“…However, as stated in the NDC, the environmental impact of the use of proper fertilizers has not been explored in this sector. It is well known that the application of different fertilizers is strongly correlated with environmental impacts (Mohammadi-Kashka et al, 2023;Quirós et al, 2015). Therefore, it is important to study the effect of fertilization on the LCA of non-centrifugal sugar production.…”

Non-centrifugal sugar (Panela) is a natural sweet enhancer obtained from sugarcane. In this process, waste from the agricultural industry is disposed of incorrectly, fossil fuels are used, and the furnaces' efficiency is low, leading to environmental problems. Therefore, this study aims to assess the environmental impacts of Panela production to identify possible hotspots and propose alternatives to reduce the environmental impacts such as acidification, global warming, freshwater eutrophication, and particulate matter emissions. Aspen Plus, interviews, and databases were used to determine life cycle inventory that then was used to calculate environmental impacts. Central results showed that producing 1 kg of Panela results in a carbon footprint of 4.09 kg CO2-eq and removes 6.02 kg CO2 during the growth phase. Moreover, the acidification potential, freshwater eutrophication, and particulate matter emissions were 0.21 molc H+-eq, 0.0077 kg P-eq, and 0.0042 kg PM2.5-eq, respectively. These impacts are mainly due to the harvesting phase, as agro-industrial wastes such as sugarcane press mud, and leaves are disposed of incorrectly. To solve this issue, suitable methods of fertilization are proposed, achieving a reduction in acidification potential and particulate matter emissions by 80%. In addition, greenhouse gas emissions are reduced by 35% if bagasse is not burned. Hence, the combination of both alternatives will improve the sustainable production of Panela. The significance of this study is to show new alternatives to reduce the environmental impact of Panela. Besides, these strategies such as improving agricultural practices and designing new furnaces are aligned with national policies.

Global warming has driven the expansion of cultivated land to high-altitude areas. Intensive vegetable production, which is generally considered to be a high economic value and high environmental risk system, has expanded greatly in high-altitude mountainous areas of China. However, the environmental cost of vegetable production in these areas is poorly understood. In this study, pepper production at low (traditional pepper production area) and high (newly expanded area) altitudes were investigated in Shizhu, a typical pepper crop area. The output and environmental cost at the two altitudes were identified. the influence of resource inputs, climate, and soil properties on pepper production was evaluated. There were obvious differences in output and environmental cost between the two altitudes. High-altitude pepper production achieved a 16.2% lower yield, and had a higher fertilizer input, resulting in a 22.3% lower net ecosystem economic benefit (NEEB), 23.0% higher nitrogen (N) footprint and 24.0% higher carbon (C) footprint compared to low-altitude farming. There is potential for environmental mitigation with both high- and low-altitude pepper production; Compared to average farmers, high-yield farmers groups reduced their N and C footprints by 16.9–24.8% and 18.3–25.2%, respectively, with 30.6–34.1% higher yield. A large increase in yield could also be achieved by increasing the top-dress fertilizer rate and decreasing the plant density. Importantly, high-altitude pepper production was achieved despite less advanced technology and inferior conditions (e.g., a poor road system and uneven fields). It provides a reference for the study of the environmental cost of other high-altitude regions or other crop systems at high-altitude areas.
