In India, 'extended producer responsibility' was introduced as an important feature in which of the following?

1. 'Extended Producer Responsibility' (EPR) is an environmental policy approach where a producer's responsibility for a product is extended to the post-consumer stage of its life cycle (i.e., collection, recycling, or final disposal). 2. In India, the concept of EPR was formally and significantly introduced as a mandatory requirement for producers of electrical and electronic equipment through The e-Waste (Management and Handling) Rules, 2011. 3. These rules mandated producers to set up collection systems and meet targets for the collection and channelization of e-waste to registered dismantlers or recyclers. 4. While the concept might have been discussed earlier or applied in limited ways (e.g., related to plastics), its formal introduction as a key, mandatory feature for a specific waste stream happened with the e-Waste Rules, 2011. 5. The Bio-medical Waste Rules, 1998 focused on segregation, treatment, and disposal by healthcare facilities. 6. The Recycled Plastic Rules, 1999 focused on regulating the manufacturing and usage of recycled plastics. 7. The Food Safety Regulations, 2011 deal with food safety standards, not waste management EPR.
