3R Concept Reuse,recycle and repair

Hi there,
Do you agree that by adopting 3R concept we can keep the world more healthier
for more longer time and furthermore can create new business and generate income
to you.
I 'm thinking of generating recycle, reuse and repair for books if possible from the
whole of the world. The idea came in when I see my university text still in the bookshelf
for more that 10 years after the graduation without been opened.
If all of these books can be use by others student, we can sell it with minimum cost and
we can buy or share others book with members.
