Solution Overview
Problem
The palm oil supply chain faces challenges in tracing the origin of palm oil products due to limitations in current tracking technologies, which are prone to fraud, costly, and exclude small holders, leading to environmental and social concerns.
Innovation Solution
Implementing a DNA barcode system that uses unique DNA taggants applied to products at the harvest site, combined with satellite imaging and blockchain technology to create a secure digital ledger, enabling real-time source assurance and traceability throughout the supply chain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional tracking technologies are used to trace product origin, then traceability is provided, but the system is prone to fraud and costly
Solution Approach 1:
The patent replaces conventional mechanical tracking systems (barcodes, RFID tags, manual documentation) with a biological DNA-based tracking system. DNA taggants are applied to products at the harvest site and can be detected throughout the supply chain, providing fraud-resistant traceability that is inherently more reliable than mechanical systems while reducing overall system complexity through biological universality.
Solution Approach 2:
The patent changes the fundamental parameter of product identification from mechanical/optical properties (barcodes, colors) to biological properties (DNA sequences). This parameter change enables more reliable tracking because DNA is inherently difficult to counterfeit and can be detected with high precision, thereby improving traceability reliability while reducing susceptibility to fraud.
2Measurement precision
If comprehensive tracking systems are implemented, then traceability is improved, but small holders are excluded due to cost
Solution Approach 1:
The patent employs disposable DNA taggant applications that can be applied directly to products at the harvest site using simple processes. The DNA taggants themselves are inexpensive biological materials that can be applied once and then serve their purpose throughout the supply chain, making high-precision tracking accessible even to small holders without requiring expensive reusable infrastructure.
Solution Approach 2:
The DNA-based tracking system enables products to essentially track themselves through the supply chain. The DNA taggants are applied once at the origin and then passively provide identification information at each subsequent stage without requiring active participation or investment from small holders, thereby reducing implementation barriers while maintaining high identification precision.
3Reliability
If DNA taggants are applied to track products through supply chain, then traceability and fraud prevention are improved, but the system complexity increases
Solution Approach 1:
The patent leverages the universal nature of DNA as a tracking medium. The same DNA-based approach can be applied across different products, industries, and supply chain stages, creating a unified system rather than multiple specialized systems. This universality reduces overall complexity while maintaining high reliability for source assurance across diverse applications.
Solution Approach 2:
The patent introduces DNA taggants as an intermediary between the product and the tracking system. Rather than requiring complex direct tracking infrastructure, the DNA intermediary carries identification information passively through the supply chain, simplifying the overall system architecture while enhancing reliability through the inherent properties of DNA as a stable, detectable, and difficult-to-counterfeit medium.

Function Achieved in This Case
This system provides unparalleled traceability and brand protection, ensuring sustainable sourcing by accurately identifying product origins and preventing adulteration, while being cost-effective and inclusive for small holders.
Implementation Method 1
a first DNA taggant material including at least N unique pieces of DNA is applied to a first batch of the material
Data Source
AI summary
Material in a supply chain is tracked by a method of applying a DNA taggant set to a first batch of the material produced by a first supplier of the material. The DNA taggant set corresponds to a tag string corresponding to the first supplier. The first batch is aggregated with a second batch to create an aggregated lot. A sample is selected from the aggregated lot and tested to determine a DNA taggant set of the sample. After selecting a sample from the aggregated lot, the sample may be labeled with a grade and then placed in a receptacle corresponding to the grade.
