Start with the whole product life
A material choice is only one part of an environmental question. The US Environmental Protection Agency describes materials management across extraction, manufacture, use and end-of-life handling. For a design brief, that suggests asking where the product will be used, its intended service life and how it will be maintained. Record what is known and what needs evidence before comparing alternatives.
Make repair a design question
The Ellen MacArthur Foundation identifies keeping products and materials in use as a circular-design principle. A practical brief can translate that principle into questions: which parts might need replacement, who would do the repair, and how could they reach those parts? The answers depend on the product and its service arrangements. An accessible fastener alone does not establish a complete repair system.

Compare materials against a defined job
Begin a material discussion with the operating environment, mechanical requirements, appearance and intended manufacturing process. Ask for the data behind candidate materials, including any proposed recycled content. Record trade-offs and missing information. Environmental comparisons need a defined scope and evidence; a lighter component or a recycled-content label alone is not a complete assessment of a product.
Bring manufacturing intentions into the brief
Share expected production volume, process preferences, assembly requirements and available supplier information. A DFM/DFA review can examine the agreed part and assembly questions before you prepare the next set of files. Treat recommendations as design decisions to review against the actual supplier process. This review is not an environmental certification or a substitute for product testing.
What to prepare before starting
Gather the product purpose, intended users, existing drawings or CAD, known material information and the problems you want to resolve. Include any maintenance or replacement requirements, expected volumes and decisions still open. If a target is uncertain, say so. These inputs help us distinguish concept work, technical design, analysis and preparation of prototype or manufacturing files.

Common questions
- Does using recycled material make a product sustainable?
- Recycled content is one consideration. A useful comparison also considers the product’s function, manufacture, use and end-of-life handling, with a defined scope and supporting data.
- Which service is relevant if I want to improve an existing product?
- Product Redesign & Optimisation or DFM/DFA Review may be relevant. Select either in the brief, describe the current problem and include any available drawings, CAD or test findings. We review the inputs before agreeing the scope.
- Does prototype-ready design include a physical prototype?
- No. Prototype-ready Design supplies agreed design files and specifications. You arrange physical production separately.
- Can this article establish a product’s environmental performance?
- No. It helps frame a design brief. A claim about environmental performance requires suitable evidence and an assessment with a defined scope.
