Being aware of material deviations, especially when talking about the use of recyclate material is crucial for the upcoming challenges in plastics manufacturing Thank you Polymer Engineering, University of Bayreuth and the team around Holger Ruckdaeschel to share this great piece of paper that helps molders to look at their current manufacturing processes from a different perspective. Nowadays, assuming prime material is being used, we have experienced people and a gut feeling of how to setup and readapt a process in case of failures. With the additional variation of higher material deviations the existing knowledge on the shopfloor alone will not bring the solution.

The increasing demand for plastics in conjunction with the imperative of a circular economy underlines the growing importance of recycling processes for discarded consumer goods. In this context, reactive processing of recycled polyethylene terephthalate (rPET) with pyromellitic acid dianhydride (PMDA) has emerged as a frequently investigated modification approach. This method aims to improve the viscous and elastic material properties of degraded PET through mechanical recycling. However, despite its widespread use, the kinetics of the underlying chain extension reaction have not yet been thoroughly investigated. In our study, we looked at the kinetic variables of the reaction, taking into account material and process parameters. Understanding these variables is crucial for optimizing the reaction. By utilizing kinetic variables, we obtain valuable indicators that allow us to link changes in process data to corresponding changes in material properties. These insights are crucial for refining and perfecting the reactive processing of rPET with PMDA and contribute to advances in sustainable plastics recycling.

Let's talk about the challenges with rPET ♻️ rPET (recycled polyethylene terephthalate) is often heralded as a sustainable alternative to virgin PET, but its recycling process presents several challenges that need addressing. The Challenge for PET Preform Producers: 🔄 Quality and Cost: Bottling companies demand high-quality PET preforms at low costs but do not perform quality checks themselves, returning defective preforms to producers. This hinders the use of rPET. 🌍 Color Consistency: PET preforms often face color consistency issues due to unstable dye dosing, inefficient color switching, or mixing different batches. 📉 Supply Chain Limitations: The availability of rPET is limited by the efficiency and scale of recycling programs. Inadequate collection and sorting infrastructure can lead to insufficient supply to meet growing demand. 🔋 Energy Use: While rPET reduces the need for new raw materials, the recycling process itself is energy-intensive. Ensuring that this energy comes from renewable sources is crucial for maximizing environmental benefits. At MAVISOL, we are committed to addressing these challenges by improving recycling technologies and processes. By enhancing the quality and efficiency of rPET production, we aim to make this circular solution more viable and impactful.

Did you Know: Common types of plastic waste include PET (Polyethylene Terephthalate) from bottles, HDPE (High-Density Polyethylene) from containers, PVC (Polyvinyl Chloride) from pipes and packaging, LDPE (Low-Density Polyethylene) from bags, PP (Polypropylene) from packaging and utensils, and PS (Polystyrene) from foam products. Managing and recycling these plastics is crucial for reducing environmental impact. #GloPlast

Im thrilled to share that my latest work has been published in Advanced Functional Materials🎉 Click the link below to read more about this paper!

First RecyClass certified paper label for HDPE and PP containers launched UPM Raflatac, a Finnish company, has introduced the world’s first RecyClass certified paper label material compatible with rigid high-density polyethylene (HDPE) and polypropylene (PP) containers. Named New Wave, this label material supports the recycling of home and personal care product containers, such as soap bottles and detergent containers, by washing off cleanly at 40°C with plain water, ensuring no chemical residues. It is currently the only RecyClass-recognized label solution for rigid natural and white PE and PP material streams. Available in EMIA and soon in the Asian market, New Wave is designed to prevent contamination in recycling processes by performing without fibre loss. This innovation helps brands make their entire packaging eligible for RecyClass certification, aligning with evolving regulations like the European Packaging and Packaging Waste Regulation (PPWR).

Polyethylene Low Density (LDPE) is a type of thermoplastic that is widely used in various applications due to its unique combination of properties such as flexibility, transparency, and chemical resistance. A primary driver for the LDPE market is the escalating demand for flexible packaging solutions in the food and beverage industry. LDPE's inherent properties such as moisture resistance, flexibility, and sealability make it an ideal material for manufacturing pouches, wraps, and bags used for packaging food items. 𝐓𝐚𝐤𝐞 𝐚 𝐒𝐚𝐦𝐩𝐥𝐞 𝐂𝐨𝐩𝐲: https://lnkd.in/dh8nxn6M One emerging market opportunity for LDPE lies in the development of advanced recycling technologies and circular economy initiatives. As environmental concerns related to plastic waste continue to escalate, there is a growing emphasis on implementing recycling programs and creating closed-loop systems for plastic materials like LDPE.
