4 Discussion
The decision tool aims to help the design team to implement more sustainable
recycling pathway. It is not a matter of providing a comprehensive assessment for
each recycling pathway during the design phase, but it is to communicate to
industrial customers the performance indicators in addition to the economic indicators. These additional performance indicators should allow designers to propose
optimization on recycling pathways and give a quantified result of the improvements. With an iterative approach, designers could optimize the flows and processes
to contain impacts.
Although recycling process lines are not new, industrial optimization has not
been fully conducted yet [25]. The unconstructive approach, the complexity of
waste and the lack of control over incoming flows limit the drafting of theoretical
principles. The increasing interest in waste recycling and the evolving regulations in
force steer the waste sector to adopt an increasingly industrial approach. In order to
support this transition, it is a question of advancing the design methods with
specific tools.
5 Conclusion
Even though plenty of technical options exist for developing recycling products, the
recycling solutions selecting motivations are too often led by the pursuit of profit
growth which leads to a greater inefficiency [26]. By communicating additional
performance indicators, we are convinced that this approach can evolve. And that
new issues will be introduced in trade negotiations for recycling pathway.
As a next step, we need to build a sufficiently complete and robust database to
support the evaluation of recycling pathway. This approach must be enriched in the
future. It is also required to facilitate the improvement of the quality of results
during the refining process variables and input parameters.
