Because there are variables beyond my control (clays, papers, water, mixing errors and etc) always pre test fire what you have before a big project. No guarantee can be offered that 'alternative" commercial paperclays now on the market will meet the all the performance advantages of my high performance trademark P'Clay® brand only available from licensed manufacturers/distributors.

Industrial Waste Minerals and Pulp Recycling Multigeneration Paper
Problem in Brief:
At best, sludge from recycled papers that are loaded with ink, and/or scrap glazes or clays sit in piles in back rooms warehouses awaiting proper disposal. At worst we know there are violations of even this common sense practice. These sort of wastes if just disposed on a landfill could leach out into watersheds.
Paperclay ceramic is versatile. It can be compounded to be either a porous or vitreous ceramic.( US Pat. No. 5,726,111) It can be molded and formed by a variety of methods in any shape. Parts can be assembled in ways not possible with traditional ceramics. The industrial manufacture process can be streamlined as a result. It has properties of high thermal and refractory tolerance.
Porous types can be used for filtration of any fliud or gas such as industrial exhaust etc and other special applications. My animated hypothesis vision is seen Inside Paperclay on UTube (see link to left) or special compounds will result in a porous ceramic that will change the fluid poured through as desired. Porous fom can be also an absorbent or cleanup medium.
Vitreous types of paperclay ceramic can be compounded and fired to a rock like ceramic that is watertight. Harmful mineral wastes can be rendered inert or enclosed in it.
Mix waste materials like these up in a controlled sequence then fire them into stone. Forms for building material, brick or pavement are of course a natural starting point.
Cellulose fiber lends benefit to these mixtures of reclaim just the same way way it does for normal clay and mineral raw materials fresh from the mine. The ink on the paper will burn or melt into the ceramic. The trace minerals or nano and colloidal minerals also .
Scrap glaze sludge mixed with recycled paper pulp has been successfully fired in the lab. The first test result was a gray colored hard tile with less than 0.01% water absorption (i.e. watertight).... with potential use as a durable building material transformed from these so called "toxic" wastes.
Thanks to support of Sonoma Tile (CA) Jon Willilams and I collaborated on early stage research on reclaim and recycling industrial ceramic and paper waste in 1997-1998.
I have been advocating research since I began public teaching on this subject in 1991. Below is a page from 2003 edition.
