SDGs for Kaltech

Kaltech’s photocatalytic technology
contributes to a sustainable society.
Development of unique andexcellent photocatalysts

Joint research on photocatalysts
to benefit society

Proprietary photocatalyticmaterials

Verifying effectivenessagainst viruses

Photocatalytic filter

Photocatalysts represent Kaltech’s corecompetence. The performance of aphotocatalyst is dramatically improved byapplying a unique process to titanium oxide, its
main material. This material know-how is
Kaltech’s “secret sauce.” We are currently
conducting further material development aimed
at realizing a “super photocatalyst.”

Pond water purification
experiment

In addition to basic research, we are conducting
joint research with universities and research
institutes to expand the range of photocatalyst
applications to everything from household
appliances to numerous industrial applications.
We are conducting demonstration experiments
aimed at applying photocatalysts’ air-purifying
effect to hospitals, vegetable/fruit factories, anddistribution systems, and water-purifying effectto land-based aquaculture and pond waterpurification.

Helping solve society’s problems
Contributions throughbusiness

Contributions throughcommunity activities● Air purification that creates
safe and secure spaces● Reduction of food loss
● Design that doesn’t get in the way of livingspaces● Resource circulation and utilization● Donations of products to
shopping districts and other commercialorganizations to revitalize local economies● Donations to sporting organizations tostimulate amateur sports● Cooperation with support groups to help
disabled persons live independently

Purifying air and water with photocatalysts
Kaltech’s unique photocatalytic technology
purifies air by decomposing airborne organic
substances such as viruses, fungi, and odors.
Besides shipping sterilization and deodorizing
machines equipped with photocatalytic
technology around the world, we are also
applying photocatalysis to water purificationas part of efforts to expand the range ofapplication of this technology.

Photocatalytic filter can be washed and used many times
The photocatalytic filter can be repeatedly
cleaned and reused, maintaining its sterilizing
and deodorizing effect. You get long-term
usage, and you reduce waste since there’s noneed to replace the filter.

Reducing food loss
The Food Fresh Keeper, a box that maintains food’s freshness atroom temperature, utilizes Kaltech’s photocatalytic technology tokeep air inside it clean. For example, by suppressing the growth ofmold on bread and decomposing ethylene gas emitted from food,
we believe the box will contribute to reducing food loss.

Using forest thinning wood as part of our products
The handle of the Food Fresh Keeper is made of Yoshino cypress
obtained from forest thinning in Nara. It is made by Yoshitatsu
Shoten, which, like Kaltech, wants to protect the environment andis committed to Japanese products. Yoshitatsu Shoten makes
structural pillars from the core of the timber, then uses theremaining wood to make chopsticks and Food Fresh Keeper
handles.

Cardboard packaging box is made from recycled paper
Kaltech’s environmental consideration goesbeyond the products themselves. For example,
our product cardboard boxes are made fromrecycled paper and no longer use excessive
colors in the design, thus reducing platemaking film and ink.

Supporting sports activities
We contribute to amateur sports by cosponsoring a variety of sporting events. Theseinclude the 12th Japan National Junior HighSchool Wrestling Invitational (November 2021),
the 18th All Japan Aerobics Championship(December 2021), and the Japan National
Junior High School Skating Competition(February 2022).

Cooperating with merchants to stimulate the local economy
Semba Shinsaibashisuji Cooperative (July2021); four local merchant associations near
the National Stadium (August 2021); Dotonbori
Store Association (September 2021); others.
Amid an economic downturn due to thepandemic, we have supported local merchantassociations and cooperatives. To helpstimulate local economies, we donated Kaltech
products to shops and cooperatives in order toprovide a safe and secure space for customer
interaction.

In January 2022, we cooperated in the Paralym Art* World Cup
2021, an event celebrating artists with disabilities. Everyone who
participated in the award ceremony wore our portable air purifiers
around their neck. As a cooperating company, we engaged in
activities such as presenting the Kaltech Award to excellent works.
