regarding point 2 (economical use of resources), we proposed printing a single piece that might be used as business cards, letter paper and cd/dvd envelopes.
an a2 sheet of paper is printed in high grammature to generate 55 business cards, but the same sheet in low grammature is cut into 4 sheets of letter paper.
the black logos become the headlines in the letter papers, and the text is printed over the yellow logos.
the letter paper has a specific way to be folded in order to be used as an cd/dvd.
