attention and have product container or label

(of chemical substance) at hand.

For the sake of environmental

protection: Dispose of contents/

Notes on disposal for chemistry experiments

The very small quantities of minimally

hazardous chemicals used in these experiments

do not pose any great danger to the

environment.

››› The liquids can be poured directly down the

drain. Be sure to rinse well afterwards so that

no residues remain behind.

››› Solid waste, such as chestnut or buckeye tree

bark, leftover foodstuffs, paper towels, or filter

paper, can be thrown into the garbage can (not

the kitchen trash).

››› Materials that have been soaked in chemical

solutions (e.g., coffee filters or paper towels)

should be carried with the double-headed

measuring spoon to the household garbage.

Important! Do not grab with your hands!

››› Chemical residues in the chemical vials can be

taken to a hazardous waste disposal facility

with an adult, if you no longer need to use them.

That way, they will be sorted along with other

laboratory residues and disposed of properly.
