This design aspect is a significant determinant to the effectiveness of product disposition options. Consistent with multiple recovery loop approach for minimizing volume of e-waste, usable constituents are inspected to reuse in new and/or used product assembly. If the types of joints, fasteners and connectors administered during product assembly were complex and difficult to separate, firms have to engage skilled labour to gather benefits from backward flowing products. Some assembly materials can only be separated by application of heat and force, such as welding, adhesives and mechanical joints (i.e. irreversible snap fits). These joints challenged extraction of valuables as either both conjoined parts are susceptible to damages during disassembly or only part with more value is reused by preserving its aesthetic value at the expense of the other part. Disassemblability of products influences both time-sensitive recovery (i.e. repair, recondition, remanufacture) and cost-efficient recovery (i.e. recycle). However, this design factor is insignificant to disposal activities as returns with limited recoverable value are best shredded and crushed for recovery of precious materials.
