A NEWLY developed technology provides wood fiber composite with antimicrobial attributes, enabling the material used for semipermanent hospitals to beat today’s standards for regular hospital environments
Parx Plastics and Aviplast WFC/Deltawood, developer of the material, have successfully added antimicrobial property to the innovative material, providing it with antimicrobial property of up to 99% within 24 hours, higher than current hospital standards.  
Parx equips the material with a kind of immune system against bacteria to make it 100% safe for humans and the environment.  The unique biocompatible technology, recently identified by the European Commission as being from one of Europe’s top tech startups, does not use any harmful substance, biocides or heavy metals such as silver, or nanomaterials. It instead uses one of the most abundant trace elements in the human body to enable an intrinsic change that makes the surface hostile to bacteria. 
This intrinsic property of the technology prevents leaching out and provides a permanent antimicrobial protection with a high efficiency against Escherichia coli (E. coli, gram-), Staphylococcus aureus (gram+) and Candida albicans. Antimicrobial tests conducted by the University of Ferrara, Italy on the surface of the wood fiber composite and following the international standard ISO 22196 show 95.73% initial results. 
“This is excellent result coming from our initial tests on this material,” said Michael van der Jagt of Parx Plastics, “We know now what to do to reach our target of 99% in our next round of tests.” 
Aviplast WFC/Deltawood general manager Wim Derksen said, “We have been an innovator in the market providing this semi-permanent hospital concept, but now we are taking a big lead ahead with this permanent and safe antimicrobial technology.”
The wood fiber composite, which consists of 75% wood fibers from recycled waste or rest wood in combination of 25% plastic (PP) resin, has been used to build emergency care units to replace hospitals in the Philippines destroyed by typhoon Haiyan. Keeping the hospital environment cleaner by providing a safe concept really counts in areas that are already challenged by circumstances.
