Why Design for Disassembly and reality sometimes are like oil and water. The idea behind Design for Disassembly (DfD) is straightforward—create products that can be easily taken apart for repair, recycling, or reuse. In practice, however, aligning this intention with the realities of manufacturing, costs, and the actual disassembly process is often a significant challenge. We try to sell the ideas whenever we see an opportunity, but it always fails due to one or more of the following reasons. 𝐂𝐨𝐦𝐩𝐥𝐞𝐱𝐢𝐭𝐲 𝐯𝐬. 𝐒𝐢𝐦𝐩𝐥𝐢𝐜𝐢𝐭𝐲 Designs optimized for disassembly can add complexity to production. For example, replacing permanent adhesives with mechanical fasteners may make repairs easier but complicates development and assembly processes. 𝐌𝐚𝐭𝐞𝐫𝐢𝐚𝐥 𝐂𝐡𝐨𝐢𝐜𝐞𝐬 While single-material designs are ideal for recycling, real-world performance requirements often necessitate multi-material solutions or composites, making separation at the product's end of life more difficult. 𝐄𝐜𝐨𝐧𝐨𝐦𝐢𝐜 𝐏𝐫𝐞𝐬𝐬𝐮𝐫𝐞𝐬 Upfront costs for DfD are typically higher, creating tension with cost-efficiency goals—particularly in industries operating with tight profit margins. 𝐂𝐨𝐧𝐬𝐮𝐦𝐞𝐫 𝐁𝐞𝐡𝐚𝐯𝐢𝐨𝐫 Even when products are designed with disassembly in mind, they may still end up in landfills due to insufficient recycling infrastructure or consumer awareness. 𝐋𝐨𝐰 𝐏𝐥𝐚𝐬𝐭𝐢𝐜 𝐕𝐚𝐥𝐮𝐞 𝐚𝐭 𝐄𝐧𝐝-𝐨𝐟-𝐋𝐢𝐟𝐞 One of the biggest barriers is the low economic value of plastics at the end of their lifecycle. If materials hold no significant value for the owner, there is little financial incentive to prioritize disassembly for material recovery over cheaper, less sustainable disposal methods. To make DfD truly effective, alignment is needed between design, production, and the systems handling end-of-life processes. Until then, the gap between intention and reality may continue to persist—like oil and water. 𝘏𝘰𝘸 𝘤𝘢𝘯 𝘸𝘦 𝘣𝘳𝘪𝘥𝘨𝘦 𝘵𝘩𝘦 𝘨𝘢𝘱 𝘣𝘦𝘵𝘸𝘦𝘦𝘯 𝘴𝘶𝘴𝘵𝘢𝘪𝘯𝘢𝘣𝘭𝘦 𝘪𝘯𝘵𝘦𝘯𝘵𝘪𝘰𝘯𝘴 𝘢𝘯𝘥 𝘳𝘦𝘢𝘭-𝘸𝘰𝘳𝘭𝘥 𝘤𝘰𝘯𝘴𝘵𝘳𝘢𝘪𝘯𝘵𝘴?

The sintering plate substrate is made of special polymer composite materials, which are mixed by screening compatibility. Made from an advanced sintering process, the molded substation has irregular and fully-connected micron micro-holes. These micro-holes allow only clean gas to pass through, and microparticle dust is intercepted on its surface for dust filtration. In addition, the surface of the sintering plate becomes denser, smoother, and more accurate filtration through advanced sintering processes. At the same time, effectively prevent the work of dust sticky, and the use of gas pulse technology for automatic ash removal The pressure loss remains stable. High Filtration Accuracy: The emission concentration is much less than 1mg/Nm3 One-piece molding design: Using advanced sintering technology to create an extraordinary one-in-one finished product (no bonding). Excellent Mechanical Performance: High rigidity and high toughness filter material which can be extreme wear resistance. Will extend service life and be used wildly without restriction. Environmental filter: No addition of PTFE coating – no need to worry about the coating will fall off and reduced filtration efficiency. No PTFE cause environmental pollution. No resin added – no need to worry about the bonding area will fall off causing a shorter service life. Pure polymer composite filter material without any additions, so that the material can be recycled. As a sustainable material to achieve environmental protection.

Researchers at the University of Washington have developed a groundbreaking solution to the growing problem of e-waste by creating easily recyclable dissolving circuit boards. These new boards use a type of plastic known as vitrimer, which, unlike traditional materials, can be recycled repeatedly without losing performance or quality. This technology allows for the separation and reuse of components, significantly reducing environmental pollution from e-waste. The process involves heating the vitrimer to soften it, enabling the separation of materials that can be used to manufacture new circuit boards. This method not only aligns with environmental sustainability efforts but also promises cost-effectiveness due to its compatibility with existing manufacturing processes and the use of widely available chemicals.
