DTE's core technology, Clearwash, converts previously discarded agriculture and forest waste into valuable bioaggregates for a variety of construction materials products. The go-to-market deployment of these bioaggregates is a set of precast insulating concrete blocks of varying geometries, called Stonefiber. There are bioaggregate concretes commercially available in Europe and Australia. What is unique about our process, is the ability to source these bioaggregates from the abundant and diverse sources of biomass across a variety of geographic and climate type regions.

Existing natural fiber concretes are derived exclusively from industrial hemp or genetics that are purpose-grown for that application. These bioaggregates must be purpose-grown to ensure a high enough porosity of the fibers to achieve certain insulating performance, and to ensure that no mold is present on the aggregates. The Clearwash process enhances the internal porosity of all biomass to 80%, sterilizes all mold present in spent biomass, and removes hemicellulose and pectin sugar derivatives present in all biomass which delay the curing of cement by 30-60 days. To make bioaggregate concrete feasible, and at magnitudes for significant climate impact, we must have the ability to consistently source fibers from the billions of dry tonnes of ag and forestry waste.

DTE Materials addresses concrete product manufacturers' challenges by cutting the embodied carbon in precast concrete products by up to 40%, resulting in a 33% lighter and more efficiently installed construction material. DTE's non-loadbearing blocks, weighing ~10lbs less than traditional CMU, enhance productivity for installers by allowing them to move 1,000 lbs less per day.

Concrete product manufacturers need to solve their decarbonization issues but current solutions do not exist or require a high capital investment. By utilizing DTE's bioaggregates to seamlessly replace sand aggregates, these precast concrete manufacturers are able to decarbonize their products without requiring a change in behavior.
