Slide 1

JP1 Présentation du concept de l’ÉIPrésentation des notions de synergies de substitution et de mutualisation et comment est-ce que ces concepts peuvent servir à atteindre les objectif québécois en gestion des matières résiduellesPrésentation de cas québécois

Au sein des 3 projets de symbioses que vous avez réalisés(ou autres projets), y a-t-il eu des synergies de mutualisation ? Je sais qu’en France de nombreux parcs industriels ou zones d’activités ont mis en place des collectes mutualisées de certains flux (papier, carton, TIC, etc.), cela pourrait être pertinent de présenter le « comment ».Jennifer Pinna CTTEI; 16/09/2013

Québec is known for…

Rather soft environmental regulations

Low landfill cost

Well established recycling circuits

But also for…

Why bother then?

� Upcoming regulations

� Some wastes gradually banned from landfill, waste reductionobjectives

The many challenges of innovation

� Small and dispersed volumes

� Resistance to change

� Industrial know-how to protect

� Lack of time, budget and resources

� Short-term concerns (while changing practices is

usually done in the longer term)

� Facts� Waste properties� Physico-chemical analysis� Volumes, frequency, etc.

� State of the art� Technical litterature, patents, etc.

� Best available technologies

� Brainstorming!

� Technico-economical feasibility study

� Solutions priorization

� Implementation� Product development� Technology transfer

…and a methodology

� Simple processes are preferred

� Mechanical solutions preferred over

chemical options

� Development of useful products

� Optimized use of local ressources

� Plan the products’ end-of life

� Economically feasible

Can it be sustainable too?

� Focus on their immediate needs

� Minimise the impact on their current

operations

� Rapid and low-cost implementation, ideally

by a third-party

� Demonstrate the gains

� Help for funding

� Easy to implement

The clients’ criteria
