Environment

We established our Environmental Problem Project Team in 2002 with the goal of becoming an "Environmentally Friendly Morimura." Then, in 2007, we formulated Environmental Policy, which incorporates our founding spirit, and introduced the Environmental Management System to vigorously and systematically promote actions for protecting the global environment. We acquired ISO14001 certification, an international standard for environmental management system, in March 2008.
Taking advantage of functions only available to trading companies, we produce products and technologies that help reduce environmental impact as well as products the exert low environmental impact in production processes in Japan and overseas. We strongly supply and encourage the use of these products and technologies across society.

Becoming a global, environmentally friendly corporation

We acquired ISO14001 certification, an international standard for environmental management system, in March 2008.

We acquires ISCC PLUS Certification

We are pleased to announce that MORIMURA BROS., INC. (Head Office: Minato-ku, Tokyo) acquired ISCC PLUS^*1, an international certification system for sustainable products.

ISCC PLUS ensures that certified items, such as biomass and recycled raw materials, are properly managed via the use of the mass-balance approach^*2 throughout their supply chains, including manufacturing process.

MORIMURA BROS., INC. undertakes and declares to comply with the ISCC PLUS requirements in accordance with the latest ISCC regulations.

*1 ISCC PLUS:

International Sustainability and Carbon Certification (ISCC) is an internationally recognized certification program for sustainability and carbon emissions. ISCC PLUS is especially designed to ensure that certified items, which are bio-based or recycled raw materials and products marketed in the EU and elsewhere in the world, are properly managed throughout their supply chains in terms of sustainability and CO₂ emissions.

*2 Mass-balance approach:

A method for assessing the sustainability of products made using multiple types of raw materials, including biomass and recycled raw materials as well as fossil-based raw materials. In this method, characteristics of sustainable raw materials (e.g., biomass and recycled raw materials) included in finished products are taken into account in a manner that reflects the proportional volume of such raw materials.

We will continue to work towards exploring and offering products aimed at a sustainable world and building a supply chain that enables a stable supply in the long-term, which are both important issues (materialities) for us. We will do so by expanding the handling of ISCC-certified products.

Our Initiatives

Heat-resistant ceramic catalysts for exhaust gas treatment

MORIMURA BROS., INC. has begun selling heat-resistant ceramic catalysts manufactured by Shanghai FT Technology Co., Ltd. (F-Tech), which can be used for exhaust gas treatment at factories.
Hazardous substances (volatile organic compounds, VOCs) contained in exhaust gases from factories can have adverse effects on human health and the environment. As a means of disposing of these harmful substances, factories use regenerative thermal oxidizer (RTO) systems, in which they are rendered harmless by burning at high temperatures of around 800°C or higher. At the same time, there are issues such as increased fuel costs and increased CO₂ emissions due to the combustion process. One solution contributing to overcoming these issues is a heat-resistant ceramic catalyst installed inside RTO systems. This catalyst uses a material developed by Murata Manufacturing Co., Ltd., that can efficiently process harmful substances. This heat-resistant ceramic catalyst is expected to reduce both VOC emissions and costs at the same time.

Zgaia™ low-temperature sintered zirconia for reduced environmental impact

We have been selling zirconium oxide products (zirconia) manufactured by Tosoh Corporation for several decades, primarily in Asia.
Tosoh succeeded in mass-producing zirconia in the 1980s, and maintains the world's top market share in the field of fine ceramics.
In 2021, they developed the Zgaia™ series of zirconia, which can be sintered at a lower temperature (1,250°C) than conventional zirconia (1,500°C), and can therefore be expected to reduce CO₂ emissions by lowering sintering temperatures.
Tosoh has also succeeded—for the first time in the world—in the development of Zgaia™ 1.5Y-HT, a low yttria (Y₂O₃) grade, for which it was impossible to obtain as a sintered material with conventional zirconia, achieving both high strength and a high degree of toughness. This will result in the emergence of new functions, and is expected to be used in various applications in the future.
We will continue to remain close to the development of innovative technologies and expand applications and markets for zirconia.

