Waste4Change Supports Community Empowerment to Reduce Waste The garbage bags are valued differently according to the volume of garbage that can be accommodated, so as to ensure that citizens understand that there are costs to be paid to be able to recycle and ensure the waste they produce does not pollute the environment. This is one of the reasons why the South Korean government requires its citizens to buy special garbage bags to deposit waste. This is because residual waste management and some types of waste recycling process require no small cost, it could also require expensive technology. However, spreading the awareness that waste is valuable and can be exchanged for money should also be accompanied by a condition that the first step of the 3R, namely Reduce, should be prioritized above all else.
