Understanding Current Challenges in Evaluating Environmental Impacts for Aggregate Producers through a Case Study in Western Sweden

Abstract

To improve environmental performance of a product or activity, an understanding of the environmental impacts associated with it is needed. Quantification of environmental impacts can be achieved through the standardized measurement-based tool of Life Cycle Assessment (LCA). However, challenges occur when trying to apply a standardized tool to a nonstandardized industry such as the aggregate industry. This study aims to provide greater understanding of the challenges facing the aggregate industry, particularly producers, in applying LCA. This was conducted through a literature review, to establish the current understanding of challenges, accompanied by a case study where a site-specific LCA was conducted with a large enterprise at a crushed-rock-production facility in western Sweden, to gain new industry-specific insight. A total of 13 challenges were identified: seven methodological and six systemic. Out of these 13 challenges, 3 were deemed a high risk to the implementation of LCA by aggregate producers, and 3 to the integrity of results. A best-practice framework is suggested to incorporate LCA into current environmental management techniques utilized at quarry sites in Sweden to overcome some challenges. However, LCA used for environmental management should not lead to double work if LCA is being utilized for Environmental Product Declarations, and further research is encouraged to find appropriate solutions with the most efficient allocation of the resources needed in conducting LCA studies.

A review of data analytics techniques in enhancing environmental risk assessments in the U.S. Geology Sector

“…These challenges include the difficulty in standardizing a tool for a nonstandardized industry, the complexity of conducting site-specific LCAs, and the risk of double work when LCA is used for Environmental Product Declarations. The research highlights the need for a best-practice framework to incorporate LCA into current environmental management techniques, while also acknowledging the necessity for further research to efficiently allocate resources in conducting LCA studies (Lee et al, 2022).…”

Minería y Medio Ambiente: Un Análisis de la Declaración de Impacto Ambiental en Proyectos de Explotación Minera La Damira

“…Para una primera aproximación se han desarrollado matrices para cada una de las etapas del proyecto estas matrices se denominan identificación de impactos (Corzo et al, 2015). Vistos individualmente, los principales impactos negativos serán los que resulten de algunos trabajos en interior mina, del emplazamiento de las canchas de almacenamiento y de la construcción de caminos de acceso, debido a la baja reversibilidad de sus efectos sobre el paisaje y el ambiente físico (Lee et al, 2022). No obstante, pág.…”

“…Sin embargo, este desarrollo económico a menudo viene acompañado de impactos ambientales significativos (Campero et al, 2021). En el contexto peruano, un país rico en recursos naturales, la explotación minera ha sido un motor clave para el crecimiento económico, pero también ha planteado desafíos importantes en términos de conservación del medio ambiente y sostenibilidad a largo plazo (Lee et al, 2022).…”
