The bio degradable bags is a perfect way to make the composting process even easier. You can use them as ordinary trash bags and ones you fill them up you simply put them in the composter and turn the tumbler. Here is a tip If you add the wood-pellets in the bio degradable trash bag before you add the kitchen waste, you don't have to add them at the tumbler. This is another way that make composting easier and a part of your everyday life. 

The problem is that there has been a slight misunderstanding on how you start the process when composting with bio degradable trash bags. When you start composting with the bags you need to empty the waste in the bags, you can't just throw the entire bag in the composter. The reason for this is that you need to create the opportunity for microorganisms to start breaking down material, therefor you need to empty the bag in the composter and let the kitchen waste create a mixture, (you can throw the bag without the waste in the composter to, it will break down). Once the heat is created you can trow in the entire bag without emptying it.
