Rubbish Bin Classification

In the past, most counties and regions only use a kind of bin to collect all the waste. Because of it, the method to dispose the waste is to put all into landfill. But there are many poisons and polluted rubbish will contaminate the soil. As a result, it will be a serious environment problem which may even impact on human health. In addition, many materials and useful things cannot be recycled by this system. It is not sustainable and wastes a lot of resources. As the concern about this problem, many cities build a rubbish bin classification system to guide residents to put different kinds of waste into specific bins. It is a great way to collect rubbish, because the waste treatment plant can choose suitable method or technology to dispose different kinds of waste. In his blog, it will focus on the benefits of using rubbish bin classification system. Moreover, it also will show that how this system works.

 There are many advantages of using rubbish bin classification system. Firstly, it can reduce the occupied area of landfill. According to the information from Residential Waste and Recycling Guidelines in 2010, it can save about 50% land use in landfill because there are many kinds of waste are reused or recycled. Secondly, the classification of rubbish bin can reduce the impact on environment. For instance, battery contains many kinds of heavy metals and poisons. If throw it away or put it with other wastes, it will damage the environment including soil and water ecosystem. In addition, the plastic also have a huge impact on the environment if it is not classified well. Finally, the classification of rubbish bin system also can generate substantial profit because many wastes can be recycled or reused. For example, the waste plastic occupies about 4-7% in total waste. These plastic can be recycled to produce diesel----------about 600 kg diesel per 1 ton plastic. Furthermore, to recycle 1500 ton waste paper equals to save 1200 ton wood to produce new paper. There about 30%-40% of total waste can be recycled. Thus, to collect different kinds of waste in different rubbish is important for whole society.

After talking about the benefits of classification of rubbish bins, it will illustrate how this system works. Because I am living in Sydney, so that I will show this system in Sydney as an example. There are three kinds of rubbish bins used in Sydney. The table below shows the different colors and its waste category.

Table 1

The rubbish bins in Sydney are divided into three parts. The blue lid bin is for garbage/ general waste. The yellow lid bin is for recycling waste. And the lime green or plain lid bin is for organics. Furthermore, the size of each bin is different.

Figure 2

The picture above shows the different sizes of different bins. The size range of rubbish bin is from 80 liter to 660 liter. Each size has its specific use for different dwellings. After residents put the waste into right bins, the waste collection vehicle will collect these rubbishes and then deliver to different waste treatment plant or landfill. This system works well in Sydney and makes the environment in a great level.

To sum up, the classification of rubbish bin system is a helpful system which can reduce pollution and save resources. It is not only benefit the environment, but also good for residents. It is recommended that the government should encourage and guide people to throw waste into right rubbish bins. In addition, the counties or regions which still haven’t built this system should make it quicker.
