You have probably seen or eaten rice before but do you know about rice husk or what happens after removal?

Plant biomass like rice husk, coconut coir, and bagasse, etc. are used to make eco-friendly cutlery, tableware, and packaging products.

Rice is not only a delicious source of carbohydrates but it has helped in creating cool eco-friendly products. And, the cutlery you used at the eat-out yesterday may be one!

Natural fibers from agricultural waste like rice husk are finding their way into the silicone industry.

This is because of its many advantages such as being eco-friendly, low cost, and lightweight.

Rice is the staple food for over half of the world’s population because it provides 20% of the world’s dietary energy supply.

Rice husk is the natural hard protecting sheath that forms around rice grains and is a by-product of rice milling.

It’s a major agricultural waste in rice production and it contains 30-50% organic carbon.

Because of their tough structure and size, rice husks have few uses.

We use rice husk for food packaging, drinks packaging, and homeware.

Rice husk used to be seen as a waste product and it was either burned or dumped in landfills, so there are very few companies that make packages from it.

In the agriculture sector, a small quantity of rice husk is used for the manufacturing of fertilizer, bedding, and for the stabilization of soils.

Rice husk is affordable and eco-friendly, but it still has some disadvantages for its usage in the silicone industry.

For example, products made from rice husks like cups and cutlery are more expensive than the ones made from plastic.

When used to make biodegradable plastics, greenhouse gases is released which is very toxic to the environment.

And, this last factor may hinder the market growth.

But, if properly utilized, rice hull will play a great role in many sectors.

And, recycling is the best way to dispose of this strong and durable farm waste produce.
