Research On Analysis And Evaluation Method Of Green Manufacturing Techniques

Green Manufacturing (GM) is the key approach of manufacturing sustainable development and main technology of Cleaner Production and energy-saving and emission-reduction on manufacturing. The Green Manufacturing implementation and operation are unable to do without Green Manufacturing Evaluation (GME). Only through scientific, logical, correct GMA, Green Manufacturing Technologies (GMT) can be developed to realize the optimization of technique and economy and environment, to arouse enterprises interest. In this way, Green Manufacturing Technologies can be apply and promote in enterprises.At present, GMA is still in the primary development stage, some researcher have done some evaluation to GMT, which is the one stage in production life cycle. And there has no systematic GMA method. LCA is the relatively applicable assessment method to GMA, but it has some limitations and not been popularize and apply. Because of these problems and the importance of GMA, the systematic research on GMA method and technology are of great significance.Firstly, based on the Green Manufacturing technology system and frame, the Green Manufacturing Evaluation system and frame is proposed, it includes general objectives, partial objectives, impact factors, assessment objects, assessment methods, etc. And everyone of them are discussed in detail.And on the basis, combined with the technical green characteristics, the assessment indicator system of green grade for GMT is put forward, which is for every stage in life cycle. And it discusses the impact factors of every indicator.Aims at the current situation of having difficulties in life cycle assessment method implementation and popularization in China, this paper analyzes the several difficulties, and puts forward the Simplified Life Cycle Assessment(SLCA) with that. It elaborates the technical principles of SLCA from several main aspects. And especially for the difficulty of data deficiency in China, it raises three ways to obtain data, which takes benefits of Green Manufacturing Evaluation Technology implementation and application.Then, based on the SLCA method, and build on environment impact assessment (EIA) and healthy risk assessment and other synthetical evaluation methods, this paper puts forward assessment moulds for Green Manufacturing Technology in different stage. Studies has shown that green products assessment and green design assessment should take product system as study object and take all life cycle of product as assessment scope, and adopts appropriate synthetical evaluation method. And the Green Manufacturing Technologies in other stage should take technology as study object and single stage as scope.On the basis of assessment indicator system and assessment mould, this paper discusses the implementation of Green Manufacturing Evaluation Technology and the select principle of assessment methods and basic steps of assessment, and studies the key techniques and methods of assessment process. It designs a prototype system for Green Manufacturing Evaluation, analysises it's overall structure and design proposal of functional moudle in detail, and illustrates the partial functions that have been developed.Finally, the Green Manufacturing Evaluation Technology and method are applied in the process of alumina, the results shows the assessment mould can reflect the techniques merit, and take benefits of the improvement of techniques.
