In an imaginary town, Greendale, residents carelessly dispose of recyclable plastics due to minimal additional trash pickup fees, leading to recyclable plastic piling up in landfills.

The upward-sloping private marginal cost line shows residents' trash disposal costs, which increase slightly with the production of more plastic waste.

However, the social marginal cost rises faster as waste piles up. This is due to a higher negative externality associated with larger volumes of waste.

Recycling could reduce these externalities, but it comes with its own costs.

The marginal cost of recycling increases as more plastic is recycled.

To fix this, policies like disposal fees or recycling permits could help internalize the societal costs.

However, such policies are often challenging to imple
