All around the world, population grows exponentially. This over populations may create several serious problems to humanity in the next years. Peoples waste is one of them, each year tons and tons of trash end up in landfills. This may create not only environmental but also space problems and health problems. This is especially serious in high density cities like Hong Kong were this problem has grown and needs immediate actions.
Problem. -
A) Municipal Waste. -
One of the direct problems created by over population is municipal waste, since each people inevitably creates trash each day. Municipal waste is principally composed by common household items. Yao (2010) shows that municipal waste is a problem in Hong Kong by mentioning …show more content…

Construction had always a negative effect on the environment especially in Hong Kong were the demand has increased the past years (Lu and Tam, 2013). The authors also mention that researchers have shown the negative effects in Hong Kong are land deterioration, resource depletion, waste generation, and pollution.
C) E Waste. -
Lopez, Bon, Ge, Shu, Oi, Yao and Hung talk about land in Hong Kong that were used for agricultural purposes and that now are e waste landfills. Some examples of soil were taken from there and all of them showed a high level in pollution in a relative short time. The authors also demand that regulations should be made because of the potential danger that this can cause in the future.
Solutions. -
Any solution its only possible if the community collaborates in recycling. A good way to make people involved in it is by teaching them when they are …show more content…
That way construction companies were forced to think in new ways to build, reducing their waste production. Yungpeng reports that this method reduced japans construction waste by 70%. He also mentions that changing the construction designs could also lower the waste production, he mentions that they tracked eight constructions and noticed that 43% of it could be improved to reduce waste production.
D)
Simonnot and Zhang (2012) report that E waste is a new form of waste that is growing in the same rate as technology grows. They also mention that because of the complexity of their components it’s difficult to recycle them and that there is not current efficient method to recycle this waste. The authors state that to recycle this kind of waste currently is by separating the components carefully. This method is slow compared to the rate of e waste produced each day. They mention two ways of reducing the contamination by e waste; those are immobilization and separation/concentration method. This method is not actually reducing the quantity of e waste but it reduces the quantity of damage they do to the environment.
Conclusion.
