Lorna Slater addressed Holyrood on Wednesday amid ongoing uncertainty over Scotland’s deposit return scheme (DRS).
The circular economy minister told MSPs the scheme would be delayed until at least 2025 following intervention by Westminster.
The UK Government has said an exemption to the UK Internal Market Act – which is needed to push ahead with the scheme in March – could only be granted if glass is not included.
First Minister Humza Yousaf previously branded the UK Government’s “demands” to remove glass from the flagship recycling scheme a “democratic outrage”.
He added that the scheme could be scrapped if Rishi Sunak’s government did not agree to remove the conditions.
Yousaf had set a deadline of 6pm on Monday in a letter to Prime Minister Rishi Sunak on Saturday, saying a failure to revoke the condition would put the DRS in “grave danger”.
He claimed the UK Government demands would have a detrimental impact on businesses in Scotland and threaten the viability of the scheme.
Under the new changes, only PET plastic bottles, and aluminium and steel cans will be included.
Similar UK-wide schemes are not set to start until 2025 and do not include glass bottles.
