Ageless oxygen absorbers Preserves the freshness and taste of food for longer periods

Helping reduce the amount of wasted food

Benefits for the environment

Ageless can keep food tasting delicious and fresh for relatively long times, which leads to less food being thrown away due to mold, discoloration, or loss of flavor. That also helps reduce the amount of times food needs to be produced and delivered, which ultimately means less CO2 emissions.

How Ageless works

Ageless is mainly comprised of specially processed iron powder. One property of iron is that it bonds with oxygen as it rusts. That allows Ageless to effectively absorb the oxygen in an airtight package, thereby preventing adverse effects from oxygen and oxidation on the items in the package.

The effectiveness of Ageless in preserving food

Testing the ability of Ageless to prevent mold

Under experimental conditions, the colonization of blue mold was observed on castella sponge cake either in packaging containing an Ageless sachet, in nitrogen flushed packaging, or exposed to the air.

Cleaning agent for air conditioning equipmentDESLIME

Cleans air conditioning equipment and saves energy

Benefits for the environment

When a biofilm firms inside air conditioning equipment, thermal efficiency declines and excess energy is consumed. DESLIME contributes to energy saving by easily removing this biofilm.

  • Simple cleaning operation

    Place DESLIME equal to
    5% (standard use concentration)
    of the water capacity in the water reservoir.
    Use the pump to circulate the water for
    one to two hours.

  • Environmentally friendly

    After cleaning, DESLIME breaks down to non-toxic water and oxygen.

  • Cleaning fluid has a neutral pH

    DESLIME has almost no impact on equipment materials.

  • Excellent dispersion and separation force

    DESLIME is a peroxide-based cleaning agent that penetrates and removes accumulated biofilm in air conditioning equipment.

Taking advantage of its excellent chemical resistance, MX-Nylon is also used for chemical and fragrance bottles as well as bleach (chlorine bleach) and ink containers, and can preserve contents for long periods and prevent the leaking of odors.

Development to also achieve carbon neutrality

MX-Nylon, to be produced at MGC’s Niigata Plant, has acquired ISCC PLUS certification, an international certification system for sustainable products.
With this certification, MGC will begin manufacturing and selling ISCC PLUS-certified MX-Nylon, which is manufactured from sustainable raw materials as per the mass balance approach .
In order to meet the carbon neutral goal, by conserving energy in its manufacturing process and actively using plant-derived raw materials, MGC is working to achieve net-zero CO2 emissions when manufacturing.

Environmental (atmosphere, water quality, soil) protection

Direct methanol fuel cellsEnabling quiet and clean power generation

Supplies power without emitting any NOx, SOx,
particulate matter or other atmospheric pollutants

Benefits for the environment

Direct methanol fuel cells (DMFCs) produce power through a chemical reaction, so they operate quietly and emit no atmospheric pollutants. They can also continuously supply electricity for several consecutive days.

Comparing the performance of DMFCs with other emergency power supplies

DMFCs are clean sources of energy that operate at low noise levels, and meet high-performance standards for applications that require relatively low output of electricity to be supplied continuously for long periods of time. Since the cells are also compact, they can be installed in small spaces for use in times of emergency.

How DMFCs work

DMFCs generate electricity by producing a chemical reaction using methanol and air. DMFCs can continuously supply electricity as long as they are filled with methanol.

Dimethyl ether A clean fuel derived from methanol

Emits comparatively low amounts of NOx and no
SOx and PM during combustion

Benefits for the environment

MGC produces dimethyl ether as well as methanol from natural gas produced as a by-product of oil drilling, thereby making effective use of resources from an environmental perspective. Dimethyl ether is also being promoted as a clean fuel because it emits no sulfur oxide (SOx) and particulate matter (PM), which are emitted when burning diesel oil or kerosene.

Aerosol spray cans
As an alternative to chlorofluorocarbons (CFCs), MGC's dimethyl ether is used in aerosol spray cans as a propellant.

Plastic greenhouses
MGC is aiming to commercialize dimethyl ether as a greenhouse boiler fuel that facilitates cultivation since it emits CO2 needed for the growth of plants and produce while also providing heating.

MGC's dimethyl ether can be used as a clean diesel fuel for trucks.

Meta-xylenediamine A highly weather-proof epoxy coating

Contains absolutely no organic solvents

Benefits for the environment

MGC's meta-xylenediamine (MXDA) epoxy coating is comparatively friendlier to human health and the environment than conventional products because it is water-based and contains no organic solvents, which are a cause atmospheric pollution. Compared with ordinary curing agents, about 20% less volume of MXDA is needed to get the same hardening performance, which ultimately contributes to conserving oil resources.

Comparing MXDA and an ordinary curing agent by the amount of needed for the same performance

Hydrogen peroxide An environmentally friendly pulp and paper bleaching agent

Hydrogen peroxide is used as a bleaching agent that
does not harm marine ecosystems because it
decomposes into water and oxygen

Benefits for the environment

Hydrogen peroxide is a chemical compound that has been used as a bleaching agent and an oxidizer for many years. It produces no harmful by-products since it decomposes into water and oxygen. Consequently, hydrogen peroxide is in demand for various applications as an environmentally friendly chemical.

Using hydrogen peroxide instead of chlorine to bleach paper products

After successfully manufacturing hydrogen peroxide for the first time in Japan in 1933, MGC went on to become one of the world's leading producers of this substance.
