Plans to increase the amount of waste recycled or converted into energy have moved ahead with major contracts being awarded by Wiltshire County Council.
Two waste management contracts worth £300m over 25 years were granted to Hills Group.
A treatment plant is to be built in Westbury to convert 30,000 tonnes of refuse into renewable energy by 2008.
A further 50,000 tonnes would be moved from the Salisbury district to an energy plant being built near Slough.
Negotiations and tenders for this landfill diversion project have lasted more than a year.
'No choice'
The county council's Cabinet has given the green light to tenders from the Marlborough-based Hills Group, provided agreement can be reached on outstanding details.
More than 30% of Wiltshire household waste is recycled, with the remainder buried in landfill at Compton Bassett near Calne.
Toby Sturgis, Wiltshire County Council cabinet member for planning and waste said: "Moving away from landfill is something we all have to do. There are no longer any choices."
Wiltshire is one of a number of local authorities that will benefit from the energy generated by the Colnbrook plant, which is expected to put out some 31.6 megawatts of power for the national grid - enough to serve 32,000 households.
