Dry and wet routes in the ceramic tile manufacturing process refer to two different technologies on how to prepare the raw materials for the forming stage. As a result of both routes a granulated solid ready to be used in the pressing stage is obtained, but the characteristics of these granulates are strongly influenced by preparation route. Historically, the dry route was firstly developed, however when the quality standards and the size of the tiles increased, the wet route was successfully introduced into the manufacturing process, and from 1990 decade it is the most widespread technology to prepare the body raw materials in the world. The powder obtained with the wet route, which has finer particle sizes and higher flowability, allowed the companies to readily produce higher quality ceramic tiles and higher sizes, but its processing is more demanding in terms of energy and water consumption and, consequently, entailing higher economic and environmental costs.
Nevertheless, the new development in dry milling and granulation systems, the growing awareness on environmental impacts and European Union energy policy, and the successful use of the dry route in some important producer countries (especially Brazil), are hurrying up a reconsideration of the production process in the world.
In this new scenario, the implementation of the dry route has been seen as an interesting alternative to produce ceramic tiles with lower environmental burdens and, as a consequence of that, a significant number of works have been reported in the last years on this technology, both by applied research centres and machinery producers.
In this communication, a technical and environmental comparison between the dry and wet route is presented based on the most recent advancements, in order to provide information about this controversial issue in the ceramic tile world: the use of the dry route to produce high quality ceramic tiles.

The ceramic tile industry consumes considerable amounts of energy along its value chain, from mining activities, transport of materials to the processing plants, processing of those materials for tile production, the tile production process and storage and the delivery of the tiles once packaged. The last century saw three radical transitions from traditional biomass to hydrocarbon resources, first to fuel mid-century and then to natural gas in the 1980s. Although fuel and electricity are consumed in the sector, the main energy used currently is natural gas.
However, there is an awareness of the environmental challenges facing the ceramic tile industry in the coming years, especially those related to energy and emissions (Monfort et al., 2014), and the potential of its innovation system, through environmental innovation, to generate and adapt technologies and improve production techniques (Gabaldón-Estevan et al., 2014). Therefore, in the present paper we present a socio-technical study on the viability of the incorporation of biofuels in the energy mix of the Spanish ceramic industry.
The objectives of this paper are to (1) identify and evaluate potential new uses of biomass in manufacturing process of ceramic products; (2) calculate the reduced environmental impact from the manufacture ceramic materials through a reduction in carbon dioxide emissions; (3) estimate the effects on rural development and job creation can bring the best use of resources and reduction of forest, agricultural and/or other debris, and (4) characterize the institutional framework and current socio-economic environment for the implementation of biomass as an energy source, on an industrial scale in the ceramic industry.

Valorization of forest and agricultural biomass for the spanish ceramic tile ...Daniel Gabadón-Estevan
Since ceramic tile industry is an energy intensive industry, European ceramic companies are challenged to reduce their CO2 emissions in the medium and long-term. According the Roadmap for moving to a low-carbon economy in 2050 (European Commission, 2011) the objective is to achieve a reduction in CO2 emissions of between 34% and 40% by 2030, and between 83% and 87% by 2050.
In the present paper we present a study on the viability of the incorporation of biofuels in the energy mix of the Spanish ceramic industry with the objective of (1) identifying the potential use of biomass resources, with a special focus of forest and agricultural biomass, in the manufacturing process of ceramic tile products; (2) identify in what part of the production process it can be introduced; and (3) calculate the reduced environmental impact from the manufacture of ceramic materials through a reduction in carbon dioxide emissions.
In order to proceed we firstly present the relevant state of the art for the study of the use of biomass for the ceramic manufacturing process. We continue with the methodology for biomass resources evaluation and present relevant data on forest and agricultural biomass for the ceramic tile industry. We then present data on the evolution and actual energy demand of the ceramic tile industry to characterize its energy demand. And then we identify an opportunity for biomass use in a specific phase of the manufacture of ceramic products, estimating the savings of fossil fuels and the reduction of carbon dioxide emissions and therefore assessing the environmental impact reduction through the introduction of biomass in the manufacturing process of ceramic tile products.

