The system will be put in place at the Weston-super-Mare, Backwell, and Portishead recycling centres.
North Somerset Council believes the system will make visits “faster, safer, and more efficient.”
Weston recycling centre will be the first to operate under the online booking system, with Backwell and Portishead to follow.
The scheme is expected to deliver environmental and financial benefits by cutting carbon emissions from idling vehicles, reducing unauthorised use by people from outside the area, and making sure commercial and DIY waste is managed correctly.
Cllr Annemieke Waite, North Somerset Council’s cabinet member for planning and environment, said: “Alongside our comprehensive kerbside collections, the recycling centres are an important way for our residents to get rid of their unwanted items responsibly.
“By introducing a simple, quick online booking system, we can reduce queues, make visits easier, and ensure our sites are working as efficiently as possible for everyone.
“Essential repairs are needed at Weston-super-Mare’s recycling centre later this year, so having a booking system in place will also help to manage the site safely and keep queues to a minimum during this period.
“This change brings us in line with our neighbouring authorities, who all have successful and well-liked booking systems in place.”
More information, including how to book, will be shared closer to the time of implementation.
This initiative is part of the council’s wider efforts to improve services, reduce waste, and respond to the climate emergency.
It supports commitments in North Somerset’s Waste Strategy and Climate Emergency Action Plan.
Residents can check opening times, see what they can bring, and find answers to common questions about the new booking system at the North Somerset Council website.
