Environmentally Friendly Products
Developing Environmentally Friendly Products
We are committed to sustainability by offering products that support global environmental conservation. In fiscal 2023, sales of these environmentally friendly products reached 85 billion yen.
Saving Energy and Labor
E Glass Fiber (chopped strands)
Used in plastic automobile parts, this material reduces vehicle weight.
G-Leaf™ ultra-thin glass
At just a few micrometers thin, G-Leaf™ not only lightens devices but also enhances manufacturing efficiency with its roll-to-roll process. It also eliminates the need for chemical glass slimming, reducing its environmental footprint.
Lumiphous™ phosphor-glass composite
This wavelength-converting material expands the range of applications for energy-efficient LED lighting.
Glass powder for LTCC
(low temperature co-fired ceramics)
By incorporating highly conductive gold or silver in the inner layer of the conductor, circuit boards made with this glass powder deliver excellent electrical performance and save energy.
Creating Energy
E Glass Fiber (roving)
This glass fiber serves as reinforcement for the plastic blades of wind turbines and shows potential for reinforcing hydrogen gas tanks in fuel-cell vehicles.
All-solid-state sodium-ion secondary battery
NEG’s proprietary glass-ceramics technology integrates the anode, cathode, and solid electrolyte, all composed of stable oxides, into a strong, unified structure. This innovative battery operates in extreme conditions (–40°C to 200°C) with no risk of fire or toxic gas emissions. Using sodium, a readily available resource, it also alleviates concerns about raw material procurement.
Ultra-thin cover glass for artificial satellite solar panels
This cover glass protects satellite solar cells from ultraviolet light deterioration in outer space while also reducing their weight.
Reducing Environmental Impact
High-efficiency deep UV transmitting glass
Designed for use in LED antiseptic lamps, this glass helps replace lamps that contain environmentally harmful mercury.
Glass Fiber Recycling
We have developed a recycling technology that recovers materials such as polishing sludge, electrostatically collected dust, and dust primarily composed of boric acid from the gas waste vaporized by molten glass. These recovered materials are then reused as raw materials for glass production.
Traditionally, glass fibers used to reinforce composites undergo surface treatment with organic materials. These agents bundle and protect the fibers while ensuring proper adhesive strength with the resin. However, the surface treatment complicates recycling efforts, and the scraps and other material lost during production are often disposed of as waste by many glass fiber manufacturers.
At NEG, we’ve eliminated the need for surface treatment agents. With our pulverization technology, we can now reuse this waste, repurposing it as raw material for new glass production.
