This objective can be achieved through recycling and collection targets of the product or materials and through incentives for consumers to bring the used product back to the selling point. These include measures such as deposit-refund schemes, Advanced Disposal Fees (ADF), material taxes, and upstream combination tax/subsidy (UCTS) that incentivise the producer to comply with EPR. In South Korea for example, ADFs are imposed on importers and producers of products that are hazardous and more difficult to recycle. Standards can be mandatory or applied by industries themselves through voluntary programmes. Measures can include imposing information requirements on producers such as reporting requirements, labelling of products and components, communicating to consumers about producer responsibility and waste separation, and informing recyclers about the materials used in products. This underscores the most pressing need to address issues of efficient management of landfill sites and other waste collection processes.
