Sustainable raw materials

Industrial Hemp

The Farm Bill of 2018, legalized industrial hemp. Over 40 countries globally adopted industrial hemp, and its global market size is expected to grow rapidly at over 20% annually.

Industrial hemp absorbs atmospheric CO₂ twice as fast as a forest. Hemp grows to maturity within 3-4 months compared to decades for trees, making it one of the best CO₂-to-biomass converters because of its rapid growth.

Hemp Hurds

Hemp seeds and oil extracts constitute majority of industrial hemp market. Hemp hurds are processed stalks of industrial hemp, and are the low-value by-products of industrial hemp. In fact, around 80% of total hemp hurds went to animal bedding in 2020.

We utilize hemp hurds as a primary material for a new type of eco-friendly drywall/tile product that embodies atmospheric carbon.

Hydrated Lime

Hydrated lime is calcium hydroxide (Ca(OH)₂). Hydrated lime is made by burning limestone (CaCO₃) at 900°C, significantly lower than for cement clinkers (1300°C). This lower temperature allows 20% less carbon emissions during manufacturing and a lower energy utility cost for production than cement.

Circular Carbon Cycle
of Hydrated Lime

When hydrated lime is mixed with water, it begins re-absorbing CO₂ from the atmosphere to form calcium carbonate (CaCO₃), also known as limestone. This cycle makes hydrated lime nearly carbon neutral, making it a sustainable material.

Fly Ash

Fly ash is a by-product of non-combustible mineral impurities from burning coal in electric power plants.

Fly ash has cementitious properties that can be used as cement alternatives for construction materials.

Pumice Powder

‍Pumice is powdered volcanic glass. Volcanic glass is naturally produced from volcanic activity, and requires minimal mechanical processing that use little energy. These traits make pumice a sustainable material.
