Reverse vending machine:
In order to recycle house and street wast, Recycle bins are common things to use  in countries with recycling law. Although this is a good way to separate rubbish from recyclable materials, sometimes individuals do not bother themselves to separate all of the recyclable materials or just throw them in the street. Reverse vending machine is one of the ways which can alleviate this issue. According to World Intellectual Property Organization (2014) this is a device which accept recyclable materials that are used for beverages and return the cost of them to people. This organization also claims that reverse vending machine first was invented in Norway in 1970s because at that time supermarkets were responsible to get back empty bottles and return the cost of bottles to people. Therefore supermarkets became full of empty bottles. This machine was invented to make this problem easy for them. Today this machines are using in Norway and some other countries to encourage people to recycle and do not throw beverage containers in street. Other advantages of using this machine are to save more land fields and decrease the usage of more energy and material to produce beverage containers. In Norway 20% of annual carbon emission has been reduce by this action (WIPO 2014)
