10.1.5. Sustainable product design

Efforts should be made to design a product with fewer amounts of hazardous materials. For example, the efforts to reduce material use are reflected in some new computer designs that are flatter, lighter and more integrated. Other companies propose centralized networks similar to the telephone system.

This chunk emphasizes the need to reconsider how products are designed. Designers should aim to create products that use fewer hazardous materials and reduce their environmental impact. An example of this is seen in newer computer designs that are flatter and lighter, which implies they use fewer materials. Flatter designs not only save materials but can also lead to more efficient transportation and storage.

Imagine packing for a trip; if you can pack your clothes in vacuum bags to reduce space, not only will your luggage be lighter, but you'll also be able to carry more with less hassle. Similarly, if electronic products are designed to be more compact and integrated, they reduce the need for excessive materials and energy in production.

Bio-based plastics are plastics made with plant-based chemicals or plant-produced polymers rather than from petrochemicals. Bio-based toners, glues and inks are used more frequently. Solar computers also exist but they are currently very expensive.

This chunk discusses the importance of using renewable materials in product design. Bio-based plastics, for example, are sourced from plants rather than traditional fossil fuels, making them more sustainable. Although products like solar-powered computers are emerging, their high cost can be a barrier to widespread adoption.

Consider the difference between using a regular type of plastic bottle and a bottle made from sugarcane. The sugarcane bottle reduces reliance on oil and is more environmentally friendly. Though such innovations may be pricier initially, over time they can lead to a healthier planet.

Because many of the materials used are non-renewable, designers could ensure the product is built for re-use, repair and/or upgradeability. Some computer manufacturers such as Dell and Gateway lease out their products thereby ensuring they get them back to further upgrade and lease out again.

This chunk highlights a strategy for using non-renewable materials more responsibly by designing products that can be reused, repaired, or upgraded. For instance, companies like Dell and Gateway choose to lease products instead of selling them outright. This approach allows them to collect the devices back after use to refurbish and lease them again, which can significantly extend the product's lifecycle.

Think of a book from a library. Instead of purchasing a book to own forever, borrowing it allows many people to enjoy it over time without needing new copies. Similarly, leasing a product maximizes its utility and reduces waste.
