Although some collections may occur on the same day for example black bags and glass bottles and jars, they are collected at different times between 6am and 2pm.
Er y gall rhai casgliadau ddigwydd ar yr un diwrnod, er enghraifft bagiau du a photeli a jariau gwydr, maent yn cael eu casglu ar wahanol adegau rhwng 6am a 2pm.
