Malodour Counteracting Composition for Recycled Plastic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Recycled plastic materials often exhibit malodours due to chemical compounds formed during the recycling process, making them less suitable for packaging consumer products and beverages, as these odours can be intense and have low detection thresholds, thus requiring effective malodour counteracting technologies.
Innovation Solution
A malodour counteracting composition comprising specific compounds such as undecanal, dodecanal, and their derivatives is added to recycled plastic materials to reduce or eliminate malodour perception, which can be incorporated into the plastic during manufacturing or applied as a coating, effectively masking the unpleasant smells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If recycled plastic materials are used for packaging, then environmental sustainability and cost-effectiveness are improved, but malodours are generated that reduce customer acceptance
Solution Approach 1:
The patent introduces a malodour counteracting composition as an intermediary substance that interacts with malodour compounds in recycled plastic materials. This composition contains specific compounds (such as cyclodextrins, enzymes, or masking agents) that bind to, degrade, or mask the malodour-causing compounds, thereby reducing the harmful olfactory effect while preserving the benefits of using recycled plastic for packaging
Solution Approach 2:
The patent transforms the harmful malodour compounds present in recycled plastic materials into beneficial or neutral substances through chemical treatment. By applying specific treatments during or after recycling, the malodour compounds are converted into compounds that do not produce unpleasant odours, thereby turning a disadvantage of recycled plastic into an acceptable or even advantageous property
2Object-generated harmful factors
If malodour counteracting technologies are applied to recycled plastic materials, then customer acceptance is improved, but process complexity increases
Solution Approach 1:
The patent applies malodour counteracting treatment during the recycling process itself, before the recycled plastic materials are finalized for packaging use. By incorporating the malodour removal step early in the recycling workflow, the treatment becomes an integrated part of the manufacturing process rather than a separate post-processing step, thereby reducing overall process complexity
Solution Approach 2:
The patent employs malodour counteracting compositions with specific physical or chemical parameters optimized for effective malodour removal. By carefully selecting and controlling parameters such as concentration, temperature, pH, or treatment time, the patent achieves efficient malodour reduction with minimal additional process steps, thereby balancing effectiveness with process simplicity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The malodour counteracting composition significantly decreases the perception of malodours in recycled plastic materials, bringing the odor impression closer to that of virgin plastic, enhancing customer acceptance and usability.
