Through this system, factory will be able to receive rubbish and produce profit, this action not only reduce people’s living cost but benefit the environment. As a international city, Sydney always concentrate on garbage recycle and use. The same thing also happened in San Francisco, USA. This essay will discuss the samilarity and differentia between recycling system in Sydney and San Francisco. Firstly, both of those citizens in Sydney and San Francisco all have same philosophy, which is rubbish must be classify and recycle. Since children became knowing the things theirs parents will told them they should bring rubbish into the bin. When children became older, theirs parents will teach them to classify the rubbish. For example, there is a children from Sydney called Frank, his family always receive some international student. Since they arrived those international students will be told they should classify rubbish. The same situation also happened in San Francisco. Children and teenagers always able to received garbage recycling education. Besides, the exorbitant fine also will reminding people keep the rules.

The giant bins will be hoisted to the surface by hydraulic lifts and emptied into garbage trucks as normal by City staff” (Lord Mayor Clover Moore 2013).1 The San Francisco recycling and garbage law effective as of late October 2009 requires every household and business to use three different bins for discards: blue for recyclables (e.g., cans, bottles, paper, yogurt containers); green for compostables (e.g., food scraps, leaves, dirty paper napkins); and black for trash (including plastic bags, Styrofoam and diapers). Many San Franciscans have been using the three-bin system for months or years, but now it is mandatory.2 So it is easy to draw a conclusion, both of those cities have advanced recycling system.
