Composting Non-Organic Produce

sorry if this has been asked before - I used the search function, I swear.

I have been looking around where I live for a solid source of compost, and I found that the supermarket around the corner has quite a big bin of it - every day, and as an added bonnus lots of good, fresh, edible stuff. Got 10 loafs of good whole bread yesterday, packaged, some of it organic - awesome.

Now I am a bit unsure - most of it is not organic stuff after all. How bad would it be to compost it and grow stuff with it? Am I tapping into a useful source, or just slowly adding poison to my wonderful garden? Would you do it? I'd use most of it to grow tomatoes, I think.

Thanks all

Everyone has their own level of acceptance regarding contaminants. Is a tiny amount of preservatives in a few loaves of commercially produced stale bread going to make you lose sleep worrying about your compost heap? Do you support the ideal of organics to the extent that Zero Tolerance is what you live by?

Are there ways to process the grocery store material in a manner that mitigates the contaminants? Feed the stuff to chickens, use the chicken manure to raise worms, use the worm castings to raise flowers to attract bees to pollinate your organic crops.

It is up to you to determine what you will accept.

Ken, thanks for framing my question, was very helpful I don't yet know what I am aiming for. this 100% pure organic idea is kinda attractive to me, but then it's also such a(n unnecessary?) pain.

Chris, thanks for the video, it was just what I was hoping to hear.

Chris - Great find on Geoff's video, so this line of thinking should also encompass the use of 'Humanure' as is Joe Jenkin's philosophy. Apparently, in just normal composting Geoff is saying that 50 million bacteria and fungi are busy breaking down and/or encapsulating/binding to carbon any toxins and making them inert. Boosting this 'normal' process with Bokashi and extra Forest Bacteria and Fungi, would further assure that this does happen and doing so very quickly.
