Summary
Torise is a trusted compostable resin manufacturer with 14 years of experience, producing 50,000 tons of biodegradable raw materials per year in a 50,000 m2 plant. Our resins are derived from non-food plants and fully degrade into water, CO2 and biomass under industrial composting conditions (EN 13432, OK Compost and BPI certified). Our PBAT PLA compostable pellets (TRBF90/TRBF96) are suitable for a variety of applications including compostable bags, food packaging and agricultural films.
Introduction
As plastic bans tighten around the world (e.g. the EU Single-Use Plastics Directive), brands are desperate for suppliers of certified biodegradable resins – yet variable quality and "pseudo-compostable" claims plague the market. Procurement managers face tough challenges: How to verify supplier credibility? How to balance cost and compliance? This guide outlines a practical, four-pillar framework for assessing suppliers, backed by Torise Biomaterials' 14 years of expertise as a certified compostable resin manufacturer.
Certified Compliance: A Non-Negotiable Benchmark
Importance: Certifications such as TÜV OK Compost Industrial, BPI and EN13432 verify the full degradability of a resin under composting conditions.
Industry Pitfalls: 37% of "biodegradable" resins do not comply with EU standards due to lack of certification (2023 Greenpeace report).
✔Torise's Solution:
●All resins are pre-certified to global standards (view certificates).
●Guidance on certification authenticity verification is provided free of charge (e.g. TÜV online database check).
Production Capacity: Scale Equals Reliability
Importance: Suppliers with annual production of more than 50,000 tons minimize delivery risk in the event of supply chain disruptions.
Industry pitfalls: Small producers experience 8-12 week order delays according to the 2024 AMI Packaging Survey.
✔Torise's Advantages:
●50,000 square meter factory with annual production of 50,000 tons.
●Reserve inventory for emergency orders (e.g., TRBF96 for produce bags).
Customization & Technical Agility
Why it matters: Applications ranging from compostable mailing bags (high strength) to stretch wrap (custom colors) require customized formulations.
Traps: 68% of buyers say “one-size-fits-all” resins increase processing costs (2023 PCI Wood Report).
✔Torise's Approach:
●Adjust PBAT/PLA/starch ratios to achieve the best price/performance ratio (e.g., TRBF90 for affordable trash bags).
●Free sample making + 72-hour technical support.
Total Cost of Ownership (TCO): Beyond Unit Price
Why it matters: Hidden costs from high scrap rates (e.g., 15%+ for unstable resins) erode savings.
Traps: Low-cost suppliers often omit key additives, resulting in increased molding defects.
✔Torise's Value:
●Guaranteed low scrap rates by controlling formulation ratios.
●Volume order discounts + dedicated account management.
Case Studies
✅ Success: A European retailer reduced compliance costs by 22% using Torise’s EN13432-certified resins for compostable produce packaging.
❌ Failure: An Asian exporter lost $2.3 million due to customs rejection of packaging "lacking BPI".
