Pollution Diagnosis And Cleaner Production Audit Methods And Evaluation Index System

Research objectives

Investigation and measurement of energy consumption, water consumption, raw and auxiliary materials consumption, pollutant production and solid waste recycling status in leather making enterprises were conducted. Quantitative analysis of material utilization status and types and direction of pollutants was made. Measures and methods for improvement were put forward to form a cleaner production audit method and evaluation index system suitable for China's leather industry.

Task requirement analysis

To guide the optimization of the existing technology, and to provide the basis for the implementation of reclaimed water reuse technology, the design of green industrial chain and the optimization of clean technology in leather making process.

To promote the implementation of relevant laws and regulations in leather industry, and promote the clean production of leather and the implementation of technology.

Related technologies at home and abroad

The ISO standard has been used to clean the leather industry in foreign countries, but there are deficiencies in pertinence, suitability and index system.

There is no standard auditing method and evaluation index system for leather industry at home and abroad.
