To have easily recyclable products, it should not cost much and not require too many manual operations when recycling. In other words, easily recyclable products must consider how they will be recycled at the end of their service life from the very first stage of designing.
For example, more than twice as many screws and parts were used for older model TVs than for recent models. The more complicated the assembled product, and the more parts used in it, the more time it takes to dismantle it. Also, it takes lots of time to sort materials because there are so many kinds of materials used.
Comparing CRT TVs that were produced in 1983 to those produced in 2003, the ones produced in 2003 have fewer parts and kinds of materials. Moreover, they are sturdy and long-lasting. Also, they are designed to be more rapidly and precisely recycled than the older models.
The same is true for plasma TVs and LCD TVs. Compared with the earliest models, new models can be dismantled much more quickly.
