Scotland's waste sector is on the verge of a crisis which could see rubbish piling up on the streets, experts have said.
Industry representatives are due to meet ministers to discuss their concerns but say there's no short-term solution to avoid the crisis.
The Scottish government said was working with stakeholders to maintain resilience and identify contingency arrangements should they be needed.
Landfill capacity in Scotland has been shrinking as operators wind down their operations ahead of a forthcoming ban on sending black bag waste to landfill sites.
Last year there were 10 sites which took in most of Scotland's residual waste – the material left over after recyclable and compostable materials have been separated out.
The problems have been exacerbated by the breakdown of Glasgow's main incinerator at Polmadie, which has been out of action since April.
Much of the city's household waste is now being diverted to a large landfill site at Mount Vernon - but its operator, Patersons, says it only has a few months of space available for burying the rubbish.
The amount of rubbish being processed there has increased from about 2,000 tonnes to 5,000 tonnes a week.
Several sites in the north of England, some of which are understood to have received waste from Scotland, have been shut down by the Environment Agency following investigations into suspected illegal waste activity.
Landfill manager David Balmer said it was possible that Scotland would quickly run out of landfill space.
Waste consultant Alasdair Meldrum, of Albion Environmental, says he has not seen such a looming crisis in almost 40 years of working in the industry.
