Abstract: Carbon-neutral fuels are produced from aragonite in a solar thermal decomposition process in which the carbon dioxide generated from the aragonite is catalytically converted to methane, ethanol, or Fischer-Tropsch liquids. Advantageously, heat from the aragonite production can be recovered and used in downstream processes to thereby minimize the carbon footprint of the fuel production.

Abstract: Compositions and methods in which aragonite, and especially oolitic aragonite particles are used as infill material in an artificial turf structure or as sub-growth substrate for natural grass. Advantageously, oolitic aragonite particles provide a superior microporous surface for effective water saturation to impart thermal control and environmental compatibility, ammonia neutralization of urine by reducing urea hydrolysis with the free calcium presented in the aragonite particles, aragonite particle uniformity allowing for reduced compaction and desirable water draining, and the microporous oolitic aragonite particles have an evaporative cooling surface.

Abstract: Disclosed herein are personal care and/or cosmetic compositions, comprising a carrier and oolitic aragonite beads having an average diameter between 10 nm to 10 mm. Also disclosed herein are methods of reducing plastic contamination and/or pollution comprising making a cosmetic or personal care composition, wherein at least a portion to all (100%) of the plastic microbeads in the cosmetic or personal care composition are replaced with oolitic aragonite. Also disclosed herein are a milling system and milling methods for producing oolitic aragonite particles having a clean top size in which the particles are screened to remove any oversized particles. Additional uses include drug-loaded aragonite particles for therapeutic drug delivery and chromatography media.

Abstract: Methods and systems for making calcium oxide (CaO), carbon dioxide (CO2) and/or calcium hydroxide (Ca(OH)2) from aragonite, for example, oolitic aragonite, are provided. The method can include applying solar energy, for example, by focusing one or more mirrors in one or more heliostats, to heat a reactant mixture in a vessel. The reactant mixture includes oolitic aragonite and can be heated to a temperature from 500° C. to 950° C. The system can include a vessel and a means for applying solar energy to heat a supply of oolitic aragonite disposed inside the vessel. Methods of converting the CO2 to ethanol, ethylene, graphene, and/or methane are also provided.
