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:Define,

Evaluate,

Optimise or adapt

waste treatment decisions and toMeet

the EC level progress targets.

The need:

Tools for modelling the effect of reduction, re-use or treatment of waste on the GLOBAL evaluation on MSW management


AWAST position and objective

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.

For all modelling tasks1. Definition of conceptual models

example of MFA/phase model conceptual flowsheetsextraction 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
