Rusk husk is the shell of the rice grain, which is a byproduct of rice milling. These days, rice husk can be used to produce a range of products. Such products include food containers, plates, bowls, lunch boxes, cutlery, clothing hangers, and more.
In this guide, we explain the basics of using risk husk materials and list Chinese manufacturers producing risk husk products.

What is rice husk?
Rice husk is the shell of the rice grain, which is usually peeled off during the rice milling process and dumped afterward. The constitution of the rice husk is typically 50% cellulose, 25%–30% lignin, 15%–20% silica, and 10%–15% moisture.
Small power plants have been using rice husks as biofuel for brick production, generating heat, steam to power rice dryers and rice mills for a long time.
In recent years, rice husk has been repurposed by some manufacturers as the raw material for both biodegradable and more eco-friendly plastic composite products, mainly as foodstuff containers, food packaging, and tableware.
Below we list two of the main benefits of rice husk when used to manufacture consumer products.
Easy accessibility, high yield, cost-effectiveness
Around 0.28 kg of rice husk is peeled off from each kilogram of milled white rice. Therefore the economic benefits and eco-property of rice husks have been studied for their potential to be used as a material in consumer products.
Rice husk is composed of cellulose, lignin, lipids, proteins, silica, moisture, water, and other compounds, which allows manufacturing products that are water-resistant, and low thermal conductive.
Is there rice husk plastic composites?
Yes, composite materials are constituted of two or more materials that are of relatively dissimilar properties, such as rice husk and polypropylene, polyethylene, or other plastics and coating agents. The goal is to create a final product that is more eco-sustainable – as it uses a lower amount of plastics – and might even have better performance than the original materials.
For example, by being lighter than a product entirely made in polyethylene, and more durable than a product entirely made by pressed rice husk.
Note that the chemicals are usually added to bond the rice husks and reinforce the sturdiness of the products, but also to make the product more flexible, and durable. At the moment, most factories use a mix of 50% rice husk, and 50% plastics.
That said, plastic composites are not biodegradable.
What kind of products can be made of rice husk?
In this section, we introduce some of the most common categories of products that can be manufactured using rice husk.
Some manufacturers claim that their products are 100% biodegradable or household-compostable because these products are purely made with rice husks and not mixed with plastics to create a composite. This is possible because the cellulose and lignin in rice husks provide a sturdy texture to the products.
A large part of the products that contain rice husk, however, also contains resins and other chemicals to enhance the product performance, such as resistance, flexibility, and durability. In this case, the products aren’t biodegradable.
General consumer products
Although at the moment most of the suppliers that specialize in rice husk products mainly offer food contact products, given its properties, rice husk can also be used to manufacture other consumer products such as:
The cellulose component of rice husk and rice straw make them ideal materials to build fiberboards for construction purposes. Typically, shredded rice husks are mixed with resins before going through other production processes such as hydraulic press and drying until the fiberboards are made.
The fiberboards that can be made of rice husk composite includes:
Medium-density fiberboard (MDF)
High-density fiberboard (HDF)
Can rice husk be molded?
Yes, rice husk can be mixed with several plastic materials and processed via compression molding, injection molding, or extrusion techniques in order to create a diversity of products.
Here some of the most common plastics that are used in rice husk composites:
Low-density polyethylene (LDPE)
High-density polyethylene (HDPE)
Polylactic acid (PLA)
Polyvinyl chloride (PVC)
