Study On The Procedure And Methods Of Compulsory Cleaner Production Audit

Compulsory Cleaner Production Audit (CCPA) initiated by China. Since its inception, it has used voluntary cleaner production audit procedures and methods which introduced from abroad. To some extent, the procedures and methods hindered the further development of compulsory cleaner production audit in China as the different relevant and applicable environment.Through understanding the status of CCPA in China, basing on original audit procedures and methods of CP, using the experience of other countries for reference, this paper proposed its own set way of CCPA procedures and methods.This procedures augmented research on the enterprise which exceeding pollutant discharge criteria or total amountlimit or using of toxic and hazardous materials in production or emissions of toxic and harmful substances and the objective by the CCPA, which determined the audit key point and programs. Meanwhile, in order to ensure audit quality, it increased the part of counterpart funds and supervision of program implementation.Methods researching based on the idea of "where-why-how". For the "where", this paper put forward Production Flaw Identification method innovatively, which find the material and productive process flaws by acknowledging the toxic or harmful material and the destructive factors to produce and environment etc. Throgh one manganese company CCPA's study, Production Flaw Identification method found out 18 flaws in this company.Then by the production factors, this paper applied Root Causes Analysis method to analyse the reasons of flaws and to generate solutions, and it solved the problem of "why" and "how". Utilizing RCA in case CCPA, it found reasons more drastically. At the same time, this paper ordered the flaws in perniciousness by AHP-Fuzzy Comprehensive Evaluation, and the 1-9 flaws are audit focous in this CCPA. Finally, AHP-Fuzzy Comprehensive Evaluation was used to sort the solution. It educed the solutions of Secondary manganese slag leaching and ion exchange wastewater which were the programme that should be implemented in this audit. The overall results were consistent with the actual audit, and it proved that these methods are feasible in CCPA.
