1 Introduction

With more computing devices (computers, mobiles) than people on Earth and powerful manufacturing companies whose business is manufacturing, the successful implementation of the 3Rs (Reduce, Reuse, and Recycle) for electronics, and the migration towards circular ICT goods and services involves diverse stakeholders and becomes vitally important for the environmental sustainability of our planet (ITU 2020). Providing a detailed and large dataset about the computing devices beyond the first usage is the aim of this report.

The dataset originates from eReuse.org1, a global community formed by social, public and private organizations interested in responsible reuse and recycling of computing devices (Franquesa et al. 2015; Franquesa and Navarro 2018). Since 2013 eReuse collects details about the second-hand computers and their components collected, refurbished or recycled, with the purpose of keeping track of these devices and be able to analyze that data over their full lifespan until final recycling.

Devices are handled and data is extracted by different entities using eReuse software tools. They can pool together part of their extracted data according to a data sharing license.

From that data pool, it is possible to deduct detailed life-cycle data for each device across its lifespan, from the initial registration of a device until the last recording in a recycling center before being destroyed. The traceability dataset of individual devices and components allows different analysis per device and groupings. Different actors, such as buyers, consumers and device owners disposing devices, can obtain useful statistics about the real durability of the equipment, showing for instance which manufacturers make more durable and repairable devices and components. As the dataset becomes more quantitatively robust, it may be of interest to consumer watchdog and reuse and repair platforms to help raise public awareness about durability, so buyers can choose the more environmentally sustainable electronic devices, increasing the reuse and recycling ratio at the end of the devices second and third lives.

The rest of the paper is structured as follows. The next section describes the dataset: the scope, collection, anonymisation and cleansing. Section 4 explores the potential of the dataset for durability analysis. Section 5 looks at other analysis, such as exploring duplicates and distribution of features.

2 Data source

The main material of this analysis is a dataset that contains the devices processed by resellers organizations federated to eReuse device data commons license. This report is the first attempt to know the value of the data we collect.

The dataset only contains technical data about the functional status of computing devices and components its contains. It does not report on whether the devices have been reused, their total time of reuse, whether their users have any kind of socio-economic vulnerability, the price paid for the devices, or whether and if devices are in the end recycled at authorized points.

2.1 Data scope

We have limited the study to only resellers with operations in Spain that has accepted the eReuse device data commons license. The total number of resellers are 20. Data has been collected between 2013-10-08 and 2019-06-03.

2.2 Data collection

The resellers uses the Workbench software tool (link) for hardware discovery, stress test and operating system installation. The device boots from an USB drive or PXE network server, runs unattended and only requires two minutes for the basic test. The result of the hardware scan and stress test is a json file per device that is extracted and stored elsewhere: in the resellers server’s disk, in a USB drive, or uploaded to their private inventory system (DeviceHub in our case).

2.3 Data anonimization and aggregation

Once the device information is stored in our device inventory system (DeviceHub), for participants (resellers) that accept the open data license, part of this data can be exported to this dataset, through the DeviceHub API of those resellers that accepted the license. The name of the inventory is automatically anonymized with a code that represent the source (the reseller).

The Devicehub API only offers anonymized data, excluding any business sensitive or personal details. There are two modes of anonymization, the more stringent includes the anonymization of the serial numbers of the devices.

2.4 Data content

The dataset contains one record (row) per computing device with a set of features or characteristics that contain metadata (such as type, model, manufacturer, version, date, serial, address, capacity) about each part/component detected.

The dataset is available from here under license CC BY 4.0.

2.5 Data sample

In this table sample we show the first 5 columns and rows of our data set. A row is a record/observation/trial, which corresponds to the statistical unit of the dataset. In our analysis each row or observation represents a device. In the table, a column is a variable/feature, for us are features of this devices, its components or information of its origin.

This is an example of a dataset:

Only technical data columns are exported and the serial numbers are anonymized. We have a total of 192 variable/feature.

2.6 Data selection

We will focus on studying only the significant features for studying durability. Descriptive statistical data for all features is shown in Annex2.

The variables we will study are: Source, Type, Subtype, Serial.Number, Registered.in, Model, Manufacturer, HardDrive.1.lifetime.hours, HardDrive.1.lifetime.years, RAM.GB, HDD.MB

2.6.1 Summary of significant features of the study

For our selected 11 features (columns) there are 8458 observations (rows) giving a 93038 total observations, there are only 3257 complete values and 11238 total of missing values.

You should immediately notice some surprises:

  1. 38.51% complete rows: This means only 38.51% of all rows are not completely missing!
  2. 12.08% missing values: Given the 38.51% complete rows, there are only 12.08% total missing values.

2.7 Data cleansing

Given an observation (a device), if it is missing the data of some of its features, for example, we do not have the model feature for it, we will say that we are missing a value for this observation. The values therefore are the cells of our table.

2.7.1 Data cleansing: Removing non interesting observations (rows)

From the above chart, HardDrive.1.lifetime.years and HardDrive.1.lifetime.hours is mostly missing with 5193 values. The reason because there are many missing values for HardDrive.lifetime is that we only have this value for devices of type “Computer”, so our table contains many nulls for ComputerMonitor, Peripheral and other types.

