Commercial waste is no longer accepted at any of West Lothian's five recycling centres, which have now been renamed Household Waste Recycling Centres (HWRCs).
The move is part of changes at HWRCs that aim to protect both the environment and vital council services by improving recycling rates and reducing landfill costs.
Residents are advised to make sure they know the new rules when they visit a HWRC, such as bringing along valid ID such as a driving license and proof of residence.
Valid ID can be either a current photo driving licence, identity card or passport and a recent (from the last 6 months) bank statement, council tax, or utility bill. All documents should have matching names and addresses.
West Lothian HWRCs are located at Blackburn, Broxburn, Linlithgow, Oakbank in Livingston and Whitburn, and are open Monday - Sunday, 9am - 7pm, from June to September. Please note last entry is at 6.45pm.

A West Lothian Council spokesperson said: "We now only accept household waste at our recycling centres, with no commercial waste allowed.
"Commercial waste is any waste produced by commercial contractors including organisations, commercial premises, traders, charities, landlords, restaurants, hotels, etc. even if it originates from residential properties.
"This should have no impact on the vast majority of local residents for their household waste, but individuals are advised to check in advance if they are affected.
"The small number of local residents who use liveried vehicles with commercial logos or signage on them, to dispose of their household waste will need to apply for a permit to continue to use our HWRCs. For full details, please visit Residential Permits for Recycling Centres.
"Local residents who have hired a van to dispose of their household waste will need to bring along a copy of their hire agreement as well as valid ID, such as a driving license or passport and recent council tax or utility bill."
Commercial waste in West Lothian can be disposed of at 14 local sites managed by private operators, with further information available at Trade Waste at Recycling Centres
