We hand-picked startups to showcase in this report by filtering for their technology, founding year, location, funding, and other metrics. These emerging building material startups work on solutions ranging from carbon-infused materials and wooden construction modules to residential, commercial, and industrial building materials and cement metakaolins, and geopolymers.

1. Net Zero Concrete Solutions – Cement, Metakaolins & Geopolymers

• Founding Year: 2024
• Location: Kelmscott, Australia

Australian startup Net Zero Concrete Solutions develops eco-friendly cement metakaolins and geopolymers. It leverages amorphous silica from regional mines.

The company’s products, like amorphous silica powders and AmSil, are additive mixtures for concrete. They increase water retention and resistance to chemical or environmental stressors. Its colloidal silica, FlowSil, fills in micro-pores of concrete for reducing permeability. This enhances the strength and durability of concrete.

Another product, SForm, is a modular, reusable formwork for sustainable concrete production. It reduces waste associated with single-use formwork. This way, the startup’s solutions serve as eco-conscious alternatives to traditional cement.

2. Carbon Infuse – Carbon-Infused Materials

• Founding Year: 2023
• Location: New York City, USA

USA-based startup Carbon Infuse offers carbon capture, utilization, and storage in construction. It utilizes carbon dioxide mineralization and upcycling of municipal and industrial waste.

The produced CO2-sequestering minerals work as low-carbon concrete. These serve as supplementary cementitious materials for large-scale construction applications.

3. EcoStruct – AI-driven Concrete Optimization

• Founding Year: 2023
• Location: Abbotsford, Canada

Canadian startup EcoStruct provides a platform to optimize concrete mix. It leverages AI to refine ready-mix concrete formulations. AI analyzes and adjusts the proportions of cementitious materials, aggregates, and admixtures to reduce cement usage and carbon emissions.

Besides the platform, the startup develops nano core-shell self-healing and geopolymer concrete. These products utilize industrial by-products, like waste bottle glass and iron ore tailings, respectively. This further supports the circular economy in the construction industry.

4. Crayon – Textile Waste-derived Materials

• Founding Year: 2024
• Location: Seoul, South Korea

South Korean startup Crayon upcycles discarded clothes to create sustainable building materials. Its Unica tile offers custom colors suited for diverse applications. This solution promotes circular practices and prevents incineration and landfill waste.

5. Stelcor – Residential, Commercial & Industrial Building Materials

• Founding Year: 2025
• Location: Ladyville, Belize

Based out of Belize, Stelcor is a startup that offers building materials for residential, commercial, and industrial purposes. Its insulated concrete form blocks possess high R-value insulation for energy-efficient construction.

The ICF improves resistance to natural disasters, fire, moisture, and insects. Its interlocking modular design eases installation and provides a flexible alternative to traditional concrete and wood-frame construction.

The company’s inverted T-beam flooring reduces cracking and porosity of concrete. This enhances load-bearing capacity and structural strength. It also protects against damaging agents like salts, chemicals, and external pollutants.

Further, the startup’s AQURON is a concrete preservation catalyzed colloidal silica solution. It is a water-based sealer that leverages deep penetration technology to absorb into concrete and masonry surfaces. This prevents moisture-related oxidation, cracks, and shrinkage.

6. Foldcast – Paper-based Concrete

• Founding Year: 2024
• Location: Lugano, Switzerland

Swiss startup Foldcast Eco Lumber offers paper-based molds to create concrete structural components. It utilizes recyclable paper formwork and digital fabrication software to offer an automated and scalable production.

Prefabricated structures like SlabX and Vertebra enable rapid deployment at construction sites. This cuts down project times and labor expenses. It also allows architects, engineers, general contractors, and real estate developers to achieve their design and ecological objectives.

7. Sargassum Eco Lumber – Sargassum Repurposing

• Founding Year: 2023
• Location: Homestead, Florida, USA

USA-based startup Sargassum Eco Lumber converts coastal waste into eco-friendly lumber. It collects medium-density polyethylene (MDPE) plastic and excess sargassum from beaches or the sea.

It dries the seaweed waste using a conveyor belt machine equipped with parabolic solar heaters. It heats and shreds the MDPE waste from supermarket bags, packaging, and more. The company then combines these wastes and processes them to produce synthetic wood sheets.

The resulting material is insulating, water-resistant, and non-flammable. This way, the startup converts waste into circular building materials. The solution addresses marine debris pollution threatening sea ecosystems.

8. Timber One – Wooden Construction Modules

• Founding Year: 2024
• Location: Stuttgart, Germany
