A drop box for old phones, chargers and batteries

In the port city, broken phones, chargers and batteries are thrown out with ordinary rubbish. They leak harmful material into soil and water. Place a sturdy lidded box at a neighbourhood grocery or school gate, with a clear label of what may go in. Once a month a volunteer empties it and takes the contents to a repair shop or a collector who handles such items. Note too that batteries are never to be burnt or broken open. You need one box, the shopkeeper's consent, and one regular volunteer.