Utilizing wine pomace, a winemaking byproduct

Wine pomace is the name given to grape skin and other solid remains left over during the winemaking process. Over 10,000 tons of pomace are produced annually in Yamanashi Prefecture alone, but most of it is incinerated as industrial waste. At MORIMURA BROS., INC., we had been looking for ways to reuse that wine pomace.
Through a process of trial and error, and with the cooperation of our partner companies, we developed wine pomace extract (for flavoring applications), extracted by steam distillation of wine pomace, and have been proposing it as a product to beverage manufacturers since 2022.
When added as a flavoring, this extract has been found to enrich the flavor of wine, and enhance citrus flavors.
At the same time, it is difficult to ensure stable quality because the characteristics of the available wine pomace differ depending on the winery, grape variety, and various seasonal factors.
We will continue to make improvements, and aim for the adoption of wine pomace extract for use in both alcoholic and non-alcoholic beverages.

Magnesium Alloy Recycle Business

Since the 1980s, we have been importing and selling magnesium alloys used in die-casting, predominantly for the automotive industry. We encountered issues as the market grew, having been unable to recycle scrap generated during component manufacturing or offer disposal method suggestions for residues.

To solve these issues, we partnered with Onoda-Shoten to establish Onoda Morimura Magnesium Co, Ltd. in Toki, Gifu, to recycle magnesium alloys. This established a recycling and disposal flow in Japan.

Magnesium alloy ingot

Producing secondaly magnesium ingot uses less energy and generates lower CO₂ than primary magnesium ingot production, leading to a reduced impact on the environment. We also established a magnesium recycle plant in the Chonburi province of Thailand in 2008, which also contributes creating new employment opportunities.

Manufacturing Innovations Using Additive Manufacturing

We sell metal powder used in 3D printers made by AP&C (Canada), a subsidiary of Colibrium Additive（Former GE Additive）, in both Japan and South Korea.
The benefits of manufacturing with additive manufacturing (3D printing) are highly compatible with the SDGs.

Some examples include:

1) Reductions in waste material from the manufacturing process
2) Reductions in stock parts and local consumption of locally-produced goods
3) Contraction and simplification of the supply chain (reductions in costs and CO₂)
4) Improvements and optimization of production efficiency (compatibility with DX)
5) Contributions to industrial and technological innovation by producing high-grade components that can only be made through additive manufacturing

Metallic materials are already on the market for the aerospace, medical, and die-cast industries and are being considered as a mass production technology for automobiles. Resin materials were greatly utilized to make up for the pandemic-induced lack of medical supplies, and initiatives to put the technology into practical use have been accelerating as a dominant technology in various fields for achieving a sustainable society.

Achieving a Circular Society through Use of Reclaimed Resin

We sell reclaimed resin for use in toiletry products, onboard automotive battery parts, writing utensils, and more. Reclaimed resin is shipped after molded plastic products undergo various processing, including pulverization, washing, separation, dehydration, combination, and extruding granulation. Because of these processes, it costs more than virgin materials made from crude oil, and it did not penetrate the market quickly. In recent years, however, demand has grown against the backdrop of increased environmental awareness and reductions in recycling costs.
We are now working to expand the market further, focusing on applications where reclaimed resin has not been utilized because of safety or other quality concerns, including detergent containers, outside air conditioning units, and washing machine pans.

Expo Booth Using the Zero CO₂ System

We utilized a zero CO₂ booth system while presenting a booth at the TCT Japan 2022 expo.
This system was first introduced in 2022 by expo organizer JTB Communication Design. In concrete times, this system utilizes carbon offsets using green power certificates to replace the electricity used in exhibit booths with next-zero CO₂ emissions.
As we have many opportunities to host booths at expos, we will continue to promote our sustainability activities, which include our contributions to the SDGs and carbon neutrality, from familiar places by utilizing this system.
