An Econometric Analysis of Global Waste Paper Recovery and Utilization

The main purpose of this paper is to provide aneconometric analysis of the most importantdeterminants of inter-country differences inwaste paper recovery and utilization rates. Byemploying pooled time series and cross-sectiondata over 49 countries worldwide and sevenyears, the paper concludes that relative wastepaper recovery and use depend largely onlong-standing economic factors such aspopulation intensity and competitiveness in theworld market for paper and board products. Wealso find evidence that supports the conjecturethat rich countries tend to recover relativelymore waste paper than is the case in low-incomecountries, reflecting the higher demand forwaste management and environmental policies inmore developed economies. As recovery andutilization rates are determined by economicand demographic characteristics the degree ofpolicy flexibility in affecting these rates maybe limited. In particular, an ambitiousutilization rate target may be very costly toenforce as it can conflict with existing tradepatterns of paper and board products as well aswith other environmental goals. Additionalpolicy targets may therefore be desirable,especially since paper recycling is motivatedprimarily by environmental concerns and seldomis a benign activity in itself.     

Recycling of plastics: A materials balance optimisation model

At present the volume of solid waste produced in modern consumer societies is increasing, requiring policy measures to reduce the volume of waste to be dumped or incinerated. In this article a materials balance optimisation model for the recycling of plastics is developed to analyse the impact of policy measures that stimulate recycling. The study presents the structure of the optimisation model and it gives the results of a charge imposed on the dumping and incineration of plastics. The calculations show that considerable effort should be made to reach the recycling targets for plastic that have been set by the public authorities for the year 2000.     

农业废弃物资源化路径及综合效益分析——基于鄂、豫两省调研数据

运用模糊综合评价方法对农业废弃物资源化不同路径的经济、社会和生态效益进行评价、对比分析,以此探求农业废弃物资源化不同路径的比较优势,优化农业废弃物资源化利用结构.评价结果显示:农业废弃物资源化不同路径的生态效益优劣排序为:饲料化＞能源化＞基质化＞肥料化＞材料化;经济效益的优劣排序为:肥料化＞基质化＞能源化＞饲料化＞材料化;社会效益的优劣顺序为:基质化＞材料化＞能源化＞肥料化＞饲料化.在农业废弃物资源化不同路径的生态、经济和社会效益评价的基础上,得出农业废弃物资源化不同路径的综合效益优劣顺序为:基质化＞能源化＞肥料化＞饲料化＞材料化.据此,提出了优化湖北省农业废弃物资源化利用结构的建议.     

How scolding can encourage consumer engagement with plastic waste issue? The moderating role of consumers’ mindset

Extant literature has reported mixed findings on the effectiveness of praising versus scolding in social marketing messages, such as how to encourage consumer engagement with plastic waste issue. Against this backdrop, this research investigates the moderating role of consumers' mindset in this regard. This research reports two experimental studies and demonstrates that consumers with a growth (vs. fixed) mindset will experience higher levels of outcome efficacy when evaluating a scolding (vs. praising) message. In addition, this research employs different methods of eliciting consumers' mindset and examines different dependent variables (product choice in Study 1 and donation allocations in Study 2). The results of this research thus offer a fresh theoretical perspective on the effectiveness of scolding (vs. praising) in enhancing consumer engagement with plastic waste issue by examining the moderating role of consumers’ mindset and establishing the underlying mechanism.
