The most widely recycled plastic in the world is recycled polyethylene terephthalate (rPET). To minimize the environmental related issues associated with synthetic fibers

Abstract

Purpose

The most widely recycled plastic in the world is recycled polyethylene terephthalate (rPET). To minimize the environmental related issues associated with synthetic fibers, several researchers have explored the potential use of recycled polyester fibers in developing various technical textile products. This study aims to develop needle-punched nonwoven fabrics from recycled polyester fibers and investigate its suitability in oil spill cleanup process.

Design/methodology/approach

According to Box and Behnken factorial design, 15 different needle-punched nonwoven fabrics from recycled polyester fibers were prepared by changing the parameters, namely, needle punch density, needle penetration depth and fabric areal weight. Several featured parameters such as oil sorption, oil retention, oil sorption kinetics, wettability and reusability performance were systematically elucidated.

Findings

The maximum oil sorption of recycled nonwoven polyester is found to be 24.85 g/g and 20.58 g/g for crude oil and vegetable oil, respectively. The oil retention is about 93%–96% in case of crude oil, whereas 87%–91% in case of vegetable oil. Recycled polyester nonwoven possesses good hydrophobic–oleophilic properties with static contact angle of 138° against water, whereas 0° against crude oil and vegetable oil. The reusability test results indicate that recycled polyester nonwoven fabric can be used several times because of its reusability features.

Originality/value

There is no detailed study on the oil sorption features of needle-punched nonwoven fabrics developed from recycled polyester fibers. This study is expected to help in developing fabrics for oil spill cleanups.

Abstract

Purpose

Microfiber is one of the major sources of microplastic emission into the environment. In recent times, research on microfiber has gained momentum, and research across different disciplines was performed. However, no complete study was performed from the viewpoint of textiles to analyse the microfiber shedding behaviour by relating the properties textiles. The purpose of this paper is to analyse the microfiber shedding behaviour in textiles.

Design/methodology/approach

Articles on the microfiber shedding across different disciplines were collected and analysed systematically to identify the influencing factor. The influence of laundry parameters is found to be majorly discussed section, yet very few research data is found on the effect of yarn and fabric properties on the microfiber shedding.

Findings

Most of the articles listed laundry detergent addition, higher temperature, use of softeners, type of washing machines used and amount of liquid used as the major factors influencing the fiber shedding. Concerning the fiber and yarn characteristics, yarn twist, fiber type (staple/filament), method of production, fabric structure and specific density are reported as influencing factors. Some articles highlighted the influence of ageing of textiles on the fiber shedding.

Originality/value

The review identified the research gap in the textile sector and reports that so far, no research performed on microfiber shedding with the textile parameters. The review further urges the importance of research works to be performed in the textile by considering the fabric and yarn properties.

Abstract

Purpose

The purpose of this paper is to compare the bursting strength, bursting distension, air permeability and wale wise wicking rate properties of recycled polyester (r-PET) and virgin polyester (v-PET) raw materials from which single jersey knitted fabric samples are manufactured. Meanwhile, numerical optimization method was used in predetermined parameters to determine the optimum r-PET and v-PET blend ratio and yarn manufacturing technology. In the optimization analysis, the average values of the important yarn and fabric properties inspected were taken as a target according to the 50 percent proportion of r-PET and v-PET fiber for both compact and ring yarn manufacturing technology.

Design/methodology/approach

To encourage the use of value-added textile products produced from recycling PET bottle with the focus of social responsibility is a condition that should be evaluated within the scope of waste management. The recycling of PET bottles and finding new opportunities for the uses in different field are crucial for both contributing environmental economy and conserving natural energy resources. The most important alternative ways is to use the r-PET fiber from recycling PET bottle in textile industry. In this study, 19.7 tex r-PET/cotton and v-PET/cotton-blended compact and ring spun yarns were produced at different blending ratios at the same production parameters.

Findings

Results showed that blend type, blend ratio and yarn manufacturing technology have statistical significance effect on bursting strength and air permeability. Besides, it was found that blend type has no significance on wale wise wicking rate unlike other parameters. Optimization analysis indicated that single jersey knitted fabric with v-PET/CO 58.62/41.38 percent compact yarn had higher desirability with the value of 0.72.

