     English families face being limited to 80 bags of rubbish a year. Households throwing away

more waste will have to take it to the tip (垃圾站) or buy a limited number of extra bags.

     Doretta Cocks, protester of the Campaign for Weekly Waste Collections, said, "They must

think we are fools. How can they claim to be concerned for the environment when they tell people

to drive to the local tip? And what do you do if you don't have a car? Walk?"

     The plan ignores the voice from ministers to end such heavy-handedness (笨拙).

     It is to be carried out by the Tory-led council (市政厅) in Wokingham, Berkshire, and is

already in operation in Brozbourne in Hertfordshire.

     Many of the 180 councils that still offer unlimited weekly rubbish collections are watching the

trial.

    Wokingham officials have told residents that 75-litre bags will be given to each household and

anything not left in them will not be collected.

    "Every household will receive 80 bags every year," it said. "You can buy extra bags in rolls of

ten but this will not be encouraged."

    Families of five will get 100 rubbish bags a year and households of six or more will get 120.

    Residents will have a weekly recycling collection limited to cans, paper and cards, plastic bottles

and so on.

    Plastic packaging and glass including bottles must either go with the general waste or be taken to

recycling points. Green waste pick-ups cost an extra £60 a year.

    The council has told residents it will save £922,000 a year under the new system. There will be

no local consultation (商讨) before it is introduced next April.
