I'm interested in finding ways to decrease the fraction of my household waste that goes to landfill. One strategy for achieving this objective - in part if not in whole - is to change my purchasing habits, basically to buy fewer items that involve non-biodegradable materials and sort waste at a minimal level (compostables from non-compostables, plastics from metals, steel/aluminum/tin/etc., etc.)
I'd like to explore ways of processing and repurposing items that aren't recyclable in the conventional sense (e.g. plastic cereal bags, thin shell packaging, etc.). This is in part because it seems like it could be practical, if not immediately then in aggregate at a sort of population level over time, and in part because it seems like it could be fun (or at least instructive.)
Are there forums or publicly maintained websites/website-communities where an aspiring amateur home recycler such as myself might find guidance and/or share advice?
