Waste disposal scheme: Zero Waste vs Land Filling

There are many waste disposal schemes and each has its own advantages and disadvantages over one and other. Here, we will be comparing zero waste and land filling. Land filling is a cheap method to dispose waste; it is also a very simple process as it just requires setting some land aside for the waste. On the other hand, it requires lots of space and overtime, it will corrode the land with harmful substances. Compared to land filling, zero waste is a more tedious method. Zero waste requires a large cooperation between the people, government, and company. And it requires a long time before a result is obtained. However, it is environmentally friendlier and less space consuming. Furthermore, zero waste creates new business opportunity. These are some comparison and contrast between zero waste and land filling.
In the context of Singapore, one needs to look at the characteristic of the land to determine which disposal scheme is suitable. Singapore is a small country so zero waste will be a better choice since it is less space consuming than land filling. Also, zero waste helps solve waste disposal problem permanenttly rather than pushing aside the problem like land filling. Next, Singapore is located at the equator. The temperature and weather makes her a good location to breed pest and vectors-mainly bacteria and diseases carrying organism like mosquito and animals. Land filling will provide an even ideal location for this organism. Also, the waste may undergo chemical reaction, to produce harmful substances to the atmosphere or to the land. Hence, the land becomes unsuitable for development without any treatment being done. Lastly, with Singapore’s efficient government and knowledge based economy, zero waste schemes can function easily to give a quick and good result. Henceforth, the most suitable disposal scheme for Singapore is zero waste schemes.

Yes, I agree with you that zero waste favours Singapore due to the limitaion of land.

Your work has reflected all the advantages and disadvantages of zero waste however, a clear comparison must be made between the two waste disposal schemes.
