Sustainability of NANO-SAKURA

    The word “sustainability”, we recently hear this word often when we discuss about environmental issue.  NANO-SAKURA recognize this word, as controlling resource consumption and its accompanying effect to the environment appropriately.  As a result, we believe that standard of living of human beings can be maintained in a long term.  Therefore, we continue to make an effort to carry out that concept.

What NANO-SAKURA can do to protect environment

1. Reducing the bad environmental impact due to nano cellulose own property.

2. Reducing the bad environmental impact due to improvement of composite functional property.

3. Resin consumption reduction by mixing cellulose into products.

4. Reducing the bad environmental impact by increasing biodegradable resin market demand.

5. Reducing the bad environmental impact by promoting recycling.

6. Reducing the bad environmental impact with nano cellulose original feature compared to glass

    fiber and carbon fiber as reinforced material.

7. Possible material to solve marine microplastic pollution problem

1. Reducing the bad environmental impact due to nano cellulose own property.

Nano cellulose can be made by breaking down cellulose into nano size level and cellulose is one of the main components of plants, woods and trees.  CO2 in the atmosphere is absorbed into plants during growth so that releasing CO2 by utilizing plants will not effect the concentration of CO2 as a whole.  Therefore, nano cellulose is the material with minimum impact to the environment through all the process including manufacturing, processing, usage and disposal stage.  Furthermore, cellulose is biodegradable and will be decomposed into water and CO2 in nature with the help of microorganism.  In nature, plants, trees decomposed into water and CO2.  Because nano cellulose is nano size with larger surface area than normal plants so that It could be suggested that they may decompose easier than plants in nature (this assumption needs to be verified experimentally before come to firm conclusion.  It is only a speculation at this stage.)

2. Reducing the bad environmental impact due to provement of composite functional property.

Raw material consumption can be reduced by improving mechanical strength and durability of molding products itself.  Consumption of transportation energy can be lowered by carrying lighter weight of molding products.  This means that one can save fuel consumption of automotive or airplane.  By improving deformation stability and lowering thermal expansion of molding products, waste of raw material and waste of manufacturing energy, process can be reduced.  As such, Nano Sakura can contribute to minimize the bad environmental effect by improving material property.

*Above resin properties are also for the case not only nano cellulose composite with 100 % nature biomass biodegradable resin but also with petroleum based plastic. 

3. Resin consumption reduction by mixing cellulose into products.

Most of resins are made of petroleum and even some type of biodegradable plastics are made from petroleum.  In this regard, we can reduce the petroleum consumption by mixing with cellulose or with stone type material such as CaCO3 (limestone). 

*Above resin properties are also for the case not only nano cellulose composite with 100 % nature biomass biodegradable resin but also with petroleum based plastic. 

4. Environmental damage reduction by expanding

practical usage of 100 % nature biomass based biodegradable resin.

Our 100 % nature biomass based biodegradable resin can be used as normal petroleum based plastic.  And eventually they will become CO2 and water.  In general, this kind of natural resin is very difficult to manufacture molding products in a mass production level, and also weak.  However, we have improved those weakness with our technology.  So that these kinds of material can be very good for the environment.  NANO SAKURA can contribute to protect the environment by promoting this type of 100 % nature based biodegradable resin materials.

5. Reducing the bad environmental impact by promoting recycling.

This point needs to confirm experimentally before comes to firm conclusion. So that following is only a speculation.  NANO-SAKURA has may have advantage compared to glass fiber and carbon fiber as reinforced material.  Nano cellulose composite material can remake molding products again even after usage while maintaining its strength.  Because glass fiber and carbon fiber are not in nano size, they will break into smaller pieces and become mechanically weaker during manufacturing machine process.  In contrast, nano cellulose is nano size already so that strength may not be effected as glass fiber and carbon fiber do.

*Above resin properties are also for the case not only nano cellulose composite with 100 % nature biomass biodegradable resin but also with petroleum based plastic. 

6. Reducing the bad environmental impact with nano cellulose original feature compared to glass fiber and carbon fiber as reinforced material.

NANO-SAKURA has one clear big advantage compared to glass fiber and carbon fiber as reinforced material.  That is, Nano cellulose is 100 % biodegradable reinforced material.  One can make 100 % biodegradable material with this feature.  Composite material property can be improved by mixing with glass fiber and carbon fiber although these materials are not 100% biodegradable and not good for environment.  This is why NANO-SAKURA can be highly advanced cutting edge material.  At the moment, we are the only one company who can produce this type of material in the world.  With this big feature, Nano Sakura can promote and expand biodegradable resin application. 

7. Efficient utilization of biomass natural recyclable resource such as tree, plant, waste wood, waste paper etc…

We utilize and make composite material with various type of recyclable biomass waste such as waste wood, thinned wood, wood powder, bamboo, rice, cassava waste, bagasse, sugarcane waste, coconut shell etc… We try not to waste any precious biomass resources and use them efficiently for the environment.  This is one of our policy.  The quantity of this kind of biomass waste is huge and discarded everyday in the world.  Sometimes it costs money to discard these type of biomass waste.  Thus, our action can be even economically friendly in some cases. 

8. Possible material to solve marine microplastic pollution problem.

Ultimate goal is to make 100 % biodegradable NANO-SAKURA in the ocean. Plastic pollution caused by development of mankind with petrochemical based chemistry needs to be changed.  Especially marine microplastic pollution problem is very serious problem caused by human beings.  Marine microplastic pollution is destroying the ecology system and nature.  Therefore, it urgently needs to be solved in the world.  Precisely, biodegradable resin has some grades and some biodegradable resin can be decomposed in the soil, but not in the ocean.  The best biodegradable plastic is the one which can decompose in the marine environment.  We, Green Science Alliance is under intensive research to develop such great material.