Originality/value

At the present time, r-PET fiber is blended in small amount (approximately 5–15 percent blend ratio) with both cotton and polyester together. In addition, it is possible using different fiber blend types instead of cotton and polyester according to the usage area. The most important question is to determine the amount of r-PET proportion. In other words, both optimum yarn/fabric quality parameters should be ensured and at the same time life cycle of the apparels should not be short when the optimum r-PET proportion is taken into consideration.

Abstract

Purpose

This paper aims to characterize and develop a new ecological lightweight concrete reinforced by addition of palm plant fibers (from vegetal waste) to be used in the thermal and acoustical insulation of local constructions. The date palm plant fibers are characterized by their low sensitivity to chemical reactions, low cost and large availability in local regions. Therefore, the newly obtained lightweight concrete may suggest a great interest, as it seems to be able to achieve good solutions for local construction problems, technically, economically and ecologically.

Design/methodology/approach

The experimental program focused on developing the composition of palm-fiber-reinforced concrete, by studying the effect of the length of the fibers (10, 20, 30 and 40 mm) and their mass percentage (0.5%, 1%, 1.5% and 2%), on the mechanical and acoustical properties of the composite. The main measured parameters were the compressive strength and flexural strength, sound absorption coefficient, noise reduction coefficient (NRC), etc. These tests were also borne out by the measure of density and water absorption, as well as microstructure analyses. To fully appreciate the behavior of the material, visualizations under optical microscope and scanning electron microscope analyses were carried out.

Findings

The addition of plant fibers to concrete made it possible to formulate a new lightweight concrete having interesting properties. The addition of date palm fibers significantly decreased the density of the concrete and consequently reduced its mechanical strength, particularly in compression. Acceptable compressive strength values were possible, according to the fibers content, while better values have been obtained in flexion. On the other hand, good acoustical performances were obtained: a considerable increase in the sound absorption coefficient and the NRC was recorded, according to the content and length of fibers. Even the rheological behavior has been improved with the addition of fibers, but with short fibers only.

Originality/value

Over the recent decades, many studies have attempted to search for more sustainable and environmentally friendly building materials. Therefore, this work aims to study the possibility of using waste from date palm trees as fibers in concrete instead of the conventionally used fibers. Although many researches have already been conducted on the effect of palm plant fibers on the mechanical/physical properties of concrete, no information is available neither on the formulation of this type of concrete nor on its acoustical properties. Indeed, due to the scarcity of raw materials and the excessive consumption of energy, the trend of plant fibers as resources, which are natural and renewable, is very attractive. It is therefore a major recycling project of waste and recovery of local materials.

Abstract

Purpose

The purpose of this paper is to present an original model for the production-recycling-reuse of plastic beverage bottles.

Design/methodology/approach

It is assumed that discarded two-liter plastic polyethylene terephthalate (PET) bottles are collected from the market. The bottles are then sorted into non-contaminated and contaminated streams. The non-contaminated PET bottles are either remanufactured or used as regrind mixed with virgin PET to produce new bottles to satisfy varying demand. The contaminated bottles are either sold to industries using low-grade plastic or disposed of in a landfill. Numerical studies are used to illustrate the behaviour of the model, with an emphasis on exploring the reduction of total system cost and the amount of bottles going into a landfill.

Findings

Numerical analyses conducted on the model found that the amount of bottles collected had the largest influence on the outcome of the total system unit time cost. Alternative materials to PET are surveyed and used to demonstrate a significant reduction in the cost of landfill disposal due to their more rapid degradation in the landfill.

Research limitations/implications

Several areas for future work are highlighted. Potential modifications to the model could focus on accommodating bottles made of material other than plastic, incorporating the effects of learning on manual tasks, and on accommodating shortages or excess inventory.

Originality/value

The model incorporates several unique aspects, including accounting for the cost of land use and associated environmental damage through the calculation of a present value that is charged to the manufacturer.

Abstract

Purpose

This paper reviews the literature on environmentally sustainable practices in textile, apparel and fashion (TAF) industries to allow the mapping of practices across various manufacturing processes and the development of a conceptual framework to guide investigation of the extent of sustainable practices in TAF industries from an environmental perspective.

Design/methodology/approach

A systematic literature review was undertaken, consisting of bibliometric and content analysis of 91 articles published in peer-reviewed journals over a 10-year period.

