Economic aspects

AWAST WP 3

12 – 13 février 2001 – Cemagref / ISWA

Objectives

Providing the economic aspects of the decision support system which will help decision makers to know which kind of system should be developed, respective of the local conditions.

A more accurate undestanding and control of municipal waste management service costs will be available and proposed to decision-makers.

Help waste management authorities maximize long term efficiency of MSW management system by minimizing its costs.

Methodology

Identify and inventory of the types of costs to take into account within a process standardisation between facilities to allow the global approach

Definition of parameter models by facility Data acquisition on site in order to test each model of facility Processing of available and newly acquired data (data

standardisation according to the matter description defined) Calibration and validation of the models (models for each activity and for the global system)

Work description

Task 1 : state of the art and data acquisition(Month 3 to 24)

Task 2 : definition of production cost models(Month 6 to 14)

Task 3 : calibration and validation of the models(Month 13 to 19)

AWAST WP 3

12 – 13 février 2001 – Cemagref / ISWA

Task 1 – State of the art and data acquisition

Direct costs compents will be obtained for defined models from : litterature review, partners of AWAST, members of steering committee.

Calibrating the production cost models will be done through data collection in cost centres of the cities where plants are being studied by partners.

12 – 13 février 2001 – Cemagref / ISWA

Task 2 – Definition of production cost models

Development of a standard analytical structure for calculating the production costs of each facility (collection, sorting, composting, incineration, landfill)

Aggregation of units costs in order to obtain the total cost of the system for different waste flows in MSW management

Determining the full cost of MSW service by taking indirect costs of local authority management

AWAST WP 3

12 – 13 février 2001 – Cemagref / ISWA

Task 3 – Calibration and validation of the models

Calibration of the models and simulation of several scenarii in relation with WP 7 – WP 8

Validation by application on cases studies in WP 9
