As economy explodes and packaging industry flourishes, it is a critical issue that international community encounters the waste of resources and environmental pollution caused by packaging waste. As far as the Packaging Waste Management is concerned, European countries are abundant in worthwhile experiences, which could be used for reference to China's Construction of Packaging Waste Recycling System. Based on the analysis of industrial chain of European Packaging Waste Recycling System, this paper illuminates the corresponding policies, managements and role of distinguished interest-individual in different stages, which administers suggestions on how to put forward policies and implementing ordinance to China's Packaging Waste Management. 相似文献

本文以猪八戒网为研究对象,结合已往研究成果与猪八戒网调研结果,并将管理熵理论进一步应用于众包情境下,构建综合激励体系,从而测度激励体系协同激励效果。研究表明:目前猪八戒网接包绩效激励系统处于一定的有序状态,各激励指标的激励效果相对良好;二级体系内部指标协同效应较差,应注意"环境公平""品牌效应"与"信息转换机制"三项二级指标对激励系统稳定的干扰;"程序公平"和"交互公平"两项三级指标熵流值为正,对接包绩效产生显著抑制作用。通过测度激励系统的激励效果,有助于及时遏制正熵并提高激励负熵,进而实现总激励熵的下降,对激励盲点的发现与激励措施的动态维护具有重要意义。 相似文献

One third of food destined for human consumption is wasted globally, and much of the food waste that comes from high-income or developed countries is caused by poor marketing practices, consumer behavior, and consumption patterns. The present study focuses on developed countries to propose some marketing actions that could help in reducing food waste. A comprehensive analysis was carried out for each marketing variable, to provide a snapshot of actions and proposals that are being developed. Our study highlights the relevance of marketing in contributing to reduce food waste, through the removal of “Buy one, get one free” sales promotions, clarifying date labeling, or raising food waste awareness campaigns. The main contribution of this study is the proposal of marketing actions that help in tacking food waste. 相似文献

The knowledge of a product's life cycle is the first step on the search of sustainable development. The life cycle assessment (LCA) is an important method because it allows an environment accounting, where the extraction of natural resources and energy of the nature are considered and the "returns" to the same one and allows in evaluating relative potential the environment impacts generated. The present work had as objective to make an analysis of material and energy flows of the life cycle of three types of packaging for soft drinks: glass bottles of 390 mL, aluminum cans of 350 mL, and bottles of PET of 2,000 mL. The study considered processes since the extraction of raw materials for production of the packaging until the stages of recycling, after the consumption of the soft drink. For the research, an inventory analysis followed the LCA methodology. The main critical points of generation of negative environmental impact during the life cycle of each packaging had been the identified and quantified data in this study. The consumption of natural resources like water and other raw materials and energy, the generation of atmospheric emissions, solid wastes and wastewaters had been the analyzed categories. The results showed that, in accordance with the scenes and defined variables, the most important conclusion was that the bottle of glass presented a less favorable scene to the environment in comparison with other packaging. 相似文献

Consumers are increasingly bombarded with merchandise and offers, making clear the need for visually distinctive and sensorially engaging product packaging design. The current research demonstrates that the use of handwritten fonts on product packaging elicits an approach tendency and enhances haptic engagement, which influences product evaluation and choice likelihood. A pilot study quantifies the use of handwritten fonts in four grocery product categories to establish that the study of handwritten fonts as a packaging design element is a worthy one with managerial significance. Four experiments are then presented. Studies 1 and 2 use real products to show that a product label with a handwritten (vs. typewritten) font elicits haptic engagement and, enhanced product evaluations (Study 2). Study 3 identifies a boundary condition such that the focal effect is observed only for benign (safe and enjoyable) product categories, but not for risky (unsafe and dangerous) ones. Study 4 relies on a simulated store setup with actual products to illustrate the differential preference for products with a handwritten (vs. typewritten) font when choosing between brands in a benign (vs. risky) product category. 相似文献
