Reuse, Reduce, Recycle
The best thing to do with old recyclable things you have lying about is to first try to reuse them. If you can't reuse them then recycle it. The most important thing to remember is to reduce your trash. Another good thing to do to save electricity is to shut off the lights when you don't need them, don't leave chargers plugged in when something is done charging, and don't use unnecessary electric objects. A good way to save water is don't leave the water on when you are brushing your teeth, and take shorter showers.
