Has anyone found any options to recycle safety vests, or discovered an upcycling option for them?  We are about to replace all of our vests company-wide and will have thousands that we don't want in the waste stream and we don't want to be reused as safety vests.  Any thoughts or ideas would be great!

Thanks and I hope everyone is... Read more

Hey Peer Network! Curious, if we can crowd-source a solution here for the pervious pavers at our Omaha office (climate zone 5A). Apparently over the years we've tried to add different kinds of fill here (gravel) but it keeps... disappearing. Any recommendations with either a replacement product or fill item?

On a large sports project, we worked with the structural engineer to spec low carbon / high SCM concrete mixes.
