Nanotechnology has recently been identified with principles of sustainability and with a ‘green’ agenda generally . Some maintain that this green dream of nanotechnology is a rather ephemeral societal phenomenon that owes its existence to the campaign ploys of politics and business. This paper argues that deeper lying societal and cognitive structures are at work here that complement or even substantiate in some sense the seemingly manipulative saying of a greening of nanotechnologies. Taking seriously the concept of ‘green nano’, this (...) paper examines the common ground between sustainability discourse and the discourse of nanotechnology. Green nanotechnology is understood as a boundary concept in which disparate discourses and concepts join together. The primary concern of the paper is to show that nanodiscourse and ecodiscourse share visions of control and of excess. Both ecotechnology and nanotechnology accept and incorporate arguments about limited growth, and each develops strategies of control—be it through a new-found precision in the control of material flows or through greater efficiency in product design.

My hypothesis in this article is that it is possible to use the philosophical concept of technics to solve a conflict in contemporary continental ontology between speculative materialist and phenomenological approaches. More precisely, I will show that technics gives a privileged access to ontology because it leads to a “materialist” ontology, avoiding both theological and nihilistic approaches, and because technics, being by definition a domain of artificiality, precludes any explication of it in terms of naturalist materialism. I start by critically (...) examining two techno-ontologies that come from speculative realism and object-oriented ontology: Levi R. Bryant’s onto-cartography and Graham Harman’s tool-being. I then present, as a counter-position, Jean-Luc Nancy’s idea of “ecotechnology”. In conclusion, I evaluate the usefulness of the concept of technics for ontology and argue that Nancy’s post-phenomenological approach is preferable because it avoids indefensible hypostases and is more attentive to its own discursive status.

In this paper I critically reflect on the sustainability potential of biomimetic technologies by focusing on writings of the German philosopher Peter Sloterdijk. Although I agree with Sloterdijk that biomimetic technologies – or, as he calls them, ‘homeotechnologies’ – offer specific opportunities for a more peaceful co-existence of humans and nature, I will argue that his reflections are based on a series of problematic assumptions. I will conclude by arguing that the ‘homeotechnological turn’ can be effected only if it is (...) developed within the context of a different ecological ethos from the technocentric ethos that currently dominates our attitude towards nature.