Evaluating an experiment. The Case of Fare-Free Public Transportation System ...Daniel Gabadón-Estevan
In this research, we focus on the case of an environmental innovation regarding transport policy, the implementation of the free fare policy on public transport (PT) for all inhabitants of Tallinn, Estonia. Tallinn, with 439,000 inhabitants in 2015, is the capital of Estonia and the largest city in the country. However, over the last two decades the share of PT trips decreased dramatically. After a public opinion poll in 2012, in which over 75% of the participants voted for a fare-free transportation system (FFPTS) in Tallinn, the new policy was implemented on 1st January 2013. From that date residents registered in Tallinn could use all PT services (buses, trams, trolley-buses) operated by city-run operators for free. Later the free fare system was implemented also on trains within Tallinn. For this we have undertaken a project to evaluate the implementation of the free fare policy on PT in Tallinn as a case of an experiment regard-ing innovation in transport policy with potential environmental consequences. We evaluate this experi-ment by comparing the previous with the actual situation regarding several indicators such as PT use, change in modal split, pollution, etc. This is done by interviewing relevant informers (stakeholders) to identify the main enablers of and obstacles to the use of the FFPTS in Tallinn as well as possible limita-tions of this experiment to contribute to sustainable development. In exploring the main enablers of and obstacles to the implementation of the FFPTS in Tallinn, we apply the multi-level model of social innova-tion (Geels et al 2001) that allows for systematic exploration of the role of institutional regime (market, policy and science interactions) and the impact of the so-called ‘landscape’ level of societal values, over-all paradigms and megatrends that both shape the success of innovation in socio-technical systems. The research allows us to deepen our understanding on innovation governance in relation to mitigation and adaptation, as well as identifying effective ways of stimulating and diffusing experiments on policy and governance innovations. Our results show that the interlink between local and national politics have a determinant effect not only on the initiatives taken and the support they achieve but also on the interpretation of the success of those initiatives and their stability. Also, the discourses build around those initiatives and “unexpected” consequences of the policy are reported.

Pursuing cumulative advantage through early childhood education. the paradox ...Daniel Gabadón-Estevan
There is no doubt that school credentials are at the centre of the stratification process in meritocratic societies and there is evidence that the starting point is well ahead of the primary (compulsory) education (Lareau, A., 2003; Kalil, A., Ryan, R. & Corey, M., 2012). Through early childhood education parents not only invest in their offspring’s future chances to maintain or increase their relative position in the social ladder by investing in their human and social capital (Keys et al., 2013), but also perceive that educational decisions as providing a framework that will influence child development in terms of life goals, life values and attitudes (Galán, 2009; Ballantine & Hammack, 2011; Ryan, 2001).
However, how much parents are able to determine children school characteristic is dependent on the institutional arrangements and the welfare regime where their educational system is set (Feito, 1994; Mancebón Torrubia, 2007; Fernández Enguita, 2008). At some regions, such as for instance the Valencia region in Spain, there has been a consistent policy promoting the development of private early childhood educational facilities that have reinforced in recent years the already none-comprehensive school system (Sintes, E., 2012; Ancheta Arrabal, A., 2012; Fernández Enguita, M., 2002). In the present study we combine both an institutional and a case study analysis on the city of Valencia, to deepen the understanding on how the early childhood education choice operates.
La tertulia dialógica es una experiencia de éxito que se deriva de la metodología comunicativa crítica, y trata de modificar tanto la calidad, la cantidad, como los actores implicados en las interacciones en el aula, dando más peso a la interacción del alunado entre sí y con el profesorado, todo ello con la finalidad de propiciar una mayor implicación y motivación, mejorar el desarrollo de competencias, y conseguir una mejor y más duradera adquisición de conocimientos por parte del alumnado. El objetivo de este trabajo es evaluar los resultados de una experiencia innovadora llevada a cabo con dos grupos del Grado en Maestro/a en Educación Infantil y Grado en Maestro/a en Educación Primaria, en la Universitat de València. La experiencia innovadora consistió en la celebración de tertulias dialógicas en grupos reducidos de máximo ocho alumnas y alumnos, entorno a la lectura del libro Mal de escuela de Daniel Pennac (2012). El alumnado podía optar por leer el libro como una de las actividades evaluables para las asignaturas de Estructura Social y Educación (1er curso) y Sociología de la Educación (2do curso) y la participación en las tertulias era voluntaria. Para facilitar el análisis de las tertulias estas fueron grabadas haciendo uso de las instalaciones del Social·lab, laboratorio de ciencias sociales de la Facultat de Ciencies Socials de la UV. En este trabajo presentamos los primeros resultados del análisis de esta aplicación de las tertulias dialógicas como recurso docente innovador en estudios de grado en la UV.

