Philippines develops socio-economical and environment-friendly technologies

As announced by the Department of Science and Technology (DOST), the technologies they developed make use of local raw materials thereby making it more socio-economical and environment-friendly.

What sets the technologies developed by the DOST apart from their commercial counterparts is their use of local raw materials that went through improvements in terms of product or process.

The Chief of the Technical Services Division of the DOST-Industrial Technology Development Institute (DOST - ITDI) Ms Nelia Florendo shared, “These government-developed technologies are designed to factor in the social, economic, and environmental benefits.”  

DOST-ITDI has been leading in the development of technologies that are both useful for enterprises as well as the environment.

Because the locally-sourced raw materials they use are already available in the country, local technologies do not need to import materials. Therefore, they have lower costs than their competitors.   Nearly a hundred industries expressed interest to adopt and collaborate with the institute on their technologies during their recent technology offering forums. Different technologies such as food technologies, food processing technologies, health and wellness, green engineering, and advanced technology were presented. These technologies were readily available for transfer or licensing to interested parties during the forum.

DOST Undersecretary Ms Rowena Cristina L. Guevara made a request from the participants saying, “We need the help of the people from the industry so that every Juan and Juana will make use and benefit from the technologies we have developed.”

Ms Guevara narrated that there were clients who wanted to avail of their technologies but were not yet ready to take them on and so the regional offices and facilities of DOST will be assisting them as they improve their facilities and production processes.

 In the last five years, more businesses and local government units in Zamboanga, Butuan, Negros, Batangas, Camarines, Quezon, Ilocos, and even in Metro Manila area (Parañaque and Navotas), among others, have used DOST-ITDI technologies, especially in their livelihood and environmental programs. R&D teams and their public and industry stakeholders were given the opportunity to showcase and learn from each other during the technology offering series of DOST-ITDI.

DOST-ITDI completed 152 research and development projects in the last five years alone. These projects have dealt with chemicals and energy, environmental and biotechnology, foods, materials science, and packaging.

OL-Trap, vinegar acetator kit, bioreactor, styro/plastic densifier, and ceramic water filter are some of the projects that have already been adopted.

The OL-Trap is used to address the national concern of dengue. The simple contraption consists of a black plastic can. The solution (pellets dissolved in tap water) is introduced into this can and by capillary action, moistens the board. The moist makes it ideal for the dengue-carrying mosquito to lay its eggs on.  This type of mosquito is normally attracted to black. These eggs will no longer develop into adults, thereby stopping its proliferation.

The acetator vinegar production was designed to accelerate the tradition fermentation process of producing vinegar. It can convert most sugary materials to vinegar. These materials are coconut water, pineapple wastes, sugar cane and dried mango spent syrups.

The bioreactor is a high-temperature reactor-based composting technology that accelerates the biodegradation of municipal solid wastes for its rapid stabilisation.

The styro/plastic densifier technology involves conversion of post-consumer waste polystyrene, commonly known as styropor, packaging materials into rigid functional products. The densifier works on the principle of an oven having gadgets that control temperature and smoke emission.  The melted material is then poured into mouldings for varied products like pots/planters, cat-walks tiles, simulated lumber/wall tiles, and table/armchair tops.

The ceramic water filter is a simple system of water purification with the initial use of coagulants/flocculants as a pre-treatment for water (deep wells and other sources).  Then, it is followed by filtration through layers of sand filters and disinfection by chlorination to eliminate waterborne microorganisms.  It is culminated with the filtration by using ITDI-developed ceramic filters, which are very effective in trapping any suspended particles.

DOST-ITDI also offers technical assistance to the Filipino industries, providing them with packaging research and development. They have also contributed to process improvement, cleaner production, plant layout, test and analysis, waste treatment, and many other technical services which have resulted in increased production volume and productivity.
