Design for Disassembly: Breaking the Take-Make-Waste Product Cycle

Only nine percent of all plastic produced has ever been recycled, as per a 2017 study in Science Advances by the University of California. This percentage has not seen improvement since that time. Known as the 10% Rule, it highlights that products designed with conventional methods today have less than a one-in-ten chance of being recycled.

This 10% Rule isn’t dictated by physics; it’s a result of design choices found in every glued seam and multi-material composite, as well as in products lacking an end-of-life plan. Design for Disassembly (DfD) aims to change this by focusing on end-of-life separation right from the product development stage.

Understanding the shortcomings of the current system and envisioning a better alternative is crucial for those concerned about where products end up once they leave our homes.

The Built-In Disposal Problem

Consumer products often consist of multiple materials that are bonded in ways that make end-of-life separation costly or even unfeasible.

• Smartphones include over 60 elements from the periodic table, often in amounts too small to be economically recoverable.
• Standard mattresses combine polyurethane foam, steel springs, fabric, and chemical flame retardants in a way that makes disassembly more costly than the materials’ value.
• Drip coffee makers are made of materials like polypropylene, ABS plastic, and stainless steel, permanently joined by ultrasonic welding.

This results in what the EPA defines as municipal solid waste, a vast stream of recoverable materials made unrecoverable by design. The U.S. recycling rate for municipal solid waste is around 32%, but this number doesn’t reflect the lower rates in specific product categories. According to the UNEP Global E-Waste Monitor, global electronics recycling is about 17%. Plastics fare even worse, illustrating that the 10% Rule is a common state of recyclability, not an anomaly.

The main issue isn’t contamination in recycling bins; it’s that products were never designed to be recovered. Material recovery simply wasn’t a design priority.

What Design for Disassembly Actually Means

DfD considers end-of-life separation as essential as cost, performance, and aesthetics in product design. The objective is for every material in a product to be identifiable, accessible, and separable without damaging adjacent components.

In practice, DfD involves decisions that might seem minor individually but have a significant impact over a product’s lifespan and the economy:

• using a single material per component where feasible;
• opting for mechanical fasteners instead of adhesives;
• choosing snap fits or standard screws over welded joints;
• embedding material identification codes directly into plastic parts; and
• designing modular architectures that allow for component-level replacement instead of whole-unit disposal.

The Ellen MacArthur Foundation sees DfD as a key strategy for maintaining products and materials at their highest productive value.

DfD also involves a business model decision. The design offers its full value only if the manufacturer has an incentive to retrieve the product, whether through producer responsibility obligations, take-back programs, or remanufacturing operations that make recovered materials economically viable.

Design, collection, and economics must align to make circularity profitable.

Where It Works: Examples From Practice

Some companies have shown that DfD at a consumer level is not just a concept but a reality.

Fairphone, a Dutch electronics company, designs its phones so users can replace the battery, screen, and camera with common tools. iFixit gives Fairphone high repairability scores, most recently a “10” for its Fairphone 6. The commercial rationale is clear: a longer-lasting phone keeps customers engaged and valuable materials out of waste.

Caterpillar’s remanufacturing program, one of the largest industrial DfD efforts, reclaims used engines, hydraulic components, and transmissions, restoring them to original specifications for resale. This significantly cuts both energy use and raw material needs compared to new manufacturing.

Herman Miller’s Aeron chair features material identification on every part, easy disassembly paths, and a take-back program. The company claims a high recyclability percentage by weight, achieved through feasible design separation.

These examples prove that the 10% Rule isn’t inherent to manufacturing itself but to the absence of DfD practices.

The Household Math

What does the 10% Rule mean for a typical household? Americans discard millions of smartphones annually, each containing small but valuable quantities of gold, palladium, cobalt, and rare earth elements that can only be recovered if the product design allows for separation. These materials hold real economic value but are only recoverable if the product is built to release them.

This logic also applies to appliances, power tools, mattresses, and furniture, which make up the bulk of household material consumption. When a washing machine ends up in a landfill because it can’t be repaired and wasn’t designed for disassembly, valuable materials like steel and copper are lost to the productive economy.

The financial impact on households is significant: the inability to repair shortens product lifespans and increases lifetime costs. A phone designed for a $50 battery replacement versus a $600 new device is not just an environmental issue but an economic one. The U.S. PIRG Education Fund estimates that right-to-repair policies could save consumers up to $49.6 billion annually in reduced replacement costs.

The Upstream Argument

DfD isn’t just about waste; it’s also about virgin material extraction. Every ton of aluminum recovered through disassembly means a ton less bauxite needs to be mined. Aluminum recycling consumes about 95% less energy than primary production, according to The Aluminum Association. Steel recovery saves over 60% of the energy required to produce steel from iron ore, says the World Steel Association. Copper recovery is similarly beneficial. These figures show how recycled-material markets become economically viable when the supply is clean and separated, which DfD facilitates.

The design choices made during a product’s development determine whether these upstream savings are feasible downstream. DfD shifts the intervention point to where it belongs: before the product is created, not after it fails.

What You Can Do

Individual actions:

• Opt for repairable products. iFixit provides repairability scores for electronics; consider them like a car’s mileage rating.
• Utilize manufacturer take-back programs. Apple, Dell, and Best Buy all offer take-back and recycling services, sending products to a designed recovery stream.
• Repair items before replacing them. Fixing appliances can extend their life by years. Earth911’s recycling search can help find repair services and drop-off options for hard-to-recycle items.
• Buy modular products when possible, such as those with user-replaceable batteries, accessible components, and standard fasteners. These features characterize a well-made product.

Community and policy levers:

• Support extended producer responsibility (EPR) laws in your state. EPR laws make manufacturers fund the end-of-life management for their products, making DfD economically viable for companies that might not choose it otherwise.
• Advocate for right-to-repair legislation. The FTC’s 2021 report to Congress on right to repair highlighted the consumer and environmental benefits. Laws requiring manufacturers to provide parts and repair information have passed in several states, with more pending at state and federal levels.
• Inquire about take-back programs when purchasing durable goods. Buyer demand can influence procurement decisions over time.
