PACT Co., Ltd.

Turning Exhaust Gas into Resources

Plasma-assisted catalytic technology enabling decomposition, reforming, and synthesis in a single integrated process.

Social Implementation

PACT's Social Implementation Model

PACT Co., Ltd. bridges the gap between university and research institution findings and industry-ready solutions. We take a fully integrated approach — from R&D through field validation, device engineering, and commercial deployment — ensuring technology reaches society.

STEP 1

Research Seed Discovery & Technology Development

In collaboration with Hokkaido University and other research partners, we advance our understanding of reaction mechanisms, refine elemental technologies, and assess applicability.

STEP 2

Proof of Concept, Evaluation & Device Engineering

Tailored to the challenges faced by industry and on-site operations, we conduct proof-of-concept trials, technical evaluations, and operational design, translating results into deployable solutions.

STEP 3

Commercialisation & Social Implementation

Through joint research and technology partnerships, we pursue adoption across the environmental, energy, and chemical sectors, generating sustained value.

PACT Co., Ltd.'s positioning: Rather than allowing university research outcomes to remain dormant, we serve as the central function that gives concrete form to the journey from "Research → Proof of Concept → Device Engineering → Social Implementation."
Value

The Value We Deliver

Strengthening odour control in poultry and livestock facilities

We explore the feasibility of introducing treatment technologies to reduce odours and exhaust burdens at livestock operations.

B

Reducing treatment burden for persistent substances such as dioxins

With persistent hazardous substances in mind, we explore the potential of low-environmental-impact treatment technologies.

NH₃
C

Improving efficiency in ammonium and ammonia-related synthesis

With advances in reaction conditions and lower-temperature operation in view, we examine approaches to enhance chemical conversion process efficiency.

CO₂
D

Exploring technology to convert CO₂ into valuable products

Looking beyond greenhouse gas reduction, we pursue technology pathways that enable CO₂ to be utilised as a resource.

E

Connecting university joint research to commercialisation

To transition research outcomes into social implementation, we establish pathways to validation and commercialisation, starting from industry-academia collaboration.

F

Examining countermeasure technologies against viruses and microorganisms

Towards the advancement of safety and hygiene management, we pursue technical studies focused on neutralisation and removal capabilities.

PACT Technology

What is PACT Technology?

PACT stands for Physical And Chemical Technology. By combining plasma with catalytic reactions, it aims to create more flexible and highly efficient alternatives to processes that have traditionally required high temperatures and heavy operational loads.

What distinguishes PACT technology is that it goes beyond mere removal or decomposition — it holds the potential to connect emissions to useful resources and materials. This opens pathways not only for environmental measures, but also for resource circulation and the design of new reaction processes.

Applications span odour, exhaust gas, and persistent substance treatment; the optimisation of chemical conversion processes; and uses related to hygiene and disease prevention — with promising expansion across environmental, energy, chemical, and agricultural sectors.

Applications

Key Application Fields

PACT technology is advancing applied development centred on environmental, agricultural, chemical, and energy sectors — from exhaust gas treatment through to resource conversion.

Environment

Exhaust Gas Treatment, Odour Control & Purification

Expected applications as a processing technology that suppresses environmental burden through the reduction of hazardous substances and odour components.

Energy

Improved Reaction Efficiency & Energy Savings

We seek to redesign conventional high-temperature, high-load processes with more flexible reaction conditions.

Chemistry

Development of Novel Synthesis Processes

Looking beyond decomposition, we pursue expansion into new chemical processes encompassing reforming and synthesis.

Agriculture & Food

Environmental Improvement & Resource Circulation

Components arising from livestock, agricultural, and food industry operations are reframed through the dual lens of environmental improvement and resource utilisation.

Background

Our Founding Background

PACT founding background

PACT Co., Ltd. was established to ensure that plasma-assisted catalytic technology — cultivated over many years — does not remain confined to research outcomes, but is carried through to validation, adoption, and commercialisation. In particular, our encounter with the Plasma Process Laboratory at Hokkaido University (Professor Koichi Sasaki) became the catalyst for establishing PACT Co., Ltd. within Hokkaido University and advancing social implementation centred on industry-academia collaboration.

Academic Partnership
Hokkaido University — Plasma Process Laboratory (Prof. Koichi Sasaki)
As a partner under Hokkaido University's Industry Creation Chair programme, we are advancing PACT technology from both research and social implementation perspectives, in collaboration with Hokkaido University.
