Who We Are

Our Subject Matter Experts (SMEs) regularly "check in" and are available to answer your questions, comment on our posts, and review materials that are sent to us. You can click on their names to review their LinkedIn work histories, degrees, areas of expertise, publications, etc. We are always looking for experts! Please provide names and career histories to Bob Lilienfeld.

Some of our experts are precluded from being listed as SMEs for legal reasons. We are grateful for their personal, pro bono interest and participation. They're included below as Personal Contributors.

Our Advisory Board manages day-to-day activities, facilitates and moderates discussions, and provides relevant input in fields where a Board Member has specific expertise.

Who We Are

How We Work

We strive to always be thoughtful, honest, understanding, global in scope, and value-neutral.
There are no "one size fits all" solutions to sustainability issues. While problems may be global, solutions may need to be local, based on a variety of factors including infrastructures in place, economic conditions, political considerations, and societal norms.

We welcome all participants and treat them with respect.
Any poster who is disrespectful of others will have that post removed and will be removed from the network following a second incident.

We respect your right to post politically related statements on your own network.
SPRING is not interested in your politics and does not allow postings of an overtly political nature.


We do not accept advertising or donations of any kind.
Our SMEs are available for consulting and review work, and any financial arrangement must be worked out with them individually and reported to SPRING to ensure that future conflicts of interest are avoided.

We reserve the right to peer review submitted studies.
Our audience trusts us to provide scientifically accurate information with findings, conclusions, and recommended actions that are supported by the appropriate data.

Always review the LinkedIn credentials of those who post.
And remember that expertise, by definition, is limited. A football coach may be a sports expert, but that doesn't make them a packaging expert. Similarly, if discussing climate change, experts in the field of climatology or meteorology would normally have more credibility than biologists or chemical engineers. (Of course, degrees held, schools attended, employment history, and papers published all can make a difference.)

We ask that you please keep your posts and replies on-topic (sustainable packaging).
However, we gladly accept job and consulting postings in the packaging field.
