WasteApp data

This dataset was produced under URBAN-WASTES's WP5, which collected data to analyse the waste behaviour of the people using WasteApp. It did not collect any personal data but only statistical data. No e-mails, phone numbers or actual names were stored in the database. The users could use this aforementioned information as username, but the actual data stored in the database was a hashed version. Hashing is an injective transformation that cannot be reversed. Hence, if a hashed version of a full name were known, the actual input name could not be obtained.

The WasteApp databases comprise the following information:

City data. Each pilot city must input the following data in the database, regarding container information.

• Container ID
• GPS coordinates
• Type of container

Sponsor data. The information provided by sponsor companies, processed and stored by cities.

• Business ID
• Prize-collecting location GPS coordinates
• Offered awards

User data. Users were asked, after the installation of the App, to provide useful information to the project’s analysts. These data are the following:

• Gender
• Age range (segments to be defined)
• Type of visit (business, touristic, permanent or temporary resident)
• Date of the visit (automatically gathered)
• Duration of the visit (segments to be defined)
• Type of host (hotel, private house, collaborative hosting, other...)
• Nationality (from reduced list – European Union countries, USA, Canada, China, others)
• Education level (segments to be defined)
• Profession (segments to be defined)
• Technology usage level (automatically obtained by inference)

Each time a user throws waste into a container; the App must store the following information:

• Container ID (this ID directly refers to the information stored in the Containers Table, which is location and type of waste)
• Timestamp

Furthermore, the App asked the user to provide the following (if applicable):

• Container is in its predefined position?
• Hygienic conditions of the surroundings
• Is it in good state?
• Is it accessible?

Each time a user sorts waste, an amount of points would be earned. The users could then exchange these points for awards. The sponsors should provide the following information about the offered awards.

• Name of the award
• Amount of points
• Time of prize
• Sponsor ID

Each time a user retrieves a prize, the corresponding points would be extracted and an input in the dataset would be added, including the following information:

• Prize ID (this ID refers to the information introduced by the sponsor companies)
• Timestamp
• User ID
