Read More

Sensytec

Using sensors to optimize concrete mixes, reduce embodied carbon, and minimize testing waste.

Read More

Solid Carbon

Using carbon-negative biochar-based ingredients to transform the built environment into a massive carbon sink, turning concrete from a climate problem into a climate solution.

Read More

SUN METALON

Enabling cost-effective, sustainable metal recycling without the quality degradation of traditional recycling methods.

Read More

Tereform, Inc.

Chemically recycling synthetic textiles—which are made from petrochemicals—with an energy efficient process, diverting materials from landfills and reducing demand for new carbon-intensive materials.

Read More

Theseus Development

Producing sustainable, interlocking concrete blocks without traditional cement, concrete's most emissions-intensive ingredient, to accelerate the transition to a green built environment.

Read More

Urban Mining Industries

Repurposing waste glass into a low-carbon cement replacement that improves concrete durability, impermeability, and mitigation of the urban heat island effect.

Read More

Via Separations

Lowering the embodied carbon of everyday products and materials by replacing thermal separations, a key process to separate substances based on boiling points, with an electrified filtration process.
