With the rapid green transition of global supply chains, sustainable procurement has become a key strategic pathway for enterprises to address climate change, fulfill social responsibility, and advance high-quality development. Studies show that up to 90% of corporate greenhouse gas emissions originate from supply chain activities. As a result, building a responsible, transparent, and low-carbon procurement system is becoming the shared priority of leading companies worldwide.

Recently, YINO Biologic successfully passed the SGS assessment and officially obtained the ISO 20400 Sustainable Procurement Guidance Performance Assessment Statement. This milestone demonstrates the company’s deep alignment with international sustainability standards in supply chain governance, responsible sourcing, and green manufacturing. It also signifies YINO’s transition toward a more mature, systematic, and sustainable stage of green supply chain management.
As the world’s first and most widely adopted international standard for sustainable procurement, ISO 20400 uses strategic systems, process management, and life-cycle thinking as its core framework, guiding enterprises to integrate environmental responsibility, social responsibility, and economic value into procurement decisions. As a designated “Green Supply Chain Management Enterprise” in Shandong Province and a leading manufacturer in the bio-based chemical sector, YINO Biologic has long regarded sustainable procurement as a central driver of green value-chain development. Under the guidance of the ISO 20400 framework, the company has shifted from traditional cost- and quality-based decision-making to a multidimensional model incorporating environmental impact assessment, social value creation, supply chain risk control, and compliance governance—transforming procurement management from fragmented practices into a measurable, auditable, and continuously improvable system.
At the starting point of its green supply chain, YINO Biologic adopts corncob non-food biomass as its primary raw material, achieving renewable and environmentally friendly sourcing through the resource-based utilization of agricultural residues. Corncobs serve not only as an essential feedstock for the company’s bio-based chemicals but also as the foundation and symbol of its sustainable procurement system. Through the establishment of a Sustainable Procurement Management Manual and supporting procedural documents, YINO has realized full transparency and traceability across its supply chain. Risk identification, supplier compliance reviews, and life-cycle impact assessments are rigorously implemented at every procurement stage to ensure that the entire supply chain meets ISO 20400’s requirements for responsible sourcing at enhanced standards.
At the strategic level, YINO has deeply integrated its sustainable procurement system with the company’s 2030 and 2050 carbon-reduction targets. Clear carbon-management pathways and quantifiable performance indicators ensure that low-carbon principles are embedded throughout procurement activities, continuously advancing the greening of product life cycles. This system not only reduces the company’s own carbon emissions but also enables YINO to provide global customers with safer, lower-carbon, and more efficient raw material solutions.
Recognizing that sustainable procurement requires long-term collaboration across the entire value chain, YINO Biologic—acting as a chain-leading enterprise—regularly provides sustainability training, compliance briefings, green project co-creation, performance evaluations, and continuous improvement initiatives for its supply chain partners. Through professional empowerment and shared standard-building, the company is driving the entire industry toward greener, more transparent, and more responsible development—accelerating the formation of a green value community and raising the sector’s overall sustainability performance.
Achieving ISO 20400 certification not only positions the company against an internationally recognized management benchmark but more importantly reflects YINO Biologic’s firm commitment to long-term sustainable development. The company has already obtained ISO 9001, ISO 14001, and ISO 45001 certifications; completed ISO 14067 Product Carbon Footprint (PCF) accounting; and joined the United Nations Global Compact (UNGC) and the EcoVadis sustainability rating system (Bronze). Together, these initiatives form a sustainability framework centered on green, responsibility, and transparency—spanning raw material sourcing, production, supply chain collaboration, and customer delivery.
Looking ahead, YINO Biologic will continue to advance the integrated pathway of “corncobs → bio-based platform chemicals → high-value green materials.” Through higher standards, more scientific methodologies, and more decisive action, the company will promote the non-food bio-based industry toward more sustainable, higher-quality, and globally competitive development. The achievement of ISO 20400 is not an endpoint but a new starting point—propelling YINO toward stronger sustainability governance, a more responsible supply chain system, and greater global influence as a green manufacturing enterprise.
