The Recycling Drop Off Centre will operate for an extra hour in 2018.
The Wetherill Park facility will now open on Saturdays from 8am to 4pm. Currently it is opened from 8.30am to 3.30pm.
The motion for extended hours was put forward by Councillor Paul Azzo in July.
The centre, located at the corner of Davis Road and Widemere Road, is for Fairfield residents only with several items accepted free of charge.
