Do You Know How Rice Husk Recycled? 

Rice husk has a number of names, the most common being husk, hull, and chaff.

It is the outermost layer of protection encasing a rice grain. It is a yellowish colour and has a convex shape. It is slightly larger than a grain of rice, thus lenghts up to 7mm are possible. Typical dimensions are 4mm by 6mm. It is lightweight, having a ground bulk density of 340kg/m3 to 400kg/m3.
Rice, maize, and wheat are the 3 most cultivated crops in the world, with rice being the most commonly eaten daily foodstuff for more than 2/3rds of the world’s population. 92% of rice is grown in Asia, the majority in Vietnam and Thailand. In 2013 approximately 5.4 million tonnes of raw husk is available from Vietnam alone.

Whole rice husk is a popular bedding for animals. Compared to saw dust it is fire resistant, does not attract insects, and it does not pack/compress meaning a softer bed for animals that does not require as much per m2 as saw dust or other types of bedding. The outstanding feature is that rice husk does not absorb liquid or bind up into clumps; urine and feces run through the husk to the lower level of bedding. This keeps the animals dry and makes cleaning easier and faster. As a soft bedding it prevents hock and leg blisters. It provides insulation and once used/removed it makes a good soil compost.

Rice husk is a waste product that farmers previously struggled to dispose of due to it’s large volume. (It’s volume is about 20% of total rice crop.) Today it is a traded commodity with a growing variety of uses. You may have heard that rice husk is free. It can be. At a rice farm hundreds of kilometers from a port, away from roads and rivers, and up a hill. Anywhere else farmers sell it to millers, and millers have to collect it via truck or more typically barge, transport it to mills, clean and grind it, pack it, transport it to port, and load it. The cost of this (transport & energy) forms the majority of the cost.

Rice husk is low in density and an unusual shape. This poses storage and transport challenges. Hence why it is usually ground and packed in PP bags. Our ENERPAT rice husk baler can help to package it. Pressing the material into dense block and then bag it. This is one of the ways that majority of ENERPAT rice husk recyclers adopted. This baling solution corresponds to a bagging baler.

The uses for rice husk are continually growing. Today it is increasingly used as biomass to fuel and co-fuel power plants. There are now many power plants in Asia powered 100% by ground rice husk. What is more, baling rice husk normally creates a very dusty environment, regardless whether you are using a bagging baler or a briquetting baler. These two products are producted by our company. In order to minimize the amount of dust flying around in your workshop and contaminate your work space, you can consider adding a protective cover at the top of the hopper to help containing the material within the machine.
