     In today's throw-away society, dealing with the city's growing mountain of waste is an increasing

challenge for the city council (市议会).

     Recently, Edinburgh is faced with the problem of disposing of (处理) about 250,000 million tons of

waste a year. Despite different ways to dispose of much of it in a green manner - largely through

encouraging recycling-its aging facilities such as the Powderhall landfill do not have the ability to deal

with it.

     The European Union (EU) has issued a new policy, regulating how such mountains of waste are to be

disposed of. The five councils ( Edinburgh, East Lothian, West Lothian, Midlothian and Borders ) face

fines around £18 million a year from 2013 if they don't increase recycling levels and rely less on landfill. With this in mind, the councils got together with the idea of building a large incinerator plant (垃圾焚烧

厂) to burn half of the waste produced in their districts. But this plan fell apart after the change of target

levels by a new UK government waste policy which required that no more than 25% of the city's waste

should be disposed of in this way by 2025.

     After the plan was abandoned, a private company which already transported millions of tons of the

city's waste by train to a landfill site near Dunbar, offered an alternative solution when it suggested

opening a huge waste site near Portobello.

Since Powderhall is supposed to close in 2015, it seemed necessary for the members of the Edinburgh

Council to accept the suggestion. But soon they turned it down - after 700 local objections reached

them - because it would have meant hundreds of lorries a day making loud noise through heavily

populated areas.

     That still leaves the council with a problem. By 2013, only 50% of 1995 levels of waste will be

allowed to be sent to landfill. Even if recycling targets are met, there will still be a large amount of

rubbish to be burnt up. Due to this, Edinburgh and Midlothian councils have now decided to work

together to build an incinerator plant as time to find a solution is fast running out.
