Like to know the formal steps in disposing of the chemicals whose shelf-life is over. The chemicals are basically Acids, both Organic and Inorganic, and Hydrogen peroxide.
Normally you'd have dedicated Safety people who would manage the disposal of lab chemicals, but if you're inclined to have all the fun to yourself, you may wish to consult this manual: Prudent Practices for Disposal of Chemicals from Laboratories, http://b-ok.org/book/695900/7d5598
Another good book is M.-A. Armour, Hazardous Laboratory Chemicals Disposal Guide, Lewis Publishers; however, that's not readily available. It lists specific procedures on a chemical-by-chemical basis, so it would be the best for your purposes.
Dear Sebastian,
Chemical disposal usually follow a standard procedure. You can develop yours by going through the guide provided by Julius Pavlov.
This SOP might also be helpfull

Typically you would neutralise acids and bases to make their salts, which can then be disposed of more safely and cheaply (if you have both acids and bases to dispose of, you can neutralise one with the other to save money) For hydrogen peroxide, if it has passed its shelf-life by a long way, test it's pH - it may well have fully decomposed and you'll only have a bottle of water left which will need no special disposal route.
