Taking your e-waste to the council tip doesn't allways mean it will be recycled in a lawful manner!
Most UK council tips are actually contracted out and the contractor has to sell anything anyone will buy to pay for disposal of the WEEE waste and the home & garden waste in the compacter skips.
Budgets are unsurprisingly rather tight and WEEE disposal invariably ends up with the lowest bidder - who most likely exports it to W. Africa.
There is a way you can at least delay your unwanted items entry into the scrap system; you can get rid of almost anything on freegle or freecycle, although its good form to indicate if an item is not working such as needs att'n or spares or repair.
If you want to sell the item there's allways Swapshop.
