IRPC One Report 2022 EN

Ongoing Projects In 2022, IRPC implemented projects that focus on creating value for communities surrounding the industrial zone and the society as a whole. Details are as follows: Prosthetic Leg Project IRPC has implemented a prosthetic leg project by donating Polypropylene (PP) plastic pellets to the Prostheses Foundation under the patronage of HRH Princess Mother for the production of prosthetic legs for amputees to help improve their quality of life under the Creating Shared Value (CSV) approach. In so doing, the company was able to use its commercial products for the benefit of people with disabilities, creating shared value in the process. The project has been ongoing since 2011. IRPC has donated Polypropylene pellets to the foundation for the production of prosthetic legs delivered to persons with disability free of charge. IRPC’s plastic pellet products have been delivered for the production of prosthetic legs at the head office of the Prostheses Foundation in Chiang Mai for distribution not only throughout Thailand but also to neighboring countries, such as Malaysia, Myanmar, and Cambodia. The foundation’s prosthetic leg production facilities were set up at 95 hospitals across the country. In addition, the plastic pellets were also sent to the prosthetic leg factory that the Prostheses Foundation helped set up at the military hospital in poverty-stricken Republic of Burundi, Republic of Senegal where many people lost their limbs during political unrest, and in Banda Aceh, Indonesia, where many had their legs amputated after being injured in the tsunami disaster and political unrest as well as other causes. Between 2011 and 2022 (as of September 30, 2022), a total of 35,955 prosthetic legs have been produced and delivered to people who needed them using IRPC's plastic pellet products. In addition, IRPC in collaboration with the Prostheses Foundation under the patronage of HRH Princess Mother to host the 157th mobile prosthetic production workshop at IRPC Sport Complex, Rayong Province on July 17-22, 2022. The company provided financial support and the use of facilities to host the prosthetic production workshop, which made 94 prosthetic legs for persons with disability in Rayong and nearby provinces free of charge. Prosthetic Hand Project The Prosthetic Hand Project is a project initiated by Thai Reach Group, consisting of medical personnel and staff of Sirindhorn Hospital in Khon Kaen Province. They produced prosthetic hands with 3D printing technology, using Thermoplastic Polyurethane (TPU) and Polylactic Acid (PLA). The design of the prosthetic hand, inspired by simple mechanisms of hand puppets. Cheaply produced polymer parts and components of the prosthetic hand are held together by strings and rubber bands that can be easily repaired, reassembled when damaged or replaced when the user gains weight or their physiology changes. Thanks to the low cost of production, the Prosthetic Hand Project made it possible for the company to help society and improve the quality of life of people with disabilities, giving them quicker access to prosthetics. This corresponds to IRPC’s corporate social responsibility concept of building networks to help society using its commercial products, innovation, and body of knowledge. In 2022, IRPC conducted research and development of products for use in the production of prosthetic hands in collaboration with Sirindhorn Hospital in Khon Kaen Province. The material and chemical R&D team from IRPC Innovation Center delivered TPU and TPV Filament products to the Thai Reach Group at Sirindhorn Hospital in Khon Kaen Province for usability testing so that testing results and feedback can be used to further develop products with quality and properties best suited for the production of prosthetic hand and fingers for persons with disability using 3D printing technology. 141 Business-Driven Sustainability IRPC PUBLIC COMPANY LIMITED
