Comparing the costs and benefits of virgin and urban mining

27/05/2021 In terms of the cost-benefit performance of urban mining, copper greatly differs from aluminum: copper is much easier to recycle from e-waste than from ELVs and WWC, whereas aluminum recycling should prioritize ELVs. The benefit-cost ratio can inform future operation decisions from initial design to scaling up in the circular economy industry. Economic incentive or cost decrease will be
