Design for Sustainability and a Circular Economy

Datschefski's five principles of sustainable design

Five principles that facilitate a holistic approach to sustainable design.

Cyclic

The product is made from organic materials, and is recyclable or compostable, or is made from minerals that are continuously cycled in a closed loop.

Solar

The product uses solar energy or other forms of renewable energy that are cyclic and safe, both during use and manufacture.

Safe

The product is non-toxic in use and disposal, and its manufacture does not involve toxic releases or the disruption of ecosystems.

Efficient

The product's efficiency in manufacture and use is improved by a factor.

Social

The product and its components and raw materials are manufactured under fair and just operating conditions for the workers involved and the local communities.

Sustainability

In the context of design, sustainability seeks to eliminate a negative impact on the environment, health and well-being of users.

Triple bottom line (TBL)

A product or system is only considered sustainable if it meets all three pillars: economic (profit), environmental (planet) and social (people).

Biodegradable material

A material that will decompose into basic substances in the environment over time

Circular economy

An economic model in which resources remain in use for as long as possible, and materials are recovered and regenerated at the end of life (made to be made again)

Dematerialization

The reduction of total material and energy throughput of any product and service.

Linear approach/economy

An economic model that follows a take—make —dispose approach, leading to depletion of resources and waste.

Renewable energy sources

A natural resource of energy that can be replenished with the passage of time or that does not abate at all.

Take-back legislation

Laws that require manufacturers to “take back” products at the end of their life for disposal or recycling. Also known as “extended producer responsibility”.

Decoupling

The process of disconnecting economic output from environmental impact
