Do you dumpster dive recycling bins for packaging?
If you don’t, you should!
Find businesses that are clean and whose owners value clean bins.
Or perhaps discuss taking all their packaging for them so they don’t need a bin.
You’ll need to be reliable though.
Creative ways of saving money, saving the planet and building community connections should be a priority when you’re starting out. That’s what resourcefulness is. Making the most of your resources, not insisting you must have more resources to make progress.
