Overview

  • TURI Mission

  • 5 Chemicals Alternatives Assessment Study – Overview

  • Study Process

  • Chemical Uses

  • Alternatives for Selected Uses


Massachusetts toxics use reduction institute l.jpg
Massachusetts Toxics Use Reduction Institute

  • MA Toxics Use Reduction Act 1989

  • Use Reporting

  • TUR Planning

  • Manufacturers and service industries

    • 10 employee and 10,000/25,000 lb threshold, except PBTs

  • TURA agencies: TURI, Office of Technical Assistance, and DEP

Massachusetts Toxics Use Reduction Institute

  • Mission:

    • Research, test and promote alternatives to toxic chemicals used in Massachusetts industries and communities

    • Provide resources and tools for a safer place to live and work

    • Promote economic competitiveness

  • Via research, training, technical support, networks, lab testing and information


Turi 5 chemicals alternatives assessment study l.jpg
TURI 5 Chemicals Alternatives Assessment Study

  • The Commonwealth of Mass. has requested that TURI assess the feasibility of adopting alternatives to 5 chemicals:

    • Lead

    • Formaldehyde

    • Perchloroethylene

    • Hexavalent chromium

    • di-(2 ethylhexyl)phthalate (DEHP)

  • Final report due to legislature June 30, 2006


Legislative request l.jpg
Legislative Request

  • For each substance:

    • Describe the significant uses in MA

      • Manufacturing

      • Products

    • Identify possible alternatives, proven and emergent, for selected uses

  • For each alternative chemical or technology, assess their potential to serve as substitutes for specific applications:

    • Technical feasibility

    • Economic feasibility

    • Environmental and occupational health & safety evaluation


Legislative request7 l.jpg
Legislative Request

  • Economic Analysis

    • Study economic opportunities and impact on employment level and economic competitiveness of the Commonwealth as a result of adopting substitutes

      • The information available to us for specific alternatives is limited and often varies significantly by facility and application

      • Undertake survey of experts to discuss major factors influencing economic opportunities and impacts


Turi goals l.jpg
TURI goals

  • Conduct an objective and scientific alternatives assessment

  • Be transparent and open

  • Get input from major stakeholders in Massachusetts

  • Produce results that will help companies and consumers make better decisions


Turi goals9 l.jpg
TURI goals

  • Results will not

    • Advocate or state preference for any particular alternatives

    • Recommend bans or phase-outs of any chemicals or any uses of chemicals


How does the study relate to tura l.jpg
How does the study relate to TURA?

  • Options Assessment

    • TUR Planners and the TURA Program have 15 years of experience researching, investigating and developing alternatives to the use of toxic chemicals

  • Methods for Assessment

    • TURI and UMass Lowell have researched and developed alternatives assessment methodologies

    • still striving to outline a practical, efficient, and sufficiently accurate tool for TUR Planners to assist in decision making


How does the study relate to tura11 l.jpg
How does the study relate to TURA?

  • TUR in 2006 increasingly focuses on materials substitution

    • Economic competitiveness tied to:

      • International materials restrictions

      • Customer requirements

    • Elimination goals for PBTs

    • Much of the “low hanging fruit” has been picked

    • Consumer focus on toxics in products, body burden studies


Setting priorities l.jpg
Setting Priorities

  • Schedule and Budget require assessing a subset of chemical uses and alternatives

  • Focus on uses and alternatives where assessment results will be of most value

  • Stakeholder input used to select high priority uses and alternatives
