1. Brand Heritage & Manufacturing Integrity

Est. 1883 (Meiji 16): Originated as Murata Factory producing hand-woven dantsu(traditional Japanese rugs).
National Landmark Projects: Carpet & upholstery supplied to the National Diet Building, Imperial Palace receptions, and Bulgarian-style historic venues.
Firsts in Japan: Japan’s first tufted carpet tile (1970s), first railway moquette (1899), first horizontal-recycle carpet tile (ECOS®).
Production: Vertically integrated Japanese plants — spinning, dyeing, tufting, and backing — ensuring tight QC and consistent lot matching.

2. Core Sustainable Technologies

ECOS® Horizontal Recycling System

Unlike downcycling, SUMINOE’s ECOS® carpet tiles employ horizontal recycling:

Post-consumer carpet → separated → re-pelletized → re-extruded into new carpet tile face yarn & backing.
Some ECOS grades contain up to 77% recycled content (industry-leading in Japan).
Reduces CO₂ emissions by approx. 19% vs. virgin nylon production.
Contributes to LEED MRc3/Mrc4 (Recycled Content) and BREEAM Mat 04.

Triple Fresh II® — Passive Deodorizing & Antimicrobial

A metal-salt-based finishing technology embedded in the fiber (not a coating):

Continuously decomposes formaldehyde, tobacco odor, pet/body odors — no UV light or electricity required.
Inhibits bacterial/fungal growth on carpet surface.
Permanently active for the product’s life — does not wash out.

F★★★★ (F4-Star) & Low VOC

Tested at 65°C in sealed chambers per Japanese JIS A 1901 — far exceeding typical room-temp VOC tests. Safe for hospitals, daycares, and sealed office towers with underfloor air return.

Size: Standard 500×500 mm modular tiles; select lines in 25×100 cm planks.
