To create a future vibrant waste economy which increases the sector’s contribution to GDP and job creation it is necessary for the dtic to become involved in a sector which has traditionally been the purview of environmentalists and waste management experts in DEFF and technology and innovation scientists at the DSI and the CSIR. [...] The attraction of general industrial waste and tyres is that they are available in large and usually predictable quantities, security of supply is high, ownership is clear and the quality of the waste is good and relatively reliable. [...] As explained, a homogenised raw meal of inputs is heated in the manufacturing of cement and the composition of this raw meal is carefully controlled as it determines the chemical composition of the final cement product produced and hence its performance characteristics and quality. [...] Third, and crucially, control of the waste treatment process is critical to the quality and regularity of the product produced as an output of the co-processing facility. [...] The CSI note that the quality of the dialogue between the operator of the co-processing facility and the cement company as the final user of the processed waste is one of the most important keys to the success of such a facility.
