Hi,
I am a student of Chemical Engineering. I've almost completed my graduation. Now I want to start a small business of manufacturing home made recycle paper. I need information about its demand and what equipments are very much essential for making home made paper. Is it possible to make white color paper ? Will anyone can explain me the steps of making smooth home made paper, please.

Sorry to rant, but - as an almost graduate Chemical Engineer - aren't you supposed to know where to look for such information?

I used to do work experience over the summer holidays in a paper mill.  (we actually made massive rolls of tisse, but the principles are the same)

For white paper, you need to bleach your pulp (and possibly add a little TiO2 for bright white, or atandard white dyes).  For other colours - use dyes.

Making the pulp should be easy - it is then watered right down and passed through mesh untill the appropriate thickness is aquired.     For smooth paper - I would assume that you would need a finer particle size in your pulp (filter the diluted pulp?).   Hardest part will be getting a smooth even layer on the mesh - practice should get you there.   I think some may add a little binder to the pulp/dye/water mix to make the paper stronger.

I think I might try it too sometime.

No it will need some bleech, some white pigment/filler some optical brightening agents and possibly some shading dye.

It is not possible to make white paper with bleech alone. 
If you try it you'll get a dull pale yellow/grey colour.

Just about all commcerial white paper uses optical brightening agents to give the bright white colour.
