Assessing the exergy degradation of the natural capital: From Szargut's updated reference environment to the new thermoecological-cost methodology

Energy, 163:1140 - 1149.

This paper shows the common developments performed by the Institute of Thermal Technology and the Research Centre for Energy Resources and Consumption regarding the assessment of natural resource degradation. Particularly, it shows the last model of the Szargut's Reference Environment, which was updated with new geological and geochemical information not available when it was originally developed. This R.E. allows for a more precise assessment of the chemical exergy of natural resources. The paper further shows the concept of the Exergy Replacement Costs (ERC) and the model of Thanatia, a theory that serves to assess the concentration exergy of mineral resources based on their scarcity degree in Nature. The combination of the ERC concept with the Thermo-Ecological Cost method (TEC), originally proposed by Szargut to assess products considering the exergy associated to the consumption of non-renewable resources extracted directly from Nature, gave birth to the TERC methodology, to better assess the degradation of the mineral capital.

The Material Limits of Energy Transition: Thanatia

Antonio Valero Capilla, Alicia Valero Delgado and Guiomar Calvo

This book provides a holistic view of raw mineral depletion in the context of renewable energy transistion.

The material limits Thanatia


Thanatia. Los límites minerales del planeta

We need a material transition, not only energetic, that restores nature and effectively reuses materials. Gaia must be cared for by extending life on Earth and slowing its degradation towards Thanatia.

Thermodynamics for Sustainable Management of Natural Resources

Cover Thermodynamics

Wojciech Stanek (Editor)

This book examines ways of assessing the rational management of nonrenewable resources. Integrating numerous methods, it systematically exposes the strengths of exergy analysis in resources management.

Thanatia: The Destiny of the Earth's Mineral Resources

Cover Thanatia

A Thermodynamic Cradle-to-Cradle Assessment by (author): Antonio Valero Capilla and Alicia Valero Delgado

Is Gaia becoming Thanatia, a resource exhausted planet? For how long can our high-tech society be sustained in the light of declining mineral ore grades, heavy dependence on un-recycled critical metals and accelerated material dispersion? These are all root causes of future disruptions that need to be addressed today.
