University of Maine researchers unveil a 3D printed home they claim is first 100% bio-based

University of Maine’s Advanced Structures and Composites Center (ASCC) has recently demonstrated a house that they claim is 100% bio-based and 100% recyclable. There are parts to this claim that seem a little questionable to this writer. For one thing, every modern house is bound to contain communications such as wires and pipes which typically are not made of bio-materials and are not fully recyclable. Same for the glass in window panes and lighting fixtures. But if all the construction elements - including the foundation - are indeed bio-based and recyclable that is still quite impressive. And if the core source material is saw dust that is certainly a major contribution to better ecological management.
This is potentially a breakthrough, pending a successful implementation in the field.

BEER.I think the materials of the house consist of polymer.
Polymers are defined as long-chain compounds (believe it or not, this is the first time I looked at a formal definition that I can recall. 😀
So sure there are a lot of polymers in that design (just like in more other industrial products in this day and age). A lot of them are made of recycled materials, like most of the stuff that makes up this design.
