In this paper we inquire into the fundamental assumptions that underpin the ideal of the Bio-Based Economy (BBE) as it is currently developed. By interpreting the BBE from the philosophical perspective on economy developed by Georges Bataille, we demonstrate how the BBE is fully premised on a thinking of scarcity. As a result, the BBE exclusively frames economic problems in terms of efficient production, endeavoring to exclude a thinking of abundance and wastefulness. Our hypothesis is that this not only entails a number of internal tensions and inconsistencies with regard to the ideal of BBE, but ultimately undermines the ideal itself, by pushing purported regenerativity into a cataclysmic and terminal discharge. We here point to the strategies that the BBE employs in this exclusion, the fundamental assumptions regarding the relation between energy and economy that underpin this endeavor, as well as to the resulting inconsistencies and their catastrophic consequences. We finally argue for the introduction of the presently excluded question of abundance and wastefulness and explore the implications of such a question for the ideal of a zero-waste humanity.

This paper provides a phenomenological analysis of postphenomenological philosophy of technology. While acknowledging that the results of its analyses are to be recognized as original, insightful, and valuable, we will argue that in its execution of the empirical turn, postphenomenology forfeits a phenomenological dimension of questioning. By contrasting the postphenomenological method with Heidegger's understanding of phenomenology as developed in his early Freiburg lectures and in Being and Time, we will show how the postphenomenological method must be understood as mediation theory, which adheres to what Heidegger calls the theoretical attitude. This leaves undiscussed how mediation theory about ontic beings (i.e.,technologies) involves a specific ontological mode of relating to beings, whereas consideration of this mode is precisely the concern of phenomenology. This ontological dimension is important to consider, since we will argue that postphenomenology is unwittingly technically mediated in an ontological way. The upshot of this is that in its dismissal of Heidegger's questioning of technology as belonging to Bclassical philosophy of technology,^postphenomenology implicitly adheres to what Heidegger calls technology as Enframing. We argue that postphenomenology overlooks its own adherence to the theoretical attitude and ultimately to Enframing, and we will conclude with calling for a phenomenological questioning of the dimension that postphenomenology presently leaves unthought, meaning that we will develop a plea for a rehabilitation of the ontological dimension in the philosophy of technology.

In this paper, we argue that the Anthropocene is relevant for philosophy of technology because it makes us sensitive to the ontological dimension of contemporary technology. In §1, we show how the Anthropocene has ontological status insofar as the Anthropocenic world appears as managerial resource to us as managers of our planetary oikos. Next, we confront this interpretation of the Anthropocene with Heidegger’s notion of “Enframing” to suggest that the former offers a concrete experience of Heidegger’s abstract, notoriously difficult, and allegedly totalitarian concept (§2). In consequence, technology in the Anthropocene cannot be limited to the ontic domain of artefacts, but must be acknowledged to concern the whole of Being. This also indicates how the Anthropocene has a technical origin in an ontological sense, which is taken to imply that the issue of human responsibility must be primarily understood in terms of responsivity. In the final section (§3), we show how the Anthropocene is ambiguous insofar as it both accords and discords with what Heidegger calls the “danger” of technology. In light of this ambiguity, the Earth gains ontic-ontological status, and we therefore argue that Heidegger’s unidirectional consideration concerning the relation between being and beings must be reoriented. We conclude that the Anthropocene entails that Heidegger’s consideration of the “saving power” of technology as well as the comportment of “releasement” must become Earthbound, thereby introducing us to a saving Earth.

In the unfolding debate on the prospects, challenges and viability of the imminent transition towards a 'Bio-Based Society' (BBS) or 'Bio-based Economy'-i.e. the replacement of fossil fuels by biomass as a basic resource for the production of energy, materials and food, 'big' concepts tend to play an important role, such as, for instance, 'sustainability', 'global justice' and (last but not least) 'naturalness'. The latter concept is, perhaps, the most challenging and intriguing one. In public debates concerning biotechnological interactions with the natural environment, the use of terms such as 'nature' and 'naturalness' is both inevitable and hazardous (given the fact that they are so notoriously difficult to define). Indeed, various conflicting interpretations of naturalness play a role on both sides (pro-and con) of the current debate. This paper aims to analyse and critically assess the role of 'nature-speak' in the BBS transition. We will begin with a concise overview of the vicissitudes of the nature-concept so far, focussing on how modern science and technology have challenged and affected our understanding of what nature is. Subsequently, we describe how 'naturalness' functions in the unfolding BBS debate. Finally, we will focus on a particular case study, namely the production of rubber with the help of natural latex coming from dandelion plants rather than from (tropical) rubber trees. On the one hand, this is presented as a more natural and naturefriendly way of producing rubber. On the other hand, it is a sophisticated process, involving high technology and primarily focussed on competitiveness on the global market. To what extent or in what sense can dandelion latex be regarded as more
