Did you know an estimated 442 million unused and unwanted cell phones were found to be lying in people’s home in 2015? According to a UN study, about 41.8 million tons of electronic waste was discarded worldwide in 2014, with only 10 – 14 percent of the total disposal done right. Most people don’t know that electronics contain valuable materials like copper, tin, iron, aluminum, fossil fuels, titanium, gold, and silver. Not just that, many items from e-waste such as plastics, metals, and gold can be recovered, reused and recycled. Here are 15 terms that everyone in the data eradication industry should know.  E-waste also contains many hazardous materials like cadmium, lead etc. so they should be properly recycled with a recycler like Surplus Service.


1) Degaussing Alkaline Batteries

Alkaline batteries are named so because they contain an alkaline electrolyte of potassium hydroxide. These batteries have higher energy and longer shelf-life than zinc batteries

2) Degaussing

The process of completely erasing data by reducing or eliminating an unwanted magnetic field (information) stored on tape and disk media

3) Data Wiping

Data wiping refers to the process of removing data from a read or write medium so that it can no longer be read

4) Data Shredding

Device Shredding refers to the process of using specialized equipment known as shredders or disk crushers which can break the surfaces, heads, and alignments of a data device. This makes the device unusable

5) Biodegradable Material

Refers to waste material which is capable of being broken down by microorganisms into simple, stable compounds such as carbon dioxide and water. Food wastes and paper are biodegradable

6) Database

A collection of data in a digital format which is structured and organized. This data is usually accessed via a database management system (DBMS)

7) Data centre

A large physical facility that stores a large number of servers and data storage devices. Data centers can belong to a single company or provide their services to many organizations

8) Data migration

Refers to the process of transferring data between various storage types or formats, or between different computer systems

9) Data mining

The process of deriving patterns or knowledge from large data sets

10) Downstream Separation

Refers to the separation of material after they have been shredded. These materials usually leave the shredder on a conveyor belt. Then, they are sent forward through magnets, eddy current separators, trommels, and other downstream separation equipment

11) Hazardous Waste

Refers to a solid, liquid, or gaseous substance which, because of its source or measurable characteristics, is classified under state or federal law as potentially dangerous and is subject to special handling, shipping, and disposal requirements

12) Fiber Separation

The method of breaking apart fibers, for example, crumb rubber processing environments. Shredded tires are processed into a granule then refined to a screening and separation process using air systems to remove fiber

13) Non-Shreddable

Refers to materials that will not shred in the shredder due to materials or hardness. In such cases, the shredder shuts down to allow the operator to remove substances from it

14) Data security

The practice of protecting data from destruction or unauthorized access

15) Data collectionData Eradication Industry

A process that captures any type of data
