TL;DR: The importance of the design process, its principles and the challenges of sustainable packaging are also summarized in this paper, and it can be concluded that scientists, designers and engineers all are necessarily required to contribute towards research in order to commercially exploit cellulose nanofiber for sustainable packaging.
Abstract: The demand for exploring advanced and eco-friendly sustainable packaging materials with superior physical, mechanical and barrier properties is increasing. The materials that are currently used in packaging for food, beverage, medical and pharmaceutical products, as well as in industrial applications, are non-degradable, and thus, these materials are raising environmental pollution concerns. Numerous studies have been conducted on the utilization of bio-based materials in the pursuit of developing sustainable packaging materials. Although significant improvements have been achieved, a balance among environmental concerns, economic considerations and product packaging performance is still lacking. This is likely due to bio-based materials being used in product packaging applications without a proper design. The present review article intends to summarize the information regarding the potential applications of cellulosic nanofiber for the packaging. The importance of the design process, its principles and the challenges of design process for sustainable packaging are also summarized in this review. Overall it can be concluded that scientists, designers and engineers all are necessarily required to contribute towards research in order to commercially exploit cellulose nanofiber for sustainable packaging.

TL;DR: In this article, the authors reviewed the extraction of cellulose nanoparticles from conventional and non-conventional lignocellulosic biomass, and the preparation of cellulosic nanocomposites for food packaging.
Abstract: The extensive use of petroleum-based synthetic and non-biodegradable materials for packaging applications has caused severe environmental damage. The rising demand for sustainable packaging materials has encouraged scientists to explore abundant unconventional materials. For instance, cellulose, extracted from lignocellulosic biomass, has gained attention owing to its ecological and biodegradable nature. This article reviews the extraction of cellulose nanoparticles from conventional and non-conventional lignocellulosic biomass, and the preparation of cellulosic nanocomposites for food packaging. Cellulosic nanocomposites exhibit exceptional mechanical, biodegradation, optical and barrier properties, which are attributed to the nanoscale structure and the high specific surface area, of 533 m2 g−1, of cellulose. The mechanical properties of composites improve with the content of cellulose nanoparticles, yet an excessive amount induces agglomeration and, in turn, poor mechanical properties. Addition of cellulose nanoparticles increases tensile properties by about 42%. Barrier properties of the composites are reinforced by cellulose nanoparticles; for instance, the water vapor permeability decreased by 28% in the presence of 5 wt% cellulose nanoparticles. Moreover, 1 wt% addition of filler decreased the oxygen transmission rate by 21%. We also discuss the eco-design process, designing principles and challenges.

TL;DR: The ultimate goal of this research was to advance manufacturing and production system development to being guided by engineering science and design rather than the common practice of duplicating another person's or entity’s notion of the best physical implementation.
Abstract: The focus of this paper is on the use of the Manufacturing System Design Decomposition (MSDD) to make effective cost and production system design decisions. A comparative study is conducted to illustrate how and why the total cost is reduced when the functional requirements defined by the MSDD are achieved. The ultimate goal of this research was to advance manufacturing and production system development to being guided by engineering science and design rather than the common practice of duplicating another person’s or entity’s notion of the best physical implementation.

TL;DR: In this article, the application of Axiomatic Design to large complex systems is discussed, including quantitative measures of life cycle properties, design of cyber-physical systems, and design of hetero-functional networks.
Abstract: Since its first publication in 1978, Axiomatic Design has developed to become one of the more commonly applied engineering design theories in the academic literature and industrial practice. In parallel, model-based systems engineering (MBSE) has developed from industrial origins in the aerospace, communications, and defense sectors. As the scope of humanity’s engineering efforts grows to include evermore complex engineering systems, the engineering design methodologies that guide these efforts must also develop. These two, now well-established but independently developed, engineering design methodologies now appear well poised to support the synthesis, analysis, and resynthesis of large complex engineering systems. As the first chapter in this book on the application of Axiomatic Design to large complex systems, it introduces the fundamentals of Axiomatic Design within the context of engineering systems and as a conceptual foundation for subsequent chapters. It also relates Axiomatic Design’s key concepts and terminology to those found in current MBSE techniques including SysML. The chapter concludes with applications in which Axiomatic Design has served to advance the development of engineering systems including quantitative measures of life cycle properties, design of cyber-physical systems, and design of hetero-functional networks.

TL;DR: This article presents a novel method that allows problems involving design coupling to be described by their attributes using the basic concepts of Extenics, enabling the decoupling process to be general, structured and effective in search for the knowledge needed for solving the coupling problem.
Abstract: Proper design decoupling in the context of Axiomatic Design (AD) is essential to transforming customer needs to functional requirements, design parameters, and process variables using matrices. It is common that design decoupling is performed by adopting methods that are philosophically and methodologically different from AD, such as TRIZ. However, transformation of coupling problems following the approach lacks a uniform description for design coupling and also a systematic methodology for decoupling. This article presents a novel method that allows problems involving design coupling to be described by their attributes using the basic concepts of Extenics. The resulted descriptions are well-defined in the basic-element form with a set of uniform characteristics, enabling the decoupling process to be general, structured and effective in search for the knowledge needed for solving the coupling problem. Three decoupled models each exploring AD and Extenics for following a particular decoupling direc...
