Plastic Disclosure Project

Steering Committee

The work of the Plastic Disclosure Project is overseen by a global Steering Committee, drawn from investors and other stakeholders who support PDP's mission.  The Steering Committee oversees the development of the project, and provides advice to the management team.  The wide experience and network of the Steering Committee's members is a valuable asset for PDP. 


Bill Robberson

Bill Robberson

Bill has worked with the Secretariat of the Pacific Regional Environment Programme (SPREP) and the American Samoa Environmental Protection Agency (AS EPA) for over 20 years on the coordination and protection of water quality and natural resources in the Pacific Region.  His more recent work in American Samoa has focused on development and implementation of its Marine Debris Action Plan, including efforts to address the onslaught of solid plastic waste there and throughout the Region.  Bill also has extensive experience with the assembly, deployment and maintenance of solid plastic waste capture devices for outfalls, streams and rivers. 

One of Bill’s main efforts at Ocean Recover Alliance is program development for plastic footprint management and reduction within communities - engaging business, government and the broader public sector.  These efforts include solid plastic waste (SPW) collection methods and improvements; policy modifications; value-creation of programs for recovered materials; and technologies, equipment and programs which can reduce the total plastic-pollution waste-load being created.

In addition to his roles at Ocean Recovery Alliance, Bill is a founding member of the team working on development of ASTM (American Society of Testing and Materials) best practices and standardized laboratory & field methodologies for the collection, extraction and positive identification of microplastics in water and wastewater. 

Bill’s team is exploring the use of existing sensors/platforms and development of suitable new technologies for remote and in-situ plastic particle measurement (detection and identification), including pilot-scale and full-scale development and operational deployment of these systems.  Bill also leads an effort in development of a multi-entity collaborative 4D geospatial visualization platform and open-data sharing services to identify, track and manage sources of worldwide plastic pollution.  

Before joining Ocean Recovery Alliance, Bill served at the U.S. Environmental Protection Agency (US EPA) for 32 years, where he specialized in water quality protection and treatment; environmental data collection and geospatial situational awareness; emergency response management and contingency planning; and included more than two decades as the Oceania and Southwest U.S. Regional Response Team Coordinator.

Bill is a licensed Professional Engineer (P.E.) in the State of California, and he is the founder of Ocean P3 Systems, a veteran-owned business specializing in development and implementation of environmental protection equipment, tools and programs.  His knowledge and expertise in this space is an enormous asset to Ocean Recovery Alliance's work on both plastic footprint reporting via the Plastic Disclosure Project, and the Global Alert app/platform, for reporting trash hotspots anywhere in the world's waterways and coastlines.
