GeoBM Construction Ltd
GBM produces building blocks and biomaterials by combining crushed waste materials with non-pathogenic bacteria that generate calcium carbonate, binding waste particles into solid products. The process achieves at least 80% CO2 savings compared to traditional concrete and produces infinitely recyclable materials with compressive strength exceeding 30 MPa for construction waste.

Problem
Global CO2 emissions total approximately 42.2 billion tons per year, and concrete production is a major contributor—if concrete were a country, it would be the world's third-largest emitter of greenhouse gases. Meanwhile, vast quantities of waste materials sit unused in landfills, representing an untapped resource for mitigating emissions and addressing raw material shortages.
Solution
GBM produces building blocks and biomaterials by combining crushed waste materials with non-pathogenic bacteria and nutrients in molds, where the bacteria generate calcium carbonate—the same material found in corals and seashells—that binds waste particles together. The process takes 7 to 28 days depending on desired hardness, requires minimal energy input beyond mixing and drying at moderate temperatures, and achieves at least 80% CO2 savings compared to traditional concrete. The resulting products are crushable and infinitely recyclable, with only about 5% new waste needed per recycling cycle. GBM's technology applies to diverse waste streams including construction debris, wood, clay, sand, glass, and even surgical mask material, and can produce items ranging from tiles and bricks to complex structures like houses.
Target Audience
Primary customers include construction and infrastructure companies seeking sustainable ground stabilization, foundations for buildings, roads, and railways, as well as environmental remediation firms addressing heavy metal leachability in polluted soil and water.
