BACKGROUND Rice–duck coculture is an ecological agricultural mode; however, the nutritional and environmental benefits of transforming from conventional rice monoculture to rice–duck coculture are unknown. Based on survey data and the life‐cycle assessment approach, this study conducted a carbon footprint evaluation of conventional rice monoculture (CR), organic rice monoculture (OR), and organic rice–duck coculture (ORD) using different functional units. RESULTS The carbon footprint per hectare of ORD (7842 ± 284 kg CO2eq ha−1) was slightly lower than that of CR (7905 ± 412 kg CO2eq ha−1), while higher than that of OR (7786 ± 235 kg CO2eq ha−1). Although the rice yield of ORD was slightly lower than that of CR, its nutrient density unit (NDU) did not decrease significantly due to the additional duck yield. Thus, the carbon footprint per NDU of ORD was significantly lower than that of OR by 24.3% (P < 0.05) and was 5.8% higher than that of CR, but this was not statistically significant. Due to the higher economic profits of ORD, its unit of carbon footprint per economic profit was significantly reduced (by 47.1–75.7%) compared with the other two farming modes, while the net ecosystem economic budget was significantly increased by 98.5–341.9% (P < 0.05). CONCLUSION Transforming from a rice monoculture to a coculture system will contribute to a win–win situation for human health and environmental sustainability. This study highlighted the abundant nutritional output function of the rice–duck coculture and analyzed the urgency and necessity of transitioning from traditional agriculture to ecological agriculture from the production and consumption perspectives. © 2022 Society of Chemical Industry.

China has pledged to become carbon neutral by 2060 and has employed a variety of strategies to minimize carbon emissions. As people’s support to achieve the carbon neutrality goal affects its success, this study reviewed the public’s perception of carbon neutrality via cluster analysis on microposts. The co-occurrence matrix showed 258 nodes and 3,212 ties in the carbon neutrality social network. The top five most prominent nodes were neutralized, energy, China, blue-green, and economy. The keyword like blue-green (means water and plant) illustrated the popular terminology used by mainland Weibo users and its essential role in carbon neutrality. The multidimensional scaling analysis found that there were 11 clusters in carbon neutrality. The results revealed that people’s concerns about carbon neutrality were mainly related to the environment (e.g. low carbon, sustainable, and wind power), social (e.g. country and poverty), and governance (responsibility, government report). Weibo users believed that achieving carbon-neutrality allows us to pursue a better life. Among the data collected, positive sentiment microposts (83.9%) were approximately eight times more than the negative ones (9.9%), and only 6.3% were neutral. The results indicated that most Weibo users were opitimistic on carbon neutrality.

Carbon Footprint Reduction During the Wire Drawing Process at an Electrical Cable Manufacturing Company

Proceedings of the International Conference on Industrial Engineering and Operations Management

This study proposes improvements in one of the processes of the operational flow of an electric cable manufacturing company with the objective of reducing the environmental impact of its emissions. The improvement focuses on the copper annealing sub-process, in relation to the wire drawing operation. Under an experimental design, a diagnosis was made of the 2.5 mm diameter wire production process. It was found that it generated unnecessary waste of electrical energy in the annealing stage. With the help of a group of experts, the carbon footprint indicator was also calculated. The solution implemented consisted of the partial elimination of the primary drawing annealing operation and recurring adjustments for the efficient operation of the rest of the process. The benefit of the proposal, validated through laboratory tests, was calculated at USD 2.81 per year for each dollar invested. The results show that the wires only changed in their mechanical properties, having mainly an elongation of 35%-36% for the soft wire and 2% for the hard wire. However, the change in these mechanical properties does not chemically affect the quality of the final product thanks to the adjustments made, reducing the carbon footprint by 1444,186 tCO2 per year. This proposal could be replicated in similar companies in the metallurgical sector.
