Designing for a Circular Future: Expert Talk Highlights 100% Recyclable Glass in Construction

Ramanagara, 9th April 2026: Highlighting the growing importance of sustainability in modern construction, the Department of Civil Engineering hosted an expert talk on 9th April 2026 titled “Closing the Loop: Designing Glass Products for 100% Recyclability”, delivered by Mr U. Gopinath, Manager - Sustainability at Saint-Gobain. The session offered students valuable insights into the evolving role of sustainable practices within the construction industry.

The talk focused on the industry’s transition from a traditional linear production model to a circular economy, where materials are continuously reused rather than discarded. Emphasising the responsibility of future civil engineers, Mr Gopinath highlighted that sustainability must be embedded at the design stage. He explained how glass, as a material, holds significant potential for closed-loop systems through the effective use of cullet (recycled glass), which can substantially reduce both energy consumption and carbon emissions.

A key aspect of the session was the introduction of Design for Recycling (DfR) principles. Students were encouraged to consider mono-material designs and ensure ease of component separation to address current challenges such as contaminated laminates and complex coatings. The discussion also shed light on emerging technologies, including advanced optical sorting systems, which enhance the efficiency of recycling processes.

Further, Mr Gopinath introduced the concept of “buildings as material banks,” supported by innovations such as digital material passports that enable better tracking and reuse of construction materials. These approaches reflect a broader shift towards sustainable construction practices that prioritise resource efficiency and waste reduction.

The session provided students with a forward-looking perspective on sustainable design and its practical applications in civil engineering. By linking theory with industry practices, the talk underscored the importance of innovation in creating environmentally responsible infrastructure and preparing students to contribute meaningfully to a low-carbon future.
