GECOST 2021 Conference Keynote Speaker : Conversion of Biomass waste to value added feedstock for solid biofuels and green energy production
2021 - 2021

Description Conversion of Biomass waste to value added feedstock for solid biofuels and green energy production

Keynote Speaker: Dr V.Skoulou

The exploitation of alternative, green fuels such as the lignocellulosic (woody and herbaceous) biomass waste in energy production, offers the advantages of: i) improved waste management, ii) resource efficiency, iii) reduced dependence on imported energy and iv) increased renewables usage in power production. Low carbon thermochemical processes such as pyrolysis and gasification, in combination with exploitation of biomass waste can reduce the carbon footprint of the energy production sector and offer an additional source of income to farmers and agro industries. When woody and herbaceous waste (e.g. empty fruit bunches and kernels, rice straws) are fed in raw form into fluidised bed technologies (FBGs) such gasifiers for bioenergy production, operational problems like ash fusion and bed agglomeration appear. To ensure a sustainable and efficient operation of such technologies fed on biomass waste, raw material needs to be pre-treated in order to ensure long term operation of bioenergy systems without disturbance as well as optimize the economics of these new fuels by solving logistic issues. As a result these optimised biomass fuels will accelerate the decarbonization of the energy production sector. In this way any underestimated biomass ‘waste’ sources produced locally will be upgraded to a highly desirable and sustainable feedstock for further bioenergy related uses and innovation which is brought by a multidisciplinary approach in the field.

Chem Eng Day 2021 : Avoidance of the operational problem of Bed Agglomeration during Gasification of Barley Straw in Fluidized bed energy generation technologies.
2021 - 2021

Abstract
Problematic lignocellulosic waste such as straw (around 5%wt of ash and low bulk density causing problems during reactors’ feeding) cause defluidisation in fluidized bed energy generation systems. Such waste contain much higher amount of alkali and alkali earth metals (especially K). Potassium (K) for example interacts with the cheap and easy to find bed material (silica sand), leading to bed agglomeration operational problems which in turn results in pressure drop increase and loss of fluidisation due to eutectic mixtures creation. Leaching (water washing) the problematic inorganic constitutes from such type of waste reduces the tendency towards bed agglomeration of FB technologies commonly used in wasteto-energy plants. Untreated barley straw was fed to the fluidized bed reactor at temperatures ranging from 750 to 950oC and bed agglomerated. The de-fluidization operational problem became more prominent as the bed temperature increased. On the other hand, pre-treated barley straw didn’t lead to any bed agglomeration during continuous operation and lowered gaseous emissions compared to raw barley straw. Leaching reduced also both K and chlorine (Cl) by almost 90% after leaching in the water as well as improved feeding of feedstock into the gasification system. SEM/EDX characterization of the bed material before and after de-fluidization indicated the nature of bed agglomeration phenomena and actual composition of the ash decoration on the surface of the bed material. The raw straw coating composition presented a high K content (50%wt) with low content of Si (15%wt). However, the SEM/EDX results of the bed material after gasifiying the leached straw didn’t show any agglomeration by eutectic mixtures of very low concentration of K (< 2%wt) and Si (~70%wt). The latter enabled avoidance of the FB agglomeration operational problem and decreased the chances of forming eutectic mixtures.

CEES 2021 International Conference, Spain : Thematic Session 10: Renewable Energy (RES) Technologies in Buildings and Built Environment
2021 - 2021

Description CEES 2021 : Construction Energy and Environment Sustainability International Conference , Coimbra Portugal , 12-15 October 2021

The first International Conference on Construction, Energy, Environment and Sustainability - CEES 2021 - is taking place in Coimbra, Portugal, October 2021, and is being organized by Itecons.

Globally, we are faced with resource scarcity, climate change and increased urbanisation. More than ever, there is a need for increasing the sustainability of the built environment and construction activities.

As concerns with sustainability, efficiency and wellbeing continue to grow, the construction industry must not only continue to embrace new technologies, processes and materials, but also continue to address the many challenges facing the existing building stock. The first International CEES conference aims to bring together construction, energy and environment researchers, engineers, planners, stakeholders and policy makers to address these challenges.

In order to achieve a sustainable built environment and a sustainable construction activity, professionals from a wide range of backgrounds need to work together, from researchers working on the development of innovative construction materials and technologies, on building physics and energy performance, or on studying the environmental effects of manmade infrastructure, to those working towards the adoption of the industry 4.0 principals or those working in a more regional and urban scale, all the while without neglecting the social aspect of sustainable construction and housing.
In this context, we are looking for contributions related with, but not limited to, a wide range of multidisciplinary topics, which are arranged in six general themes:

Construction materials and technologies
Building physics
Energy
Environment
Construction and industry 4.0
Community challenges and policies

and the special thematic session:

Sustainability and Resilience to Climate Change Hazards and Gender Equality _ Sustainability (MDPI)
2020 - 2021

