One of the things that made me think of doing this was Nat Friedman's (GitHub co-founder) project, PlasticList[1].
The idea was to give consumers real-world data to inform their decisions around avoiding/minimising microplastics. Some sources are orders of magnitude worse than others, so this potentially allowed people to eliminate a large portion of their exposure by just avoiding the products with the largest amounts.
This was a project that someone wanted to happen and was willing to pay for, but for whatever reason wasn't being done by the usual institutions (universities, governments).
The idea of this post is to give people who have money a way to find out about other projects that fit this shape, so they can fund them.
