Only 60% of local authorities in England and Wales took part in the campaign to promote waste awareness and encourage recycling.
Andrew Hartley of British Glass, one of the associations behind the campaign, said: We need more local authorities to be involved. The bigger the scale, the better impact.
Hartley confirmed project organisers would work more closely with local authorities next year to agree an appropriate time of year for the week of focused activities to take place.
Waste and Resources Action Programme (WRAP) chief executive Jennie Price said next years campaign should aim for improved recycling rates, rather than simply measuring success on media coverage, as had been the case this year.
