The "liquid wood" claim is the assertion, carried in the source dossier on Nägele and Pfitzer, that Arboform is a renewable, biodegradable plastic substitute made from lignin and cellulose that can be processed with conventional thermoplastic techniques.
The claim as stated
The dossier presents Arboform as:
- A material derived from renewable plant feedstocks (lignin and cellulose) rather than petroleum.
- Processable like a conventional thermoplastic — moldable and extrudable.
- Environmentally preferable to petroleum-based plastics, with renewability and biodegradability as framing claims.
Evidence status
The dossier supplies no processing parameters, property data, degradation rates, cost figures or independent test results. Where it references patents or press reports, those references act as pointers, not as validated evidence: a patent records that a method was described and claimed, not that it performs as asserted, and press coverage typically repeats the inventor's or institution's framing.
The claim therefore stands as a source assertion attached specifically to Arboform as described by this dossier. It should not be transferred to lignin, cellulose, bioplastics as a class, or any other material.
The naming problem
"Liquid wood" is a marketing-style label. Arboform is a lignin–cellulose composite, not literally liquefied wood. Repeating the name without qualification obscures the material's actual composition.
