Item type:Publication, Identifying environmental impacts linked to the production of plant-based spreads in Peru using life cycle assessment(Elsevier B.V., 2024-06-01)Plant-based spread products, such as margarine, are made up of a combination of diverse ingredients, many times arriving from different parts of the world. This makes their environmental impact challenging to compute. In Latin America, despite efforts in recent years to enlarge the number of food items that have been analyzed from an environmental perspective, many processed products remain unexplored. In this context, the main objective of the current study was to determine the environmental impacts of a set of five plant-based spread products in Peru using life cycle assessment. For this, primary data were collected from the main margarine producer up to the gate of the agroindustrial plant ready for distribution. Methodological choices, such as allocation, the computation of land use changes (LUCs) or agricultural management variability, were an important subset of variables to be considered in the life cycle modeling and accounted for through scenario and sensitivity analyses. Results demonstrated that greenhouse gas (GHG) emissions related to margarine production in Peru range from 1.66 to 6.00 kg CO2eq per kilogram of product, in a similar range to other studies in the literature. LUCs accounted for the highest contribution to GHG emissions, whereas crude oil extraction, as well as on field fertilizer emissions were the other main contributors. In other impact categories, plant protection agents were relevant in toxicity indicators, fertilization in eutrophication and transport in air quality-related categories. These results constitute a benchmark for the production of plant-based products in Latin America and are useful for attaining cleaner production, as well as for the optimization of ingredients and packaging design. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Evaluación de la contaminación acústica producida por la perforación de la piedra caliza en la cantera La Encantadora S.A.(2026-02-04)The investigation into noise pollution at the La Encantadora S.A. quarry aimed to evaluate the noise levels generated by limestone drilling and its impact on occupational and environmental health. A descriptive-correlational design was used, with on-site measurements at 29 points and surveys of 462 workers, complemented by statistical analyses (Student's t-test, Spearman's rank correlation coefficient, and Cronbach's alpha reliability coefficient).The results showed noise levels between 50.9 and 74.3 dB, exceeding the WHO's recommended limit (70 dB), although within national legal parameters (80–85 dB). The average was 60.22 dB, reflecting moderate exposure, but with critical areas along roads and in extraction zones. 85.1% of the workers perceived high levels of noise pollution, which correlated significantly with the intensity of the drilling, confirming risks of auditory fatigue, stress, and hearing loss.These findings highlight the urgent need to implement hearing conservation programs, acoustic barriers, continuous environmental monitoring, and preventative training. In short, noise management in non-metallic mining is not only a regulatory obligation but also an ethical commitment to health, human dignity, and environmental sustainability References [1] González, A., Pérez, B., & Rodríguez, S.