Description Dear Colleagues,

Gender equality and inclusion are of growing importance and focus in many sectors, including education, research, business, and governance. The 2030 Agenda for Sustainable Development is envisaging building peaceful, resilient, equitable, and inclusive societies. Sustainable development implies constant evolutionary and adaptive change, while gender equality is a prerequisite to this. Gender equality is a critical goal because its implementation can foster positive cascading effects on the achievement of all SDGs, and it is directly connected to the nexus of education-sustainability. In terms of climate change-based disasters, the transition towards socio-ecological resilience should be aligned with the fundamental aspect of gender equality. Women are the victims of climate change disasters and gender equality is another parameter that must be considered in climate-based resilience. Vulnerabilities and gender inequality can impede the effectiveness and sustainability of climate change responses. Increasing gender equality has a positive impact on productivity, boosts problem-solving, and increases innovation, all of which are essential outcomes for tackling the great challenges we are facing, from health to food security, from climate change to sustainable communities. Women’s greater participation would not only be a social policy but would also enhance sustainability, resilience, and democracy. Policy planning should integrate natural and social capitals, ethics, and values, as agencies towards the acceleration of the fundamental changes for a sustainable and resilient life.

This Special Issue comprises papers that explore the multifaceted dimensions of gender equality in relation to sustainability and resilience to climate change hazards. Through a series of papers, it explores promising approaches for transforming higher education, research, leadership, policy making, and institutions towards gender equality. Gender equality is a wicked problem interconnected with overlapping complexities inherent in our society that create symbiotic relationships that connect issues to one another. Therefore, gender equality is interconnected with the global challenges of climate change, health, security of food, water, waste, energy, and biodiversity. Vulnerabilities and gender inequality can impede the effectiveness and sustainability of climate change responses. Increasing gender equality has a positive impact on productivity, boosts problem-solving and increases innovation, and creates sustainable and inclusive communities. Women’s greater participation and empowerment would enhance sustainability, resilience, and democracy. Policy planning should integrate natural and social capitals, ethics, and values, as agencies towards the acceleration of the fundamental changes for a sustainable and resilient life. The purpose of the Special Issue is to contribute responding to climate change (mitigation, adaptation, technology transfer and financing) by including a gender lens and arguing that gender be horizontally integrated into climate change response efforts.

Pretreatment of lignocellulosic biomass waste for enhanced thermochemical decomposition for bioenergy production- Chemical Engineering Day 2019
2019 - 2019

Description Pretreatment of lignocellulosic biomass waste for enhanced thermochemical decomposition for bioenergy production.

by H.A. Alabdrabalameer, M.J. Taylor and V.Skoulou*


The pre-treatment of woody and herbaceous lignocellulosic biomass waste has been explored to enhance its properties as a solid fuel source and control the inherent parameters such as moisture and ash content (inorganic residues that remain after combustion), as well as oxygen content, low calorific value, high volatilIly and low bulk density. Various chemical and physicochemical methods of leaching such as; hotplate, microwave and mechano-acoustic technologies have been used to combat the issues mentioned above, as well as determining an optimum substrate particle size via milling techniques. Facilitating pre-treatments under mild conditions have been found to not only be beneficial in the reduction of inorganic components such as P, S, Na, K and Ca (as determined by ICP-OES). They have been found to cause no detrimental effect to the complex organic matrix, where lignin and hemicellulose content of the substrate when measured by FTIR. Pre-treatment studies have been found to reduce the overall cellulosic crystallinity (calculated by Segal’s equation in PXRD) which is beneficial for thermochemical upgrading when using pyrolysis and gasification. Thermochemical studies have been conducted via thermogravimetric analysis (TGA) under N2 at varying temperatures to model pyrolysis conditions to calculate the biomass reactivity and heating value. It has been found that microwave based leaching is the most effective at reducing inorganic species and therefore lowering the ash content while maintaining the lignin, hemicellulose and cellulose content, as determined by ultimate analysis.

Bioenergy and Biochar: Repurposing Waste to Sustainable Energy and Materials Special Issue of Energies Journal (MDPI)
2019 - 2020

Description All types of biomass, and their waste, comprised one the pillars of the pre-industrial, pre-fossil fuel, agriculture-based economies of the past. Traditional practices of biomass waste management were applied, but not necessarily in a sophisticated and efficient way, and covered all the way up from agricultural activities to food production, animal feed, natural fibre separation as well as processing of forest-wood. The modern bioeconomy sector, though, includes new circular economy energy and materials streams of added value products, such as gaseous, liquid and solid biofuels and bioenergy generation routes, and biochar production, along with all the previously mentioned traditional bioeconomy emerged products.

The aim of this Special Issue is to include the latest bioenergy and biochar advancements and incorporation to a bioeconomy in transition. This Special Issue focuses on nature, properties, upgrading and bioenergy generation processes from all types of biomass waste and biochars originating from biomass waste. Overviews of international ongoing and collaborative, transdisciplinary research projects, technology transfer and policy development in the field are also welcome. A transdisciplinary approach in order to examine, explore and critically engage with issues, advances and barriers of the attempt are also encouraged.
