Description

FEDERAL RESEARCH STATEMENT This invention was made with government support under Contract No. 89303321CEM000080 awarded by the U.S. Department of Energy. The government has certain rights in the invention. FIELD This present subject matter relates generally to a functionalized porous material, more particularly, to a porous material functionalized with a synthetic mineral. BACKGROUND In recent years, corporate sustainability initiatives and national environmental initiatives have become increasingly prominent and influential. Notably, the waste management of manufacturing processes has become a growing concern as manufacturers adjust their processes to better respond to environmental concerns of the manufacturer itself, the public, and administrative or governmental entities. Particularly, the waste management of glass has become a growing concern in modern times. Indeed, it is estimated that over four million tons of waste glass are disposed of in landfills in the United States each year. As such, various corporate sustainability initiatives have focused on processes involving waste glass material. However, recycling waste glass into practical and serviceable products has proven to be challenging. Various different types of materials are utilized in filtration processes. Indeed, filtration devices including activated carbon, activated alumina, polymers, minerals, and/or metals have traditionally been used to filter process streams having contaminants and/or undesirable components. Generally, the type of filtration materials used depends on the targeted contaminants or undesirable components of the respective process streams. Generally, porous materials have been utilized to filter or treat process streams having contaminants and/or undesirable components. However, many porous materials, particularly functionalized porous materials, are often cost-intensive, have limited efficacy, and/or have poor performance. Thus, there is a need for an improved functionalized porous material, particularly a functionalized porous material formed from recycled materials, and related methods.
