"FOREWORD

Rice hull is considered the most ‘unwanted’ rice by-product by majority of the rice millers and some farmers throughout the regions. Rice hull disposal has become a problem especially to millers who dump and burn these along roadsides, much as the smoke pesters the motorists, commuters, and the community dwellers.

Now, rice hull can be carbonized to become an extra source of income.Our biomass experts here at Phil Rice perfected the process and were able to develop a low-cost equipment for rice hull carbonization. They now train interested individuals and farmer-groups in making quality carbonized rice hull(CRH) not just for local use, but also for export. The first recorded export of CRH to Japan was made by Organic Farmers Unit Association, Inc. (OFUAI) of Balbalungao, Lupao, Nueva Ecija. This venture gave them a gross income of PhP45,000 in a month! This was made possible through the technical expertiseof PhilRice, the assistance of our NGO-partner, the Philippine Rural ReconstructionMovement (PRRM), and a private company, AIM Trading Corporation, asthe main exporter of quality CRH.Farmers- turned-entrepreneurs in rice-based production ecosystemsespecially in San Pablo City, Laguna and in Talavera, Lupao, and San Jose City,Nueva Ecija are also producing CRH. To date, five peoples’ organizations(POs) under the PRRM-Kalikasan began exporting CRH to Japan. Also, an Automated Carbonization System (ACS) developed from Japan has been adopted by Oliver Enterprises owned by Nestor Vendivil of Bakal II, Talavera,Nueva Ecija, with the technical support of PhilRice’s Waste Management Committee.

We encourage more farmers and other enterprising groups to try this very promising venture. Thus, we came up with this bulletin that presents the outstanding features of the CRH including the procedure and economic analysis of CRH production. The procedure on how to make a simple open-type carbonizer out of locally available materials at minimum cost is also appended for easy reference. With this technology bulletin, we hope to add more value on rice, and consequently, help rice-based communities to become more productive.Read on and learn how to turn a waste into cash."
