 Cambridge, UK & Palafolls, SpainUnder a recently signed agreement, Aqdot, the specialist chemtech company, will install a modular manufacturing system at Menadiona’s Palafolls site.

AqFresh™ is effective wet or dry and can be extruded into plastics and fibres to remove product odours as well as environmental pollutants and smells. Aqdot has designed its modular manufacturing system to be able to straightforwardly ‘plug into’ manufacturers’ facilities globally, enabling local supply and greater supply chain security.
