Cátedra Madera Onesta, Universidad de Navarra and Rayder Willian Leonardo Laura, Científico investigador, Universidad de Navarra Most of us are already quite comfortable recycling our household waste. In Spain, for instance, millions of tonnes of packaging are processed every year, but did you know […]
PET (polyethylene terephthalate), a widely used polymer in packaging due to its favourable properties, increases rapidly in global plastic production and waste. Between 2000 and 2019, global plastic production rose from 234 to 460 million tonnes and is projected to reach 1,231 million tonnes by 2060. As a result, plastic waste more than doubled from […]
Spain, like many other countries with a large share of agriculture in the economy, faces significant challenges in managing the vast quantities of livestock manure produced every year. In 2020, Spain had more than 6.7 million cattle, each producing approximately 17 cubic meters of manure annually . Manure, particularly from large-scale livestock operations, creates environmental […]
A team of researchers has invented a more efficient way to extract lithium from waste liquids leached from mining sites, oil fields and used batteries. They demonstrated that a common mineral can adsorb at least five times more lithium than can be collected using previously developed adsorbent materials. The new low-cost high-lithium-uptake process presents the […]
Digital technologies have gained an essential role in societies’ development, by generating a global transformation in economic, social, and environmental dimensions. Digitalization does not just bring comfort and effectiveness in daily life but also contributes to equity and opportunities generation. However, this digital transformation is raising a fierce debate on how to ensure a positive […]

Authors: Mireia Martín, Life Cycle Thinking Group, Department of Graphic Design and Engineering Projects. University of the Basque Country (UPV/EHU) and Erlantz Lizundia, Life Cycle Thinking Group and BCMaterials One of the consequences of global population growth is an increase in food waste. This is a relevant issue not only in terms of the waste […]
Food waste represents a serious problem associated with today’s society to which a solution should be found. A notable share of the impacts originates from the fishing sector. It hardly results acceptable that, in a world with shrinking food resources, 25% of the total fishing catches end up being discarded as waste. It should be […]
In recent years, supporters of the theory of degrowth have found an ally in an imaginary “new economic theory” that has become very popular: the so-called Doughnut Economics , for the title of a book by the British economist Kate Raworth, who proposed the model in a 2012 article. Raworth is not really a degrowther […]
The cryptocurrency bitcoin now uses up more electricity a year than the whole of Argentina, according to recent estimates from the University of Cambridge. That’s because the creation of a bitcoin, in a process called mining, is achieved by powerful computers that work night and day to decode and solve complex mathematical problems. The energy […]
Until 1932, atoms were considered to consist in positive charges, called protons, located within the atomic nucleus, where the majority of the mass of the atom is concentrated, and negative charges, identified as electrons, surrounding the nucleus to make it electrically neutral. However, in 1932 James Chadwick discovered the neutron, an uncharged particle located at […]
