Introducing "Model Case 3: Supporting Quality Improvement of Recycled Materials." Products made from recycled market resources often exhibit lower quality compared to those made from virgin materials. As the use of recycled materials increases in the future, it is expected that the quality requirements will also rise, necessitating countermeasures. By utilizing technologies such as investigating the factors contributing to the performance decline of recycled materials, we can identify the causes of quality degradation. If we can avoid or reduce these factors during the collection, sorting, and recycling processes, we can improve the quality of the final products. [Investigation of Factors Contributing to Performance Decline of Recycled Materials] - Resin degradation assessment: Confirmation of molecular weight reduction through molecular weight distribution measurement - Investigation of fracture causes in resin materials: Fracture surface analysis using optical microscopy, SEM, etc. - Evaluation of moldability: Assessment of moldability through melt viscosity, elongation viscosity, etc. *For more details, please refer to the related links or feel free to contact us.

I would like to introduce "Model Case 2: Consideration of the Use and Operation Methods of Recycled Materials." When considering the use of recycled materials, it is necessary to evaluate the physical properties of the materials, so we can propose various physical property tests. In addition to physical property testing, we can handle everything from compounding to specimen preparation, responding to a wide range of requests. By supporting the comparison of strength between virgin materials and recycled materials, as well as examining the recycling conditions that meet quality requirements, we can establish a system that maximizes the effective use of recycled materials. 【Various Evaluations of Recycled Materials】 ■ Comparison of strength between recycled materials and virgin materials: tensile, bending, compression, impact strength, etc. ■ Comparison by mixing ratio of recycled materials: compounding to specimen preparation to physical property testing for each formulation ■ Comparison of physical property values by number of recycling: evaluation of foreign object size, quantity, etc., through image analysis *For more details, please refer to the related links or feel free to contact us.

I would like to introduce "Model Case 1: Examination of Sorting Methods for Resources Collected from the Market." The resources collected for recycling may contain various types of resins, foreign substances, and impurities. To efficiently reprocess these resources into raw materials, it is necessary to appropriately sort them to meet the required quality standards. By utilizing evaluation techniques for recycled plastic resources and fiber length assessment, we can support the establishment of collection and sorting methods that align with specific objectives, resulting in a system that secures raw materials of the desired quality. 【Evaluation of Recycled Plastic Resources】 - Analysis of resin types in collected items: Identification of resin types such as PP, PE, PS, PVC, PET, etc., using FT-IR. - Analysis of the composition of additives: Organic additives, glass fibers, etc. - Evaluation of foreign substances and impurities: Assessment of foreign substance size, quantity, etc., through image analysis. *For more details, please refer to the related links or feel free to contact us.

Our company provides support for various evaluations of the self-design guidelines for designated PET bottles established by the PET Bottle Recycling Promotion Council. According to the guidelines, the PET bottles used must conform to the fundamental standards outlined in the guidelines (e.g., the bottle must be made of pure PET), and if conformity is unclear, an evaluation based on the evaluation criteria is necessary. We are also available for meetings to discuss the process, so please feel free to consult with us. 【Evaluation Items】 ■ Basic Physical Property Evaluation ■ Reusability Suitability Evaluation - Fiber Applications - Sheet Applications - Bottle Applications - BtoB Applications *For more details, please refer to the related links or feel free to contact us.

We conduct various analyses and evaluations regarding recycled resin materials. It is also possible to assess changes in physical properties according to the number of recycling cycles, and we can handle everything from grinding test specimens to molding and testing in a consistent manner. Through various analyses and evaluations, we measure the characteristics and durability of recycled materials and support the consideration of environmentally friendly materials. Additionally, we can analyze the fiber length distribution of samples after recycling and grinding, and we can perform evaluations using our own grinding machines. Moreover, we can qualitatively and quantitatively analyze 12 types of resins, including PE, PP, and PS, in recycled plastics. Since recycled plastics are prone to contamination with foreign materials such as metals and different resins, which can affect product quality, we also conduct foreign material evaluations using various methods. 【Items Handled】 ■ Evaluation of the recyclability of resin materials ■ Grinding treatment of various resin materials ■ Contamination and foreign material evaluation and inspection of recycled materials ■ Fiber length distribution evaluation of recycled materials ■ Composition analysis of mixed resin materials such as recycled plastics *For more details, please download the PDF or feel free to contact us.

Our company conducts odor analysis to investigate the causes of strange odors in resin materials. By measuring polypropylene (PP) pellets with an anise-like odor using HS-GC/MS and analyzing the odor components with the "Aroma Office" database, we can provide data aimed at identifying the cause of the strange odor. Additionally, starting from the odor impression (e.g., anise-like odor), we can perform reverse searches for multiple compounds recorded in the database and confirm their presence on the chromatogram. 【Features】 - Out of the 29 detected component peaks, 18 matched the odor library, with 6 components identified as substances derived from the anise-like odor. - We can also identify trace components buried among the main components (intensity ratio of approximately 1/100) without missing them. *For more details, please download the PDF or feel free to contact us.

Our company has conducted various analyses related to resin materials and has numerous achievements and know-how. Recently, as part of themes related to the environment, developments have been made in the recycling of resin materials and in products that incorporate cellulose into resin materials. We would like to introduce our analysis and evaluation functions that could be useful for such themes. The molecular weight of cellulose is an important indicator for assessing the degree of degradation when recycling cellulose. Regarding recycling evaluation, we have analysis and evaluation items that aim to address various challenges in recycling. We will also be introducing our analysis and evaluation of cellulose at the "Fujinokuni Cellulose Circular Economy International Exhibition" to be held on October 16 and 17.
