Avoids the use of hazardous substances, such as toxic chemicals or heavy metals, that can harm human health and the environment
Promotes the use of bio-based materials, such as plant-based plastics or mycelium composites, that are derived from renewable resources and have a lower carbon footprint than petroleum-based materials
Emphasizes the importance of resource efficiency, such as using materials that are lightweight, durable, and require minimal maintenance, to reduce the overall resource consumption of products
Design Strategies for Longevity
Focuses on creating products that are built to last, easy to repair, and upgradable to extend their useful life and reduce waste
Involves designing products with durable materials and construction techniques that can withstand wear and tear over time
For example, using high-quality, corrosion-resistant metals or reinforced plastics for outdoor furniture to ensure long-term durability
Incorporates modular design principles, such as standardized components and easy-to-replace parts, to facilitate repairs and upgrades and reduce the need for complete product replacement
Provides clear instructions and resources for product maintenance, such as user manuals, spare parts, and repair services, to empower consumers to keep their products in good working condition
Considers the aesthetic and emotional durability of products, such as timeless designs and personal customization options, to encourage users to keep and cherish their products for longer
Explores innovative business models, such as product-as-a-service or leasing, that incentivize companies to design products for longevity and provide ongoing maintenance and support
Promotes the use of digital technologies, such as predictive maintenance and remote diagnostics, to monitor product performance and prevent premature failure
Circular Economy Integration
Aims to create a closed-loop system where resources are kept in use for as long as possible, waste is minimized, and materials are recycled or regenerated at the end of their life cycle
Involves designing products that are easy to disassemble, repair, and recycle to facilitate the recovery and reuse of materials
For example, using snap-fit joints instead of adhesives for product assembly to enable easy disassembly and material separation
Encourages the use of renewable and biodegradable materials that can be safely returned to the biosphere at the end of their life cycle
Promotes the development of reverse logistics systems and infrastructure to collect, sort, and process end-of-life products for recycling or remanufacturing
Explores innovative business models, such as product-as-a-service or sharing platforms, that prioritize access over ownership and reduce the demand for new products
Fosters collaboration among stakeholders, such as designers, manufacturers, recyclers, and consumers, to create a shared vision and responsibility for circularity
Leverages digital technologies, such as the Internet of Things (IoT) and blockchain, to track and optimize the flow of materials and products throughout the circular economy
Life Cycle Analysis
Systematic approach to assessing the environmental impacts of a product or service throughout its entire life cycle, from raw material extraction to end-of-life disposal
