Some typos in the original paper are corrected. Some absurd parts are reconstructed to make an easy understanding. The method of TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) is detailed explained. After all, deep thoughts into the original paper are made. Keywords: E-waste, TOPSIS, Fuzzy multi-attribute, Group decision making Introduction E-waste is a kind of solid waste that contains various of heavy metal elements and could cause serious pollution to soil and drinking water. (M. Oguchi, S. Murakami, H. Sakanakura, et al, 2011) As life cycle of electro-products tends to be shorter and shorter, the amount of e-waste on the contrary is growing faster and faster. Such pollution will do great harm to human health and environment. However, in some countries, landfill is still used as a main method to dispose solid waste, which would lead to the contamination of soil and underground water. (E. Remon, et al, 2005) What’s
