Recently, I had the opportunity to visit 𝐒𝐡𝐫𝐢𝐝𝐡 𝐈𝐧𝐝𝐮𝐬𝐭𝐫𝐢𝐞𝐬, Chhattisgarh, an established rPET flake manufacturer, to explore a long-term association spanning technical consulting, process optimization, market development, and commercial growth. My discussions with the leadership team — 𝐌𝐫. 𝐑𝐚𝐣𝐞𝐧𝐝𝐫𝐚 𝐏𝐫𝐚𝐬𝐚𝐝 𝐉𝐚𝐢𝐬𝐰𝐚𝐥, 𝐌𝐫𝐬. 𝐊𝐡𝐮𝐬𝐡𝐛𝐮 𝐉𝐚𝐢𝐬𝐰𝐰𝐚𝐥, and 𝐌𝐫. 𝐒𝐡𝐫𝐢𝐝𝐡 𝐉𝐚𝐢𝐬𝐰𝐚𝐥, along with the plant and technical teams — covered the rPET value chain from feedstock quality and process technology to product consistency, downstream applications, and market expansion. Key focus areas included: • rPET flake quality, contamination control & thermal-degradation minimization • Process optimization, productivity, yield and equipment performance • Testing, QA/QC, certification and customer specifications • PET sheet and other high-value rPET applications • Market development and expansion across key polymer-consuming regions • Technical po...

A new type of plastic that turns into a gas when heated and reforms into a solid when cooled has been developed by scientists at the #UniversityofSurrey , opening up a new approach to processing and recycling polymers.  In a study published in Macromolecules, researchers introduce a novel polymer that could simplify how materials are applied, removed and recycled by eliminating several of the complex processing steps used today.  Conventional plastics such as #polyethylene , used in everyday products such as carrier bags, #foodpackaging and shampoo bottles, are persistent and not suitable for #chemicalrecycling . While other chemically recyclable polymers have been developed, they typically require much higher temperatures of around 150–200 degrees Celsius to break down, and the recovered material often needs additional chemical processing before it can be turned back into a #plastic .  The Surrey team's new material is similar to polyethene in that it is soft, insoluble...

Sudarshan Chemical Industries Limited announced that its near-term greenhouse gas emission-reduction targets have been validated by the Science Based Targets initiative ( #SBTi ), the global body that independently assesses corporate climate goals against the latest climate science. The validated targets commit Sudarshan to a 58.8% absolute reduction in Scope 1 and Scope 2 emissions by FY2035, against an FY2025 baseline, in line with a 1.5°C pathway. The company has also committed to extending climate action across its value chain, with suppliers representing 90.8% of emissions from purchased goods and services set to adopt science-based targets of their own by FY2030. Sudarshan will pursue these targets through a combination of operational efficiency and low-carbon energy transition measures. Key levers include improving energy efficiency across manufacturing operations, increasing the share of #renewableelectricity through a range of procurement mechanisms, and shifting towards lowe...

𝐓𝐨𝐝𝐚𝐲'𝐬 𝐊𝐍𝐎𝐖𝐋𝐄𝐃𝐆𝐄 𝐒𝐡𝐚𝐫𝐞 𝗪𝗲𝘁𝘁𝗶𝗻𝗴 𝗔𝗴𝗲𝗻𝘁 𝗼𝗿 𝗟𝗲𝘃𝗲𝗹𝗶𝗻𝗴 𝗔𝗴𝗲𝗻𝘁? 𝗧𝗵𝗲𝘆’𝗿𝗲 𝗡𝗢𝗧 𝘁𝗵𝗲 𝗦𝗮𝗺𝗲. In coating formulation, these two additives are often grouped together as *"wetting & leveling agents. But understanding where and how they work can make the difference between solving a defect—or making it worse. Here's a practical breakdown: 🔹 𝗪𝗲𝘁𝘁𝗶𝗻𝗴 𝗔𝗴𝗲𝗻𝘁𝘀 ✔ Work at the **solid–liquid interface** ✔ Reduce interfacial tension so coatings can spread, penetrate, and adhere ✔ Help eliminate poor substrate wetting, crawling, and incomplete coverage ✔ Especially important for difficult substrates and high-speed coating processes 🔹 𝗟𝗲𝘃𝗲𝗹𝗶𝗻𝗴 𝗔𝗴𝗲𝗻𝘁𝘀 ✔ Work at the **liquid–air interface** ✔ Equalize surface tension across the wet film ✔ Prevent defects such as orange peel, brush marks, craters, and uneven gloss ✔ Deliver smoother appearance and higher DOI after curing 𝗔 𝗰𝗼𝗺𝗺𝗼𝗻 𝗺𝗶𝘀𝗰𝗼𝗻𝗰𝗲𝗽𝘁𝗶...

#Envalior , a global leader in Sustainable & High-Performance Engineering Materials, has announced a Memorandum of Understanding (MoU) with #SECARA , a fast-growing technology scale-up specializing in the development of industrial-scale solutions for closed-loop #polymerrecycling . Through this collaboration agreement, Envalior will work with SECARA to test and validate pathways to incorporate high-quality post-consumer-recycled (PCR) content into technical material grades based on SECARA’s novel #catalyticdepolymerizationprocess . "Circularity is one of the defining shifts facing the automotive industry, and it can only be solved through strong partnerships across the value chain. With SECARA, we want to explore early what a scalable, high-performance circular pathway could look like and ensure Envalior is ready to support our customers as the ELV requirements take place,” says Christophe Cazabeau, EVP Performance Materials at Envalior. Helping automotive players meet End-of-...

Amcor , a global leader in developing and producing responsible #packagingsolutions , has announced the installation of state-of-the-art automated manufacturing lines and vision inspection systems for #healthcarebag production at its Mundelein, Ill. facility. Amcor’s investment demonstrates significant advancements in packaging reliability and safety. Medical product recalls due to sterile barrier breach are commonly connected to packaging seal failures, pin holes and contamination. Amcor’s new state-of-the-art vision systems inspect 100 percent of the bags, including film-to-film and film-to-Tyvek® seals, delivering exceptional confidence in package quality. Production data is serialized to individual bags providing full manufacturing traceability. As part of Amcor’s broad global healthcare packaging network, the Mundelein, Ill. facility delivers robust vertical integration with full control of its blown film, printing, laminating, slitting and converting processes, allowing for opti...
