Funding and Support From
Our mission is supported by a strong network of grants and venture funding partners partnering with us to make concrete carbon negative.
Bioaggregates
Bioaggregates from plant-based fibers are vital for sustainable construction. They offer:
Nature's Carbon Sink
Plant matter is ~50% biogenically stored carbon in the form of cellulose, lignin, and hemicellulose.
Waste Reduction
Utilize feedstocks from existing operations to promote a circular economy.
Energy Efficiency
Lower energy demand than crushed sand, and shorter freight distances compared to natural sand deposits.
Improved Insulation
Enhance thermal and acoustic properties of concrete.
Reduced Weight
Lightweight bioaggregate reduces weight by up to 33%, limiting freight costs + faster installation times.
Addressing the Sand Shortage Issue
1
Alternative to Sand
Bioaggregates reduce dependency on diminishing natural sand resources.
2
Renewable Resource
Plants for bioaggregates are renewable and can be harvested annually.
3
Environmental Preservation
Using bioaggregates lessens the environmental damage from sand mining.
4
Local Sourcing
Bioaggregates can be sourced locally, reducing transportation costs and emissions.
The ClearWash™ Advantage
The ClearWash™ process is a game-changer in sustainable construction. By optimizing the supply chain, this innovative process not only enhances the performance of our concrete blocks but also contributes to significant carbon storage. The ClearWash™ method ensures that each block is manufactured with minimal environmental impact, maximizing the use of renewable resources while maintaining top-tier quality.
- Supply Chain Optimization: Feedstocks are sourced from common waste streams including forest thinning, secondary lumber, agriculture residues, or perennial grasses.
- Carbon Storage: Depending on the feedstock, anywhere from 40-60% of the mass is biogenically stored carbon in the form of cellulose, lignin, and hemicellulose. Entombing this material in concrete ensures that the physical carbon does not decompose back into atmospheric CO2.
- Increased Performance: Our water-based process removes detrimental sugars which enhance compressive strength, decrease cure times, improve freeze-thaw, reduce water demand in cement slurries, and sterilize any inherent mold/fungus.
Clearwash has a patented sizing system capable of tailoring the bioaggregates particle size, morphology, density, and surface chemistry to seamlessly integrate within each unique application.
Concrete Blocks with Reduced Embodied Carbon
Building Code Compliant and Proven Performance
Discover our range of concrete blocks, designed for reduced embodied carbon while meeting stringent building code standards. Stonefiber blocks include ASTM C90 compliant structural grey block, and architectural fence block in 4, 6, and 8 inch variations. Fence blocks can be delivered with a variety of color and finishes including ground face, precision, split, and shot blast. Each block is up to 33% lighter for improved handling during installation, and reduced freight costs to the job site.
DTE Stonefiber blocks have passed ASTM C90 for density, compressive strength, absorption, and fire.
