15.11 Technology and Society
Information technology has impacted people’s lives and changed how they learn, think, and communicate. People’s
health has been hurt by the fact that they use technology too much, which makes them less active. IT makes people’s
lives better, but e-waste is bad for the environment and could be a big problem for the next generation. Further, IT has
given birth to cybercrimes, a new form of crime.
15.11.1 E-waste Management
Electronic products that are no longer needed, are broken, or have reached the end of their useful lives are called
“e-waste.” The e-waste includes smartphones, desktops, laptops, hard drives, cables, batteries, routers, switches, and
hubs which are no longer required. The poisonous substances that are released from the metals as a result of chemical
reactions in e-waste are harmful to our environment. E-waste management is a holistic approach to remove electronic
trash from the environment. It aims to reduce, reuse, and recycle electronic waste.
Proper Disposal of used Electronic Gadgets
The following methods can be used to dispose off the e-waste:
Landfills: This is the approach to e-waste disposal that is most frequently used. The e-waste is buried in deep dirt
trenches. But since e-waste contains dangerous materials such as lead, mercury, and other materials that leak into the
earth and destroy the soil and underground water, it is not considered a good practice to dispose off e-waste.
Incineration: The incineration process involves burning e-waste at high temperatures in incinerators. This reduces the
amount of trash, and the energy that is released can also be used. However, burning e-waste releases toxic chemicals
that are bad for the environment.
Acid Bath: In this method, the e-waste is soaked in solutions of sulphuric, hydrochloric, and nitric acids to get the
metal out. The salvaged metal is then used to make other things. However, acid solutions are difficult to dispose off.
Releasing acids into water is bad for living beings.
Mechanical recycling: The most effective and environmentally responsible method is to recycle. In this method, used
circuit boards, ICs, motherboards, and other parts are taken from e-waste and recycled by dry physical separation.
A printed circuit board (PCB) recycling machine may be used to separate precious metals like copper, lead, and other
metals from e-waste.
15.11.2 Societal Issues and Cultural Changes
Technology has had a great impact on our social and cultural environment. The technology revolution, especially
the Internet, has changed everything, from education to entertainment to health to how we celebrate holidays and
how we talk to our friends, family, and coworkers. While IT has opened up new entertainment options, excessive
online gaming and other forms of entertainment are bad for our health because they make us less active. IT has also
introduced new avenues for criminals in the form of cybercrimes.
