Abstract The agricultural sector in the world is facing social expectations to reduce energy consumption and environmental impacts; and at the same producing enough food and fiber for the growing world population. The purpose of the present research to determine the economic, energy consumption, and environmental indicators in coriander seed production using novel approach of material flow cost accounting (MFCA) along with classical life cycle assessment (LCA). The positive output and negative energy were 25485 and 6742 MJ ha−1, respectively. Energy efficiency, net energy gain, specific energy, and energy productivity indicators were calculated as 0.6, -11944 MJ ha−1, 17.4 MJ kg−1, and 0.06 kg MJ−1, respectively. The average production cost was calculated as 588 $ ha−1 (334 $ ton−1) whereas gross income was 1267 $ ha−1 (720 $ ton−1). The value of negative products in coriander production was estimated as 239 $ ha−1 (136 $ ton−1). Seed shedding at harvest and water loss due to inefficient irrigation system were found to be the major negative products (economic and energy) in the system that can enhance the system productivity upon improvement. The values of benefit costs ratio and economic productivity were 1.74 and 3 kg $−1, respectively. The acidification potential (58.2 kg SO2 eq ton−1), global warming potential (510 kg CO2 eq ton−1), photochemical oxidation potential (0.13 kg C2H4 eq ton−1), and eutrophication potential (23 kg PO4 −3 eq ton−1) indicators were evaluated. The hotspots in point of economic (labor and seed shedding), energy use (nitrogen fertilizer and machinery) and energy loss (seed shedding), and environment (diesel fuel consumption) were determined which can be used to optimize coriander production through decreasing the material and energy consumption in the field. The results showed that MFCA combined with LCA is a powerful tool in identifying hotspots in crop production systems and can be used in developing more sustainable systems as well as in developing sustainability models.

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.
