This study aims to assess the effect of water variation on bioethanol production from cassava peels (CP) using Saccharomyces cerevisiae yeast as the ethanologenic agent.

Abstract

Purpose

This study aims to assess the effect of water variation on bioethanol production from cassava peels (CP) using Saccharomyces cerevisiae yeast as the ethanologenic agent.

Design/methodology/approach

The milled CP was divided into three treatment groups in a small-scale flask experiment where each 20 g CP was subjected to two-stage hydrolysis. Different amount of water was added to the fermentation process of CP. The fermented samples were collected every 24 h for various analyses.

Findings

The results of the fermentation revealed that the highest ethanol productivity and fermentation efficiency was obtained at 17.38 ± 0.30% and 0.139 ± 0.003 gL−1 h−1. The study affirmed that ethanol production was increased for the addition of water up to 35% for the CP hydrolysate process.

Practical implications

The finding of this study demonstrates that S. cerevisiae is the key player in industrial ethanol production among a variety of yeasts that produce ethanol through sugar fermentation. In order to design truly sustainable processes, it should be expanded to include a thorough analysis and the gradual scaling-up of this process to an industrial level.

Originality/value

This paper is an original research work dealing with bioethanol production from CP using S. cerevisiae microbe.

Highlights

  1. Hydrolysis of cassava peels using 13.1 M H2SO4 at 100 oC for 110 min gave high Glucose productivity

  2. Highest ethanol production was obtained at 72 h of fermentation using Saccharomyces cerevisiae

  3. Optimal bioethanol concentration and yield were obtained at a hydration level of 35% agitation

  4. Highest ethanol productivity and fermentation efficiency were 17.3%, 0.139 g.L−1.h−1

Abstract

Purpose

The purpose of this study is to predict family takāful purchase intentions (FTPIs) using an extended theory of planned behavior (TPB) with relevant mediating and moderating factors.

Design/methodology/approach

This study is based on a survey of 384 Muslim employees who work in both government and private organizations. This study used partial least square structural equation model (PLS-SEM) for hypothesis testing, predictive relevance and measuring the effect size of the model.

Findings

The study found that attitude (ATT), subjective norms (SN), perceived behavioral control (PBC), saving motives (SM), promotional campaign (PC) and religiosity (RG) directly contribute to the prediction of FTPIs. Furthermore, ATT and SM partially mediate between PC and FTPI. Moreover, RG significantly moderates the association between ATT, SN, SM and FTPI, while RG insignificantly moderates the link between PBC and FTPI.

Practical implications

This study provides insight into understanding the factors leading to an enhanced understanding of FTPI in a country where the industry is growing very fast. Further, the study suggests informative and persuasive promotions to encourage FTPI in Bangladesh and similar countries.

Originality/value

This study provides insights into previously unaddressed FTPI among Muslim employees in Bangladesh and similar countries. Prior work on determining FTPI has not focused on promotional campaigns and saving motives, and thus, this study has extended TPB to understand the phenomenon.

Abstract

Purpose

The objective of this study is to investigate the barriers hindering the integration of lean manufacturing (LM) practices within the furniture industry of Bangladesh. The traditional operational paradigms in this sector have posed substantial challenges to the effective implementation of LM. In this study, the barriers of implementing LM in the furniture business are examined, aiming to provide a systematic understanding of the barriers that must be addressed for a successful transition.

Findings

The research reveals that “Fragmented Industry Structure,” “Resistance to Lean Practices” and “Inadequate Plant Layout and Maintenance”, emerged as the foremost barriers to LM implementation in the furniture industry. Additionally, “Insufficient Expert Management,” “Limited Technical Resources” and “Lack of Capital Investment” play significant roles.

Research limitations/implications

The outcomes of this study provide valuable insights into the furniture industry, enabling the development of strategies for effective LM implementation. One notable challenge in lean implementation is the tendency to revert to established practices when confronted with barriers. Therefore, this transition necessitates informed guidance and leadership. In addition to addressing these internal challenges, the scope of lean implementation should be broadened.

Originality/value

This study represents one of the initial efforts to systematically identify and assess the barriers to LM implementation within the furniture industry of Bangladesh, contributing to the emerging body of knowledge in this area.
