BrionesIndustrial Technology Development InstituteDOST, Bicutan, Taguig, Metro Manila, PhilippinesEmail: bel@pacific.net.phBy virtue of Executive Order No. 128 dated 30 January 1987, the National Science andTechnology Authority (NSTA) was reorganized into the Department of Science and Technology(DOST). Under this reorganization, the Materials Science Research Institute (MSRI) was mergedwith the National Institute of Science and Technology (NIST) and was renamed IndustrialTechnology Development Institute (ITDI). The ITDI remained to be one of the Research andDevelopment Institutes (RDIs) of the DOST.ITDI is mandated to conduct research and development (R&D) of technologies usingindigenous raw materials of the country for adaptation and possible commercialization in the areasof chemicals and minerals, food processing, electronics and process control, fuels and energy,environmental, material science, and microbiology and genetics. Alongside the development oftechnologies, ITDI is also mandated to render a wide range of technical services for various sectorsof the local industry.AccomplishmentsOne of the research areas that ITDI is undertaking is the utilization of seaweeds and its derivativefor various industrial applications. A total of 22 research projects (List 1) were completed rangingfrom process modifications, purification techniques and pharmaceutical applications of marinehydrocolloids. Among the completed projects, the production of hard and soft capsules fromcarrageenan is the most significant (Fig. 1). It garnered awards and recognition in 1998. Theproject won 3rd prize in the 8th Scientific Poster Exhibit of Health and Related Technologies,Professional Category sponsored by Philippine Council for Health and Related Technologies(PCHRT) given on July 15, 1998. It also bagged the 1st prize award for the Most OutstandingCreative Research (LIKHA Award) in the National Inventors' Week, given on November 23,1998. At present, the project is being undertaken in collaboration with Shemberg MarketingCorporation and Drugmakers Laboratories, Inc. for the commercialization studies.Figure 1. Carrageenan capsulesProceedings of the National Seaweed Planning Workshop The on-going projects for this year is focused in the utilization of carrageenan forpharmaceutical products (List 2). The development of absorbable sutures from carrageenan (Fig.2) obtained the 1st prize award for the 12th Scientific Poster Exhibit of Health and RelatedTechnologies, Professional Category sponsored by PCHRT given on July 20, 2001.Figure 2. Carrageenan absorbable suturesFor the next three years, ITDI has lined-up several projects for the utilization of carrageenan(List 3). Aside from the regular research projects that are being undertaken, ITDI rendered technicalservices like contract researches and technology transfer like lecture-demo/training on seaweedprocessing to would be entrepreneurs. These include the production of gulaman bars, agar, semi-refined and refined carrageenan. List 4 shows the completed contract projects from 1988- 2000including technical assistance extended to small medium enterprises.Aside from the local funding that ITDI received from the Philippine Government, other foreignresources are being tapped. A number of proposed projects (List 5) were submitted to variousinstitutions abroad for funding.ITDI's vision is to be a "world-class S&T Institute with a social conscience, generating andtransferring effective and efficient technologies, and providing quality and reliable services toindustry and country, for the upliftment of the quality of life of the Filipino people".List 1.
