Establishing foundations of sustainable circulation by diversifying raw materials

Advancing the diversity of raw materials for chemicals, the basis of a wide range of industries, offers a way to reduce impacts on the environment by greenhouse gas emissions and other factors, and provides a response to the depletion of fossil resources. To the chemical industry, this is an important theme which has significant meanings in both reducing risks and creating growth opportunities.
The MCHC Group employs synthesis technologies, process development technologies and plant control technologies as part of its efforts to diversify the raw materials used in its main chemical products. For instance, MMA now has the top share in the world market. We are exploring manufacturing techniques that use shale gas and biomass as raw materials in addition to naphtha and working to cement our position as the No.1 supplier.
Moreover, the new bio-based engineering plastic, DURABIO, which takes advantage of the properties of biomass raw materials, is a material boasting performance that could not be achieved through conventional petroleum-derived resins. For instance, DURABIO strikes a high-dimensional balance between various properties including transparency, weatherability, strength and optical qualities.
MCHC is also working on the development of artificial photosynthesis, viewing it as the dream technology of the carbon cycle.

Embracing coexistence with nature while protecting biodiversity

We regard coexistence with nature, and the conservation of biodiversity in particular, as one of the key shared values not only for sustainability of the global environment but also for corporate sustainability. The MCHC Group selects product lines that contribute to the protection of biodiversity based on scientific grounds, shares this value with customers and works with customers to promote its diffusion in the market.
GOBIMAT prevents the erosion of soil in rivers, ponds and other waterways which are caused by wind, rain and running water. It contains many air cavities, providing an environment for vegetation above the water’s surface and a habitat and breeding grounds for fish and aquatic insects below the surface. As technologies offering superior workability, economy and environmental friendliness, GOBIMAT is registered with New Technology Information System (NETIS) operated by the Ministry of Land, Infrastructure, Transport and Tourism, and has become a longrunning product over more than four decades.
X-sheet, a type of concrete formwork material for construction, leads to the conservation of timber resources as a substitute for wooden formwork that has traditionally been used. As X-sheet can be used repeatedly, it offers lower running costs than wooden plywood does. Moreover, since the material is semi-transparent, the work site enjoys natural illumination effects, which helps improve work safety.

Reducing energy consumption and environmental impact of society as a whole

To reduce the energy consumption and environmental impact of a society as a whole, composite and multitiered solutions that consider the big picture of the value chain are essential. The MCHC Group leverages its combined strengths in functional design and molecular design as part of its commitment to providing solutions in which a wide variety of high-performance materials and components play a key role.
For example, in the automotive field, the MCHC lineup includes a broad array of solutions embracing lighter weight, eco-friendliness and added or reinforced functionality as key concepts, including various high-performance polymers, carbon fiber and compound materials, composite products, alumina fiber, MAFTEC, lithium-ion battery materials and hydrogen stations. We incorporate the demands of customers and society as we steadily expand our business operations.
MCHC also works on developing the key materials contributing to energy-saving and lifestyle-enriching products that have spread throughout society, such as organic EL materials for displays, and gallium nitride substrates for LED lighting.

Global roll-out of water resource management and solution proposalbased projects that utilize distributed water supply systems

Water is the source of all life on the planet. It is an indispensable resource that is vital to our lives.
The MCHC Group, as “a provider of total solutions for water resource issues,”
is working toward the realization of a sustainable society by developing and providing a broad range of solutions related to water resources.

Instead of large-scale concentrated facilities including water purification plants, distributed water supply facilities maintain small-scale, independent water supply functions using local sources of water such as rainwater and groundwater. Wellthy Corporation, which provides this system, obtained Resilience Certification operated by the Association for Resilience Japan for the first time in December 2016 as a groundwater purification business.


KENYACreating communities with safe water

Working on a joint basis with the United Nations Development Program (UNDP), we installed “slow filtration equipment” that is easy to operate and manage and uses no electricity for a small agricultural community in Kenya that comprises around 40 households. Since 2013 we have been providing local residents with this filtration system, which purifies canal water, making it safe to drink. We also introduced a drip irrigation system. The system reuses the active carbon used in the water purification process to improve soil conditions, enabling the cultivation of high value-added plants and traditional vegetables. In this way, we developed a comprehensive business model where the villagers sell the purified water and vegetables at local markets to earn monetary income.

JAPANCreating a robust social infrastructure that is resilient against disasters

It is now possible to ensure water supply lifelines using groundwater membrane filtration systems during a disaster, secure drinking water for local residents and enhance the operational continuity of hospitals and government offices.
During the 7.3-magnitude Kumamoto Earthquake that struck in April 2016, all systems were activated in the disasterstricken region, while the public water supply was cut off. In addition to installed facilities, water was supplied to local residents and hospitals. The system is not only useful during an emergency. Under normal conditions, it is expected to offer the effects of lower water supply and sewage rates, and a lower environmental impact. To date, more than 1,200 systems have been installed in various regions.

MYANMARCreating a high-reliability water resource infrastructure

As it suffers from the effects of climate change, Myanmar is seeing an impact in the areas of water and hygienic environments with rising river water turbidity due to torrential rains, deteriorating water quality from tap water due to high salinity, and increased river effluent from plant and facility wastewater. Meanwhile, the environmental management technologies to appropriately grasp these impact are still not sufficiently developed. The MCHC Group launched a Myanmar site in 2017 and will contribute to improving the sustainable water resources by developing water resource infrastructure centered around distributed water supply systems in conjunction with water quality analysis projects that ensure high reliability, and through the expanded introduction of environmentally-friendly technologies.

Resilience Certification
Resilience Certification is operated by the Association for Resilience Japan, which the National Resilience Promotion Office of the Cabinet Secretariat established in February 2016 based on the Guidelines Concerning Certification For Groups Contributing to National Resilience.
Under the scheme, companies, schools, and various organizations such as hospitals are certified as “groups contributing to national resilience” for supporting the purpose of national resilience and actively engaging in initiatives concerning their own business continuity.