Let’s just select the “Computer” type filtering in that way non desired observations. We have reduced rows (devices) from 8458 to 5870 after removing rows diferent of type “Computer”.

Selecting only computers devices we have reduced missing values for feature HDD.MB from 426 to 27.

The value HardDrive.1.lifetime.hours still has 2605 empty values. The reason is that at the beginning the Workbench tool did not collect this information.

2.7.2 Data cleansing: homogenize manufacturer

Data cleansing or data cleaning is the process of detecting and correcting (or removing) corrupt or inaccurate records from a record set, table, or database and refers to identifying incomplete, incorrect, inaccurate or irrelevant parts of the data and then replacing, modifying, or deleting the dirty or coarse data [Wu, S. (2013)]. In this step we perform a data cleaning process on the name of the manufacturer. For example, there are devices where the name of the manufacturer appears as: “Hewlett-Packard” and as “HP”. In this process we will rewrite the name of the manufacturer so that it is unique, in the previous example, both devices will remain as “HP”.

There are 74 distinct values for manufacturer feature before data cleansing. For example: Apple, Hewlett-Packard, LENOVO, Gigabyte Technology Co., Ltd., ECS, ASUS. For example, In the case of Hewlett-Packard our data has these values: Hewlett-Packard, HP Inc., HP Pavilion 061, HP, HP-Pavilion. We can find the misspelled name or even the model’s name. This is an error in the information that the manufacturer stores in the firmware of the computers. For more transparency you will see later the substitutions that have been made. In the Hewlett-Packard example we are going to substitute the different occurrences with the string “Hp”.

We will then carry out this process for all the manufacturers of our data set. This code should be updated as new data enters the system. We will also remove symbols that may make searches more difficult. For example: “Gigabyte Technology Co., Ltd.” will be replaced by “Gigabyte Technology”

2.7.2.1 Data cleansing: homogenize product variants

Products models with variants are products that have similarities, they are based on the same model, but differ in some aspects from one another. They offer customers various purchase options for a product such as different colors, sizes, dimensions, flavors, etc. In our analysis the variants of the models do not provide us with useful information and reduce the number of observations we have. in this step we group the variants of a device model into one variant per model. For example: “HP Compaq 6005 Pro MT”, “HP Compaq 6005 Pro SFF”, “HP Compaq 6005 Pro SFF PC”, will be grouped in the model name “HP Compaq 6005 Pro”.

2.7.4 Data cleansing: removing non complete observations

From the above chart, HardDrive.1.lifetime.years and HardDrive.1.lifetime.hours is mostly missing with 5193 values. The reason is because in the begining of our research we do not retrive this information. We need to exclude from our dataset the rows that do not have the key values for our study.

Number of observations in our dataset before removing non interesting observations: 5870

Number of observations in our dataset after removing non interesting observations: 2797

3 Data analysis

3.1 Durability

Durability definitions:

  1. The period in which the manufacturer promises to replace or repair the product free of charge.
  2. Information about the average/expected or minimum lifespan of products before they defect or break

The information we have is the hours of use of the devices. This information allows us to estimate the second definition of durability. Some of the questions we will be able to answer are: 1) What is the estimated durability of my device?, 2) Which manufacturers have had more durable devices? (consumer), 3) If I repair this device, how many hours do I expect it to keep working?.

The durability tables generated in this report do not have enough data to be able to say that a manufacturer or a model has a concerete durability. We must continue to collect data and the scientific community must validate this proposal.

In future studies, we will address also the first version of durability. To estimate the first definition of durability we must have the time period in which the devices enter the market and are finally recycled. For the first date we would use the date of manufacture of the model, this information can be obtained from databases, and the second date we will obtain from the eReuse traceability system; as a date we will choose the moment in which 90% of the devices of a model are recorded as recycled.

4 Other analysis

4.1 Exploring duplicates values on unique expected features

Each part/component of the electronic hardware of a computing device, has an identifier (ID) and metadata about its characteristics can be retrieved by a software tool that runs on the device, obtaining hardware information (such as model, manufacturer, version, date, serial, address). This ID may be unique but common to all instances (clones) of a model, or specifically unique to an individual instance if each item contains unique serial numbers, addresses or equivalent. Each device, composed by multiple components, can get a unique ID that results from a combination of component IDs. A desirable property of these unique IDs, to assess circularity (reuse), is that they can be independently produced at any time from hardware analysis, so that an ID matching operation can determine the hardware component or device is the same. A match may be exact or plausible (a large partial match that corresponds to a device with most parts intact and a few replaced due to repair or upgrade, e.g. a computer with the same parts but different hard drive). That allows to detect matches and multiple appearances across independent device inspections and produce traceability and life-cycle information about individual devices by different actors in different moments of their cycle.

Devices move to different locations, and they are reused by different users and organisations. Because of this, devices are registered in different resellers. Synthetic identifiers, like internal database identifiers, cannot be used outside an organization as they cannot be regenerated if lost, and serial numbers are not always unique. Although they could work in a few cases, that defeats reliable global traceability. eReuse.org proposes a HID to track devices or components. It results from the concatenation of the manufacturer name, the model and serial number of a device, for example acer-aod270-lusga_0d0242201212c7614. A hash should be applied to these Ids to protect the privacy of the resellers. In the next report we will analyze to what extent this HID is unique in the system.
