This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,698.

Summary of the Inventive Concept

A novel application of silicate-based materials with porous structures and metal cations for environmental remediation, extending the core technology of bone graft substitutes to address pollution and contamination in water, air, and soil.

Background and Problem Solved

The original bone graft system patent (PCT/GB2016/052221) was limited to medical applications. However, the silicate-based material's unique properties make it an ideal candidate for addressing environmental pollution. The new inventive concept tackles the pressing issues of water contamination, air pollution, and soil degradation, providing a sustainable solution for industries and communities affected by these problems.

Detailed Description of the Inventive Concept

The silicate-based material's porous structure and metal cations enable it to absorb and neutralize pollutants in water, air, and soil. The material can be tailored to address specific contaminants, such as heavy metals, toxic chemicals, or radioactive isotopes. The system can be designed for various applications, including water filtration, industrial wastewater purification, air purification, and soil remediation. The bioactive properties of the material ensure its effectiveness in neutralizing pollutants, making it a valuable tool for environmental remediation.

Novelty and Inventive Step

The new claims introduce a paradigm shift in the application of silicate-based materials, moving from medical implants to environmental remediation. The inventive step lies in the recognition of the material's potential for pollution mitigation and the development of systems and methods that harness this potential.

Alternative Embodiments and Variations

Alternative embodiments could include using different metal cations, varying the porosity and structure of the material, or integrating the material with other technologies for enhanced remediation capabilities. Variations could also include adapting the material for specific industries, such as agriculture or construction, or developing portable or modular systems for on-site remediation.

Potential Commercial Applications and Market

The silicate-based material for environmental remediation has vast commercial potential, targeting industries such as water treatment, industrial manufacturing, air quality management, and environmental consulting. The market demand for sustainable and effective pollution mitigation solutions is growing, and this inventive concept is well-positioned to capitalize on this trend.
