Banana Fiber Composite Material Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The fibrous stalks of tropical plants, such as banana trees, are often discarded as waste after fruit harvesting, leading to environmental issues, and the processing of these stalks generates banana fiber dust that lacks beneficial use.
Innovation Solution
A system and method for producing bio composite materials by processing banana fibers to separate and dry them, generating banana fiber dust, which is then pelletized and combined with virgin or recycled plastic using a reducer, press, dryer, pelletizer, and mixer to create a composite material retaining the natural strength and appearance of the fibers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If banana stalks are discarded as waste after fruit harvesting, then environmental harm is caused, but no processing cost is incurred
Solution Approach 1:
The patent converts the harmful waste material (banana stalks) into a beneficial composite material by combining processed banana fibers with plastic materials. The stalks that would otherwise harm the environment are transformed into a useful resource for manufacturing composite products, simultaneously eliminating environmental harm and creating economic value.
Solution Approach 2:
The patent implements a recovery system where banana stalks are collected, processed through retting and drying to extract usable fibers, and then incorporated into composite materials. This prevents the stalks from being discarded as waste while recovering their structural value for industrial applications.
2Reliability
If banana fibers are processed to remove water and latex, then usable fibers are obtained, but processing complexity increases
Solution Approach 1:
The patent divides the banana stalk processing into distinct sequential stages: retting (biological decomposition), drying (moisture removal), and fiber extraction. Each stage addresses a specific requirement, making the overall complex process manageable and controllable while ensuring fiber usability.
Solution Approach 2:
The patent uses natural retting processes with microorganisms as an intermediary to break down the stalk structure and separate fibers from non-fiber materials. This biological intermediary simplifies what would otherwise require complex mechanical or chemical processing systems.
3Manufacturing precision
If banana fiber dust is generated during processing, then fiber separation is achieved, but additional waste byproduct is created
Solution Approach 1:
The patent merges the previously discarded fiber dust with plastic materials to create a composite material. Instead of treating dust as waste to be disposed of, it is combined with other materials to produce a new product, eliminating the waste problem while maintaining fiber separation quality.
Solution Approach 2:
The patent creates a composite material by combining banana fiber dust with plastic materials. This composite approach gives new value to the dust byproduct, transforming it from waste into a functional material with specific properties suitable for various applications.
4Loss of substance
If banana fiber dust is combined with plastic materials, then waste utilization is improved, but manufacturing process complexity increases
Solution Approach 1:
The patent controls the composition parameters of the composite material, specifically maintaining banana fiber dust content between 10-50% by weight. By optimizing this parameter range, the patent achieves effective waste utilization while keeping the processing complexity manageable and the material properties predictable.

AI summary
A system and method for producing bio composite materials by mixing pelletized plant fiber dust and virgin or recycled plastic. The system may comprise a reducer, a press, a dryer, a pelletizer, and a mixer. The reducer separates the fibers of the plant material and the press removes liquid from the separated fibers. The dryer further reduces the moisture content of the pressed fibers and generates dust which is extracted by sifting, screening, or another suitable method. The pelletizer compresses and/or treats the fiber dust with solutions, adhesives, or other processes that cause the fiber dust to adhere together. The fiber dust pellets are then mixed with virgin or recycled plastic to produce a bio composite material.
