Lifecycle Impact Mapping focuses on social and environmental impact rather than cost. It helps the user identify and assess impacts.
It may help to focus attention on the disposal phase before the procurement is carried out. This would allow you to build end-of-life management requirements into successful contract performance clauses and your own internal management procedures. For example the uplift and recycling of printer cartridges, reusing delivery pallets, etc.
Please note: Life cycle impact mapping can be used alongside life cycle costing as part of the procurement process.
