Solution Overview
Problem
Carbon dioxide (CO2) emissions contribute significantly to global warming and ocean acidification, necessitating effective sequestration methods to mitigate climate change and environmental hazards.
Innovation Solution
Development of non-cementitious compositions incorporating CO2 sequestering additives, such as carbonate compounds precipitated from alkaline-earth-metal-containing water, which can be derived from industrial waste streams, integrated into various products like paper, polymers, lubricants, adhesives, and personal care items, to store CO2 in a stable form.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If CO2 is sequestered using traditional cementitious methods, then CO2 storage capacity is achieved, but environmental harm and carbon footprint increase due to cement production emissions
Solution Approach 1:
The patent converts CO2, a harmful greenhouse gas, into beneficial carbonate compounds that serve as sequestering additives. By reacting CO2 with alkaline-earth metals to form stable carbonates, the invention transforms a pollutant into a useful material that can be incorporated into various products, thereby eliminating environmental harm while maintaining CO2 storage capacity
Solution Approach 2:
The invention changes the chemical state of CO2 from gaseous form to solid carbonate compounds through chemical reactions. This parameter change from gas to solid state enables stable long-term storage of CO2 in various product matrices without requiring cementitious materials, thus avoiding the environmental harms associated with cement production
2Duration of action of stationary object
If CO2 sequestering additives are incorporated into diverse products, then CO2 storage duration is extended, but product complexity and manufacturing difficulty increase
Solution Approach 1:
The patent creates a universal CO2 sequestering additive (carbonate compound) that can be incorporated into multiple different product types including paper, polymers, lubricants, adhesives, and personal care products. This single additive formulation serves multiple functions across diverse applications, extending CO2 storage duration without proportionally increasing manufacturing complexity
Solution Approach 2:
The invention segments the CO2 sequestration function from the product matrix by using a distinct additive component. This segmentation allows the CO2 storage function to be independently optimized while maintaining simplicity in product formulation and manufacturing processes across different product types
