Business 01
Compact DAC Units – Raising Awareness with the World’s Smallest Direct Air Capture Device
DAC (Direct Air Capture) technology captures CO₂ directly from ambient air.
Our system uses a salt-based chemical solution to selectively absorb CO₂ while allowing nitrogen and oxygen to pass through.
While DAC facilities in the West are growing larger, CRRA has achieved comparable capture performance with compact units.
We’ve named our CO₂ capture system “Hiyasshi”, a product designed for everyday spaces.
With a capture efficiency of up to 84%, one unit can offset the CO₂ emissions of one person.
It also visualizes CO₂ concentration in the surrounding air through an expressive face displayed on the monitor, intuitively raising environmental awareness at home and in the office.
As of July 2025, CRRA is conducting validation tests for the implementation of its newly developed powdered CO₂ absorbent: amine-modified porous silica.

A resource-circulating unit with low environmental load.Its playful design prompts people to rethink CO₂ and embrace reuse.
Launching "Hiyasshi Papa" – Our Scalable Industrial DAC Solution
The commercial DAC unit “Hiyasshi Papa,” equipped with our proprietary absorbent, can capture approximately 30 tons of CO₂ annually from offices and factories. The recovered CO₂ can be sold at market-competitive prices for industrial use and other applications.
This system enables companies to both contribute to the environment and recover their equipment investment through CO₂ sales. We redefine DAC units—not as a cost center, but as a revenue-generating asset.
By promoting compact, decentralized DAC systems, we aim to build a new decarbonized society where everyone can participate.

Unique Technology Supporting Commercial Deployment
Amine-Modified Porous Silica
A next-generation CO₂ sorbent combining high efficiency,
low cost, and safety
With CRRA’s proprietary synthesis method, this new material offers greater efficiency and lower cost than conventional physical or chemical CO₂ sorbents.
It safely captures CO₂ and can be reused—offering both economic and environmental benefits.

Reusable
With Japan’s aging population, the demand for CO₂ sorbents in healthcare is rising—particularly in fields like anesthesia management during surgeries and intensive care. These applications are expected to become increasingly important.
CRRA is currently developing proprietary CO₂ sorbents based on Amine-Modified Porous Silica. Among several application areas, we are actively exploring their use in the medical CO₂ sorbent market, especially in anesthesia systems.
These sorbents are reusable and offer excellent cost performance, making them a promising sustainable alternative to conventional single-use products, which face issues of waste and cost.
Looking ahead to 2026, we are working toward a broader deployment of CO₂ sorbents across the entire medical field, including integration with DAC systems. Rather than focusing solely on “capturing” CO₂, our goal is to realize its social utility.
CRRA is steadily advancing the future of next-generation CO₂ utilization, starting with healthcare.

Business Area 03
Leading the Sustainable CO₂ Market with "Clean CO₂"
While global consensus continues to grow around the need to reduce CO₂ emissions, CO₂ also remains an essential raw material across industries such as agriculture, beverages, and chemicals. In fact, industrial demand is steadily rising, with some projections estimating a 26-fold increase by 2030 compared to 2024.
Despite this growing demand, the supply of CO₂ remains unstable. With mounting pressure to reduce emissions, the risk of CO₂ shortages for industrial use is increasing. At CRRA, we see this gap as an opportunity to lead. Using our original sorbent and DAC (Direct Air Capture) technology, we are developing a system to collect and supply CO₂ directly from the atmosphere.
Our sorbent enables low-cost CO₂ capture and desorption as a high-purity gas. This allows us to offer industrial-grade clean CO₂ suitable for a variety of applications.
CO₂ captured from air carries extremely low environmental impact and offers unique branding value. For example, labels such as “Cabbage grown with Hokkaido air” or “Craft beer brewed with air-derived CO₂” can appeal to consumers and businesses alike, sparking new value creation in the market.

“Hiyasshi-Papa” CO₂ Circulation Model Case
We’re bridging CO₂ reduction and reuse to build a supply chain
where decarbonization meets growth.
Growth Strategy | Phase02
CO₂ to Ethylene : A New Frontier in Circular Innovation
Turning CO₂ captured from the air into ethylene using electricity, and converting it into a variety of valuable products — this is CRRA's next bold challenge.
Ethylene is a key raw material used in the production of plastics, synthetic rubber, pharmaceuticals, detergents, and other high-value-added products. We aim to expand the synthesis and research of next-generation materials based on CO₂-derived ethylene, redefining carbon not as “waste” but as a “resource” through new circular applications of CO₂.
Toward the industries and lifestyles of the future —
The possibilities unlocked by the CO₂ molecule start here.

Shaping the Future of the CO₂ Economy
The existing CO₂ economy centers on systems like emissions trading, mainly among corporations. But these mechanisms often fail to ensure real reduction or involve individuals.
CRRA introduces a new CO₂ economy: starting with fun, family-friendly “Hiyasshi” activities that capture CO₂ from air, we build a digital reward system based on removal volume—bringing financial benefits to both users and companies that join the effort.

We envision a future where CO₂ is not just reduced, but used as a resource—and even circulated as currency. Imagine an airport serving as a hub in a world where CO₂ drives both innovation and the economy.
To achieve this, we are developing a system where consumers earn "miles" in return for supporting businesses that contribute to CO₂ recovery. By linking this incentive to daily-life spending—such as food, transportation, and daily necessities—we offer tangible value to consumers. As a result, residents, companies, and municipalities can all benefit, creating cities where environmental action translates into everyday rewards.
What we aim to deliver is not just a climate solution—it's a new kind of value.
