Sustainability
We endeavor to be transparent, collaborative and scientifically rigorous in our approach. We are pleased to share the following scientific facts that we believe support our conviction that PURETi is safe for humans, safe for the environment and a great new tool for sustainability and health.
PURETi UV-PCO technology cleans with light, not chemicals, and transforms surfaces into sustainable, self cleaning materials that greatly benefit the environment.
A revolutionary technology to reduce air pollution
PURETi is an exterior, spray application that uses the power of light to transform surfaces to combat pollution, significantly reduce NOx and create cleaner, healthier air. It is a safe, viable, simple and cost effective innovation that completes a comprehensive NOx reduction strategy.
Ease of Implementation and Maintenance
PURETi is highly durable and easy to maintain on a large scale without modifications to existing infrastructure. PURETi is spray-applied clear, dries invisibly and leaves no visible change to the surface upon application. Large areas can be treated in a single day or night, without construction activity and can be fully utilized by the public within hours.
Part of a Comprehensive NOx Reduction Strategy
PURETi is a state-of-the-art photocatalyst that compliments a comprehensive NOx reduction strategy. It is a viable, economical and easy to implement innovation that provides control “beyond the source” to help control post-tailpipe pollution. PURETi is beneficial at the point of reception, to provide another level of protection against the harmful effects of NOx.
Cost Effective Solution
PURETi delivers immediate and continuous results, making it among the most cost effective solutions on the market to control and combat the effects of NOx. Compared to other air quality solutions requiring extensive investment to achieve air quality improvements, PURETi can be implemented quickly and easily without costly infrastructure changes or economic disruption. When combined with more mainstream Air Quality policies, the benefits of: immediate results, speed to market, and ease of implementation make PURETi a cost effect solution to improve air quality within EU NO2 limits.
Life Cycle Analysis
Life Cycle Analysis (LCA) has been done and PURETi has been found to be environmentally beneficial in a broad and sustainable way. Prof. Marwa Hassan of LSU, in her peer reviewed 2009 paper on the LCA of Smog Reducing Concrete, found smog reducing concrete, despite the high carbon content of concrete, to be an environmentally beneficial product.
Prof. Hassan has studied PURETi's heterogeneous, water based surface treatment approach to creating photocatalytic surfaces for over 5 years. Her LSU team has found spray applied PURETi to be 2-4 times better at reducing NOx than photocatalytic concrete produced with embedded TiO2 nano powders.
Prof. Hassan stated further that the environmental gains created by PURETi (water and energy savings from reduced maintenance, NOx reduction, methane and VOC oxidation, and heat island mitigation through increased solar reflectance) far outweigh the carbon cost of the trace amounts of CO2 produced in the photocatalytic process.
Pollution Reversal
PURETi has been found to significantly reduce NOx (an indirect GHG and the key ingredient in acid rain and smog) in repeated studies with major American universities (SBU, LSU, WSU and U. of TX), state departments of transportation (LDOT and MODOT) and independent international test labs (the UK’s Queens International Photocatalyst Test Centre and Italy’s Ferarra University). One lane mile of PURETi treated road will remove 1 ton of NOx per year per Prof. Hassan of LSU.
Conclusion
PURETi is dedicated to producing the safest, simplest, most sustainable, credentialed and cost effective photocatalytic solutions in the world. We believe we currently do and we believe further that photocatalysis – the light activated acceleration of the natural process of organic degradation – holds tremendous power to be a healing force for man and planet.
PURETi works with universities, national labs and independent testing organizations on a daily basis to insure that our products are safe, effective and environmentally beneficial. This has been our practice since day one over ten years ago and this will continue to be our standard and our commitment as we move forward.
PURETi has been proven safe.
PURETi has been proven environmentally beneficial.
