Wipe off any food residue from the foil or tray with a sponge. You can dunk the tray in the washing up water - no need to run the tap. Then do the scrunch! Foil, tub and pot lids and wrappers together to form a ball - the bigger the ball, the easier it is to recycle.
Remember that even if you send it for recycling, using disposable foil and trays create waste. It isn't efficient and requires energy and transportation. Try to switch to reusable items like silicon covers, baking mats and beeswax sandwich wraps?
