User-pay domestic garbage collection systems require householders to pay for each bag of garbage requiring disposal. The benefit is that it encourages them to practice the 3Rs of waste management (recover, recycle and reintegration) which in turn minimizes their disposal costs. Their creativity and participation is engaged.
There are several ways of implementing a user-pay system, including: requiring residents to purchase special bags; requiring residents to purchase special tags to seal the bags; paying for each bag set out; paying for each bag set out over a specified number; restricting the number of bags placed on the kerb; renting a standardized container in which the garbage is placed; and weighing each bag and billing each household based on the monthly weight.
