The Waste and Recycling Industry​

The waste and recycling industry has grown and evolved significantly since the early days of the twentieth century and while more women are coming into the industry, more needs to be done to both attract women into the industry and to equip them to take on leadership positions. This organization, founded by industry experts Rachel Oster & Erin Merrill was created to ensure women have the tools and support they need to be successful leaders in the industry.

The WISR Story

WISR was created from a need to bring together women from the various stakeholders who make up the waste and recycling industry.  After co-founders Erin Merrill and Rachel Oster left their corporate positions to start their solid waste consulting firm, they sought out to find a community of women from all throughout the waste and recycling space for networking and professional development.  To their surprise, an organization that brought together women from all facets of the waste and recycling space – private industry, government, consulting, media, academia, students, and those who are just interested, did not exist.  In 2017, WISR was born.  Today, WISR includes members from all over the United States and frequently receives inquiries from all over the world.
