Radiation-processed plastic waste now used as construction materials
From trash to tiles. Who would have thought that the eye sores commonly found in every Filipino home can now be used to build houses and buildings too? Indeed, through the use of radiation technology, trash such as plastic packaging and containers can now be modified, and made durable to become tiles and bricks that can efficiently make homes and buildings stronger and also more attractive.
This is made possible through project called Post-radiation Reactive Extrusion of Plastic Wastes (PREx Plastic), led by the Philippine Nuclear Research Institute of the Department of Science and technology (DOST-PNRI).
To demonstrate the strength and effectiveness of the radiation-processed plastics turned into tiles and bricks, the PNRI and its partner, the Davao City-based Envirotech Waste Recycling Incorporated, built the “PREx Prototype House.” A prototype of a common residential house that uses PREx plastic for tiles and walls, the PREx House will be the testing site of how the said plastics will maintain strength and durability in the daily household grind.

DOST-PNRI ends HANDA Pilipinas with nuclear tech at Visayas Leg
Capping the year with scientific solutions in facing natural hazards, researchers from the DOST - Philippine Nuclear Research Institute showcased vital nuclear and radiation technology for the HANDA Pilipinas Visayas Leg held from October 27 to 29, 2025 at the SMX Convention Center in Bacolod City, Negros Occidental.
Among the technologies featured by PNRI are the country's current developments towards a national radiological emergency preparedness and response, including radiation monitoring stations, development of radiation-processed hemostats for stopping bleeding for medical and emergency applications, and the use of isotope hydrology studies in assessing groundwater and soil contamination after flooding during typhoons or storm surges.
With the theme, “Padayon Visayas: Science, Technology, and Innovation for Resilient, Unified and Sustainable Visayas” for its last leg, HANDA Pilipinas aims to continue the push towards the increasing role of S&T in turning innovation into solutions tailored for local communities ready to face natural hazards and the challenges of economic development.
"Disaster risk reduction begins with accurate, timely and localized data. Without a clear understanding of the risks unique to each community, planning and preparation become reactive instead of proactive," said DOST Secretary Renato Solidum Jr.
"Risks are local; therefore, resilience actions must be localized."

MMSU partners with DOST-PNRI for joint nuclear R&D
Like atoms forming molecules through strong linkages, the Department of Science and Technology - Philippine Nuclear Research Institute (DOST-PNRI) has also made a new foray in academic partnerships up north as representatives from Mariano Marcos State University in Ilocos Norte signed a Memorandum of Understanding (MOU) for joint research and development on nuclear and radiation technology.
The MOU looks forward to an active cooperation between the agency and the university, particularly through joint research projects, technology transfer, exchange of data and expertise of their scientists, engineers and students, OJTs, fellowships and workshops, among others.
In particular, the parties also aim to eventually incorporate nuclear science and engineering in the curriculum of select courses and degrees.
Among the particular fields of research are nuclear science and engineering, as well as the Atom's various applications in agriculture, health and medicine, industry and manufacturing, food processing and related areas.

DEADLINE EXTENDED TO OCTOBER 22 - Call for papers for the 4th Philippine Nuclear Research and Development Conference
The Philippine Nuclear Research Institute of the Department of Science and Technology (DOST-PNRI) announces the 4th Philippine Nuclear Research and Development Conference (PNRDC 2025) to be held on December 10-11, 2025 at the PNRI Auditorium, Commonwealth Avenue, Diliman Quezon City.
This year’s conference coincides with the 53rd Atomic Energy Week (AEW) celebration, making it a significant event for the nuclear science community.
PNRDC 2025 will bring together leading experts and researchers in the country to share the latest advancements in nuclear research, development, and innovation. The conference aims to foster dialogue on nuclear science, technology, and policy, creating a platform for engagement among researchers, policymakers, and the public.
PNRDC 2025 will partner with a Scopus-indexed journal to publish a special issue on Nuclear Science and Technology. This special issue will feature full-paper versions of selected presentations from the conference, subject to the journal’s peer-review process.
Researchers, academics, and professionals are invited to submit abstracts for possible oral or poster presentations at the conference. The PNRDC offers a valuable opportunity to showcase research to a national audience and contribute to the dialogue on the future of nuclear science and technology.
