There are two kinds of bags to filter kitchen garbage for disposal. One is made of plastic which is Polyethylene and the other is made of Japanese paper. These filter bags have "EcoMark" indicating environmental protection. Kitchen garbage and paper bags are classified as combustible waste, and plastic bags are classified as incombustible waste. However, when a plastic filter bag is full of garbage, both the garbage and plastic filter bag have to be thrown away as combustible waste. We asked elementary school pupils whether a plastic and a paper filter bag are both combustible waste. Most pupils' answeres showed that a plastic filter bag was classified as incombustible waste, and a paper filter bag was classified as combutstible waste. Their reasons were as follows : When a plastic bag in burned, poisonous gas is yielded, but when a paper bag is burned, poisonous gas is not yielded. On the other hand, some pupils' answers showed that a plastic bag was classified as combustible waste. Their reason was that an "EcoMark" was printed on the bag.
