Fashion and textile industry has confronted to participate with the sustainable industry and society proactively not by the government regulations, but by the shareholders or consumers driven with corporate social responsibility. The purpose of this paper is to consider methods applied for the sustainability of products according to Korean domestic fashion and textile companies and clothing types and to investigate the limitation of current sustainability methods of companies.

The study used document analysis and case studies of 396 companies. The study looked into newspapers, monthly magazines, and publications of fashion companies and internet web sites of almost every possible type that have been issued to date and analyzed the previous studies as well.

The companies’ strategies are of three groups, the uses of environmental friendly materials: 36.9 percent (natural fibers, recycled fibers and biodegradable fibers), apparel reuse: 4.5 percent (remodeling/alteration and transform/combination with more materials), and eco-marketing promotions: 58.6 percent. For women’s and casual wear section, the methods used with organic materials and the green-campaign messages appeared frequently, while in the men’s wear section, coolMapsi, 0or warm OnMapsi for business wear did a lot for the low indoor energy consumption, such as no neck-tie in the hot season or wearing underwear in the cold season.

Fashion and textile products have provided the key solutions for the generation’s happiness, identity, value, self-realization, health and role. There have been the low quality and similarity of fashion products from mass production and high speed and we should consider sustainability for the next generation and society. But the current problem in the industry is that most of eco-product developments are only short term. Also, from the high cost of eco materials and processes, there is a limited portion of sustainability section among total products and low design quality of fashion or the low profit outcomes.

A mathematical model for sustainable optimization is presented. The sustainability parameters are linked to end-of-life considerations in product design and development. The sustainability considerations such as total embodied energy, eco-materials selection, CO₂ emission, cost savings due to recycling and reuse including the water savings are presented for helical compression springs used in mattresses.

The utilisation of market-based approaches (MBAs) than command-control approaches (CCAs) is still at the embryonic stage to stimulate the green behaviour of small and medium-sized enterprises (SMEs) in developing economies. The study aims to elucidate the association between environmental incentives (EIs), green responsiveness (GR) and environmental performance (EP).

A quantitative dominant research design is adopted with qualitative support. The study model is developed by integrating legitimacy theory (LT) and the natural resource-based view (NRBV). The cross-sectional data were gathered from the upper echelon of 395 SMEs in Sri Lanka, and 10 subsequent interviews were conducted. The partial least squares approach of structural equation modelling (PLS-SEM) was used to evaluate the hypothesised relationships.

The results found evidence to demonstrate that EIs positively link with GR and EP and GR mediates this association. Further, the study revealed that although MBAs are established, the SME sector is less aware of EIs such as tax concessions, tax reliefs, low interest, soft loans and discounts on eco-materials.

The results provide valuable insights to enhance environmental sustainability. The owners of SMEs should strategically use environmental inducements to overcome resource poverty to engage in green practices. The regulators and policymakers should develop the incentive policies and provide the mechanisms to disseminate the required skills and technologies to SMEs.

According to the authors' best knowledge, this is one of the pioneering empirical studies on EIs, GR and EP with mediating effects in Sri Lanka.

The selective laser melting (SLM) technique, as a typical additive manufacturing process, is widely used for the fabrication of metallic biomedical components. In terms of biodegradability, zinc and its alloys represent an emerging generation of metallic materials for biomedical implants. The purpose of this paper is to obtain the Zn and Zn10Mg alloys with high mechanical properties using the SLM technology. The relationship between the processing parameters and the porosity of pure Zn and Zn10Mg alloy samples was investigated.

The samples were fabricated using SLM technology working in an inert gas closed chamber. Preliminary experiments were conducted to analyze the laser power and gas flow on evaporation, single track form and porosity. To evaluate the influence of factors on relative density, the response surface methodology was applied.

The satisfactory results of the proposed method were achieved, in which the relative density of the components reached up to 99.63%, and compression strength reached 214 ± 13 MPa under optimal processing conditions.

Zinc is categorized by its low melting and boiling point, which leads to the high porosity of the components. It is difficult to prepare the Zn alloy samples with high relative density using SLM technology. This work successfully achieved dense Zn and Zn10Mg samples and investigated their microstructure, mechanical properties and corrosion behavior.

The purpose of this paper is to propose a novel method to prepare pure Ti powder for 3D printing with tailorable particle size distribution.

The main procedures of the present method consist of gas state reaction to synthesize TiH₂ nanoparticles, agglomeration to obtain micronscale powder particles by spray drying, and densification of particle interior by heat treatment.

The prepared Ti powder has a specific bimodal particle size distribution in a range of small sizes, good sphericity and high flowability. Particularly, this new technique is capable of controlling powder purity and adjusting particle size.

To the best knowledge of the authors, the approach for preparing 3D printing metallic powders from nanoparticles has not been reported in the literature so far. This work provides a novel method that is particularly applicable to prepare 3D printing metallic powders which have small initial particle sizes and high reactivity in the air.

Cuba has recently endured the impact of hurricanes Lili (1996), George (1998), Irene (1999), Michelle (2001), Isidore (2002), Lili (2002), Charlie and Ivan (2004). The provinces of Villa Clara, Matanzas and Pinar del Río have suffered the major damage, basically in coastal towns where thousands of houses have been destroyed, and families displaced from their homes.

Tackling this problem proves to be complicated. Decision-makers face two choices: (a) to concentrate the scarce resources - including post disaster aid - on emergency actions to reduce only the damages caused by the hurricane, or (b) to improve in a sustainable way existing houses through better and more efficient material supply. In both cases, the possibility of local production of building materials becomes a crucial factor.

The Centre for Investigation and Development of Structures and Materials (CIDEM) has been involved in disaster-response projects in the area since 1996. The thrust has been the manufacture of ecomaterials such as micro concrete roofing (MCR) tiles, pozzolanic cement CP-40 and hollow concrete blocks, which provide the means to build affordable and hurricane safe houses. These materials are produced on the basis of local raw materials and labour in small workshops based directly in the communities.

The widespread use of ecomaterials on the northern coast of Villa Clara province has been a key aspect in decreasing the vulnerability of the houses against hurricanes. The fact that these materials have withstood the impact of various hurricanes without significant damage has drawn the attention of local governments, communities and donors. The presentation of case studies in this paper will illustrate this experience.

The purpose of this paper is to examine the impact of green supply chain management on environmental performance (EP), operational performance (OP), and business performance in the context of a developing country, Jordan. In addition, the mediating effects of environmental and OP on the relationship between green supply chain management and business performance are investigated.

The study is based on survey data collected from 215 manufacturing firms from different industries in Jordan. Validity and reliability analyses were carried out using SPSS and Amos. Direct and indirect effects were tested using structural equation modeling.

The results revealed that green supply chain management positively and significantly affects both EP and OP. The results also demonstrated that the total effect of green supply chain management on business performance is positive and significant. The direct effect of green supply chain management on business performance proved to be negative, but insignificant. Thus, the total positive effect of green supply chain management on business performance is indirect and fully goes through EP and OP.

This study is one of the first to examine the direct and indirect effects of green supply chain management on business performance, especially in a developing country and the Middle East in particular. Furthermore, this study contributes to the existing body of knowledge by investigating the mediating effects of EP and OP on the green supply chain management and business performance relationship.