Findings

The inclusion of sustainable practices from all manufacturing stages in this review illustrates the diversity and complexities of environmental practices in TAF contexts. However, there is less research in developing country contexts, where most TAF production takes place and a paucity of research in upstream stages of garment washing and dyeing, and the manufacture of trims, accessories and packaging.

Research limitations/implications

The focus is on environmental sustainability and upstream manufacturing processes. The review includes literature in the form of academic journal articles from selected databases during the period January 2010–June 2020.

Practical implications

This review provides academics with a unified depiction of environmentally sustainable practices to stimulate further scholarly research and provides guidance for managers to develop firm sustainability competency by summarising best practices at different manufacturing stages

Originality/value

This review comprehensively maps the academic literature on environmentally sustainable practices in TAF industries from an upstream manufacturing operations context. It highlights the contribution of scholarly study to the knowledge base on environmentally sustainable practices in TAF industries.

Abstract

Purpose

Recycled fibres used as reinforcements are obtained from garment cut wastes of cotton, polyester and cotton/polyester fabrics to develop these composites. These composites are developed by using Epoxy resin, Kaolinite, Polypropylene sheet as matrices. Reinforcements and matrices have been used in different compositions and combinations to develop these composites. The main advantages of this type of composites are to combine the different properties of different materials to obtain unique and high-performance material.

Design/methodology/approach

Garment cut wastes from apparel industries are used for various applications in various industries. Normally, garment cut wastes and recycled fibres from garment cut wastes are used in textile, furniture, carpet, paper, automobile, construction and agricultural industries in low mechanical performance applications. In this research, composites are developed by using recycled fibres obtained from garment cut wastes as reinforcement and with different types of matrices.

Findings

Technical properties like thickness, mass per unit area, Tensile strength, Flexural strength, Impact strength, Water absorbency and Scanning Electron Microscope of developed composites were tested and analyzed. The outcome of the results demonstrates that many of the composite proportions with different blend, reinforcement and matrcies show superior mechanical performances when compared with each other, and it can be recommended for many potential applications.

Originality/value

The properties of composites are dependent on the different blend proportions of recycled fibres with reinforcement and matrices. Based on the result of tensile strength, polyester/cotton fibre reinforced composites show superior strength compared to other recycled fibre reinforced samples and it can be suitably tailored further by appropriate design of different lay-up angle and orientation with the number of different preformed layers of reinforcements to suit the intended applications.

Subject Area

Strategic Management, Business Ethics.

Study Level

This case is suitable to be used in advanced undergraduate and MBA/MSc level.

Case Overview

The case accentuates the challenges faced by Geetanjali Woollens in its mechanical recycling business which is proving detrimental to its African business expansion plans. The case is developed from the episodes of divergence in January 2018 when the buyers’ non-acceptance of mechanically recycled products initiated a managerial dilemma between “business sustenance” and “sustainable business” for Geetanjali Woollens. Being associated with the recycling business for more than 25 years, Madhukar Ghosh, the General Manager at Geetanjali Woollen recycling unit, was delving upon practical, supply-chain-wide solutions to generate standard acceptance norms for mechanically recycled textiles. For him, ethical purpose of business existence was equally important as the profit motive. Bringing operational clarity and standardized regulatory framework still seemed a big challenge for international policymakers and torchbearers of environmental responsibility, and Governments and NGOs popularizing green initiatives. Lack of policy guidelines for business behavior was exacerbating the business functioning. Madhukar knew that consistent buyer policies and standard regulatory framework could clear some mist and induce maturity in the concept of circular economy. Some formalizations were expected till the end of December 2018, if the deadlines did not get pushed further.

Expected Learning Outcomes

The objectives of this case are as follows:

  • to highlight the limitations that recycled apparel and textile products have and the concerns that emerge for buyers, designers, and consumers, due to these limitations;

  • to highlight the myopic business vision with which the recycling business is suffering due to the lack of a formalized regulatory framework, which in turn is creating various system barriers and making recycling business an unattractive proposition;

  • to appreciate the contribution of mechanical recycling of post-consumer textile waste as a closed-loop manufacturing technique in recouping the eco-impacts of increased disposal of apparel and textile products; and

  • to promote discussions for innovative solutions for limitations and concerns related to substances of concern in the recycling business and deliberations for a more effective tracking of such substances to facilitate buyer acceptance of mechanically recycled products.
