In this study, two methods including data envelopment analysis (DEA) and life cycle assessment (LCA) were applied in order to determine energy efficiency and aid in the reduction of environmental burdens for tea production in Guilan province, Iran. The initial data were collected from 30 tea producers using a face‐to‐face questionnaire. Two models including constant return to scale (CCR) and variable return to scale (BCC) were used for calculating efficiency scores. Simultaneously, ten impact categories (AD, AC, EP, GW, OLD, FE, ME, HT, TE, and PO) were assessed to identify the main problem areas in the tea farms. The results indicated that the average technical efficiency, pure technical efficiency and scale efficiency were 0.881, 0.979, and 0.897, respectively. Moreover, the total energy saving was computed to be in the range of 7193 MJ ha−1. The highest share of total energy saving potential belonged to nitrogen with 65.93% observed. Based on the results, nitrogen, diesel fuel and machinery were the main hotspots in the majority of impact categories in both of present and DEA farms. Furthermore, in this study, the potential for impact category reduction was investigated and the results illustrated that between 17 and 20% of emissions can be reduced by converting present to DEA farms. In conclusion, the joint DEA + LCA method can improve the energy efficiency and environmental impacts in tea production, significantly. © 2017 American Institute of Chemical Engineers Environ Prog, 36: 1116–1122, 2017

“…Both species have lower toxicity potentials than found for other products, for instance, HTP for the production of 1 tonne of fish (live weight) has been reported between 639 and 3340 kg -1,4-DB eq, mostly related to food production (Ayer and Tyedmers, 2009). Similarly, HTP estimated from rice production has been reported between 327 and 1801 kg 1,4-DB eq (Khoshnevisan et al, 2014).…”

Highlights-The is the first study that presents the environmental impacts generated by the maintenance of domestics pets.-Life cycle analysis was used to assess the environmental footprint of domestic dogs and cats.-Carbon footprint from the maintenance of both pet types had its greater contribution by the production of food. AbstractMexico´s inhabitants have approximately 7 million dogs and cats as pets, of which there is no accurate information about their environmental impacts as a result of their feeding and comfort requirements. The objective of this study is to compare the environmental footprint between a dog and a cat in a family environment. For this purpose, a life cycle analysis was performed including, among other factors, its feeding and waste management in one year of life. Different environmental indicators including the carbon footprint were considered. It was found that the equivalent CO2 emission of a dog is twice that estimated for a domestic cat and that the main contribution is due to the food production. The ecological footprint that is generated when satisfying the requirements for pet´s well-being impacts in the environment contributes primarily to the carbon footprint.

Summary Stationary batteries are projected to play a role in the electricity system of Switzerland after 2030. By enabling the integration of surplus production from intermittent renewables, energy storage units displace electricity production from different sources and potentially create environmental benefits. Nevertheless, batteries can also cause substantial environmental impacts during their manufacturing process and through the extraction of raw materials. A prospective consequential life cycle assessment (LCA) of lithium metal polymer and lithium‐ion stationary batteries is undertaken to quantify potential environmental benefits and drawbacks. Projections are integrated into the LCA model: Energy scenarios are used to obtain marginal electricity supply mixes, and projections about the battery performances and the recycling process are sourced from the literature. The roles of key parameters and methodological choices in the results are systematically investigated. The results demonstrate that the displacement of marginal electricity sources determines the environmental implications of using batteries. In the reference scenario representing current policy, the displaced electricity mix is dominated by natural gas combined cycle units. In this scenario, the use of batteries generates environmental benefits in 12 of the 16 impact categories assessed. Nevertheless, there is a significant reduction in achievable environmental benefits when batteries are integrated into the power supply system in a low‐carbon scenario because the marginal electricity production, displaced using batteries, already has a reduced environmental impact. The direct impacts of batteries mainly originate from upstream manufacturing processes, which consume electricity and mining activities related to the extraction of materials such as copper and bauxite.
