elindra and LF, we share so many similar recycling habits that I
had a good chuckle reading both your lists.
Ah well, here's my list -
Egg Crates - put aside and saved until I visit the Richmond
Market where I'll hand them all to the egg-seller there to
re-use
Newspapers, old magazines, cartons, the insides of toilet paper
rolls and kitchen napkin rolls - dump into the Recycle bin at the
back of the building
Boxes of products bought, if still in good condition - use for
storing knick-knacks
Old Towels - use as rags
Plastic bags - used to line my rubbish bin
Empty juice or beverage bottles - refill with water to chill or
to use as water containers when going out
Empty Ferraro Rocher plastic containers - use as jewellery
boxes
Newspapers - Unread Sports section used to line the little table
when I have my meals so at the end of it, just throw the newspapers
into the bin, no need to wipe the table and waste water / paper
napkins. 
Disposable containers from frozen TV dinners or from buying
supermart groceries - wash and use as containers for organising
ingredients neatly when cooking. Recently found out that it's
useful for storing dead spider corpses as well. 
Actually, this thread should be expanded to not only include
recycling, but to include the ways we conserve energy at home
too.
I
managed to shave a huge chunk off my winter electricity bill and
I'm very proud of the fact! Hehe!
