CEO Guy Richardson explains the benefits of Huwa-San technology currently available.

Guy Richardson was introduced to Silver Stabilised Hydrogen Peroxide nine years ago and for the last three years has been working with the Next Generation of this Technology under the Brand name of HuwaSan. 
HuwaSan is a highly effective broad- spectrum disinfectant that is both stable and safe. It is this solution of Hydrogen Peroxide which has been stabilised using a proprietary ionic silver-based chemistry that makes it the most advanced silver hydrogen peroxide in the market. 

Customers often ask what does the brand name “HuwaSan” stand for well here is the official answer.
HuwaSan takes its name from Dr Hans Hungerbach the scientist who first developed the technology.

Hu/ Hungerbach

Wa/ Water

San/ Sanitiser

Huwa-San was first developed by Dr. Hans Hungerbach a Hungarian Scientist over 20 years ago and Roam Technologies in Belgium have spent the last 15 years developing it further and now have 185 distributors worldwide. 

Guy is extremely passionate about Huwa-San and believes its application can be used in many different industries, including greenhouses.  HuwaSan is ACVM Registered -P009479 as a Bactericide, Viricide, Fungicide and is the first choice of many growers here in NZ when they are looking for a more environmentally and sustainable product to replace old toxic options. Huwa-San is used for  Bio-Film Removal,
Packhouses (post- harvest washing), Greenhouses, Irrigation water, Room Disinfection and Food Processing areas to name a few.  

Guy summed it up by saying,” increased awareness among consumers in combination with strict regulations are increasing the demand for ‘clean and green’ produce. Crops will have to be grown with less use of pesticides and fungicides. The development of alternative ways of managing pests and diseases (e.g. IPM, Integrated Pest Management) is crucial. In combination with good hygiene management of water and environment, this will help the growers to deal with diseases of viral (TMV, CMV, …), bacterial (Agrobacterium, Xanthomonas, Erwinia, Clavibacter) or fungal origin (Fusarium, Phytium, Phytophtora, …) in a more sustainable way and this is where HuwaSan is ready to lead the way. 



What is Huwa-San?

Huwa-San is a disinfectant based on Hydrogen peroxide.

Hydrogen peroxide (H2O2) is a transparent, colourless and odourless disinfectant liquid which is mixable in any ratio with water.  After reaction, it decomposes into water (H2) and oxygen (O2).  The main difference between Huwa-San and regular hydrogen peroxide, is in the presence of a stabilising agent.  As H2O2 is not stable and slowly decomposes into oxygen and water, a stabilizer in the form of a small amount of silver is added.  The silver is used to increase the stability of the hydrogen peroxide solution (H2O2+Ag).
The procedure of combining hydrogen peroxide with the silver stabiliser is unique worldwide and is based on the original Huwa-San technology.  The Technology is so unique as no other stabilising agents, like acids for instance, are needed to stabilise the peroxide.  All of this makes Huwa-San technology products non-residual and extremely powerful disinfectants.

Huwa-San is a one stop biocidal product that is effective against bacteria, fungi, yeast, spores, viruses and even mycobacteria and therefore can be used in many applications.
Over the last 15 years, Huwa-San products were tested extensively on lab-scale and on many field trials all around the world.   As a result, Huwa-San products meet the most rigid standards for disinfection.
