Quantification of the impact of the end-of-life scenario on the overall resource consumption for a dwelling house

Resources, Conservation and Recycling, 53:231-236.

In this work, fractions that are the result of the demolition phase of a dwelling house have been investigated with respect to their recovery potential: stony material, wood, metals, glass, synthetic materials and a rest fraction. Depending on their nature, different alternative end-of-life scenarios have been investigated to replace disposal, such as re-use, recycling or incineration with heat and electricity production. All resources necessary for these scenarios have been inventoried. At the same time, those that are not longer necessary for the disposal and those that would have been necessary to make the obtained products from virgin resources are quantified. Based on these three items, the overall balance results into the calculation of net virgin resource savings for different end-of-life scenarios, quantified in Cumulative Exergy Consumption (MJ of exergy). For this specific case, the best end-of-life scenario can save virgin natural resources with a content of 258 GJ of exergy. Looking at the entire life cycle of the house, i.e. construction phase, use phase and end-of-life phase, the quantitative analysis shows a saving of virgin natural resources of 15% with the implementation of the best end-of-life scenario instead of disposal as end-of-life.

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

 Antonio Valero Capilla and Alicia Valero Delgado interviewed by Adrián Almazán

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.
