3D Printing to Produce BioComposite
Current environmental concerns have led to a search of more environmentally friendly manufacturing methods, thus, natural fibers have gained attention in the 3D printing industry to be used as biofilters along with thermoplastics. The utilization of natural fibers is very convenient as they are easily available, cost-effective, eco-friendly, and biodegradable. Using natural fibers rather than synthetic fibers in the production of the 3D printing filaments will reduces gas emissions associated with the production of the synthetic fibers that would add to the current pollution problem. As a matter of fact, natural fibers have a reinforcing effect on plastics. This review analyzes how the properties of the different types of polymers vary when natural fibers processed to produce filaments for 3D Printing are added. The results of using natural fibers for 3D Printing are presented in this study and appeared to be satisfactory, while a limited number of studies have reported some issues.

A Blockchain Prototype on Container Shipping Operations
Blockchain technology has been proposed as a solution to these concerns. It is a decentralised ledger system that can record and track transactions in a secure and transparent manner. Moreover, it is possible to create a tamper-proof record of the container’s movements and status throughout the shipping process using blockchain to record the data from e-seals.

A Product/Service System
Product/service system (PSS) is widely considered as a promising design object with the potential to enhance environmental sustainability of industrial solutions. The state of the art of PSS design research includes several prescriptive PSS design support tools, methods and procedures. This body of literature has been extensively reviewed in the past. However, there is a lack of consolidation of the available prescriptive knowledge in a condensed and practically useful format that can be used by practitioners to guide their conceptual PSS design activities and by researchers to build their work on. Thus, to address this gap in our knowledge, we use an intra-disciplinary literature analysis and meta-synthesis approach to consolidate the extant prescriptive PSS design knowledge in the form of a schema for conceptual PSS design.

Abrasive Water-Jet Machining
Abrasive water jet machining (AWJM) is a very useful non-conventional machining for the cutting of dissimilar materials at once. It is a flexible process that generates low thermal damage to the machined surface as there is no continuous tool-material con- tact along the machining process. Compared to conventional processes such as milling, abrasive particles are used in water jet machining. These particles have cutting edges that allow the machining of the material by overlapping of small impacts that deform the material. At each instant, a quantity of abrasive particles travels in the water jet in order to perform the cut.

Achieving Sustainability in Solar Energy Firms in Turkey
Lean principles and sustainability are considered important terms in business. Solar firms are witnessing great competition to fulfill energy requirements, suffering from a huge amount of waste, negatively affecting the sustainability dimensions. Thus, the aim of the study is to build a framework for solar energy firms to achieve sustainability through adopting lean principles, which will help to fix many problems as waste and costs. The method included reviewing the literature to explore the founding of the relation between the two terms, and using a questionnaire that was directed to the responsible people in Turkish solar energy firms. The results of the survey were analyzed to: (1) Find out what the responsible people think about the two terms lean and sustainability; (2) Measure the probable relationship between lean principles and sustainability dimensions by applying a linear regression test; (3) Use the results of point number two to build the framework. The result showed there was a high level of relative importance about the two terms from the point of view of managers and experts in solar firms. In addition, the study found a relationship between adopting pull and flow principles of lean, and achieving economic and social dimensions of sustainability, this finding is represented in a framework.

Acoustic Technology in Food Processing
Acoustic technology is characterized as environmentally friendly and is considered an alternative method due to its sustainability and economic efficiency. This technology provides advantages such as the intensification of processes, increasing the efficiency of processes and eliminating inefficient ones, improving product quality, maintaining the product’s texture, organoleptic properties, and nutritional value, and ensuring the microbiological safety of the product.

Additive Manufacturing and Circular Economy
Additive Manufacturing (AM), also known as three-dimensional (3D) printing has emerged as a disruptive and powerful tool for industrial systems in the Industry 4.0 era by helping businesses flourish in the contemporary dynamic competitive landscape. However, their achievements and development highly rely on “take-make-waste” linear business models, which come, all too often, to the detriment of the environment. Hence, a shift to Circular Economy (CE) practices promoting the acceleration of the transition to resource-efficient systems and the minimization of environmental degradation is now more imperative than ever.

Additive Manufacturing in Automotive Sector
Triple bottom line (3BL) approaches to sustainable supply chain management (SSCM) often involve trade-offs between their three dimensions (economic, environmental, and social). Under some circumstances, however, synergic approaches (typically involving disruptive innovations) might allow simultaneous improvement in one or more dimensions without compromising the others. This entry analyzes one such case: the potential of properly designed additive manufacturing approaches in the automotive spare parts industry to simultaneously boost profits and reduce environmental impact.It is based on the systematic analysis of the real spare parts business of a mid-size automotive brand in Spain. Its results suggest that such synergic, self-reinforcing opportunities do indeed exist, and might even be further developed by  strategically integrating sustainability constituents, while completely changing the current spare parts' business model.
