ink and glues from waste paper
    #2410791 - 03/09/04 01:01 PM (14 years, 1 month ago)

just wondering if anyone has any resources on the glues used to make corrugated cardboard? and whether or not toxins from them or ink (if toxins exist) are absorded into mushrooms...
also i know some colored magazines use mercury to color the pages and i've seen oysters growing on magazines...any ideas on whether or not the mercury is absorbed? thanks

As far as I know you can use corrugated cardboard or normal newspaper without problems. Usually the ink consists of soy oil and some other stuff that is not harmful. But the colored, glossy magazines contains stuff ( like heavy metals ? ) that accumulate in mushroom tissue and therefore should be avoided. Just my two cents ...

i typed up this big redundant reply and backed it off to say ragadinks is right on. i understand corrugated glue to be regulated to be non-toxic unless otherwise clearly stated on the material. if you can contact the printer of a paper they will tell you what the ink consists of but soy inks are the norm by and large.

I think it depends on what mushrooms you are growing. Some mushrooms have been shown to be super accumulators of heavy metals, while others can be used to break down toxic wastes without effecting the edibility of the fruit. Paul Stamets has done a lot of research in this area for mycoremediation. The newest GGMM has more info on this. Stamets reccomends testing the individual strain on your selected substrate to see if it accumulates the heavy metals or not. (which is beyond most of our reaches financialy)

It is true that mushrooms break down certain toxins, but all living tissue accumulates heavy metals. Mushrooms, animals, and plants all accumulate and concentate heavy metals in their tissues, flowers, and organs.
