Can we take back the adapter and lighting cable?

We have some project in which we use apple product on our work but the accesories like apple adapter and lighting cable(1mtr) is not usable for us. Need to know if apple team can take it back beacuse it is useless for us and we do not wanna waste those all items. Please advise if have any other way to find out the way. Thank you
