The "CENTS4PACK" project has been awarded to Candam Technologies and Valoriza Medioambiente within the framework of the LIFE 2022 European call for the environment "Circular Economy".
It consists in the implementation of a "Reward as you throw" system in which the citizens are rewarded for recycling correctly. The project is focused on plastic packaging, bricks, cans and glass. With the project also the local economy is promoted, as it provides a platform for local businesses advertising.
The innovation of the project consists in the use of a device designed by Candam, which is capable of distinguishing from the sound made when the waste falls, its typology among the classes mentioned above. In this way you can know if the user recycles correctly, preventing optical recognition systems, which are not simple and fast for daily use and also break down easily when they are located outdoors.

With the implementation of the project, the city of Guadalajara aims to improve the collection ratios of these waste types (setting the base objective at 15%), thus aligning with European waste management policies, as well as digitizing the waste cycle.
The project will install 500 units of the devices distributed in glass containers and containers and it is expected to involve a population of 43,000 inhabitants and more than 200 businesses.
The project has started in September of this year and its completion date is scheduled for February 2025.
The effectiveness of the system increasing the collection ratios will be analyzed, analyzing the current situation and measuring the impact of the implementation. 
The project deliverables will be updated as they are generated and uploaded to the European Union platform, being able to download them in the documentation section available on this page.
