Abstract: The present invention relates to esterases, more particularly to esterase variants having improved activity and/or improved thermostability compared to the esterase of SEQ ID NO: 1 and the uses thereof for degrading polyester containing material, such as plastic products. The esterases of the invention are particularly suited to degrade polyethylene terephthalate, and material containing polyethylene terephthalate.
