Design for Disassembly in the Age of Circularity
Design for disassembly, a practice embraced by product developers, plays a crucial role in fostering a circular economy. By dismantling and repurposing original components, whether within the same product or an entirely new one, substantial environmental advantages can be achieved.
It used to be easy to fix things when they were designed to be fixable. These days, it is hard to disassemble, let alone repair, them due to linear production practices, lower product costs and evolving manufacturing technologies. While industrial transformations have enabled speed-to-market, they have also increased manufacturing waste across the globe. Think abandoned aircraft parts(1), household electronic equipment(2) and wind turbine blades with poor recyclability – all unaccounted for and growing in number.
With all this waste expected to reach 3.4 billion tons by 2050(3), manufacturers and operators must focus on making their product values more circular – to rethink their approach to product design and make parts and components easier to dismantle, recycle, reassemble and upgrade. Prioritizing disassembly will also enable them to reduce waste, repurpose extracted materials and decarbonize their value chain. In most cases, disassembling products consumes less energy than grinding and melting materials for recycling.
Designing for disassembly is a greater challenge than designing for assembly. Subcontractors are often the ones doing disassembly at non-centralized sites, while retaining the value of components and materials is often difficult and costly. Simulation and other digital capabilities on the 3DEXPERIENCE platform enable manufacturers and operators to design the disassembly processes right from the early stages of product development.

Turn to powerful digital solutions on a fully integrated platform to optimize your disassembly strategy and claim your place in the global circular economy.
Advantages of Design for Disassembly
By creating products that can be easily dismantled, reused, or recycled, DfD helps manufacturers reduce environmental impact while maximizing resource efficiency. This methodology not only aligns with circular economy principles but also delivers tangible benefits for businesses, consumers, and the planet. Below are the key advantages of adopting a design for disassembly strategy:
- Minimizes Waste
Simplifies recycling and repurposing, reducing landfill contributions. - Conserves Resources
Enables recovery and reuse of materials, cutting down on resource extraction. - Saves Energy
Disassembly uses less energy compared to traditional recycling methods. - Extends Product Lifespan
Allows for repairs, upgrades, and part replacements, maximizing longevity. - Supports Circular Economy Goals
Encourages reuse and recycling to promote sustainable business practices.
Disassembly: A Step Closer to Circularity
To repurpose and remanufacture product parts for further use, a good recovery system must first exist. On the 3DEXPERIENCE platform, manufacturers and operators can track and oversee dismantled components and materials in one place before taking them further in the disassembly process.

Understand Your Supply Network
Integrating an end-to-end disassembly strategy into a circular economy framework can be complex. It is far easier for manufacturers and operators to pinpoint and develop the circular values of their strategy when they can trace where all product parts, components and materials are within their value chain.

FAQ About Design for Assembly and Disassembly
Design for Disassembly (DFD) promotes products designed for easy disassembly and recycling. It considers the entire lifecycle during design, prioritizes recyclable materials, and enables effortless part removal for reuse or recycling.
Design for Disassembly (DfD) in construction and architecture is a sustainable design approach that focuses on creating buildings and structures that can be easily dismantled at the end of their lifecycle. This allows for the recovery, reuse, or recycling of materials and components, reducing waste and environmental impact. By using reversible connections, modular designs, and traceable materials, DfD supports circular economy principles, extends the lifecycle of building materials, and promotes flexibility for future modifications or relocations.
Designing for disassembly (DfD) involves creating products or structures that can be easily taken apart for reuse, recycling, or repurposing. Here are the essential steps to follow:
- Simplify Component Connections: Use standardized, reversible fasteners like screws instead of adhesives or welding.
- Select Sustainable Materials: Choose materials that can be easily separated and recycled without contamination.
- Enable Easy Access: Design products to allow straightforward disassembly with common tools or automated systems.
- Incorporate Modularity: Create modular components that can be individually replaced or upgraded.
- Use Digital Simulation Tools: Leverage platforms like the 3DEXPERIENCE to model and optimize disassembly processes during product development.
By prioritizing these strategies, manufacturers can reduce waste, streamline recycling, and extend product lifecycles.
Design for repairability ensures products are created to be easily repaired, extending their lifespan and reducing waste. This approach involves:
- Modular Design: Designing parts or modules that can be individually repaired or replaced.
- Accessible Components: Ensuring critical components are easy to reach without requiring extensive disassembly.
- Standardized Parts: Using common, widely available components for cost-effective repairs.
- Clear Documentation: Providing repair manuals or digital guides to assist users and technicians.
Repairability not only supports sustainable practices but also enhances customer satisfaction and loyalty.
Design for deconstruction refers to creating buildings, structures, or products that can be easily dismantled for reuse, recycling, or repurposing. Key features include:
- Reversible Connections: Utilizing bolts, clips, or screws instead of permanent adhesives or welds.
- Material Recovery: Selecting materials that retain value and can be reused without degradation.
- Component Traceability: Implementing digital passports to track materials and components throughout their lifecycle.
- Circular Design Thinking: Prioritizing designs that facilitate end-of-life material recovery and reintegration into new projects.
This approach is essential for promoting sustainability in construction and other industries.
