  • Asian Case studies on Circular Economy A Literature Review   Order a copy of this article
    by Rohit Panchal, Anju Singh 
    Abstract: Circular economy (CE) is an opportunity to change the industrial system suffering from the pressure of undesirable waste and resource scarcity. In recent years scholars have come up with insightful cases in this area, but analysis of cases on CE of an Asian region is very limited. The assessment of CE cases in Asia across different sectors, regions, countries via different cycles was done in this study to comprehend the trends. Therefore, a literature review of CE case studies in the Asian region was carried out from 2008 to 2019. The case studies were chosen from relevant company websites, articles, reports, and Circular Asia platform. The most popular method to close the CE loop includes recycling. Importantly, while much work has been done on the technical cycle of CE, future work could look at identifying ways to close the biological cycle of the CE.
    Keywords: Circular economy; Asia; Case Study; Resource Recovery; Recycling; Reuse.

  • Influence and relation of sustainability drivers in footwear manufacturing firms using structural equation modeling   Order a copy of this article
    by Jayakrishna K, Aravind Raj S 
    Abstract: Contemporary manufacturing firms are now in the transition from conventional manufacturing practices into sustainability practices. These firms often find it difficult in dealing with the drivers of sustainability and understanding their effects. The objective of this research work is to bridge this gap and to find out the influence of social, economic and environmental drivers on SM. Along with this, the effects on modest competencies like cost reduction, improving production rate were estimated using Structural Equation Modeling (SEM). The study was conducted in a foot wear manufacturing firm, where environmental and social impact plays a key role towards imbibing sustainability using a systematic approach based on the enablers and drivers of sustainability. A theoretical model was developed and validated using covariance based structural modeling approach in AMOS. The results obtained showed that, positive influence of sustainable drivers over the competitive proficiencies of a footwear manufacturing company.
    Keywords: Sustainable Manufacturing; Sustainable practices; Structural Equation Modeling; Validation and Estimation; Competitive proficiencies.

  • Performance of binary and ternary blends of gasoline, pyrogasoline and ethanol in spark ignition engines   Order a copy of this article
    by Luís Durão, Joaquim Costa, Margarida Gonçalves, F.P. Brito, Jorge Martins 
    Abstract: The present work aimed to study the performance of binary and ternary blends of gasoline, pyrogasoline and ethanol in a spark ignition (SI) engine. Pyrogasoline was obtained by simple distillation of a pyrolysis bio-oil produced from used cooking oil and had a LHV of 39.4 MJ.kg1. Performance tests were done in a SI engine comparing gasoline blended with 10 wt.% pyrogasoline, 10 wt.% ethanol and a mixture of 5 wt.% pyrogasoline + 5 wt.% ethanol with conventional gasoline as a standard fuel. The effect of fuel composition in engine performance parameters (torque, energy consumption and efficiency) was evaluated. Results indicate that pyrogasoline may be used as a gasoline additive, as an alternative or complement of ethanol, contributing to increase the fraction of renewable advanced fuels used.
    Keywords: used cooking oil; UCO; pyrolysis bio-oil; pyrogasoline; ethanol; spark ignition engine.

  • Clean-up treatments for syngas obtained by gasification of coal, lignocellulosic biomass or municipal residues   Order a copy of this article
    by Octavio Alves, Eliseu Monteiro, Paulo Brito, Maria Goncalves 
    Abstract: This work provides a brief overview on methodologies for the decontamination of product gas originated from the gasification of coal, lignocellulosic biomass wastes, and municipal wastes. Both conventional and emerging decontamination methods are addressed and evaluated in terms of performance and costs. Several gas decontamination strategies were identified and ranged from pre-treatments (adjustment of gasification parameters) to post-treatments (cyclones, filters, scrubbers and catalysts, for instance). A significant effort was devoted to the development of new catalyst- and sorbent-based technologies, as well as of new chemical and thermal reactors, which were able to optimise process costs, material lifetime, or the removal of a wide range of gaseous contaminants. Further investigations were recommended to be conducted in gas preparation for fuel cells, plasma converters and co-gasification with new waste mixtures. Therefore, product gas decontamination assumes a relevant role in compliance with legislation, environmental equilibrium and gasification efficiency.
    Keywords: syngas; product gas; pollutant; decontamination; gasification.

  • THERMAL DEGRADATION ANALYSIS OF LIGHT, MEDIUM AND SEVERE TORREFACTION OF OIL PALM PLANTATION RESIDUE   Order a copy of this article
    by Saidatul Shima Jamari, Yu Xun Teo, Mohd Faizal Ali 
    Abstract: Oil palm plantation waste is a potential renewable energy resource in terms of energy security and carbon-neutral fuel. The waste from the plantation sites, such as oil palm fronds (OPF) and oil palm trunks (OPT) is currently underutilised. In this work, the thermal degradation behaviour of the OPF and OPT, and evaluation on the kinetic and activation energy of the torrefied products are investigated. The samples undergo light (200?C), mild (250?C), and severe (300?C) torrefaction for 30 minutes in inert condition. Then, the samples are characterized using bomb calorimeter, FTIR, and TGA analyses. As a result, the calorific values of OPF and OPT improved to 22.46 MJ/kg and 25.48 MJ/kg from the raw samples. At mild torrefaction, the energy yield of the solid product was higher for both OPF and OPT. In conclusion, the mild condition process showed optimum characteristics for both OPT and OPF as the feedstock for energy application.
