Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current agricultural systems face challenges in meeting the increasing global demand for food production while reducing environmental impact and resource consumption, with a need for sustainable and cost-effective alternatives to traditional fossil hydrocarbon-based inputs, and there is a lack of efficient methods to convert CO2 and other greenhouse gases into valuable organic nutrients and fertilizers.
Innovation Solution
The use of naturally occurring or engineered microorganisms that convert CO2, syngas, and methane into high-value organic compounds like amino acids, proteins, and vitamins through chemoautotrophic processes, utilizing gaseous substrates as carbon and energy sources, and integrating these organisms into bioreactors with renewable energy sources for large-scale production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional photosynthetic agricultural systems are used to meet global food demand, then food production increases, but greenhouse gas emissions and resource consumption increase
Solution Approach 1:
The patent converts harmful greenhouse gases (CO2, CH4, N2O) into beneficial organic nutrients through microbial conversion processes. Microorganisms transform these waste gases into amino acids, proteins, vitamins, and other valuable compounds that serve as fertilizers and animal feed, thereby eliminating harmful emissions while creating useful products.
Solution Approach 2:
The patent changes the chemical state of carbon from inorganic gaseous forms (CO2, CH4) to organic compounds (amino acids, proteins, carbohydrates). This transformation involves altering the chemical parameters of carbon fixation through microbial metabolic pathways, enabling the conversion of simple gases into complex bioproducts.
2Productivity
If fossil hydrocarbon inputs are used for food production, then agricultural productivity is maintained, but cost and environmental impact increase
Solution Approach 1:
The patent utilizes inexpensive and readily available gaseous substrates (CO2 from flue gases, CH4 from biogas, N2O from livestock waste) as feedstocks for microbial conversion. These waste gases, which would otherwise be discarded or require expensive disposal, are transformed into valuable nutrients, replacing the need for expensive fossil hydrocarbon inputs.
Solution Approach 2:
The system employs self-sustaining microbial communities that convert waste gases into nutrients autonomously. The microorganisms utilize their own metabolic processes to transform input gases into organic compounds, eliminating the need for complex external energy inputs or expensive synthetic fertilizer production processes.
3Object-generated harmful factors
If CO2 and other greenhouse gases are converted to organic nutrients through microbial processes, then greenhouse gas emissions are reduced, but production scalability and cost-effectiveness are challenges
Solution Approach 1:
The patent employs a multi-functional microbial system capable of converting multiple types of gaseous substrates (CO2, CH4, N2O, H2S) into various organic nutrients (amino acids, proteins, vitamins, carbohydrates). This universal conversion capability allows the system to handle diverse waste gas streams and produce a broad spectrum of valuable products, enhancing scalability and economic viability.
Solution Approach 2:
The patent integrates multiple microbial conversion processes into a unified system that simultaneously transforms different greenhouse gases into organic nutrients. By combining CO2 fixation, methanotrophy, and other microbial conversion pathways in a coordinated bioprocess, the system achieves synergistic effects that enhance overall productivity and scalability.
