As listed in Table 14.1, various other waste streams can be incorporated in Ceramicrete to produce useful ceramic matrix composites. In addition to those listed in the table, Wagh and his group have explored incorporating drill cuttings from oil fields, slags from iron industry, wood chips, saw dust, and many other waste streams [8]. Most of these studies were limited to proof of concept, and more work is needed to demonstrate concept usefulness. Here, we discuss case studies on swarfs and red mud in which detailed work has been done.

CBPC matrix composites can incorporate a high volume of industrial waste streams such as fly ash, mineral waste such as iron taUings and Bayer process residue from the aluminum industry (red mud), machining swarfs from the automobile industry, and forest product waste such as saw dust and wood chips. Table 14.1 lists some of these waste streams and potential products or applications. 

As an example we explain prices of roundwood, timber, wood chips (for wood pulp), and saw dust. An average price of roundwood is about 84/m (about 7/GJ). Market prices of timber and wood chips for wood pulp are about 45,000 yen/m (about S31/GJ ) and about 8,000 yen/m (about 5/GJ), respectively. A market price of sawdust for fuel or manure is about 1,000 yen /m (about S0.7/GJ) [6. The wood prices for non-energy are higher the wood price for energy. 

Most amino and phenolic thermosets are used in the production of composites, mainly prepared with wood (wood-plastic composites, WPC) [68]. Particleboard, or the chipboard is a kind of WPC, which is produced from wood particles, such as wood chips or saw dusts, through their glueing together with synthetic resins or other suitable binders, by pressing and extruding afterwards. In most particleboards, the resin used is formaldehyde-based. 

Wood-derived products (chips, shavings and saw dust) or- cellulosic fibers (- flax, - sisal, - jute, - hemp, coir (- coconut), - chinagrass, - straw) are sometimes added as extenders and reinforcing materials to cements and mortar in constmction itself or in preformed bricks and boards. The necessity to substitute asbestos has...
