Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Non-recyclable plastics often end up in landfills and the environment, causing significant environmental damage due to ineffective recycling methods and individual behavior challenges.
Innovation Solution
A residential plastic recycling unit with multiple dispensers that spray an enzyme blend, specifically PETase and MHETase derived from Ideonella sakaiensis 201-F6, to break down plastics into environmentally friendly components, combined with temperature control and UV light assistance, facilitating the degradation of plastics into benign monomers within a controlled environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional recycling methods are used, then some plastics can be recycled, but many plastics still end up in landfills and the environment causing significant environmental damage
Solution Approach 1:
The patent replaces traditional mechanical recycling methods with a biological/enzymatic system. Multiple nozzles dispense enzyme blends onto plastic items, and a temperature control device maintains optimal conditions for enzymatic degradation, transforming the plastic into environmentally benign components without mechanical processing
Solution Approach 2:
The patent introduces an enzyme blend as an intermediary substance that facilitates the breakdown of plastic. The enzymes act as a mediator between the plastic waste and the environment, converting harmful plastic into benign components through biochemical reactions rather than direct environmental exposure
2Productivity
If enzyme spray is used to break down plastic, then plastic degradation is achieved, but energy is consumed for temperature control and enzyme dispensing
Solution Approach 1:
The patent controls the temperature parameter within a specific range (20°C to 45°C) to optimize enzymatic activity. The temperature control device maintains this optimal range, and the system can adjust temperature parameters based on the specific plastic type and enzyme requirements to maximize degradation efficiency while minimizing energy consumption
