Using lightweight airframe materials in aircraft structures and investigating potential reinforcement effects with sustainable aviation fuels: An analysis of environmental and economic impacts

open access: yesJournal of Industrial Ecology, Volume 29, Issue 4, Page 1135-1150, August 2025.
Abstract Using lightweight materials in aircraft structures, especially carbon fiber reinforced polymer (CFRP), can be an option for achieving aviation's ambitious emission reduction goals. However, using CFRP can be associated with adverse environmental and economic impacts, which can relativize its potential benefits.

Combining dynamic life cycle assessment and net ecosystem exchange through the framework of biobased materials and products‐life cycle assessment (BBM‐LCA): application to polylactic acid

open access: yesBiofuels, Bioproducts and Biorefining, Volume 19, Issue 4, Page 1075-1087, July/August 2025.
Abstract Biobased products can achieve carbon negativity by storing biogenic carbon in the technosphere through circular loops. Quantifying these benefits requires quantitative assessment tools such as life cycle assessment (LCA). However, the LCA of biobased materials is not straightforward due to the complexity of addressing agroecosystem carbon ...

Earth as a Hybrid Planet - The Anthropocene in an Evolutionary Astrobiological Context

open access: yes, 2017
We develop a classification scheme for the evolutionary state of planets based on the non-equilibrium thermodynamics of their coupled systems, including the presence of a biosphere and the possibility of what we call an agency-dominated biosphere (i.e ...

The Anthropocene and Its Contenders: Cross‐Disciplinary Tools for a Nationally Divided Humanity

open access: yesEarth's Future, Volume 13, Issue 7, July 2025.
Abstract Building on two essays previously published in Earth's Future, this Commentary aims to further and expand the debate by considering two indirectly correlated aspects: interdisciplinarity and internationalism, both of which can find a powerful ally in the notion of the Anthropocene.

Improving of the wear resistance of working parts agricultural machinery by the implementation of the effect of self-sharpening [PDF]

open access: yes, 2016
The failure of the cutting elements of farm machinery is due to the blunting of cutting edges (increase of their radius) till the limit values. The most effective method for increasing the wear resistance of farm machinery is the realization of self ...

Modelling the valuesphere and the ecosphere: Integrating the decision makers' perspectives into LCA [PDF]

open access: yes, 2018
Methods for Life Cycle Impact Assessment have to cope with two critical aspects, the uncertainty in values and the (unknown) system behaviour. LCA methodology should cope explicitly with these subjective elements.
