Advancing decomposition, removal, and detoxification of hazardous substances
I'mpact World Co., Ltd. is responsible for the research, development, accumulation of technical expertise, and international expansion of PACT technology, supporting the intellectual foundation of the Impact Group.
PACTstands forPlasma Assisted Catalytic Technology. By placing plasma and catalysts in the same reaction space, PACT enables physicochemical reactions that are difficult to achieve with conventional technologies, leading to decomposition, removal, detoxification, and reduced toxicity.
Originating from the PACT concept patent granted in 1995, I'mpact World Co., Ltd. has pursued a broad range of themes since its establishment in 2003, including dioxin decomposition, C4F8 etching-gas treatment, VOC decomposition, ethylene decomposition to suppress post-harvest ripening, and virus inactivation.
Today, we work with our group company PACT Co., Ltd. to build a framework that translates research results into practical social implementation.
Scientific and technological progress has brought enormous benefits to humanity, while also creating challenges such as environmental pollution, global warming, and public-health risks. As a “doctor for Planet Earth,” I'mpact World Co., Ltd. works with group companies and like-minded businesses, organizations, and individuals to develop and promote PACT-based technologies for decomposing and removing pollutants, harmful viruses, and greenhouse-related substances.
Since the company’s founding, we have consistently pursued the potential of PACT technology and bridged the gap between R&D and practical implementation.
I'mpact World Co., Ltd. has accumulated many years of research and development in PACT technology. Our mission is to turn research results into practical technologies that help solve social and environmental challenges.
We will continue working with group companies, businesses, and research institutions to expand PACT applications in decomposition, hazardous-substance removal, and inactivation, contributing to the environmental, hygiene, and industrial fields.
PACT uses electron-orbital excitation generated by atmospheric-pressure plasma at ambient temperature to induce molecular decomposition and recombination. By allowing plasma and catalysts to coexist in the same space and time, it creates a highly efficient reaction field.
High-frequency, high-voltage power is applied to PACT electrodes to generate plasma between catalyst-treated surface electrodes. The coexistence of plasma and catalysts enables reactions that are difficult to achieve independently.
Target gases are introduced into the reaction space and their molecules are rapidly dissociated. The separated atoms and molecules are then recombined on catalyst surfaces to achieve detoxification and improved treatment performance.
By focusing not only on decomposition but also on recombination, PACT has the potential to detoxify or reduce the toxicity of environmentally harmful substances and, where appropriate, support useful recombination reactions.
Most atmospheric-pressure plasma energy is associated with nitrogen excitation, and certain excited states carry enough energy to break many molecular bonds. PACT reaction systems are designed on this principle.
Plasma is generated within PACT electrodes using high-frequency, high-voltage power, while catalyst surfaces simultaneously serve as the reaction field. This allows the process from molecular dissociation to recombination to be controlled as one integrated sequence.
Target substances are continuously introduced into the reaction field for rapid decomposition and recombination, aiming at hazardous-substance removal, detoxification, or conversion into harmless materials.
The technology is supported by research and practical results involving activation of CO₂, NO, and H₂O; CO₂ decomposition behavior; smoking-room separation technology; and suppression of droplet transmission of norovirus.
Building on years of accumulated research, we have expanded PACT into a wide range of environmental, hygiene, and industrial applications.
We established the technical foundation through the PACT concept patent, generation of ring-shaped plasma, dioxin decomposition, C4F8 etching-gas treatment, and other fundamental and applied research.
In addition to developing VOC decomposition systems, applications expanded to ethylene decomposition for controlling post-harvest ripening, deodorization of animal laboratories and smoking rooms, and indoor-air purification.
We have also advanced applications for virus inactivation and microbial reduction, evaluating their potential for hygiene and infection-control measures in enclosed spaces.
PACT devices and systems are designed on the assumption that they will be customized or newly developed for each application. The following are representative examples.
A compact device in which the blower fan also serves as an electrode, generating a ring-shaped plasma region.
A multilayer device designed for high airflow and continuous treatment applications such as VOC removal and deodorization.
