What if
cardboard was to be pre-soaked (more or less re-pulped) and then added directly
to the compost tea brewing process?
Thoughts?

Shredded Paper.
Hi Bill -
Paper is cellulose for the most part, and depending on the quality of the
paper, there may be some materials that help the paper have a finish, make it
glossy, stick, etc. Those are the materials you need to ask questions
about - the glues, tackifiers, dyes, and inks. The paper itself is plant
material, and fairly recalcitrant, hard-to-break-down carbon-containing
material.
Most inks used in this century are soy-based inks, but even as recently as the
1980's, some inks were heavy-metal based. Don't use paper with ink that
you are not certain is safe around your plants, or in your compost bins.
Cardboard is less-refined paper, usually thicker, longer fiber, and several
layers, glued together with a material on which certain bacteria and fungi grow
quite well.
Addition of paper and cardboard usually help fungi, and often some very
beneficial fungi, grow. Whether you layer the cardboard down as sheets to
help block sunlight getting to weed seed, or you shred the paper and cardboard
to allow more rapid decomposition (if you have bacteria and fungi in your soil
or compost), fungi will eventually be the majority of the organisms
selected.
If you aren't careful about aeration, the fungi you grow might be Fusarium,
maybe Pythium, or other disease fungus. So, make sure you are getting
good earthworm or microarthropod numbers in the material to build air
passageways and maintain aeration. If you keep things well-aerated, if
moisture isn't too high, or too low, paper and cardboard can make great food
resources for beneficial fungi.
We find that addition of paper and cardboard to wormbins (not-too-wet-worm
bins), help very beneficial fungi grow quite well.
