Our history

Warden Biomedia is part of the Warden group. Established in 1957, Warden’s initial business was the chipping and selling of regranulated plastics, but it soon expanded its operations to include the design and production of plastic extrusions. In the early 80’s Amity & Co. became part of the Warden Group enabling Warden to manufacture and market their Biomedia range.

Since then, Warden Biomedia has actively pursued research and development to produce sustainable, eco-friendly filter media to maximise performance and reduce energy requirements for water, wastewater and biological treatment processes.
