The Scottish government has set ambitious targets for household waste recycling
Dramatic improvements have been made in the amount of household waste recycled in Scotland over the past decade, a report has found.
But study by the Zero Waste campaign also said more needs to be done if government targets are to be met.
The study showed some 67% of newspapers and 60% of glass bottles were sent to recycling centres last year.
But only a fifth of plastic bottles and less than a quarter of cardboard were recycled.
The Scottish government has set a target of recycling or composting 70% of municipal waste by 2025.
It stated that before devolution, Scotland was entirely dependent on landfill disposal of waste.
However, almost 36% of municipal waste is now recycled, and the total amount of waste has been reduced from 10.6 million tonnes to 7.4 million tonnes.
Scotland has already achieved the 2009-10 target for reducing the amount of biodegradable municipal waste sent to landfill, the report said.
Iain Gulland, director of Zero Waste Scotland, who produced the report, said: "Our aim should be to make sure that if the survey published today is repeated in 10 years time, its results would be radically different.
"That will need radical action on many levels, from encouraging people to reduce their waste and recycle more, to working with manufacturers to make things easier to recycle, and supporting councils and recycling firms to increase collections and build new recycling facilities."
The Zero Waste campaign was launched at Blair Drummond Safari Park, near Stirling, by Environment Secretary Richard Lochhead.
It will feature road shows and a six-week advertising campaign to encourage Scots to recycle more.
