It depends what country you are in. In the UK a retailer must accept electronic items for recycling (or provide you with the details of a free recycling service) The local council will have a recycling service (in most areas small appliances can be left out with your recycling bin). For items which might have a value there are companies that will buy them from you for a small amount and then recycle.
Please do not take them to a charity shop without checking beforehand as many cannot afford the testing needed before they can resell.
Photons are massless and along with other massless particles are known as Luxons because they always travel at the speed of light. But notice that the speed of light varies depending on the medium that light is crossing. (Eg 300,000 m/s in a vacuum . 200,000 m/s in glass)
So you could certainly transmit data faster than light through glass by simply transmitting it in a vacuum. But there’s little practical use except perhaps gravity wave detectors.
There are a class of particles that always travel slower than light (unless you accelerate them with infinite energy) and also a theoretical and controversial class of particles that travel at infinite speed and would require infinite energy to slow them to light speed. (If they did exist no means has ever been postulated to detect them)
