Jinjiang Hanfeng Trade Co., Ltd. (SDTDID) leads athletic footwear decarbonization through our comprehensive green manufacturing initiative in Chendai, Jinjiang. Our eco-engineered footwear lines replace virgin petroleum-based materials with 100% Global Recycled Standard (GRS 4.0) certified post-consumer recycled PET polyester yarns, reducing virgin plastic consumption by 62% per production run. Midsoles incorporate bio-based EVA derived from sugarcane polyols verified by ASTM D6866 radiocarbon analysis, delivering identical resilience and 45 Shore C cushioning while cutting carbon emissions. Sole attachment utilizes zero-VOC water-borne polyurethane adhesives meeting strict EU REACH SVHC limits (< 0.1%) and California Proposition 65 standards, completely eliminating hazardous organic solvent fumes in assembly. Packaging is 100% plastic-free, utilizing FSC-STD-40-004 certified recycled corrugated cardboard boxes printed with water-based non-toxic soy inks. Verified by third-party SGS chemical testing, amfori BSCI social compliance, and ISO 14001 environmental management audits, our sustainable combat shoes provide international sports brands with documented ESG traceability from raw pellet to containerized FOB shipment.
SDTDID / Jinjiang Hanfeng pioneers eco-conscious combat footwear manufacturing conforming to the Global Recycled Standard (GRS 4.0). We utilize 100% recycled ocean-bound polyester (RPET) microfiber suede, solvent-free water-based PU bonding cements (zero hazardous VOCs), bio-based sugarcane EVA foam midsoles, and 100% FSC-certified unbleached kraft retail packaging in Jinjiang.
Sustainable Footwear Materials & Eco-Manufacturing
GRS Recycled Ocean Suede (RPET)
Constructed from 100% post-consumer recycled ocean-bound PET bottles spun into high-tenacity microfiber suede. Delivers identical tensile tear resistance (≥ 25,600 Martindale cycles) to virgin leather while reducing raw petroleum consumption by 55%.
GRS Certified Chain of CustodyZero-VOC Water-Based Adhesives
Eliminated toxic benzene and aromatic solvents from our assembly line. We utilize customized water-based polyurethane adhesives reactivated under precise infrared curves (58°C–62°C), achieving ≥ 4.2 N/mm peel adhesion without harmful emissions.
Zero Benzene & VOC-FreeBio-Based Sugarcane EVA Midsoles
Our cushioning insoles and midsoles utilize bio-based ethylene vinyl acetate derived from renewable sugarcane bagasse. Provides superior energy return and long-lasting compression resistance with a negative cradle-to-gate carbon footprint.
USDA BioPreferred Certified100% Recyclable FSC Kraft Packaging
All retail shoe boxes, wrapping tissue, and hangtags are manufactured from unbleached FSC-certified recycled paper printed with natural soy-based inks. No plastic coating or laminate film means 100% curbside curbside recyclability.
