Aditya Birla Chemicals’ Advanced Materials business and Tamil Nadu-based Shree Renga Polyester Private Limited have joined hands to develop sustainable solutions for recycling composite waste, in a move aimed at building a more circular composites industry.
The two companies have signed a Memorandum of Understanding (MoU) to develop a recycling ecosystem that combines Aditya Birla’s expertise in advanced epoxy technologies with Shree Renga’s capabilities in recovering and repurposing composite waste.
Composite materials are widely used in wind energy, transportation, construction, aerospace and industrial manufacturing because of their strength, durability and light weight. But their permanent chemical structure makes conventional thermoset composites difficult to recycle at the end of their useful life.
As a result, composite waste is often sent to landfills or incinerated, creating environmental challenges.
The companies said the partnership will focus on addressing this problem through Aditya Birla’s proprietary Recyclamine epoxy system, which enables composites to be selectively broken down during recycling, allowing valuable reinforcing components to be recovered.
The collaboration with Shree Renga is intended to take this technology beyond material recovery and develop commercially viable recycling pathways for composite waste. The companies aim to establish a setup focused on material recovery, resource efficiency and the broader transition towards a circular economy.
“Building a truly circular composites industry requires a value-chain approach, where recyclability is considered from the very beginning. With Recyclamine, manufacturers can design composites with end-of-life recovery in mind, embedding circularity into the material itself. In collaboration with Shree Renga, we are working to create scalable, integrated recycling ecosystems that enable composite waste to be recovered and transformed into valuable resources.” said Rajesh Balakrishnan, Chief Executive Officer, Advanced Materials, Aditya Birla Group.
Sankar K Chairman, Sree Renga Polymers Limited, said, “Making composite recycling work at scale requires more than the right technology; it requires commercially viable solutions that connect material recovery with real-world applications.
"Our collaboration with Aditya Birla combines Recyclamine's ability to recover valuable raw materials with Shree Renga’s expertise in developing and commercialising waste-repurposing solutions. Together, we are building practical recycling pathways that can turn composite waste into useful resources and accelerate the transition towards a more circular composites industry.”
SRPPL says its approach treats recycling as a materials-science challenge rather than simply a waste-management exercise, with its research team working across polymer chemistry, process engineering, additive development and masterbatch development.
