Solution Overview
Problem
Current bioremediation technologies are inefficient and costly, often taking years to reduce contaminants in soil and water to acceptable levels, and face challenges with recalcitrant contaminants and environmental harm from existing products.
Innovation Solution
A biocatalyst composition comprising a mixture of microorganisms, surfactants, co-absorbents, and abrasives, designed to be applied in a partially dry form, which can degrade a wide range of contaminants quickly and safely, utilizing readily available industrial and agricultural by-products, and is effective in both soil and water remediation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing cleaning technologies are used, then contaminants can be removed from soil and water, but the process is extremely labor intensive, costly and time consuming
Solution Approach 1:
The biocatalyst composition performs self-service by using living microorganisms that autonomously seek out, attach to, and degrade contaminants without requiring external intervention. The microbes naturally proliferate in the contaminated environment and continue degrading pollutants until they are eliminated, making the system self-sustaining and eliminating the need for continuous human operation or monitoring.
Solution Approach 2:
The invention replaces mechanical cleaning methods (such as excavation, pumping, and chemical treatment) with a biological system. Instead of using heavy equipment, labor-intensive manual cleaning, or complex chemical processes, the patent employs microorganisms that naturally degrade contaminants through metabolic processes, substituting mechanical and chemical systems with a biological alternative that is faster and less labor-intensive.
2Productivity
If enzymes are added to bioremediation products, then contaminant degradation is enhanced, but enzymes only perform within narrowly defined ranges and cease working once contaminants are partially degraded
Solution Approach 1:
The invention merges multiple different microorganism strains into a single composite biocatalyst product. Each strain possesses different enzymatic capabilities and can degrade different types of contaminants. By combining strains with complementary degradation profiles, the product achieves broad-spectrum effectiveness against diverse contaminants including petroleum hydrocarbons, pesticides, herbicides, and industrial chemicals, while maintaining high degradation rates for each specific contaminant type.
3Ease of operation
If liquid bioremediation compositions are used, then application is straightforward, but spill hazards increase and environmental harm potential rises
Solution Approach 1:
The invention changes the physical state parameter of the bioremediation composition from liquid to dry powder form. This parameter change eliminates spill hazards associated with liquid applications, reduces environmental harm potential, and improves safety during handling and storage. The dry powder can be easily applied to contaminated surfaces and will activate upon contact with moisture in the environment or added water, maintaining effectiveness while reducing risks.
4Reliability
If conventional bioremediation methods are used, then some contaminants can be degraded, but recalcitrant contaminants remain and secondary contaminants are produced
Solution Approach 1:
The invention combines multiple microorganism strains with different metabolic pathways and degradation capabilities into a single biocatalyst composition. This synergistic combination allows the system to completely degrade recalcitrant contaminants that would otherwise resist degradation by single strains. The diverse enzymatic toolkit provided by multiple strains ensures complete mineralization of contaminants to harmless end products (CO2, H2O, biomass) rather than producing secondary contaminants or toxic intermediates.
