An empirical study of green supply chain management practices amongst UK manufacturers

Purpose: The purpose of this paper is to examine the extent and nature of greening the supply chain (SC) in the UK manufacturing sector; and the factors that influence the breadth and depth of this activity.

Design/methodology/approach: Based on the findings from a sample of manufacturing organisations drawn from the membership of The Chartered Institute for Purchasing and Supply. Data are collected using a questionnaire, piloted and pre-tested before distribution with responses from 60 manufacturing companies.

Findings: On average manufacturers perceive the greatest pressure to improve environmental performance through legislation and internal drivers (IDs). The least influential pressures are related to societal drivers and SC pressures from individual customers. Green supply chain management (GSCM) practices amongst this “average” group of UK manufacturing organisations are focusing on internal, higher risk, descriptive activities, rather than proactive, external engagement processes. Environmental attitude (EA) is a key predictor of GSCM activity and those organisations that have a progressive attitude are also operationally very active. EA shows some relationship to legislative drivers but other factors are also influential. Operational activity may also be moderated by organisational contingencies such as risk, size, and nationality.

Research limitations/implications: The main limitation to this paper is the relatively small manufacturing sample.

Practical implications: This paper presents a series of constructs that identify GSCM operational activities companies to benchmark themselves against. It suggests which factors are driving these operational changes and how industry contingencies may be influential.

Originality/value: This paper explores what is driving environmental behaviour amongst an “average” sample of manufacturers, what specific management practices take place and the relationships between them.

Bamboo : a distinctive green fibre

This article reports the preliminary findings on the morphology, chemical structure, antimicrobial and UV-screening properties of bamboo fibres. Bamboo fibres provide a very promising alternative to other natural fibres by virtue of their distinctive characteristics such as eco-friendly farming, inherent antimicrobial, UV-protective and highly· breathable properties. However, these novel properties are moslly claimed by fibre manufacturers, with little scientific evidence.  Moreover, those properties may largely depend on the manufacturing process, which is not widely disclosed by the manufacturers, Common manufacturing processes may require the use of a large amount of chemicals which would not make the product truly eco-friendly. Therefore, there is a strong need for unbiased laboratory experiments being conducted in a rigorous manner to elucidate the origin of those unique properties of bamboo fibres and to develop new processing methods to effectively utilise the properties in the final products. This research is aimed to prove the unique characteristics of bamboo fibres scientifically and to develop an efficient manufacturing process, in order to establish the place of bamboo fibres as a novel green material.

Production of green nanomaterials

While our awareness towards sustainable society and environment grows, the importance of ‘green’ materials and manufacturing is gaining significant recognition. We have demonstrated that naturally-occurring fibers as renewable raw materials can be converted into nanoparticles and nano fibers using simple top-down methods without introducing hazardous chemicals. This new class of green nanomaterials will have a wide range of environmental and biomedical applications owing to the inherent biocompatible, biodegradable and carbon-neutral nature.

An evaluation of the role of green marketing and a firm's internal practices for environmental sustainability

The management of a firm's green operations is increasingly important for marketing strategists. The purpose of this study is to investigate the cross-influences of green marketing strategy and the key internal green functional areas in a firm. We use the antecedents of marketing strategy and identify relationships between green marketing strategy and key supporting internal environmental operations of firms with respect to (1) green suppliers, (2) environmental resource management, (3) green research and development, and (4) environmental manufacturing processes and procedures. The statistical techniques of parallel analysis, factor analysis and multiple regressions are used to analyze data collected from 332 firms. The results identify that among the four functional areas of firms adopting green marketing strategy. Two are more likely to influence green marketing strategy – supplier selection and research and development. Implications are discussed. The findings contribute to the theory of green marketing strategy. Future research is recommended.

Effect of green machining on distortion and surface finishing in advanced ceramic

An alternative for grinding of sintered ceramic is the machining on the green state of the ceramic, which presents easy cutting without the introduction of harmful defects to its mechanical resistance. However, after sintering there are invariably distortions caused by the heterogeneous distribution of density gradients, which are located in the most outlying portions of the compacted workpiece. In order to minimize these density gradients, this study examined the influence of different allowance values and their corresponding influence in distortion after sintering alumina specimens with 99.8 % purity by turning operation using cemented carbide tool. Besides distortion, other output variables were analyzed, such as tool wear, cutting force and surface roughness of green and sintered ceramics. Results showed a distortion reduction up to 81.4%. Green machining is beneficial for reducing surface roughness in both green and sintered states. Cutting tool wear has a direct influence on surface roughness and cutting force.

