Solution Overview
Problem
Current agricultural systems face challenges in meeting the increasing global demand for food production while reducing environmental impact, water consumption, and greenhouse gas emissions, and there is a need for sustainable alternatives to traditional fossil hydrocarbon-based fertilizers and biostimulants that can enhance plant growth and stress tolerance.
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, which are then processed into biostimulants and biofertilizers using bioreactors, leveraging chemoautotrophic microbial processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fossil hydrocarbon-based fertilizers and biostimulants are used, then plant growth and stress tolerance are enhanced, but environmental impact, water consumption, and greenhouse gas emissions increase
Solution Approach 1:
The patent changes the chemical composition parameters of fertilizers by using microbially produced organic compounds (amino acids, proteins, vitamins) instead of traditional inorganic fertilizers, thereby improving plant growth enhancement while reducing environmental harm
Solution Approach 2:
The patent converts CO2 emissions into useful resources by using microorganisms to fix CO2 and produce valuable organic compounds for fertilizers, transforming the harmful greenhouse gas into a beneficial carbon source for plant growth
2Quantity of substance
If photosynthetic systems are used to produce nutrients from CO2, then sustainable nutrient production is achieved, but land use and water consumption increase
Solution Approach 1:
The patent replaces photosynthetic systems with chemoautotrophic microbial systems that use chemical energy to fix CO2, eliminating the need for land-based photosynthesis while maintaining sustainable nutrient production
Solution Approach 2:
The patent concentrates the nutrient production process in microbial cultures rather than requiring large areas of land for photosynthesis, achieving high-density nutrient production in controlled environments
3Quantity of substance
If heterotrophic reactions utilizing fixed carbon feedstocks are used, then nutrient production is achieved, but dependence on photosynthesis and indirect resource consumption increase
Solution Approach 1:
The patent uses CO2 fixation by chemoautotrophic microorganisms to produce nutrients independently of photosynthesis, converting a previously harmful dependency on photosynthetic products into a self-sufficient system that can use CO2 directly
