Waste Reduction in Ceramic Industry

as I'm a ceramic engg. basically, for me it's a challenging job to reduce the waste of my company. I do work in a company pioneering ceramic fiber manufacturing in a wide range of variety. I want to reutilize the sanding waste made in vacuum forming through making thermocoupler sleeve. We work mostly with alumina, silica & zirconia (as raw materials). So, technically I'm very much interested to know the latest manufacturing technology (is there is any better option than vacuum forming). I want to achieve 1500oc temp. resistance.the shape of the sleeve is approximately cylindrical in shape. It will be also very useful for me to know the most useful binder,fining agent/flocculant & neutraliser to be used. I welcome all of the technologists for an open discussion.
