elastsust

Elastsust is a term used to describe materials and design strategies that aim to maximize elastic performance while reducing environmental impact over a product's life cycle. Materials labeled elastsust typically show high elastic recovery, resistance to permanent deformation under cyclic loading, and potential for recycling or safe end-of-life handling. The concept blends elasticity science with sustainable materials design and life-cycle thinking.

Origin and scope: The term appears in interdisciplinary discussions since the early 2010s and is used as a design philosophy rather than a fixed standard. It can apply to polymers, composites, and hybrid systems when the balance of performance and sustainability is central to the choice of materials and manufacturing.

Key approaches include selecting recyclable matrices and bio-based or recycled content, using reversible cross-links or thermoplastic matrices for recyclability, and designing for disassembly and repair. Life-cycle assessment and performance metrics are used to compare alternatives and guide material selection.

Applications include cushioning and vibration isolation, automotive and aerospace components, footwear and sporting goods, medical devices, and building materials—areas where repeated deformation and sustainability concerns intersect.

Challenges involve trading off stiffness, strength, and durability with recyclability, developing standardized elastsust metrics, and ensuring cost-effective supply chains. Ongoing research seeks tunable elasticity coupled with high circularity through advanced polymers, composites, and processing methods.
