Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The livestock industry generates significant environmental and health issues due to the accumulation and burning of manure, which produces noxious gases, corrosive substances, and pollutes water and soil, while also contributing substantially to greenhouse gas emissions.
Innovation Solution
A method for treating livestock manure to extract lignin, which involves washing and separating the manure using rotary movements, ultrasound, and water drag, followed by pressing and drying to produce a high-calorific biofuel that minimizes toxic gas emissions and ash production, without the need for chemical or thermal processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If manure is burned directly as fuel, then energy can be obtained, but noxious gases, corrosive substances and toxic emissions are generated
Solution Approach 1:
The patent extracts lignin specifically from manure through washing and separation processes, isolating the beneficial fuel component while removing harmful contaminants. This extraction principle allows obtaining high-calorific fuel material without the associated harmful emissions of direct manure combustion.
Solution Approach 2:
The patent converts the harmful practice of direct manure burning into a beneficial process by separating and utilizing only the lignin component for combustion. The harmful organic matter and contaminants are removed through washing, transforming the originally harmful waste into a clean fuel source that produces minimal emissions.
2Quantity of substance
If manure is accumulated in washing ponds, then storage is achieved, but environmental pollution and health hazards increase
Solution Approach 1:
The patent extracts valuable lignin from accumulated manure through systematic washing and separation, converting the stored waste into useful fuel material. This extraction transforms the environmental burden of manure accumulation into a resource recovery process, eliminating pollution while utilizing the stored material.
Solution Approach 2:
The patent discards the harmful liquid fraction and contaminants from manure while recovering the valuable lignin component for fuel production. This selective recovery process eliminates environmental pollution from manure storage while capturing energy resources, turning waste management into resource recovery.
3Manufacturing precision
If chemical processes are used to treat manure, then purification efficiency increases, but process complexity and cost increase
Solution Approach 1:
The patent replaces complex chemical treatment processes with simple mechanical washing and separation methods. By using water flow, gravity, and physical separation to extract lignin from manure, the process achieves effective purification without requiring sophisticated chemical equipment or complex process control systems.
Solution Approach 2:
The patent employs simple, inexpensive washing equipment and basic separation infrastructure rather than expensive, complex chemical treatment plants. The process uses readily available water and basic mechanical components, making the purification system affordable and accessible while achieving the required separation efficiency.
4Manufacturing precision
If thermal processes or carbonization are applied to manure, then fuel quality improves, but energy consumption and process complexity increase
Solution Approach 1:
The patent replaces energy-intensive thermal processes and carbonization with simple mechanical washing and drying operations. By using water flow for separation and ambient or low-energy drying methods, the process produces high-quality lignin fuel without the high energy consumption associated with thermal treatment or carbonization processes.
