Ecodesign and the use of sustainable materials is important for designers to consider. Designers have tools to design for recyclability, closed-loop systems, and to avoid toxic materials. They can also ensure durability and use materials intelligently. Sugru is a silicone material that allows users to repair items instead of replacing them. It bonds well and is flexible, waterproof, and heat resistant. Treeplast is a biocomposite made of wood chips, corn, and resin as a natural alternative to plastics. It can be injection molded but takes longer to cool and needs lacquer finish for water resistance.

- 1. 01 Introduction Making it... Designers have responded to these emergent issues through the development of design Materials Databases approaches such as ecodesign and design for sustainability. Materials and the interaction Designers have the tools to design between materials and design is a recycled content into products, key issue in ecodesign. It is already design for recyclability and apparent that the consequences closed-loop product systems, of our resource use, in terms of design out toxic or hazardous environmental impact, are materials, and to ensure the unsustainable. Design has a durability of products. Ecodesign powerful influence on how people thinking addresses a company’s consume and use products. This materials, processes and influence includes the types and practices and aims to design out quantity of materials consumed, waste. Importantly ecodesign how the consumer responds to the thinking also identifies value and materials and what happens to opportunity in the use of more those materials when they have sustainable materials and reached the end of their useful life. preventing “legacy waste” This places a greater responsibility problems for future generations. on the designer to use materials in an intelligent way. The challenges posed by Forward by Simon O’Rafferty sustainability require us to innovate. Ecodesign Centre

Love What You Own It finds application as a sculptural material, for creating personal Sugru is a silicone elastomer additions to products (customized modelling material.
