Redone Bricks: An Innovative Low-Carbon, Lightweight Construction Material Synthesized from Industrial and Organic Waste

Redone Bricks are a novel, sustainable construction material engineered to address the urgent needfor low-carbon alternatives in the building industry. Developed from a mix of quick lime, C&D waste, plasticwaste, fly ash, aluminium powder, agricultural waste, and Indian Bedellium (Guggul), these bricks are designedto outperform conventional materials in both environmental impact and mechanical properties. A comparativestudy was conducted against six alternatives: Stabilized Mud Blocks (SMBs), Conventional Clay Bricks, Fly AshBricks, Autoclaved Aerated Concrete (AAC) Bricks, Fiber-Reinforced Composite (FRC) Bricks, and Plastic Bricks.Redone Bricks demonstrated superior performance with low weight (1.2 lbs), excellent thermal insulation (2–2.5 m²•K/W), reduced water absorption (20%), and high compressive strength (4.3 N/m²). Priced affordably atINR 8 per unit, they offer economic as well as environmental benefits. Critically, Redone Bricks exhibit aremarkably low CO₂ emission of just 0.00206 kg/kg, representing a >99% reduction compared to conventionalmaterials: Fired Clay Bricks (0.335 kg/kg), AAC Blocks (0.23 kg/kg), SMBs and Plastic Bricks (0.48 kg/kg), andeven Fly Ash Bricks (0.0228 kg/kg). This positions Redone Bricks as the most environmentally friendly option inthe study. Overall, Redone Bricks offer a better path toward greener construction, combining sustainability,performance, and affordability—making them an ideal solution for climate-resilient infrastructure.