Green supply chain management in local and multinational high-tech companies located in Brazil

The objective of this article is to analyse how green supply chain management (GSCM) practices are being adopted by some high-tech companies located in Brazil. The research was conducted using the case study approach, focusing on eight companies that are representative of this sector. The main results are: (a) the most adopted GSCM practices in the studied high-tech companies located in Brazil are internal environmental management, investment recovery and reverse logistics and (b) Brazilian environmental legislation and international policies are very important in driving the adoption of GSCM practices. The internationalisation of companies was also found to be a variable that interferes with the adoption of GSCM practices. This is one of the first studies that examine the relationship between GSCM and the internationalisation of companies located in Brazil. © 2013 Springer-Verlag London.

Lean and green? Evidências empíricas do setor automotivo brasileiro

The aim of this paper is to verify whether the practices of lean manufacturing are positively associated with the adoption of environmental management practices in Brazilian companies in the automotive sector to test the hypothesis that by being lean the business tends to become green. To this purpose, a framework associating these concepts with the research hypothesis was proposed. The data collected from 75 companies were analyzed using Structural Equation Modeling. The main results show that lean manufacturing (LM) is positively associated with environmental management (EM), but the explanation power of LM over EM is considered weak/moderate. In fact, being lean also means being green, but other organizational variables not considered in this study may influence the greening of organizations.

Há sinergia entre o sistema lean manufacturing e a gestão ambiental? mapeando o estado da arte

In recent decades, two research themes have been prominent in the academic and organizational setting: lean manufacturing and green management. Since 1996, when Florida (1996) wrote an article focusing on the synergy between these two areas, the debate if “Lean is Green?” enters in the academic field. It is in this context that this research presents the results of a systematic literature on the topic, focusing on the characteristics, positive and negative impacts, lean paradigms, green paradigms and design of supply chains. To perform this procedure it were followed the methodological footsteps of Lage Junior and Godinho Filho (2010). The research occurred in the database Scopus and it was conducted from June, 2012 to July, 2012.The key word used was “green lean” and as search filter it were included only articles and conference Papers. Their main result is a deep analysis of the accumulated knowledge on the subject, where it is revealed that the majority of studies point to the synergy between some components of the lean manufacturing system in relation to environmental management. The research gap found is related to articles that address the entropy of the union of lean and green systems.

Green and competitive: empirical evidence from ISO 9001 certified Brazilian companies

There are many arguments in the literature on environmental management stating that companies that have a significant environmental performance tend to be more competitive, because environmental management tends to generate positive effects on their operational performance. Despite the fact that such arguments are widely accepted, there is little empirical evidence yet of such a relationship in manufacturing contexts that are rarely studied thus far, such as those of developing countries. The paper aims to discuss these issues. Design/methodology/approach – With the objective of testing the positive relationship between environmental performance and operational performance, this research presents the data of a survey conducted with 75 ISO 9001-certified Brazilian companies. Such data were analyzed by means of structural equation modeling. Findings – The paper discovered that, indeed, environmental management relates in a positive, significant manner and large effect to the operational performance of companies.

GREEN MACHINING ORIENTED TO DIMINISH DENSITY GRADIENT FOR MINIMIZATION OF DISTORTION IN ADVANCED CERAMICS

After sintering advanced ceramics, there are invariably distortions, caused in large part by the heterogeneous distribution of density gradients along the compacted piece. To correct distortions, machining is generally used to manufacture pieces within dimensional and geometric tolerances. Hence, narrow material removal limit conditions are applied, which minimize the generation of damage. Another alternative is machining the compacted piece before sintering, called the green ceramic stage, which allows machining without damage to mechanical strength. Since the greatest concentration of density gradients is located in the outer-most layers of the compacted piece, this study investigated the removal of different allowance values by means of green machining. The output variables are distortion after sintering, tool wear, cutting force, and the surface roughness of the green ceramics and the sintered ones. The following results have been noted: less distortion is verified in the sintered piece after 1mm allowance removal; and the higher the tool wear the worse the surface roughness of both green and sintered pieces.

Sustainable materials: The business case for green chemistry design practices

Product manufacturers face increasing environmental and human health regulations with certain regulations targeting specific chemicals of concern that must be removed from the supply chain. This study examines a green chemistry approach to choosing between flame retardant alternatives in electronic products during the design phase of product development. An aggregated score based on five criteria was generated for each flame retardant. To address subjectivity and cognitive bias concerns probabilistic sensitivity analysis was applied to the weighting factors used to generate the scores to examine the reliability of the results. The highest scoring flame retardants based on the comprehensive green chemistry approach were different from the flame retardants chosen using cost as the primary selection criteria.
