A review of methods to trace material flows into final products in
Rationale for the End-Use Transfer (EUT) method variation, applied to an exemplary monetary input–output table (MIOT): during EUT, the direct flows of products that are intermediate demand in the logic of MIOTs, but end-use or final demand in dynamic material flow analysis are transferred from the inter-industry flow matrix Z to final demand ...

Because process waste is generated in the production phase, it should be classified as an output if the mass balance between inputs and outputs is to be established. The reduction in the purity of materials in the use phase is relevant for materials made of polymers, such as paper, textile, and plastics, whose chemical bindings loosen over time.
