The problem
There are some potential environmental and safety problems emerging during the coprocessing of hazardous wastes in cement kiln because the quantity of hazardous waste coprocessed continues to increase and has exceeded past predictions. In the last year, the times of waring of exhaust emissions were far more than last three years. Meanwhile, the performance of cement changed heavily. These problems would cause serious consequences, if no effective measures were carried out(Aubert.J.E, Husson.B, & Sarramone.N, 2006;Aubert.J.E, Husson.B,
& Sarramone.N, 2007;Conesa. J.A, Galvez.A.,Mateos,F.,Gullon.I.M., & Font.R, 2008;
Karstensen, 2008;Lin,Y.M.,Zhou.S.,Li,F.Z., & Lin, Y.X., 2012). What is more, the quantity of hazardous waste that needs to be co-processed is projected to rise by 20% and 30% in next two years respectively.
Causes of the problem
Through a careful investigation in last three months, the causes of these problems have been discovered. The main reason is the waste contained chemical elements that belonged to other waste and went unnoticed. Among the these wastes, there were some unidentified ones mixed in; some identified wastes were mixed into other kind of wastes by carelessness. Both mixtures increase the uncertainty which contributes to exhaust emissions beyond the safe limitation and low performance of cement. The mixture, however, is hard to avoid because there are serval possibilities. Making sure the quantity of chemical elements which can heavily influence emission and quality not beyond limitation is an economic choice. That needs to monitor the chemical elements of waste instantly during the co-processing.

Details of the solution
Increasing the frequency of hazardous waste testing is the reasonable choice. That means we need to acquire a new method to test the elements of waste quickly and cheaply due to the fact that the
