Author(s): Srinath Ramagiri, Shehan Lowe, Ahmed Teyeb, Arman Zonuzi, Evelyne El Masri,Tat-Hean Gan, Jamil Kanfoud and Martyn Marshall

Abstract

Due to the inherent uncertainty and potential disruptions in the supply chain, the global community is adopting a more cautious approach to meeting its energy needs. Climate change, material availability, and recycling for sustainability are also pressing issues. The material processing industries, which encompass activities such as mining ore, extracting materials, melting them, and manufacturing components, require a large amount of energy. These industries often include a heat treatment process as part of the manufacturing process, which can be a major energy consumer. For example, heat treatment can account for 20% of energy usage in a non-ferrous foundry. Pre-heating and heat treatment also requires a significant amount of energy in the ferrous-based industry. In this work, our goal is to increase the efficiency of energy usage in these industries through the use of machine learning models to optimize processes. We will analyze the processes in these industries and create machine learning models to identify the optimal operating parameters for the best output with minimal energy consumption.

Highlights
  • 1. Numerical simulations are carried out based on a case study from glass manufacturing industry. Heat treatment process is identified for the study.
  • 2. Heat treatment process parameters such as Exit temperature ( 0 C), cooling rate above S.T (0C/min), and Annealing Temperature ( 0 C) are identified as input parameters. Energy consumed (kJ) and maximum stress (MPa) (output parameters) are evaluated for a particular set of input parameters.
  • 3. Input and output parameters set after the simulations are used to create regression models using Neural Networks.
  • 4. An optimisation framework is created using the regression model which enable us to evaluate heat treatment process parameter values for a particular value of energy consumption and maximum stress.
  • 5. The framework is used to evaluate various possible set of input parameters in-order to reduce the energy consumption for the same quality of the product (constant maximum stress).

Article Title: Trace elements supplementation as management tool for anaerobic digestion process

Author(s): Tina Kegl

Abstract

Waste management and energy crisis are some of the greatest issues that the world is facing today. This problem can be mitigated by anaerobic digestion (AD), where microorganisms in the absence of oxygen produce biogas from organic waste. A useful tool for AD process understanding and optimization is numerical simulation by using mechanistically inspired mathematical models. In this paper, attention is focused on the impact of trace elements in the AD process of a full-scale biogas plant. Special emphasis is put on the optimization of concentrations of trace elements, which are added into the bioreactor in order to improve the produced biogas quantity and quality. Numerical simulation of the AD process is performed by a complex self-developed BioModel, where 187 model parameters are calibrated using an active set optimization procedure. The agreement of the obtained results of numerical simulation in a single CSTR and the measured AD performance over a period of one year, confirms the reliability of the used BioModel and the efficiently of the active set optimization procedure build around a gradient-based algorithm. In order to optimize the amount of added trace elements, three different cases involving various objective and constraints functions are defined. The obtained results show that the optimized amounts of added trace elements enhance the produced biogas essentially by keeping the quality of the biogas within the desired limits. The optimization procedure is numerically efficient, especially if the computation of design derivatives is parallelized.

Keywords

BioModel calibration, active set optimization procedure, approximation gradient-based algorithm

Highlights
  • Prediction of AD performance by BioModel including the impacts of trace elements during AD process
  • Usage of gradient-based optimization algorithm for BioModel calibration and AD process optimization
  • The optimized amounts of added trace elements improve the AD process significantly

Article Title: Soiling Effects on Solar Photovoltaics Power Plants in Three Climate Zones in Saudi Arabia

Author(s): Mohammed O. Al Harbi, Abdulrahman M. Al Amoud and Zeyad A. Al Mutairi

Abstract

The Kingdom of Saudi Arabia (KSA) has a strong potential for renewable energy due to its location within the “global sun belt” range. Recently, KSA has paid more attention to this field, ultimately launching the National Renewable Energy Program (NREP) with a total capacity of up to 58.7 GW; composed mainly of solar and wind energy. Solar energy (PV), in particular, is expected to reach 40 GW by 2030. Due to the Kingdom’s desert climate, one of the concerns that might affect NREP is soiling from dust, leaves, pollen, and bird droppings that ensues negative effects on solar power production. The paper will investigate the effects of soiling on solar power production through simulating real power plants using PVsyst Software in three different climate zones in Saudi Arabia. Finally, the effect of soiling on the Levelized Cost of Energy LCOE and the financial analysis are also discussed.

Article Title: India Phasing Out Fluorescents Lights an Opportunity to Adopt 100% LED Lighting

Author(s): Kishore Kumar PVN and PK Mukherjee

Abstract

Millions across India use electric lights. The lighting market has increased exponentially over the years due to rapid population growth, more dwelling units, the concept of intelligent lighting, and electrification at remote places. In Fiscal Year 2020-21, India manufactured about 1.3 billion lamps and tube lights. The lighting segment consumes approximately 18% of total electricity use in the residential sector.

Energy-efficient lighting is one of the most cost-effective measures to address the impacts of growing electricity demand from the sector. In Fiscal Year 2014-15, most Indians uses incandescent bulbs, which dominated the market at close to 60% followed by fluorescent lamps and tube lights at 40%, whereas the LED market was less than 1%. The adoption of efficient LED lighting was slow due to the high price of the bulb. Recognizing this, India enabled the growth in LED market demand with various efficiency programs, mass procurement exercises, and providing incentives, these resulted in an increase of its market by close to 56% in Fiscal Year 2020-21 and declined the share of incandescent bulbs to 36%, thus fluorescent lighting to 7%. Moreover, last year India committed to the phaseout of compact fluorescent lamps by 2025 and fluorescent tube lights by 2027 at Minamata Convention to protect human health and the environment from the adverse effects of mercury. These envisage an opportunity to India for replacing fluorescent lights with LED lighting and lay out action plans to shift from inefficient incandescent bulbs to LED bulbs.

