The Landes de Gascogne forest, located in southwestern France, spans nearly 10,000 km2 and consists largely of maritime pine (Pinus pinaster). This forest in unique to Europe because it is almost entirely created and managed by man for specific industries. On the basis of a material flow analysis, we assessed the upstream supply chain of maritime pine from 2013 to 2019, using a cradle-to-gate approach. The assessment is based on data provided by Alliance Forêts Bois, an important stakeholder of the region and leader in the production of forest resources in France. For various reasons, the harvest totals decreased 10% in the last years. We identified a clear orientation to specific industries—in 2019, 45% was used as pulpwood. This is due to the overall design of the current territory, species of tree, and market values of the pulp and paper industry. The current design provides a limited supply of old growth trees, which produce high-quality logs for construction-based products, and are also more resistant to climate variability. A future shift or balance in raw material flows could be a crucial step in protecting the long-term economic viability of the region. This article aims to contribute to new attempts in providing comprehensive views of stocks and flows in the French forest-wood supply chain.

AbstractClimate change will increase the frequency and severity of supply chain disruptions and large-scale economic crises, also prompting environmentally protective local policies. Here we use econometric time series analysis, inventory-driven price formation, dynamic material flow analysis, and life cycle assessment to model each copper supply chain actor’s response to China’s solid waste import ban and the COVID-19 pandemic. We demonstrate that the economic changes associated with China’s solid waste import ban increase primary refining within China, offsetting the environmental benefits of decreased copper scrap refining and generating a cumulative increase in CO2-equivalent emissions of up to 13 Mt by 2040. Increasing China’s refined copper imports reverses this trend, decreasing CO2e emissions in China (up to 180 Mt by 2040) and globally (up to 20 Mt). We test sensitivity to supply chain disruptions using GDP, mining, and refining shocks associated with the COVID-19 pandemic, showing the results translate onto disruption effects.

An Environmental Protection Agency-funded project was the material flow analysis of naphthalene-containing products in an effort to eliminate, reduce, or replace the sources of naphthalene. The project analysis began with manufacturers who use naphthalene-containing products in their processes. It identifies the basic characteristics of naphthalene as a common polynuclear aromatic hydrocarbon, which is released to the environment. Included are likely sources of naphthalene emissions and releases as they were identified for further investigation. This paper, which is the sequel to IMECE 2005-82808, highlights a secondary objective of the project: to document the approach used in identifying the naphthalene flow from the raw material to its various products. This secondary objective was to show how process, product, and quantity data can best be gathered. Within the project, there were several means to collect data, some that have worked better than others. The purpose of this objective was to provide the framework of a proven approach to generating the material flow so that it can be followed for other priority chemicals that populate the EPA list.

An Environmental Protection Agency-funded project centers on the material flow analysis of naphthalene-containing products in an effort to eliminate, reduce, or replace the sources of naphthalene. The analysis commences with manufacturers who use naphthalene-containing products in their processes. Also, the analysis works in reverse by starting with the naphthalene user, as the material will be traced to the source in an effort to identify elimination/reduction opportunities throughout the material’s life cycle. A particular focus is the potential for removal of naphthalene from the primary processor’s raw material. A completed material flow accounting of naphthalene in the United States is the product of this work. The paper highlights the preliminary part of the study. It identifies the basic characteristics of naphthalene as one of the largest polynuclear aromatic hydrocarbons that is released to the environment. Included are likely sources of naphthalene emissions and releases as they are identified for further investigation.

The unprecedented technological development and economic growth over the past two decades has resulted in streams of rapidly growing electronic waste (e-waste) around the world. As the potential source of secondary raw materials including precious and critical materials, e-waste has recently gained significant attention across the board, ranging from governments and industry, to academia and civil society organizations. This paper aims to provide a comprehensive review of the last decade of e-waste literature followed by an in-depth analysis of the application of material flow analysis (MFA) and life cycle assessment (LCA), i.e., two less commonly used strategic tools to guide the relevant stakeholders in efficient management of e-waste. Through a keyword search on two main online search databases, Scopus and Web of Science, 1835 peer-reviewed publications were selected and subjected to a bibliographic network analysis to identify and visualize major research themes across the selected literature. The selected 1835 studies were classified into ten different categories based on research area, such as environmental and human health impacts, recycling and recovery technologies, associated social aspects, etc. With this selected literature in mind, the review process revealed the two least explored research areas over the past decade: MFA and LCA with 33 and 31 studies, respectively. A further in-depth analysis was conducted for these two areas regarding their application to various systems with numerous scopes and different stages of e-waste life cycle. The study provides a detailed discussion regarding their applicability, and highlights challenges and opportunities for further research.
