Lisbon

Lisbon, a high-density city with 552 700 inhabitants and 100 km2, is the center of a Metropolitan region with 2.8 million inhabitants and 334.000 companies, 97.000 of which located in Lisbon city.

The municipality has always been directly responsible for waste collection services, which are carried out with their own human and equipment resources. The Lisbon municipality is also responsible for the separate collection the recyclables (paper, packaging, glass, biowaste).

At this municipality a PAYT tariff targeting large waste producers (> 1100 L/day, 300 producers) will be implemented by the project LIFE PAYT. The list comprises hospitals, shopping centers, companies and other services.

The project will change the current waste collection system. Container identification, retrofitting waste collection vehicles and redesign of collection routes are some of the activities which will be carried out.  Damaged and very old bins (>20 years) will be replaced by new bins and the number of containers for separate collection will be increased.

The target is to identify with RFID chips 6000 containers in Lisbon. Each chip will have information about the owner and volume. When the bin is dumped into the truck, the data will be read by an optical sensor in the collection vehicle, and the data is sent via GPRS to a central platform, for processing. The volume of waste deposited by each producer into the collection system will be included in the bill sent every month to the owner of the container.

The bins’ identification and traceability through RFID systems and tags are essential to control waste generation and optimise collection.

A reduction of residual waste from commercial producers by 40 to 60%  is expected to occur in comparison with the current baseline of 35 100 tonnes/year in Lisbon. In addition, the dry fractions (paper, packaging and glass) are expected to increase to 10 300 tonnes of recovered recycled materials, leading to increased resource efficiency from waste.
