With increasing environmental awareness, as a biodegradable solutions provider, we understand that “environmental protection” carries the weight of consumer trust and ecological responsibility. Products labeled “pseudo-degradable” often confuse consumers and pose a serious challenge to trustworthy businesses. How can we ensure product quality and build a reliable environmental brand in such an environment? The following are our practices and reflections.

I. Raw Material Traceability: Establishing High Quality from the Source

We have established a strict raw material traceability system, ensuring raw material quality through a four-tier supplier audit mechanism. All suppliers are required to pass qualification certification, sample testing, production site audits, and continuous performance evaluations. We strictly monitor key indicators such as bio-based content ≥85% and heavy metal limits, and use carbon-14 dating to verify the traceability and safety of raw materials. Details are as follows:

1. Establishing a Four-Tier Supplier Management System:

(1) Qualification Verification: Comprehensive review of supplier qualification documents, requiring complete environmental certification system proof and quality testing reports.

(2) Sample Testing: Laboratory analysis is conducted on each batch of materials to ensure compliance with biodegradable characteristics.

(3) On-site audit: Regularly conduct on-site audits of raw material production bases to ensure that the production process meets environmental protection standards.

(4) Dynamic management: Establish a supplier performance evaluation system and implement a quarterly assessment and merit-based elimination mechanism.

2. Precise control standards for key raw material indicators:

(1) Ensure bio-based content ≥85% (verified through carbon-14 testing).

(2) Strictly control heavy metal content to meet the limits of EU EN13432 standards.

(3) Establish a comprehensive raw material traceability system to ensure the traceability and sustainability of raw material sources.

II. Standardization and Refinement of the Production Process

We have always adhered to the dual production philosophy of standardization and refinement, implementing a strict industry standard system. Production temperature control accuracy reaches ±1.5℃, thickness uniformity error is controlled within 8%, and a complete production batch file is established. Simultaneously, an intelligent quality monitoring system will be introduced to achieve real-time monitoring of process parameters, automatic data analysis, immediate early warning of anomalies, and full-process quality traceability, ensuring the excellent quality of every product. Therefore, in the production process, we implement stricter requirements than industry standards:

1. Establish strict industry standard specifications

(1) Temperature control accuracy reaches ±1.5℃

(2) Thickness uniformity error is controlled within 8%

(3) Establish production batch archives, with a retention period of no less than 2 years

2. Introduce an intelligent quality monitoring system

(1) Real-time monitoring of key process parameters

(2) Automatic collection and analysis of production data

(3) Immediate early warning of quality anomalies

(4) Full-process quality traceability

III. Testing, Verification, and Certification Assurance

We have established a full-process testing system from raw materials to finished products, strictly implementing triple testing standards for physical properties, degradation properties, and safety properties. All products have passed international authoritative certifications such as ASTM D6400 and EN13432, and are regularly reviewed by third-party institutions to ensure that every environmental indicator is verifiable and traceable, providing consumers with genuine and reliable quality assurance.

1. Three-tier testing system and performance certification

(1) Three-tier testing system

Incoming material inspection: Comprehensive testing of raw materials before warehousing

In-process sampling inspection: Hourly sampling inspection during production

Finished product full inspection: 100% of each batch of products passes basic performance testing

(2) Performance certification

Physical properties: Thickness, tensile strength, elongation at break

Degradation performance: Biodegradation rate, degree of disintegration

Ecological safety: Heavy metal content, phytotoxicity

Usage performance: Leakage prevention, load-bearing capacity

2. Certification guarantee: Authoritative endorsement from third-party verification

(1) ASTM D6400 (American Society for Testing and Materials standard)

(2) EN13432 (European Union compostable standard)

(3) OK compost INDUSTRIAL (Belgian certification)

(4) BPI (Biodegradable Products Institute certification)

IV. Continuous improvement to enhance degradation efficacy and quality

We invest 6% of our revenue in R&D and innovation each year to continuously optimize material formulations and production processes. We also establish a closed-loop customer feedback mechanism to ensure that every suggestion is transformed into specific quality improvement measures, allowing product quality to continuously surpass industry standards through continuous iteration.

1. We invest 6% of our annual revenue in R&D, focusing on:

(1) Development of new biodegradable materials

(2) Optimization of production processes

(3) Innovation in testing methods

(4) Improvement of degradation efficiency

(5) Establishment of a closed-loop customer feedback mechanism

2. Establishment of a “receive-analyze-improve-verify” mechanism:

(1) 24-hour response to customer inquiries

(2) Completion of problem analysis within 72 hours

(3) Monthly evaluation of improvement effects

V. Conclusion: Quality is the cornerstone of environmental commitment

As a biodegradable solutions provider, we firmly believe that true environmental protection must be built on a reliable quality foundation. From raw material procurement to product delivery, our comprehensive quality management system ensures that every product can withstand inspection. In terms of quality assurance, we promise to always adhere to quality first, maintain transparency in the production process, continuously innovate technologically, and be responsible to every consumer. We believe that only with solid quality can we win the trust of the market and make a real contribution to environmental protection.
