Are there any databases or search filters for published peer-reviewed articles, particularly concerning environmental issues, that are neither affiliated with nor funded by corporate interests?

I am trying to find peer-reviewed articles on the history and impact of plastics pollution. Most articles I have found either have authors affiliated with petroleum/packaging/fast-moving consumer good companies, were commissioned by those companies, or received funding influenced by those companies.

I am not asking whether industry-sponsored papers are less accurate, as this has been asked before. I understand that high-quality independent research can emerge from (and be enabled by) corporate funds, and that every funding source has biases of some kind.

I would just like to know how to find articles whose authors and funding have no corporate ties.

Additionally, I understand that not all connections with industry are apparent. As an example, one article encouraging plastics packaging had no author affiliations but received funding from a major English research council. Although this council describes itself as independent, its directors' declarations of interest contain many corporate ties, including to petroleum giants. Since this is indirect, I would not expect it to qualify as "industry-sponsored."
