Abstract: This paper summarized the general situation, development present situation both athome and abroad, and its application etc on ecomaterials, there are a overall understand on
new progress in research on ecomaterials.
Keywords: ecomaterials; EIA ( Enviroment Impact Assessment)
Material industry is holding human society's development, has brought the convenienceand the advantage for the humanity, but simultaneously in the material production, processing,
the circulation, the consumption, the use, recycled in the process which and abandoned also tobring the heavy environment burden. This urges the various countries' material researcher tocarefully examine the material from the beginning the environment burden, research materialand environment mutual function, quantitative evaluation material life cycle to environment
influence, research development environment coordinative new material. This has produced
an emerging discipline—ecomaterials.
1. Ecomaterials survey
The ecomaterials is one kind to improve the ecological condition, the government
environmental pollution, the purification and the repair environment material. [1]
1.1 Ecomaterials classification
The ecomaterials includes: environment engineerig material, green packing material,
environment building material, environment degeneration material, environment purificationmaterial, environment repair material, environment substitution material and so on.
1.2 Ecomaterials characteristic
The ecomaterials should have three characteristics: One is the material sophistication;
Two is the ecological environment coordination; Three is material comfortableness.

2. Domestic and foreign ecomaterials present situation
The ecological ecomaterials is in the humanity realized walks to the ecologicalenvironment protection important strategic sense and the various countries under thesustainable development path background to raise in abundance, is domestic and foreign thematerial science and engineering research development inevitable trend.
2.1 Overseas ecomaterials present situation
1991 year Japan first puts forward the ecomaterials concept.Held four ecomaterials
international conference since 1992.The European state, Japan, Canada, country cooperations
and so on US and China has published “the ecomaterials handbook”.[2,3]In 20 year after today, should request explicitly the material science and engineering
worker realize:(1)While satisfies the user as far as possible to material performance requirement, must
consider saves the resources and the energy as far as possible, reduces as far as possible to theenvironment pollution, must change the one-sided pursue performance the viewpoint;(2) When the research, the design, the preparation material as well as the use, abandon
the material product, certainly must material and in the product entire life cycle, to theenvironment coordination took the important appraisal target, the change designs theproduction by all means, after but does not attend to uses and abandons the resources
regeneration use and the environmental pollution viewpoint;(3) This definition development will involve multily-disciplinary overlapping, not only
will be technical overlapping, moreover will have the wider knowledge foundation and astronger practicality, not only will discuss the science and technology benefit, the economicefficiency, but also will have to discuss the social efficiency, the materials science technology
industry concrete development targets and global, the various countries' sustainable
development big goal will unify.
The ecological environment material is precisely raises under such background, is on
1990s international one of material science and engineering development newest tendencies.
This kind of material consumes to the resources and the energy few, to the ecology andthe environmental pollution small, regeneration use rate high or degrades and may circulate
the use, until moreover requests from the material manufacture, the use, to abandon in theregeneration use entire life cycle, all must have with the environment coordinatedcoexistence.[4] Material environment load assessment method (LCA) and standard(ISO14000) establishment. The International Standardization Organization has formulated theenvironment management international standard (the ISO14000 series) the related LCA basic
principle (ISO14040) and the catalog analysis standard (ISO14010).The world environment
database has surpassed 1000. Germany is in the world carries out the environment symbol
most early the country.[5] Recently US promoted one kind newly the anti-chemical protective
suit which made by 100% high density polyethylene, used in to contacts the virulent harmful- 211 -

chemical the impediment protection. This product may recycle completely remakes, also may
burn down processing, does not produce the halogen compound. Has carried on in Japan theglass fiber reinforced plastic material circulates again smashing processing, uses in the roadoil material the strengthening and the modification.[6]2.2 Our country ecomaterials present situation
Our country is a developing nation, along with reform and open policy andmodernization development, environment question also more and more urgent pendulum infront of us. Our country's ecomaterials research may trace on the century 80's intermediatestages, in the agriculture the massive mulching plastic, big awning to plastic use, formation“white pollution”. From this may degrade the plastic to the environmental protection theresearch development, is our country studies the ecomaterials the start.
Ecomaterials statement to our country steel and iron material development influence.(1)automobile uses the steel high strength; (2) special-purpose steel alloy new series; (3) basedon regenerative cycle steel products ecomaterials study design concept.[7]On the other day, an item for the first time settled down Nanjing University in thedomestic development new ecomaterials and the renewable energy research, and has had theimportant gradualness research results in under the school support and the investment.
3. Ecomaterials development and application
The natural material development. Looking from the ecology viewpoint that, the natural
material processing energy consumption is low, circulates renewably the use, easy to process,carries on the high added value development to the natural material, the obtained material has
the advanced environment coordination performance and has the fine operationalperformance.
Recycle material design and development. Recycle metal material, if carbon steel
anticorrosion coating material when recycling does not have to consider the coating theseparation, causes the steel and iron to recycle the alloy environment burden to be smaller.
The ecomaterials research already penetrated into industry each domain.In the resources andthe energy effective use, reduces in the environment load the ecomaterials to have the very
big superiority, realizes a material industry sustainable development important development
direction.
The ecological ecomaterials is 1990s a new domain which forms in the international
high-tech new material research, its research development in Japan, America, Germany and soon the developed country is extremely active. The main research direction is: (1) faces
directly with the environment question correlation material technology, for example, thebiology may degrade the material technology, the CO2 gas solidification technology, SOx, theNOx catalysis transformation technology, the waste again converting into resources
technology, the environmental pollution repair technology, in the material preparation- 212 -PARTⅣ BIOMASS DEGRADATION
processing pure technology as well as saves the resources, the economical energy technology;(2) development can cause the economical sustainable development the environment
coordinative material, like biomimetic material, environmental protection material, fleon,asbestos and so on deleterious substance substitution material, green new material and so on;(3) material environment coordination appraisal.
Our country also has carried on the massive work in recent years to the ecologicalecomaterials research, also has obtained certain result.If from bakes the anode to thealuminum industry in and bakes the anode in advance the LCA appraisal, for from baked theanode craft the improvement provide the scientific basis.[8]4. Conclusion
The ecomaterials is one of material science and engineering most recent development
tendencies.How the ecomaterials study main research reduces in the material processing andthe use process to the environment destruction; Establishment quota appraisal material
environment burden ecological cycle appraisal method (LCA); The environment load takes asinspection material the new target, uses in instructing the development to have theenvironmental awareness green material and the product; discipline knowledge and so on
resources efficiency, ecological equilibrium, environmental protection, sustainable
development integrate the materials science, protects the nature, benefits the humanity.As the
21st century advanced materials, the ecomaterials the collection material sustainable
development, the resources regeneration use, front science and the technology and so on clean
production in a body, makes to the national economy development the important contribution.
