About

What We Do

Impact Group promotes research, development, and social implementation in the environmental field through plasma technology. We do not separate research, design, equipment development, evaluation, and business deployment, but aim to create value through an integrated end-to-end approach.

We focus not only on producing research outcomes, but on connecting them to equipment and systems that can actually be used in the field. We believe that sustainable progress in environmental technology requires core technologies, applied technologies, and implementation strategies to remain connected, not fragmented.

Within the group, each company takes on a distinct role, including R&D for decomposition and inactivation, commercialization of reforming and synthesis, and the development of equipment manufacturing and mass-production capabilities. These companies work together in close coordination.

Integrated Execution Capability

By connecting research, engineering design, equipment development, and business development as one continuous flow, we shorten the path to implementation.

Technology and Strategy as Twin Engines

We design not only advanced technologies, but also evaluation frameworks, collaborative research structures, and plans for mass production and deployment to shape viable businesses.

Technology

The group’s core technologies are built around three pillars: decomposition and inactivation, reforming and synthesis, and equipment development with growth strategy. Each stands as an independent domain while creating value through close coordination with the others.

Decomposition / Inactivation

This domain focuses on treatment and suppression in real environments, targeting odors, VOCs, hazardous substances, microorganisms, and related challenges.

Reforming / Synthesis

We develop technologies that use plasma and catalytic reactions to enable material transformation and high-value-added synthesis.

Equipment Development / Growth Strategy

We move from technical evaluation and demonstration to deployment design and partner collaboration, with both social implementation and business growth in view.

Industry-Academia Collaboration with Hokkaido University

Through collaboration with Hokkaido University, we are advancing initiatives that connect research with industrial implementation. By linking academic expertise with a business-oriented perspective, we aim to achieve both continuous research outcomes and practical use in society.

PACT Technology and Development Vision

With PACT at the core, we are advancing technology development from a broad perspective that includes reforming, synthesis, technical evaluation, and growth strategy. We are also exploring specific application themes such as compact deodorization and VOC treatment systems, as well as ammonia-related technologies, along with other practical use cases.
