“…Valko and Kudenko (2024) and Paul et al (2024) critically evaluate the reliability of models estimating the energy and environmental footprint of digital currencies, which, although not directly related to traditional mining, provide insights into the challenges of assessing the environmental impact of geographically distributed networks. The challenges associated with assessing the environmental impact of the mining industry are similar to those faced when evaluating the environmental footprint of other industries, as evidenced by research conducted in the fruit sector (Lu et al 2024;Manakas et al 2024;Waqas et al 2024). Although not directly related to the mining industry, the ndings of these studies provide useful insights into the di culties of standardizing and harmonizing environmental accounting methods across different industries.…”

The extractive industry has a profound impact on the environment, emphasizing the need for environmentally friendly practices. This study employs a mixed-methods approach to evaluate the environmental impact of bauxite and iron mining projects in Boke and Kerouane, Guinea. Primary data were collected from October 2022 to January 2023, with a focus on water pollution, soil, noise, air quality, vegetation, fauna, and flora. A reference matrix was used to assess the impact of mining activities, categorizing them as negligible, moderate, or significant. This study analyzed 400 soil samples from 21 sites to evaluate water quality, measured noise levels using an NL52 Class 1 sound level meter, and monitored air quality using the DustMate system. Biodiversity surveys were conducted to identify potential impacts on the receptors. The results showed that the pH of the water averaged between 5.79 and 8.66, and some companies exceeded the average value of electrical conductivity. The soil composition showed the presence of Cr, Cu, Ni, and Zn in both the mining regions. Noise and particulate matter pollution exceeded the guideline values at some sites. This project will result in the direct loss of natural and modified habitats, including erosion of lateritic soil in ridge areas. Non-native plant species have been identified in the Kerouane Iron Project. This study underscores the need for policymakers to integrate climate change mitigation strategies into land use planning and use an integrated index of economic and environmental performance to improve sustainability in the mining industry.

The global flows of cultivated seaweed were estimated for the year 2019 using a combination of literature review, assumptions, and simple conservation of mass calculations. Red seaweeds were found to be the largest contributors to the hydrocolloids industry, for both food and non‐food applications. Carrageenan‐containing species were found to be the largest contributors to both food (62%) and non‐food (55%) hydrocolloids and are the primary source for water gels, which make up 27% of non‐food hydrocolloids, followed by pet food (16%), toothpaste (6%), and others (6%). Carrageenan also accounts for almost all meat products, which make up 35% of the food hydrocolloid industry, and dairy products, which make up 26%. Agar‐containing seaweeds are used in confections (10% of food hydrocolloids), baking (9%), and other (2%) and make up 15% of non‐food hydrocolloids. Porphyra (nori) is cultivated for direct consumption and makes up 23% of direct food consumption. Cultivated brown seaweeds were found to comprise Laminaria/Saccharina for alginate production (30%), Laminaria/Saccharina for direct consumption (44%), and Undaria for direct consumption (16%). About half of the alginates produced make up 18% of food hydrocolloids, and the other half is used in non‐food hydrocolloids comprising technical grades (28% of non‐food) and animal feed (3%). The results are discussed in the context of emerging markets for seaweed and the potential for seaweeds as a substitute for staple foods, and the environmental impact of seaweed farming is explored through a review of life cycle assessment studies.
