which bins can take it?
- hot pile yes
- cold pile yes
- worm bin yes
- bokashi no
- tumbler yes
- curbside yes
why?
Construction paper is made from coarse mechanical pulp — wood ground up with the lignin left in — which makes it weak, absorbent, and fast to rot; it's the same reason it fades in sunlight. Classroom dyes and washable paints are formulated for kid safety and add nothing harmful. A crayon drawing contributes a film of paraffin and pigment measured in fractions of a gram, which soil microbes eventually digest too.
how to prep it
- Tear sheets into strips or squares
- Peel off googly eyes, glitter glue, and tape from craft projects
watch out for
- Heavily glued or glitter-covered art projects belong in the trash — dried school glue breaks down poorly and glitter never does.
quick answers
Do the dyes in construction paper leach into compost?
The color bleeds when the paper is wet, but construction-paper dyes are the same low-toxicity classes used across school supplies and they degrade with the fiber. Finished compost shows no trace of them.
