A variety of reasons impedes the urban household from sorting out plastics, temporarily storing them around the house and then transporting it down to the recycling bin - to the extent where they prefer to just dump it in the trash. Small plastics (like sachets, bottle caps etc.) are especially vulnerable to such behavior. To enable a circular design, it would be important to consider how urban households - currently a major contributor to the problem in this consumption economy, could be incentivized to recycle small plastics. An uber-like model, where an app could be used to book a free service to come by and pick up these small plastics, will help in clearing out a larger amount of small plastics from homes. Additional incentives to the household could be in the form of energy/trash credits or amazon prime award points. I have seen this implemented in an elementary form (before smartphones) in urban India with good success - especially with milk bags, shampoo sachets, and soap bottles.
