Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for reducing methane emissions from landfills are costly, time-consuming, and inefficient, particularly when dealing with elastomeric articles undergoing anaerobic biodegradation.
Innovation Solution
An eco-friendly wearable article is developed with a nutrient complex comprising anionic sulphate ions and cationic salts of iron(II) and copper(II), which is integrated into the article through a coagulant dipping system. This nutrient complex facilitates in-situ methane oxidation by methanotrophic bacteria during anaerobic biodegradation in landfills.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If traditional vacuum collection systems are installed in landfills to capture methane emissions, then methane capture capability is improved, but device complexity and cost increase significantly
Solution Approach 1:
The invention extracts the methane oxidation function directly into the wearable article itself by incorporating methanotrophic bacteria and nutrients, eliminating the need for external vacuum collection wells and blowers. The article becomes self-sufficient in treating its own methane emissions during biodegradation.
Solution Approach 2:
The wearable article contains embedded nutrients and methanotrophic bacteria that enable it to autonomously oxidize methane emissions during its biodegradation in the landfill, without requiring external collection or treatment infrastructure.
2Object-generated harmful factors
If bioreactors with methanotrophic microorganisms are used to treat landfill gas, then methane oxidation efficiency is improved, but cost and operational complexity increase due to equipment and growth medium requirements
Solution Approach 1:
The invention uses a disposable wearable article that incorporates a limited supply of nutrients and methanotrophic bacteria sufficient for the article's service life. After use, the article is disposed of in the landfill where it continues to function, eliminating the need for expensive, maintainable bioreactor infrastructure.
Solution Approach 2:
The invention extracts the entire bioreactor system (microorganisms, nutrients, and oxidation function) and embeds it directly into the wearable article, eliminating the need for separate bioreactor equipment, growth medium reservoirs, and monitoring systems.
3Object-generated harmful factors
If purified oxygen is provided to achieve aerobic environment for methane oxidation, then methane oxidation rate is improved, but cost and operational complexity increase
Solution Approach 1:
The article leverages the natural landfill environment's existing oxygen availability and incorporates nutrients that enable methanotrophic bacteria to oxidize methane using ambient conditions, eliminating the need for external oxygen supply systems.
4Reliability
If growth culture medium is used to sustain methanotrophic microorganisms, then microorganism activity is improved, but maintenance requirements and operational time increase
Solution Approach 1:
The invention incorporates all necessary nutrients and methanotrophic bacteria into the wearable article during manufacturing, preparing the system in advance to function autonomously during biodegradation without requiring ongoing maintenance or medium replacement.
