If we look around, we can see electronic equipment in use today that was manufactured more than 20 years ago. For example, we are using a 20 year old TV in our house, as well as a 15 year old printer and I personally am using a 15 year old phone as my second spare phone.
The case for re-using is two-fold. The obvious result is to cut down on e-waste.
According to a recent UN report, the US produces about 6.3 million tons or 14% of the world’s electronic waste. Worldwide, almost 45 million tons of electronics were tossed out in 2016. Out of that staggering amount of electronic waste, only 20% has been recycled in some shape or form. The remaining 80% made its way to a more environmentally damaging end at the landfill.

At the heart of the issue is a technology sector whose profits are driven by planned obsolescence. Until the industry finds a way to thrive without needlessly pumping out new electronics at the rate that it currently does — all the eco-design processes, recycling programs, and Liam-like innovations will remain symbolic at best, and sleight of hand, at worst.

The second reason is that an electronic product is the result of a lot of effort, both physical and intellectual. It represents not only material resources but also the lives of people, which will be waste along with the product, if is is simply thrown away.
A great example of restoring electronic components that have been thrown out : an amplifier restoration.
