You might learn something from studio photography here. To avoid shading or shadows falling on to a seamless white backdrop, it is usually specially lit with diffuse lighting. So if you can set up a couple of diffuse light sources, pointing at the background, it might help.

For example, I'm sure you get the general idea

Make a extruded background that looks like this:



It emulates the way photoshoots do it. Alternatively if you want evenmore controll give this background a matte shader thatway it will only catch shadows from objects and reflections, so you can comp it on a differentbackgroud if need be.

Quick and dirty solution: just use a really large studio setup.

In your teapot image there's a gradient because that's where the ground "bends" into a wall, so you see shadows where the (spot) light ends. If you use a larger setup where the curve is further away from your object and you use an infinite light source you probably won't have that gradient.

You can probably also use photoshop / alpha channels / separate render for shadow, object and reflections to make the background smooth.
