Environmental Categories
- There are three main environmental categories in the life cycle of a product.
- These affect every aspect of the products production, use and disposal.
Materials
- The materials a product is made of and how they affect the product and its sustainability.
- How easy or difficult it is to recycle or reuse a material.
- How difficult it is to obtain a material.
Energy
- The amount of energy required to make the product.
- The type of energy used to make a product.
Pollution/Waste
- The pollution caused by the making of a product.
- Waste when making a product, such as wasted materials or energy.
Sustainable Design Approaches
Green Design
- Designing in a way that takes account of the environmental impact of the product throughout its life.
- Focuses on only one or two of the three environmental categories.
- Materials
- Energy
- Pollution/waste
- Takes around 2 to 5 years to implement.
- Generally a few incremental and/or small radical changes on one or two of the environmental categories.
- Relatively easy to implement and cost-effective.
Considerations
- When evaluating a product, the designer must consider different green approaches to design, such as:
- Raw materials used
- Packaging
- Incorporation of toxic chemicals
- Energy in production and use
- End-of-life disposal issues
- Production methods and/or atmospheric pollutants.
Tools
- Green design uses the prevention and precautionary principles to reduce ecological impact.
Eco Design
- Similar to green design, but takes into account all 3 environmental categories.
- Takes around 5 to 10 years to implement.
- Small radical changes to all 3 of the environmental categories makes it more complicated than green design.
- Eco design has to consider all of the considerations of green design, as it targets all environmental categories.
Sustainable Design
- Designing physical objects and services in accordance with the principles of social, economic and environmental sustainability.
- Sustainable design uses the three triple bottom line principles:
- People (social)
- Planet (environmental)
- Profit (economic).
- Sustainable design generally takes around 10 to 20 years to implement.
- Relatively long due to several incremental and radical changes.
- Rethinks the nature of the product and how it may work.
- This extends the research and development (R&D) phase, and may not make it feasible to work within cost constraints.
Considerations
- When evaluating a product, the designer must consider the following sustainable strategies:
- Circular economy
- Clean technologies
- Triple Bottom Line sustainability
- Take-back policy
Tools
- Sustainable design takes into account the 5 principles of Datschefski, which are:
- Cyclic
- Solar
- Safe
- Efficient
- Social
Tools for Designers
The Prevention Principle
- The avoidance or minimization of producing waste in relation to the production, use and disposal of a product.
- The prevention principle aims to reduce the negative impact of a product.
The Precautionary Principle
- The anticipation of potential problems in relation to the environmental impact of the production, use and disposal of a product.
- The precautionary principle designs products in a way that ensures potential issues wont occur.
Datschefski's Five Principles
Cyclic
- The product is made from compostable, organic materials or from minerals that are recycled in a continuous loop.
Solar
- The product in use consumes only renewable energy that is cyclic and safe.
Safe
- All releases to air, water, land, or space are “food” for other systems.
- For example, dumping compost as waste could be considered "food" for nature, as it would naturally degrade it.
Efficient
- Requiring 90% less energy, materials and water than equivalent products in 1990.
Social
- Its manufacture and use support basic human rights and natural justice.
- No exploitation of workers.
