Recycling Techniques

In the present study, a holistic End-of-Life (EoL) Index is introduced to serve as a decision support tool for choosing the optimal recycling process among a number of alternative recycling techniques of CFRP waste. For the choice of the optimal recycling process, quality of the recycled fibers as well as cost and environmental impact of the recycling methods under consideration, are accounted for. Quality is interpreted as the reusability potential of the recycled fibers; that is quantified through the equivalent volume fraction of recycled fibers that balances the mechanical properties of a composite composed of a certain volume fraction of virgin fibers. The proposed Index is offering an estimated balanced score, quantifying a trade-off between the reusability potential of the recycled fibers as well as the cost and the environmental impact of the recycling methods considered.

AbstractDe-manufacturing and re-manufacturing are fundamental technical solutions to efficiently recover value from post-use products. Disassembly in one of the most complex activities in de-manufacturing because i) the more manual it is the higher is its cost, ii) disassembly times are variable due to uncertainty of conditions of products reaching their EoL, and iii) because it is necessary to know which components to disassemble to balance the cost of disassembly. The paper proposes a methodology that finds ways of applications: it can be applied at the design stage to detect space for product design improvements, and it also represents a baseline from organizations approaching de-manufacturing for the first time. The methodology consists of four main steps, in which firstly targets components are identified, according to their environmental impact; secondly their disassembly sequence is qualitatively evaluated, and successively it is quantitatively determined via disassembly times, predicting also the status of the component at their End of Life. The aim of the methodology is reached at the fourth phase when alternative, eco-friendlier End of Life strategies are proposed, verified, and chosen.

Container terminals are the main hubs of the global supply chain but, conversely, they play an important role in energy consumption, environmental pollution and even climate change due to carbon emissions. Assessing the environmental impact of this type of port terminal and choosing appropriate mitigation measures is essential to pursue the goals related to a clean environment and ensuring a good quality of life of the inhabitants of port cities. In this paper the authors present a Terminal Decision Support Tool (TDST) for the development of a container terminal that considers both operation efficiency and environmental impacts. The TDST provides environmental impact mitigation measures based on different levels of evolution of the port’s container traffic. An application of the TDST is conducted on the Port of Augusta (Italy), a port that is planning infrastructural interventions in coming years in order to gain a new role as a reference point for container traffic in the Mediterranean.

Economic Considerations

The reuse of upgraded wastewater for beneficial uses is increasingly adopted and accepted as a tool in water management. However, funding of schemes is still a critical issue. The focus of this paper is on economic considerations of water reuse planning. A survey of pricing mechanisms for reclaimed water revealed that most schemes are subsidised to a great extent. In order to minimise these state contributions to the implementation and operation of reuse projects, their planning should identify a least cost design option. This also has to take into account the established pricing structure for conventional water resources and the possibility of gaining revenues from reclaimed water pricing. The paper presents a case study which takes into account these aspects. It evaluates different scheme designs with regard to their Net Present Value (NPV). It could be demonstrated that for the same charging level, quite different amounts of reclaimed water can be delivered while still producing an overall positive NPV. Moreover, the economic feasibility and competitiveness of a reuse scheme is highly determined by the cost structure of the conventional water market.

The Relationship

Transport is an important function in the supply chain. This chapter focuses on how to buy a transport service, how to form a transport contract, and how a transparent relationship will influence the risk and the relationship between transport provider and buyer. By developing a decision support tool (DST-model) and calculating the cost and the time parameters, the right price and the cost drivers will appear. The cases described in this chapter are a large Norwegian wholesaler for food, distribution to the retailer, and two Norwegian municipalities collecting household waste. In these cases, the buyer and the provider are acting blind in setting the transport price. This means that there is a huge risk for either a bankruptcy by the transport provider or an overpriced transport for the buyer.

Support Tool

Life Cycle Assessment (LCA) is a decision support tool that can be used to evaluate the potential environmental impact of a product system. Environmental impact associated with the production of (0.0508×0.1524×3.6576) m lumber referred to as “2by6” in the primary wood industry was evaluated. This assessment is a cradle to gate system with boundaries spanning from the point of raw material extraction in Osun state, to transportation of the lumber product to wood market in Ibadan, Oyo state. The study compared four production scenarios by varying haulage distance and energy source during production at two sawmill facilities located in Ife and Ikire in Osun state. Data obtained from the production system were analysed using GaBi6 software to estimate and classify the emissions into five impact categories. Life Cycle Impact Assessment result (LCIA) showed that Acidification Potential (AP), Global Warming Potential (GWP) and Smog Potential (SP) were the most significant impact indicators observed in the four production scenarios. AP (2.883, 3.352, 3.483, 3.951) kg H+ mole-Equiv, GWP (13.25, 14.44, 15.45, 16.65) kg CO2-Equiv and SP (1.86, 2.15, 2.24, 2.53) kg O3-Equiv. Scenario 4 which involved a longer transportation distance and employed a diesel generator for the milling process showed the least environmental performance. Processes that contributed significant impact were wood waste disposal method employed and the secondary transportation processes during logging activities. In order to achieve a better production system, practices that encourage less waste generation and the use of renewable energy were recommended.Keywords— LCA, lumber production, environmental impact, wood waste

Comparative Life Cycle Assessment

Owing to the cost of destination and transportation of ornamental stone processing waste, many studies focused on the reuse and recycling of this product. However, there is a scarcity of articles addressing the environmental viability of the recycling of ornamental stone. In this context, this study comprehends a comparative life cycle assessment of ornamental stone processing waste and conventional materials: sand, clay and limestone filler. The modelling software used was SimaPro 8.3.0.0 with Ecoinvent 3.2 database, employing the ReCiPe H/H methodology for impact assessment. The results show that the recycling of ornamental stone processing waste is environmentally preferable, and the artificial drying alternatives, such as flash dryer and rotary dryer, have lower environmental impact than extracting and processing clay through atomisation methods and limestone filler production. The sensitivity analysis indicated that it is possible to transport the ornamental stone processing waste 37 km after processing, so it reaches the same environmental impact as sand extracted by dredging. On the other hand, an increase of 25% in the energy consumption incremented only 7% of the environmental impact owing to the Brazilian energy mix.

Over the last 30 years, the milk processing process has shifted from the farm to the centralized cheese factory, which has had an impact on the management of transport logistics. In Morocco, several dairy units are located in rural areas with a poor road network, which means that milk collection has a significant impact on profit, affecting milk transport costs. The objective of this work is to develop a decision support tool based on internet of things technologies to optimize milk collection routes, reduce the cost of milk transport, and improve collection density. The tool developed in this study is based on a SIG system and farm milk volumes to estimate the cost per liter of milk for the regular route and to recalculate the same cost for the optimized collection route, combined with IoT technology to ensure the communication process between dairy farms, trucks, and dairy plants.
