ASTM D7891 Recycling of Plastic Packaging Waste
The ASTM D7891 standard provides a method for the mechanical recycling of post-consumer plastic packaging waste. This service is crucial in ensuring that recycled plastics meet stringent quality requirements and are suitable for converting into new products without compromising on performance or environmental impact.
The process involves several key steps, each meticulously outlined by ASTM D7891 to ensure reliability and consistency:
- Sample Preparation: The waste plastic packaging is first sorted based on type (e.g., polyethylene terephthalate or HDPE). Once sorted, the materials undergo shredding into small particles.
- Purification: To ensure purity, contaminants such as labels and non-plastic materials are removed. This step often involves water washing followed by drying to achieve a consistent particle size.
- Compounding and Extrusion: The recycled plastic is then compounded with additives like antioxidants or colorants before being extruded into pellets suitable for further processing.
- Quality Assurance: Samples from each batch undergo rigorous testing using various analytical methods to verify compliance with the ASTM D7891 standard. These tests include physical property assessments, chemical analysis, and mechanical strength evaluations.
The primary goal of this service is not only to recycle plastic waste but also to ensure that it can be reused efficiently in new applications. By adhering strictly to ASTM D7891 standards, we help prevent environmental degradation caused by improper disposal and promote sustainable practices within the industry.
For quality managers, compliance officers, R&D engineers, and procurement professionals, this service offers critical insights into how recycled plastics can be effectively managed from waste streams back into consumer products. Properly executed recycling processes like those governed by ASTM D7891 help maintain product integrity while reducing resource consumption and carbon footprints.
To summarize, the ASTM D7891 standard plays a pivotal role in advancing circular economy principles within the plastics industry. It ensures that recycled plastic packaging waste meets high-quality standards necessary for successful integration into new products. This service supports organizations aiming to enhance their sustainability credentials through responsible waste management and recycling practices.
