Everything is very unrecyclable, because there are no laws forcing true recycling.

Designing something to be recyclable and also designing the equipment that could recycle it is much more expensive than designing it to be just dumped as garbage and designing only the equipment needed to make it from pure raw materials.

Using most materials in closed cycles (except those that can already be recycled efficiently by living beings), which is absolutely necessary for the survival of mankind, will never happen unless mandated by law, because any business tries to push such costs to someone else.

Recycling will happen only when the sales of any object will be forbidden, unless the raw materials from which it has been made, besides a list of exceptions, can be recovered in a very high proportion, e.g. 99% and someone will be liable if this does not happen.

Obviously, if such laws will ever be adopted, they would have to implemented very gradually, i.e. there should be a grace period of several years, and then the mandated efficiency of recycling should be initially very low, with a plan to raise every few years. Similarly, the number of exceptions might be initially large, but then some of the exceptions should be eliminated when adequate technologies are developed.

For now, there is no serious research in true recycling technologies, which really reverse the fabrication process of a product, because there are neither any money to be gained from having such technologies, nor any money to be lost from not having such technologies.

Electronics devices are harder to recycle completely than almost anything else, because besides materials that are used in great quantities, e.g. plastic, copper and silicon, there are a lot of chemical elements that are used in minute quantities, e.g. arsenic, antimony, germanium, hafnium, cobalt, tungsten and many others.

Those elements, even if they are much more valuable than the major elements from an electronic device, are also much more difficult to extract from a device, because of their very low proportion.
