TACC and CGT Unite to Drive Graphene Revolution

TACC Limited , a wholly owned subsidiary of HEG Limited and part of the LNJ Bhilwara Group, has signed a Technical Collaboration Agreement with Ceylon Graphene Technologies (CGT) , a subsidiary of LOLC Holdings PLC and a global pioneer in graphene technologies, to jointly accelerate the commercialization and large-scale adoption of graphene and its derivatives.

Under this collaboration, CGT will bring its decade long expertise in graphene, technology scaleup, and application development to support TACC in building state-of-the-art graphene production capabilities . In turn, TACC will leverage its deep-rooted understanding of graphite technology and carbon science, alongside proprietary process for graphene synthesis and expertise in application-based derivatives, to accelerate innovation and deliver cutting-edge material solutions.

The partnership also unites two strong legacies, and diverse business conglomerates the LNJ Bhilwara Group and the LOLC Group paving way for a secured foundation and a well guided path towards innovation and growth.

TACC’s ongoing collaborations across sectors already provide clear demonstrations of this promise. In construction, TACC is working with the National Council for Cement and Building Materials (NCB) and the Central Road Research Institute (CRRI) on graphene-based concrete solutions. In textiles, TACC has partnered with Birla Cellulose (a division of Grasim Industries) and RSWM Limited to advance the use of graphene in fabric innovation. These initiatives serve as strong citations of TACC’s commitment to powering the future with graphene.

By combining their complementary expertise, TACC and CGT aim to unlock the true potential of graphene, a material hailed as revolutionary for its versatility and performance. The collaboration is expected to drive transformative advancements across multiple sectors, including construction, textiles, coatings, rubber, energy storage and beyond, positioning India at the forefront of next-generation material science.

Under this agreement, TACC and CGT will together:

• Collaborate on engineering design, production scale-up, commissioning, and product validation.

• Undertake feasibility studies and risk mitigation planning with emphasis on commercial viability and environmental compliance.

• Accelerate product trials, validation, and commercialization of graphene-based technologies through shared technical expertise and data.
