Keep it clean
Small amounts of food don't interfere with the recycling but having a messy bin does make the job much less pleasant. Clean out jars and cans before putting them in the recycling bin as this will help reduce any odour.
Not sure where your aluminium goes from your glass? Don't waste time separating your recycling because you throw it all in the same bin. It's simple to get several smaller bins and use a colour code to easily identify the right bin to put each item in: green for food waste, blue for glass, etc.
