Digestate-Based Biodegradable Plant Container for Soil Improvement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plant containers made of synthetic materials are harmful to the environment and do not contribute to soil health, while biologically based alternatives do not improve soil quality or reduce the need for artificial fertilizers.
Innovation Solution
A biodegradable container made from digestate and a cellulose-based binder, produced through a pressing process, which is firm, sturdy, and dissolves into the soil, improving soil structure and reducing the need for artificial fertilizers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If synthetic materials are used for plant containers, then durability and firmness are improved, but environmental harm and soil degradation occur
Solution Approach 1:
The patent changes the material composition parameters from synthetic polymers to biodegradable natural fibers (straw, hay, corn stalks) combined with binders. This parameter change maintains container structural integrity while eliminating environmental harm, as the natural fiber container decomposes harmlessly in the soil after use.
Solution Approach 2:
The patent creates a composite material system combining natural fibers (straw, hay, corn stalks) with binders (starch, cellulose, or natural polymers). This composite approach provides both the durability needed for container function and the biodegradability required for environmental compatibility, resolving the contradiction between strength and environmental harm.
2Object-generated harmful factors
If biologically based materials are used for containers, then environmental harm is reduced, but soil quality improvement is insufficient
Solution Approach 1:
The container is designed to serve dual functions: protecting the plant during growth and then serving as a beneficial soil amendment after use. The biodegradable natural fiber container continuously improves soil quality as it decomposes, providing organic matter and nutrients that enhance soil structure and fertility, thereby the container serves itself by becoming part of the soil ecosystem.
Solution Approach 2:
The patent converts what would normally be waste products (straw, hay, corn stalks) into valuable container material that actively improves soil quality. These agricultural byproducts that would otherwise be discarded are transformed into functional containers that, after use, become soil conditioners, turning potential harm into benefit.
3Duration of action of stationary object
If natural fiber materials are used for containers, then biodegradability is improved, but structural firmness deteriorates
Solution Approach 1:
The patent combines weak but biodegradable natural fibers with binders to create a composite material that achieves both structural firmness and biodegradability. The binder component provides the necessary structural integrity while the natural fiber component ensures biodegradability, allowing the container to maintain strength during use and then decompose after use.
Solution Approach 2:
The patent modifies the physical and chemical parameters of natural fiber materials by combining them with binders and controlling moisture content and compression during manufacturing. These parameter changes enhance the structural firmness of the natural fiber container while preserving its biodegradable nature, resolving the contradiction between durability and environmental compatibility.
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 container enhances soil quality, reduces desiccation, and minimizes environmental harm by dissolving into the soil, providing nutrients and improving soil structure without the need for artificial fertilizers.
Implementation Method 1
the material further comprises an added binder, in an amount of between 0.1 - 8 wt.％ of said binder... the binder is selected from a binder comprising at least one of a cellulose and a cellulose derivative
Implementation Method 2
the container is made of a material, wherein the material comprises at least one of digestate and a product from a manure processing process... which is firm, sturdy, and dissolves into the soil