This paper analyses and discusses the India lighting programs, efficiency policies, trends in market growth, technology evolution, the market transformation toward efficient lighting, and the opportunities to develop new efficiency policies that drive the market, resulting in to promote of 100% LED lighting, further assess its impacts of energy saving and GHG emissions reduction potential.

Article Title: Can free-floating shared e-scooter reduce greenhouse gas emissions from urban transportation? Evidence from Life Cycle Assessment Perspective

Author(s): Shengjie Dong, Shouheng Sun and Weicai Wang

Abstract

Free-floating shared e-scooter (FFSE) programs have been widely promoted around the world in the past few years, but its impact on the environment remains unclear. This study quantitatively estimates the impact of FFSE promotion on greenhouse gas (GHG) emissions using a life cycle assessment (LCA) perspective. Specifically, based on the actual operation characteristics of the FFSE fleet and the user travel behavior data, it empirically investigates the GHG emissions reduction effect of FFES programs on the urban transportation in 20 cities around the Europe and North America. The results show that FFSE was not an environmentally friendly transport mode and has not achieved desirable environmental benefits. The average life cycle GHG emission intensity of FFSE was about 150 –600 g CO 2 -eq/pkm, resulting in an average increase of about 41–480 g CO 2 -eq per kilometer of FFSE trip. The vehicle manufacturing was the primary source of GHG emissions during the life cycle of shared e-scooter, followed by the rebalancing, collection and recharging activities. Sensitivity analysis shows that short service life and low daily turnover rate of the shared e-scooter are the key factors affecting the environmental sustainability of FFSE. In addition, it is worth noting that the regional differences in the operating characteristics and development status of the FFSE market and the corresponding environmental impacts vary greatly. Therefore, authorities should formulate appropriate FFSE plans based on the current geography and market situation and the urban transportation development objectives. This empirical study helps to better understand the environmental impact of the FFSE program and offers valuable references for improving urban sustainability.

Article Title: Characteristics Influence of Wave Run-up Under Coastal Velocity in River Embankments

Author(s): Junbao Huang, Haijing Li and Jie Shao

Abstract

The influence of coastal velocity is rarely considered in the determination of wave run-up parameters in river embankment design. Physical model tests of river embankment wave run-up under the combined action of incident wave and coastal current were conducted in a wave harbor pool, and the influence of coastal velocity on wave run-up characteristics was studied. The results show that the coastal velocity has a significant effect on the wave run-up of the river embankment. Under the same incident wave height level, the larger the coastal velocity is, the smaller the wave run-up will be, and as the incident wave height increases, the absolute value of the coastal velocity to the wave run-up will decrease more obviously. Under the same level of coastal velocity, the higher the incident wave height is, the higher the wave run-up will be, and as the coastal velocity increases, the reduction of wave run-up will also be greater. Two parameters, the wave run-up reduction coefficient and the wave current factor, have a good quadratic relationship. With the increase of wave current factor, the wave run-up reduction coefficient KU shows a decreasing trend. The empirical formula obtained by fitting can provide important scientific reference for river embankment design.

Article Title: Development of sustainable concrete using Imperial smelting furnace slag and assessment of collapse potential of the manufactured concrete

Author(s): Varadharajan Srinivasan and Kirthanashri Srinivasan

Abstract

India is very rich in metals and minerals and states like Rajasthan have large number of metal industries which generates Imperial smelting furnace slag (ISF) in enormous quantity and already a enormous quantity of ISF is stockpiled due to disposal issues.ISF contains hazardous materials like lead and Zinc needs to be immediately disposed for environmental safety. The rapidly increasing construction activities has increased generation of waste materials like marble waste powder (WMP) and Construction & demolition waste ( C & D waste). These materials poses disposal issues due to non biodegradability and toxic nature. The stockpiling of enormous quantities of these wastes could be a serious environmental threat in the coming decade. This research work addresses this aspect by replacing fine aggregate with a combination of ISF slag and WMP in percentage varying from 0 % to 20 %, and replacing coarse aggregates by C &D waste by 20 %. The second aim is to analytically model the manufactured concrete using experimental test results for assessment of seismic vulnerability. To achieve this 300 RC building frames made with ISF slag concrete were modeled and analyzed in E-Tabs software and we subjected to an ensemble of 100 ground motions. The review of seismic design codes shows that material composition and irregularity is not considered in proposing rules to estimate seismic behavior. The authors are proposing a new index to determine the same. The proposed index is used to frame new design methodologies for buildings made with ISF slag concrete. Finally this paper aims to assessment the environmental benefit of incorporating the industrial wastes in concrete.

Article Title: Sustainable innovative approach for eternal data

Author(s): Pierluigi Calabrese,Giuseppe Stella and Michele Di Lecce

Abstract

The paper shows an innovative approach to preserving the memory of historical archives using the potential offered by the Web3. This approach, in fact, by making use of the InterPlanetary File System (IPFS) protocol, makes it possible to ensure the availability of historical data without the risk of losing access to the same due to hosting renewals not done or unavailable servers. This approach is therefore revolutionary for historical archives of institutions and associations and also for ensuring transparency of records. This approach thus meets the sustainability goals of the UN 2030 Agenda on Innovation (9) and Justice (16). Moreover, together with the encryption applied to it (with keys also saved in IPFS) the approach turns out to ensure a good level of confidentiality as well. Both the level of availability and confidentiality are estimated through rigorous mathematical approach that takes into account the number of nodes in the IPFS detected by crawler at a given time.
