Narayan Saboo, Chairman, Bigbloc Construction, discusses the qualities of AAC blocks and its environmentally friendly properties.

What is the composition of Autoclaved Aerated Concrete (AAC) blocks?
AAC is a lightweight, precast, cellular concrete. It is a green building material composed of fly ash, gypsum, lime, portland cement, water and aluminum powder. AAC blocks are made in rectangular prism shape only.

What is the core functionality of the blocks?
AAC blocks are widely used in the construction of apartments and other types of residential properties, industrial and commercial buildings. Owing to their excellent heat insulation capacity and thermal resistance, AAC blocks find application in interior and exterior construction.

What brings strength and durability to these blocks?
These materials include cement, lime, fly ash, gypsum, aluminum powder and some other additives. The precise combination and proportion of these materials contribute to their overall strength.

How do you ensure quality standards?
We make AAC blocks as per BIS code IS 2185 Part 3, guidelines in IS code to ensure quality standards.

What are the key advantages of using these blocks as building materials?
AAC blocks are eco-friendly and sustainable. They are lightweight, thermally insulated, energy efficient and fire resistant. Their other qualities include acoustics performance, easy workability, design flexibility and faster construction. AAC Blocks are one-third in weight as compared to red bricks thereby reducing the dead load on the building and resulting in huge saving of structural costs. Also, as the size is equivalent to almost nine red bricks, construction is much faster; the labour required is less; joints in the wall are also less thereby resulting in mortar savings, too.

How does it impact the environment?
AAC blocks are eco-friendly and sustainable. They are green lightweight building materials, with less transport cost. This material warms the room during the winter and cools it during the summer, reducing air-conditioning system usage by at least 25 per cent. Non-toxic and pest repellent, they prevent soil erosion and consume less water. Use of red bricks results in an upper layer of soil erosion, which makes the land barren or infertile in the long run.

What innovations can we expect from you?
We are starting with the manufacturing of ALC panels, which is further advancement of technology as ALC panels are a new age building material that is a further advancement of AAC Blocks.
Panels are reinforced with steel and they will make construction much faster, too. Also, we are looking to get many other new age building materials in our partnership with SCG.

The Confederation of Indian Industry (CII), through its Green Business Centre and Energy Efficiency Council, inaugurated the 16th Conference on Alternative Fuel and Raw Material Usage (AFR) in Goa on 27 October 2026. The two-day conference brought together more than 350 industry leaders, policymakers, waste management experts and technology providers to explore strategies for accelerating alternative fuel adoption in India’s cement industry.

Held under the theme ‘Preparation for Net-Zero: Alternative Fuels & Raw Material in Cement Manufacturing’, the conference focused on reducing dependence on conventional fuels, improving waste utilisation and strengthening circular economy practices across cement manufacturing operations.

E R Raj Narayanan, Chairman, AFR Conference 2026, and Business Head and Chief Manufacturing Officer, UltraTech Cement, highlighted the industry’s progress in alternative fuel adoption. He emphasised the need to scale implementation, strengthen supply chains and extend circularity beyond fuel substitution to alternative raw materials through technological innovation and industry collaboration.

Harish Adconkar, Managing Director, Goa Waste Management Corporation, highlighted Goa’s progress in scientific waste management and refuse-derived fuel (RDF) production. He stated that approximately 765,000 tonnes of RDF had been supplied to cement plants, contributing to an estimated displacement of 320,000–560,000 tonnes of coal. He emphasised the importance of consistent RDF offtake and stronger coordination between urban local bodies, waste management agencies and cement manufacturers.

Dr L P Singh, Director General, National Council for Cement and Building Materials, identified AFR as an important opportunity for decarbonisation and resource efficiency. Drawing parallels with the industry’s successful utilisation of fly ash, he stressed the need to address quality, technological and economic challenges to expand alternative fuel adoption.

Dr Sharad P Kale, Special Advisor to the Chief Minister of Goa and former Head of Technology Transfer and Collaboration at BARC, emphasised treating waste as a resource. He highlighted decentralised biodegradable waste processing, reduced food waste and improved resource recovery as essential measures for minimising landfill dependence.

Kiran Ananth, Executive Director, Energy Efficiency, Renewable Energy and Green Entrepreneurship, CII-Green Business Centre, noted that India’s cement production reached approximately 491 million tonnes in FY2025-26, while the industry’s thermal substitution rate (TSR) stood at 7.5 per cent, with around 7 million tonnes of alternative fuels utilised annually.

He added that the industry had invested over Rs 12 billion in co-processing infrastructure during the past six years. Improving RDF supply reliability and quality assurance would be crucial to maximising the utilisation of existing infrastructure and accelerating industrial decarbonisation.

The conference also featured discussions on advanced AFR co-processing technologies, waste pre-processing solutions and industrial best practices for improving fuel substitution and resource recovery.

A publication titled ‘From Waste to Kiln: Scaling the Use of MSW-Derived RDF in Indian Cement Plants’ was launched during the inaugural session. The report identified inconsistent RDF supply and quality as major barriers to achieving higher thermal substitution rates.

According to the publication, many cement kilns already possess the technical capability to achieve higher alternative fuel substitution. However, variations in RDF availability, moisture content, particle size and calorific value continue to limit utilisation. The report emphasised the need to strengthen waste segregation, pre-processing and aggregation systems to establish reliable RDF supply chains.

The conference’s second-day agenda includes discussions on innovative domestic and industrial waste management solutions, alternative raw materials for low-carbon cement and strategies to increase alternative fuel utilisation across India’s cement manufacturing sector.
