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
