level 2 + laboratory characterisations Sizing/optimisation Optimisation Cost increasesPrecision increases

Progress Meeting - Vienna - June 2001 The heart of a simulator To represent the operation of each piece of equipment, we use a progressive approach, with several levels of models, more and more predictive…and costly to use, in the frame of the simulation methodology. Level 0: Percentage passing per category Level 0: Percentage passing per category Level 3: Size, operating conditions, Data from real operation, Physical properties Level 3: Size, operating conditions, Data from real operation, Physical properties Level 2: Size, operating conditions, Data from real operation Level 2: Size, operating conditions, Data from real operation Level 1: Size, operating conditions, Few or No Physical property Level 1: Size, operating conditions, Few or No Physical property Proportion of each category in the feed Size/shape of particles in each category …sampling, survey …sampling, survey + lab characterisation

Progress Meeting - Vienna - June 2001 For all modelling tasks 1. Definition of conceptual models  example of MFA/phase model  conceptual flowsheets  extraction of the flowsheet of Orléans 2. Extraction of practical model(s) of adapted level(s)  There are not bad models, but models adapted to an objective (case compost). Objective for simulation: “ Supplying a simulation tool to help in: The choice of suitable MSW treatment methods. The optimised management of processing (assessment, control, analysis of the existing situation). The optimisation of the installations.“l
