Clean Scrub Technologies (CST) is a recently formed company that is rapidly becoming an industry name in carbon dioxide sequestration. Through extensive testing and research, CST has developed a new and innovative closed loop system and gas pretreatment systems that recycles reactants used in the process and unconventional low energy solids separation methodology for essentially 100% percent removal of carbon dioxide from any gas stream. The process does use conventional dehydration from slurry to powder that produces a non-toxic and non-hazardous waste that can be used in any number of applications such as soil additive, fertilizers, and treatment of noxious odors. CST has also surpassed current industry limitation in the ability to specifically design and augment our technology into a client’ technologies by personalized bench and pilot scale application that successfully moves into full scale commercial construction, development, and implementation with guaranteed results immediately upon initiation.We thank you for opportunity to discuss this novel and innovative technology that is rapidly fighting climate change and helping one day at a time to make a difference in the world we live in.For more information or to schedule an introductory call, please feel free to contact us either via LinkedIn, email or phone.Robert Richardson, PhD CEO at (530).474.4819 or via email at robert@cleanscrubtechologies.comORTimothy R.

Providing cost effective, green and innovative air quality solutions.Dr. Robert Richardson has skillfully led PRDD through 28 years of successful environmental problem solving for a wide range of industries. PRDDs' scope of services is tailored to the client’s requirements. PRDD efficiently handles all aspects of a project and contributes skills that complement the client’s resources. We offer consulting, testing and a complete scope of design/build services. Our goal is to provide only those services that optimize the project performance.• PRDD’s innovative solutions are the result of continued research and development.• PRDD’s success rate is based on completely understanding the project with analytical testing before a solution is formulated. • PRDD provides innovative solutions that are more efficient, less expensive and greener than alternatives.

The Know-NOx process was developed in 2011 by PRDD then moved into its own company.The Know-NOx process developed by Dr. Richardson, cost effectively treats NOx (both NO and NO2) more effectively and in a smaller footprint than other available technologies. This process also simultaneously oxidizes SO2.The unique patented Know-NOx technology reduces NOx and SO2 emissions by up to 99.9%. The Know-NOx process is configured to optimally meet a client’s abatement requirements. Dr. Richardson configures each application of the Know-NOx process to optimally meet the client’s requirements. Know-NOx can be a standalone process or be integrated into other abatement processes.As the most effective NOx abatement technology available today, Know-NOx has the propensity to save hundreds of thousands, if not millions of dollars in the long term from emission reduction credit sales as Know-NOx exceeds EPA requirements.• Know-NOx treats NOx from any industry such as industrial or pharmaceutical manufacturers. • Know-NOx also treats furnace and engine exhaust.
