Users of the service are paying for collection and a clean environment and accumulation of waste in the nonpaying neighbour's yard impacts the users who regularly pay for the service. For example, street sweeping and safe disposal are public goods, since consumption of the clean environment cannot be restricted, the consumption of door-to-door collection is individual but the use is again common, so this is mainly a public good, the extraction, trading and processing of recyclables are examples of private goods. So in the case of waste management, the boundaries between public goods and private goods are blurred.
