Hi Audiences,

Please give me your sincere comments on this video  =


http://greenation.ning.com/video/build-green-with-rice-husk


because this is a zero budget production, and I am trying to improve on it.

some negative comments or positive comments will suit me fine.

It is not an advert, but a awareness campaign on the use of :
rice husk waste converting into building material

thanks for watching

There are many recycled products out in the market, and when people are doing recycling, they tend to downgrade the value of the product... e.g. from clear paper recycled to toilet paper. etc

But we are different, we dont recycle material, we use waste material and transform it into high value products... waste material is 0 dollar in costing... and we transform it into something of value by 100 times.

       thanks  for the article Francis,


       - technically : the fiber  is unique, need chemistry(carbon) to analyze the contents

       - economic approach: in  Asia  this been using for burn/bake the bricks/earthen ware

         very scarce to get it, every rice milling already been booked/blocked by the user.

         (mostly the bricks burner/maker)

       - sensitiveness: need analyze about its resistant against  wet environ (water).

       - biological: never found it could be contaminated by fungus/musk  in wet spot.

         and  still many  few others  comparative  things to over view/research


       hope  it would bring some interest   ..to keep on

From DIY house

We are getting the rice husk very easily in Malaysia.( South east Asia)

Its moisture retention is 0.3% compared to convetional wood : 10% moisture.

and compared to wood plastic composite : 4%


Anyway, We have already used rice husk to build houses, eco resort, hotels decking, shopping mall decking in our region...


In terms of technical strength comparison, it doesn't fare better than teak, but it is better than most other hardwood.   can be used 100% for house building.

Dear Mr. Francis Teo


I watched your Ytube presentation and your web site the products are relay Green and i would like to know more about the product pl reply to my mail id so i can be in touch.

      Dear Francis,


      by  economics aspect: 

      the rice husk may be cheap and abundance,  but talking to be a building materials, let say

      boards,  it need  some certain glue (adhesive) and  the press machine & others

      till it comes to a medium density  or even  the hardboard.  last but not the least the power-

      cost(energy) for producing it into Industry scale and economics (commercial) figure

      numbers.

      If said so that the fiber and the hardness retention  are more  than  common hardwood,

      it  would  be the chalange to replace  wooden pulp to producing  MDF board.

      Germex please  come in and  conjunct with your topic of  :

I dont think I want to go into dispute with Germax... over this material..

As for photos, those guys who saw the youtube video will already have seen what is it all about.


As for technical speciaification.

Comparison with Teak wood, rice husk timber is simply a new type of material that is meant to target the middle range market... while teak is for high end market.

From DIY house

In terms of application, it is best used for outdoor application, since it is waterproof, and it is strong enough for carry the weight of 32 person over a 1 meter length deck and

hold the structure without breaking between two joint 0.5 meter apart.

comparison with conventional wood, a deck need to be supported every 15 inch to 20 inch.

while Rice husk timber needed to be supported every 24 inch...

comparison with conventional wood, most wood will rot in the outdoor condition except teak and some super hard wood like ip wood.  while rice husk timber will not rot, and will not change shape.

I think that is all we need to talk about. cos the rest is up to the reader own eyes... maybe

they will like to visit the factory when the factory is in flood condition...

cos the entire factory office is made from rice husk timber.  withstand more than 5 floods. such for experimentation its endurance.

Rice husks are indeed interesting as an insulation, but the technology involved and the uses for the material are totally different. Due to its protein contents, straw can readily be compressed into boards, while rice husks only make sense as a lose infill.

Ah Guys, maybe we are seeing a technology breakthrough, cos in the past , straw is the best solution for compression into board.  but with some tech breakthrough we are seeing rice husk being more suitable for board making.


We are talking about MDF not composite... MDF is compressed with bonding agent.

One can google rice husk particle board or rice husk timber to find out more

Cos rice husk is already in the market made into MDF in INDIA, Malaysia in large quantity.....

Indians are already using Rice Husk to made MDF board for light weight wall panelling in numerous cities in INDIA. while in Malaysia they are using rice husk MDF for furniture making and sound proofing.. 

with the abundant rice husk waste ... no wonder the indians are using it to replace timber, since INDIA government ban the cutting of timber.

and pple are using rice husk to create thick boards that can be used for furniture making.

Malaysia government also ban the chopping of timber recently in West malaysia, and only allowed those few monopolies to do logging in east malaysia.  Loggers are definitely looking for new logging paradise...

and therefore there is the rise of such waste material being used to replace timber.

Aerogel is almost a product out of science fiction.

Nicknamed “frozen smoke,” aerogel is extremely lightweight material, with a density only 3 times that of air. Only a small fraction of a volume of aerogel is the material itself. Most of the volume is filled with air. This makes aerogel an excellent insulator. (Aerogel provides nearly 40 times the insulation of fiberglass insulation.)

Aerogel can withstand great pressures and is also an excellent sound insulator. Aerogels can also be used to absorb airborne pollutants and have been used to clean up oil spills. NASA also used a section of aerogel as part of its Stardust probe to collect samples of material from the tail of a comet.

Aerogel is available for some high-performance applications, but due to its high cost, it has not been widely used. However, new research from a Malaysian scientist offers the potential to drastically reduce the cost of producing aerogel, and could lead to new possibilities for its use as a building and insulation material.

The New research is developed using rice husk, and becos rice husk has 20% silicate content, it provides the ingredient for building of new generation building material that is highly insulated. and is currently being commercially used for the creation of this Aerogel.


Rice husks evidently have a high silica content, and silica is the main constituent of aerogel. In addition to potentially being able to produce aerogel for one-fifth the current cost, this also addresses a problem with disposing of rice husk waste.

Because aerogel is translucent, rather than completely transparent, one of the places it has first been used in architectural applications has been in daylighting panels. Commercial applications of aerogel are from companies such as Kalwall and Advanced Glazings, both of which produce diffuse lighting windows that incorporate aerogel to produce panels that transmit light while having an insulation R-value equal or better than that in an insulated wall in a new home. These windows aren’t for vision, but they allow a high percentage of light to be transmitted, allowing for diffused daylighting, which is a better method for lighting without producing unnecessary glare. However, until now, these windows have been used only in special instances because of their high cost.

If prices for aerogel become significantly lower, it should be possible to see highly insulating panels that can replace traditional forms of insulation. Even more compelling is the possibility for retrofitting existing buildings with relatively thin panels that can significantly improve their thermal performance. Since buildings last for such a long period of time, retrofit solutions are going to become an important part of reducing the amount of energy used by buildings without needing to demolish and replace everything that has already been built.

The product looks great.  As for the video;  I would shorten it.  No one wants to listen to music for a long time while waiting to see what the product is.  Start with the beautiful products that can be made with rice husk and move on from there.  The video does not seem to market the product well.  You will want to address some of the concerns outlined here in the video also.

Just my opinion. 

I would really be interested in learning more about this product and its availability and suitability in the US.

Ken

thank you for your comments... this is my first attempt to do a video... therefore asking for alibaba audience opinion...
It is important to receive opinions from the ground level.

thanks
