Abstract:
Pay as you throw (PAYT) is a usage-pricing model for disposing of municipal solid waste. Users are charged a rate based on how much waste they present for collection to the municipality or local authority. Waste is measured by weight or size while units are identified using different types of bags, tags, containers or even RFID. Services for waste diversion, like recycling and composting, are often provided free of charge where pay-as-you-throw systems are implemented. The system is based by a waste collection door by door (kerbside) with 5 streams (food waste, plastic packaging and metals, glass, paper and cardboard and unsorted waste). The results after the introduction of the combined system (door by door collection and PAYT) are almost immediate (3/4 weeks from the start of the system). The secret of the system is the "Invisible Hand" effect generated by the combination of the available volume reduction for the undifferentiated fraction conferring and the creation of a personal saving potential of each individual user.
