EMTRE is an application designed for the residents of the València metropolitan area who wish to utilize the network of fixed and mobile waste collection points. Users can identify themselves at various collection points and track their personal history of waste deliveries. Recycling at these points can lead to discounts on the waste treatment fee included in the water bill. The app also provides information on the nearest fixed and mobile collection points through geolocation, along with their opening hours.

Additionally, EMTRE includes a database to assist users in correctly recycling different types of waste and promises further features in future updates. To access the benefits related to waste treatment fees, users need to authenticate with their national ID and water supply company contract number.
