Begin at both ends
Set out what is known about the incoming material and what the intended user requires. Keep those two descriptions alongside each other as the project develops.
A list of available waste streams is a starting point. A project brief also needs to describe the intended use, the preparation requirements and the information still needed to assess the fit.
Map the interfaces
Collection, sorting, storage, transport and industrial use each introduce responsibilities and constraints. A simple process map helps the parties agree who provides which information and where a specification needs to be defined.
Compare complete routes
When comparing options, define the same boundary for each route. Include the preparation steps, handling arrangements, operating assumptions and commercial responsibilities that belong inside it.
Make uncertainties visible instead of hiding them inside a single headline estimate.
Create a shared basis for the next step
A productive early output is a requirements matrix: what the material assessment needs to establish, what the receiving user must confirm and what the project team should test before proceeding.
That shared brief can guide the feasibility work, procurement discussions and implementation planning.
A general discussion guide, not a site-specific engineering assessment. The right approach depends on the project and its operating context.
