Evaluating Technology

DTSC's Technology Development Branch focuses on evaluating new technologies and alternatives to treat, recycle, clean up, and eliminate or reduce hazardous waste at its source. Through demonstration projects, data analysis, and life cycle assessments, these scientists and engineers provide support to other DTSC programs and help developers bring their ideas to market.
Technology Development
  • Extended Motor Oil Service Intervals (High efficiency oil filter study) 
    A recent study provides strong evidence that oil analysis programs, higher quality motor oils, and more efficient filters will protect engines from wear and lead to significant cost savings. Less frequent oil changes will also help to keep fleets on the road and reduces motor oil and labor costs. Oil analysis helps to determine the optimum oil change frequency and can provide early diagnostics for engine wear.
  • An Assessment of Zero Valence Iron Permeable Reactive Barrier Projects in California  
    This report investigates the performance of PRB technology implemented to remediate chlorinated solvent groundwater plumes at California hazardous waste sites. Ten zero valent iron PRB sites were evaluated in this report. A copy of this report is available online here. Any questions or comments concerning this report should be directed by e-mail to jmuegge@dtsc.ca.gov.
  • Nanotechnology 
    What is nanotechnology?  Why is DTSC interested in it? The Technology Development Branch has created an informational web page to try and address these questions and provide useful links to other sources on the Internet.
  • Life Cycle Assessment Projects
    A standardized tool increasingly used by businesses, life cycle assessment provides DTSC a way to assess a range of environmental impacts of a product, service, or process not normally considered
  • Evaluation of Non-Chemical Treatment Technologies for Cooling Towers at Select California Facilities
    This report evaluates to two non-chemical treatment technologies on their claims to  maintain a water chemistry that prevents scale and corrosion problems and inhibit adverse bacterial growth in cooling tower systems.   A copy this report is available here (Report, Appendix A, Appendix B, Appendix C, Appendix D, Appendix E).  Any questions or comments concerning this report should be directed by e-mail to sdavis@dtsc.ca.gov.
  • Perchlorate Contamination Treatment Alternatives
    Specific treatment alternatives for perchlorate contamination that have been implemented full-scale, demonstrated or are being researched are described in this report. We update this report as new information becomes available. If you have information that you believe should be included in the report, please send us an email at jwesnous@dtsc.ca.gov
  • Fireworks Treatment Technologies
    The Technology Development Branch is helping local law enforcement manage confiscated fireworks by identifying and evaluating potential treatment technologies.
  • On-Site Fluorescent Lamp Crushers
    The Technology Development Branch in partnership with the U.S. EPA are evaluating small drum-top lamp crushers as possible alternatives for managing spent fluorescent lamps.
  • Los Angeles Jewelry Mart Pollution Prevention
    Using research conducted in the Los Angeles Jewelry Mart District, DTSC's Office of Pollution Prevention and Technology Development (OPPTD) has developed a series of Pollution Prevention (P2) guides for Jewelry Manufacturers.  
  • In-situ Bioremediation of Chlorinated Solvents in California
    This report investigated the status of in-situ bioremediation technology used in California to remediate groundwater specifically for chlorinated solvents.  Pilot and full-scale sites were identified based on record searches at several government agencies and is not considered a comprehensive inventory of these types of projects.  Five sites were selected for more detailed evaluation.  A copy of this report is available online, but due to its large size the download may take several minutes (PDF 8.05MB, Download Time: 41 min. 55 sec. @ 28,800 bps, 18 min. 43 sec. @ 56 Kbps, 1 min. 40 sec. @ 640K-DSL).  An electronic copy of the report can also be obtained by contacting us via email at sdavis@dtsc.ca.gov.
Technology Certification Program

Due to the current budget shortfall for the State of California, and associated budget uncertainty, DTSC is not accepting any new applications into its Hazardous Waste Technology Certification Program. This program certified the performance of hazardous waste environmental technologies.

  • Cal/EPA-U.S. EPA Environmental Technology Verification Pilot Program
    The goal of this joint Cal/EPA-U.S. EPA pilot program is to develop a national model to test, evaluate and verify technologies for pollution prevention, treatment, emission control, and monitoring.
  • Public Notices
  • Environmental Technology Certifications
    The Technology Advisory is a brief summary of the technology certified under the Technology Certification Program. The Certification Notice is an excerpt from the California Regulatory Notice Register of the actual certification notice, as published by the California Office of Administrative Law (OAL).
