1. What is waste ?
Wastes are objects and materials that the user no longer wants to use and dispose them, however, in some contexts, it may not be useful to this person but is the benefit of others. In life, waste is visualized as substances that are no longer used with the toxins emitted from them.
According to current statistics, the total volume of domestic solid waste in Vietnam is estimated around 12.8 million tons/year, in which 6.9 million tons/year is from the urban area (accounting for 54%), the rest focuses in districts, towns and communes. Forecast shows the total volume of urban domestic solid waste until 2020 will be about 22 million tons/year.
