A £27 million recycling centre in Aberdeen is producing lower-quality materials than its counterparts, new figures show.
The Altens-based Aberdeen facility was opened in October and sorts waste into bales for reprocessing.
However, the most recent quarterly statistics from the Scottish Environment Protection Agency have revealed 31.4% of its output is contaminated with “non-target” materials, or non-recyclable materials.
The average for the 13 other sites in Scotland was 8.4%.
Some have argued the issue stems from the council’s move to mixed system collections. Since last March, residents have been able to put recyclables in one kerbside box.
Retired environmental scientist Ishbel Shand said: “There seems to be a problem with the plant, as what is coming out contains an enormous amount of non-target and non-recyclable material.
“A mixed system may be cheaper to collect, but it will be difficult to re-sell or re-use poor-quality recycling so it is likely to end up being landfilled or burnt.”
