Enhancing Laptop Sustainability

The Problem of Electronic Waste and the Impact of Laptops

In recent years, electronic waste has become one of the most significant environmental challenges. With increasing production scales and a fast-paced consumption culture, the number of laptops is steadily rising, leading to a corresponding increase in waste generation. The complex disassembly of devices complicates both recycling and repair, resulting in higher costs, wasted resources, and lost opportunities to extend the lifespan of devices.
One of the main obstacles is the inconsistency of fasteners and their varying standards. To address this issue, researchers Y. M. Khan, T. F. Go, V. C. Tai, L. K. Moey, L. S. Ngow, D. A. Wahab, and W. S. Yap present an innovative approach in their study „Enhancing Fastener Standardization for Disassembly: A Path to Sustainable Laptop Design”: the implementation of standardized fasteners. This method facilitates disassembly, shortens repair times, and reduces environmental impact, as components become easier to replace, upgrade, and recycle.

A More Efficient Product Concept that Reduces Waste

Traditional laptop manufacturing often lacks a structured approach focused on easy device disassembly. This leads not only to increased waste but also to difficulties in repairing or recycling older devices. By implementing design for disassembly (DfD), the efficiency of component recycling can be significantly increased, repair costs can be reduced, and systematic contributions to environmental protection can be made.
The European Union’s Circular Economy Action Plan (2020) emphasizes the need to create durable, easily upgradable, and disassemblable products. Additionally, recycling and remanufacturing processes can reduce production costs by 40-60%, while consuming fewer materials and energy. Therefore, an integrated DfD approach is a key step towards a more sustainable technological future: it promotes modularity, simpler maintenance, and longer device lifecycles.

Example: How the Implementation of Standardized Fasteners Simplifies Disassembly

The study analyzes the typical laptop disassembly process, where traditional design solutions create numerous problems. Different types of screws and other fasteners require the use of multiple tools, extending disassembly time, increasing repair costs, and complicating recycling.
In practice, obstacles arise from: hidden or differently sized screw heads, excessive adhesives and tapes, fragile fasteners, as well as unmarked or inconsistently placed fastening points. As a result, operations such as removing the screen and keyboard become complicated, slow, and risky for damaging parts. The implementation of standardized fasteners offers a practical solution: reducing the number of required tools, clearly marking fastening points, and speeding up the entire disassembly process.

An Innovative Solution Promoting Efficient Repair Processes

One of the key aspects of the study is the implementation of standardized fasteners. Traditional models often use various types of screws, requiring different screwdrivers and even specialized tools for a specific device. It is proposed to design computers using only two types of screws:

• M2.5×25 flat head screw – used for securing the screen, ensuring a stable and secure connection.
• M2.5×3 flat head screw – used for securing the keyboard and other essential components.

By applying this principle, technicians need only one common screwdriver. This simplifies assembly and disassembly, reduces the likelihood of errors, speeds up work, and increases modularity – parts become easier to replace, and the device’s lifespan naturally extends. Ultimately, electronic waste decreases, as more components can be reused or recycled.

Digital Data: How Standardization Speeds Up Work

To objectively assess the advantages of the proposed design, a comparative analysis was conducted between traditional laptop designs and the new standardized solution:

• Screen removal time: the traditional design required about 60.48 seconds, while the new one only takes 14.78 seconds (approximately −75.6% time).
• Keyboard removal time: in the traditional design, this process took about 121 seconds, while in the standardized version, it takes only 26.88 seconds (approximately −77.8% time).
• Number of required tools: the traditional design needed three different screwdrivers, while the new solution requires just one (approximately −66.7% tools).

The results clearly show that the implementation of standardized fasteners significantly accelerates disassembly, reduces repair and recycling costs, and increases the availability of components in the future. Furthermore, a smaller variety of tools simplifies work for service centers and shortens employee training time.

Standardized Fasteners as a Driver of Sustainable Solutions

Standardized fasteners not only facilitate technical maintenance but also strengthen the principles of sustainability and the circular economy. Easy disassembly encourages repair over new purchases, thereby extending the lifespan of devices and reducing waste.
Easier-to-maintain and upgrade devices help reduce production and recycling costs, conserve raw materials and energy. By implementing DfD principles, products become more accessible to consumers, and organizations can create economically viable repair and upgrade models (e.g., parts replacement programs, secondary component supply chains). This creates added value at all stages of the product lifecycle.
