Our Services

Research, pilot projects, and evaluation


  • Evaluated four statewide Extended Producer Responsibility (EPR) programs in Connecticut. Collectively, the programs diverted more than 26 million pounds of materials from waste, saved municipalities over $2.6 million per year, provided services worth another $6.7 million, created more than 100 jobs, and reduced greenhouse gas emissions by more than 13 million kg of carbon equivalent.

  • Conducted the first-in-the-nation computer take-back pilot with Staples and the U.S. Environmental Protection Agency.

  • Conducting a 2018 Drug Take-Back Pilot Program to collect unused medications from five hospitals serving rural New York State.

  • Developed the Pesticide Stewardship Briefing Document and Extended Producer Responsibility for Household Hazardous Waste report to serve as a basis for discussions on end-of-life management for these products in the United States. We have also developed briefing documents for pharmaceuticals, medical sharps, paint, batteries, tires, carpet, fluorescent lamps, thermostats, mattresses, gas cylinders, phone books, radioactive devices, and other products. These served as the basis for PSI’s multi-stakeholder facilitations that collaboratively developed solutions to management problems.

Facilitation and consensus building


  • Mediated two multi-stakeholder agreements that led to a model paint stewardship bill now implemented in eight states and the District of Columbia. This was the first national product stewardship consensus agreement in the U.S., and was signed by the paint industry, state and local government agencies, recyclers, and others.

  • Laid the foundation for pharmacy drug take-back through multi-stakeholder dialogues and lobbying Congress to change the federal Controlled Substances Act and DEA regulations to allow pharmacies to take back controlled substances (including opioids).

  • Planned and facilitated a day-long workshop for North Central Texas Council of Governments to develop a regional strategic plan for pharmaceutical take-back.

  • Convened the 2017 NY Textiles Summit drawing together manufacturers, retail brands, recycling/reuse organizations, the fashion industry, state/local government, researchers, nonprofits, and consumers in an interactive event exploring upstream and downstream challenges to the reuse and recycling of textiles. The event developed an emerging network among stakeholders throughout the product lifecycle.

  • Planned and facilitated hundreds of state, regional, and national multi-stakeholder meetings, conference calls, and events on more than 20 products, including batteries and pesticides.

Build product stewardship capacity through education and empowerment


Legislative technical assistance, analysis, lobbying, and stewardship models


  • Develops model elements of product stewardship bills, including the Elements of a Model All Battery Bill. PSI invented this technique to build consensus among stakeholders with widely divergent views to produce a model policy that can be turned into legislative language.

  • Developed a solutions platform to improve New York’s electronics EPR law by integrating input from multiple stakeholders.

  • Created a fact sheet on carpet stewardship to educate New York legislators about the importance of carpet stewardship legislation.

  • Submits testimony and public comment letters on bills and stewardship plans for multiple products, including electronics, paint, pharmaceuticals, packaging, mattresses, HHW, carpet, mercury thermostats, and others.
