I understand that there are prejudices, but I believe most of them come from a lack of knowledge about what green nanotechnology is.
Green nanotechnology enables the production of new biomaterials and nanostructures through biological processes, that is, through the use of living systems or their derivatives( such as microorganisms, enzymes, plant extracts, or self-assembly mechanisms) that operate with lower energy requirements and avoid the use of toxic substances or energy-intensive industrial processes. This makes it possible, in a low-energy post-fossil world, to carry out such production in local, decentralized, and sustainable ways, aligning closely with the principles of permaculture.
A biointegrated, decentralized, and ecologically oriented form of nanotechnology could therefore be understood as an advanced extension of permacultural principles. For this reason, it is essential to critically examine and actively discuss the trajectories of its development in order to define the conditions under which it can evolve in ways that genuinely support ecological regeneration, local autonomy, and long-term sustainability.