Las tertulias dialógicas y los grupos interactivos son dos experiencias de éxito, derivadas de la metodología comunicativa crítica, que se están desarrollando en las comunidades de aprendizaje. El impacto que han tenido en la mejora de los resultados académicos del alumnado de primaria ha hecho que progresivamente se expanda su uso a otros niveles educativos. Estas prácticas, derivadas de la evidencia reportada en el proyecto europeo “INCLUD-ED Strategies for inclusion and social cohesion from education in Europe”, tratan de modificar el modo en el que la comunidad educativa interacciona en el aula, dando más peso a la interacción del y con el alumnado. Los beneficios derivados de su aplicación se vienen refiriendo a la mayor implicación y motivación del alumnado, el mejor desarrollo de competencias y la mejor y más duradera adquisición de conocimientos. En nuestro contexto educativo, la mayoría de iniciativas reportadas que incluyen tertulias dialógicas y grupos interactivos se centran en aulas de educación primaria, refiriéndose principalmente a Centros compensatorios de Acción Educativa Especial y Centros de Acción Educativa Singular (CAES). Sin embargo, poco ha trascendido de su aplicación a otros niveles educativos, como por ejemplo en el ámbito universitario. En consecuencia, el presente trabajo trata de cubrir este vacío mediante una revisión del estado del arte en cuanto a la aplicación de tertulias dialógicas y grupos interactivos en contextos de educación superior.
único patrón, y en el caso español se han significado dos autores como referentes visibles de dos maneras antagónicas de entender la crianza en función de su rechazo (Eduard Estivill) o aceptación (Carlos González) de la teoría del apego desarrollada por John Bowlby. En este trabajo presentamos una manera novedosa de abordar la relación entre la crianza desarrollada en el seno familiar, y las demandas educativas que plantean las familias a la hora de elegir centro de educación infantil, a través de un cuestionario ad-hoc, del proyecto “Modelos Parentales y Demandas Educativas”, 2012-2013, en el que se recogen ítems tanto referentes a las prácticas de crianza como a las demandas educativas.
Los resultados de la investigación nos confirman la variabilidad existente en cuanto a cuidado y crianza desde el ámbito familiar. Junto a familias que practican colecho y proveen lactancias en mayor o menor medida prolongadas, hayamos también familias que no han practicado estas opciones de crianza. Otras diferencias entre las prácticas de crianza se refieren al recurso a los permisos parentales, la acomodación de la descendencia en habitaciones diferentes a la de los progenitores, o la edad a la que inician su institucionalización educativa. El estudio nos permite también observar la relación entre las prácticas de crianza de las familias encuestadas y sus demandas educativas.
In recent years, efforts have been directed towards understanding how innovation is achieved, with special emphasis to the role of networks for the interaction between scientific and technological environments with the productive environment. In this paper a revision of the main theoretical contributions on the analysis of the role of social networks and interactions for innovation is presented. The theoretical examination is illustrated with the analysis of the ceramic tile industrial district of Castellon in Spain and the role of social relations as mediators between the different agents that form its innovation system. Specifically, the analysis is directed towards the understanding of how, within the structure of a given district, these relations articulate the interaction of those agents that actively participate in the development, diffusion or adoption of innovations, for the purpose of better illustrating the example, some references to its counterpart district at Sassuolo in Italy are brought about.

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.

3. Europe 2020’s focus on Climate Change and Energy
Sustainability establishes three specific targets for 2020:
A.A reduction of greenhouse emissions (reference year
1990) by at least 20%
B.Obtaining 20% of the energy from renewable sources
C.Increase by 20% the energy efficiency
Motivation: 202002
5. Motivation: 205004
Electrification of kilns = not currently
economically viable
Carbon Capture and Storage = unlikely to
be economically viable until well-
established
Among the so-called widespread
technologies to implement at ceramic
industrial facilities:
o changes on the raw materials
formulation for more efficient firing,
o energy management
o process optimization.

15. Conclusions I14
From the point of view of sustainability, it seems clear that the dry route to
prepare raw materials is more appropriate, but the most used is the wet
method because of the properties of the final granulate obtained.
However nowadays the technology for the dry preparation of raw materials
(pendulum mills and granulators) has improved substantially, and the
properties of the granulates obtained are similar to the ones obtained from the
spray dryer, allowing the manufacture of nearly all types of tiles.
A further advantage of the wet method being that the waste water of the
manufacturing process can be recycled in the preparation of the slurry,
reducing the fresh water consumption, and the environmental impact of the
overall process.
It should also be pointed out that the wet method allows the implementation of
cogeneration systems, facilitating the companies the generation of their own
electricity and reducing their dependence on the electricity grid, although this
is very dependent on legislation on cogeneration.
16. Conclusions II15
This study reflects the complexity of the process of transferring the latest
developments to productive sector and how those factors will affect the rate of
adoption of new or improved technologies.
As we have already shown, not always the most energetically efficient process
is the one more spread even within the EU due to the existence and interlink
of other factors such technology development, product quality, or already
existing infrastructures (atomizers).
“Innovation is often the case, in fact, of looking to
apply old solutions to new problems and applying
new solutions to old problems”
[A Reed – 2001; 126]
Last but not least, environmental and
energy policy are an essential element
when establishing paths towards cleaner
production.
