International Seminar on Waste Management

PAYT Systems - Pay for what you throw away, Selective Collection and European Best Practices

12 December 2019

SANJOTEC - Science and Technology Park

São João da Madeira

On December 12, the first edition of this seminar dedicated to tariff systems applied to waste - type PAYT.

Designed in USA, back in the 1970's, Pay-As-You-Throw (PAYT) is a tool that aims at reducing the amount of waste generated and to improve selective collection. The system follows the polluter pays principle. The more an individual produces more waste and recycles less, the more he is charged. On the other hand, the less an individual contributes to waste accumulation, the less he is charged.


Although it is not rocket science, implementing a PAYT in Portugal is still a process seen as complex for mayors and technicians. In this seminar, it is the organizer's intent to showcase simple and useful tariff solutions. The italian example is one among many others.
