Sand for concrete and asphalt are the core construction products from Hydrothermal Carbonization and tumbling the Hydrochar.
The world is running out of sand.
Worldwide, we go through 50 billion tons of sand every year. That is twice the amount produced by every river in the world.
After air and water, sand is our most used natural resource. We use it even more than oil. The major player for sand usage is concrete. The concrete required to build a house takes on average 200 tons of sand, a hospital uses 3,000 tons of sand, and a mile of a highway requires 15,000 tons of sand. PLUS: It’s used to make food, wine, toothpaste, glass, computer chips, breast implants, cosmetics, paper, paint, plastics.
The sand that we use, is called “marine sand.” It is the sand that found at the bottom of rivers, and on beaches and at the bottom of lakes and oceans. We can’t use sand from the desert. Wind erosion makes the grains too round for most purposes. We need angular sand that interlocks like pieces to a puzzle. Like the sand generated from mountain rocks, pelted by rain, wind, and rivers for over 25 thousand years.
The Solution: Hydrothermal Carbonization (HTC) converts the readily available food waste, sewage waste, and animal manure and converts it into Hydrochar, which is then tumbled into sand. In addition to proving the world with needed sand, this HTC process has the very positive environmental results of reducing the adverse impact on reverbed ecology from mining sand and the sequestration of CO2e. Given that the biowaste HTC sand is buried in materials like concrete and roads the biowaste does not emitting greenhouse gases though the biodegradation process. We “capture” the Co2e before it gets into the air.
