Background of the Government Policy in Hong Kong
In the year of 1983 to 1993, due to the increase in population, the demand of the food and drinks was raised, so the quantity of Hong Kong solid waste is doubled. Paper, un-recyclable plastic and glass bottle and aluminum were the packaging of the food and drinks which started to be a serious waste disposal problem to Hong Kong.

The increasing trend never stops. The amount of municipal solid waste generated each year in Hong Kong is enormous, given that the city houses almost 7 million people and is a regional centre of commerce. According to the statistic of the HKSAR government in 2000, Hong Kong people generates 17,910 tones of solid wastes every day, which is around 6.4 million tons of waste a year [1]. The solid waste were mainly from household, industrial and commercial, agriculture, and construction site. [2]

Although the HK government had prepared some facilities and plans, but she could not solve or minimize the negative influences of solve waste in a efficient way. Is there any loophole in facilities and plans, or any other way to over all the obstacles and have our HK clean in the future? I will discuss in the following.

Government Policy from past till now
In Hong Kong, Landfill was introduced which was a site for the disposal of solid waste by burial and had been the most common methods of organized waste disposal in the world.

In 1973, solid waste were deposed by landfill in area Shuen Wan which was in the rural area of Tai Po , other rural areas were used in landfill afterwards since the solid waste was produced continuously.

However, the population during the industrialization period in Hong Kong increased, Hong Kong colonial government found that landfill would not effectively solve the problem of solid waste, and also landfill was a conflict of land use with her high land price policy. Therefore, she introduced another method, incineration, to minimize the influence of the solid waste.

In densely populated areas like Hong Kong, large space for landfills was becoming increasingly difficult. Incinerator was used as a assisted means in the Nineteen Seventies and became an majority means to overcome solid waste problems in the Nineteen Eighties. There were 4 main incinerator sites, Kennedy Town Incinerator, Lai Chi Kok Incinerator, Mui Wo Incinerator, and Kwai Chung incinerator, which were located at the low populated areas.

Incineration is a waste treatment process that involves the combustion of organic substances contained in waste materials [3], which harmful gases and particles were formed, but people generally accepted this method, it is because the volume and mass were greatly reduced by incinerating. Secondly, the health effects of dioxin and furan emission have been lessened in emission control designs and regulated by government. Also, many cases in Europe showed the fine particles produced could be efficiently removed from the air by filters. It seemed incineration was safe to the human. Thirdly, incineration plants could generate heat and electricity, which was very cheap by turning waste to energy comparing with using coal or oil as fuel.

In 1986, Government had set up the Environmental Protection Department (EPD), it was responsible for co-ordination and implementation of pollution prevention and pollution control activities. Its set up the Air Pollution Control Ordinance which increase people awareness of air pollution. The ordinance emphasize air pollution was a great concern to Hong Kong people health and environment. To tackle this challenging and imperative task on cleaning the air, the Environmental Protection Department (EPD) has been enforcing the Air Pollution Control Ordinance and its subsidiary regulations. In 1989, the Hong Kong Government issued a White Paper, Pollution in...
