生化法应用在乙烯废碱液处理上的讨论

目前,国内乙烯装置产生的废碱液大多采用化学法中的湿式氧化法进行处理,主要存在投资高、氧化深度较低、运行成本高等问题,而采用生化法在这些方面优势明显。随着生化法在处理高浓度化工废水方面的成功,考虑其在乙烯废碱液处理上的应用,势在必行。本文主要参考苏州科环公司的全生物氧化技术在兰州石化公司的乙烯废碱处理中试实验,讨论其在乙烯废碱液处理上的可行性。

Local and organic food on wheels: exploring the use of local and organic food in the food truck industry

An exploratory study approach was used in this research to examine the use of local and organic food in Toronto’s food truck industry, the rationale for its use, and the challenges that food truck owners face in sourcing it. Results showed that all-but-one of the food trucks sourced local or organic food for their menu and were motivated by fresh taste/quality, social responsibility and customer preference. While there were challenges with utilizing organic/local food due to seasonality and cost, food trucks found they can derive benefits by way of increased patronage, menu differentiation, and competitiveness.     

The impact of different types of concernment on the consumption of organic food

Previous research has mainly focused on consumers' environmental values and attitudes to explain green consumption. However, it has been neglected how situational factors like the way a consumer is affected by the impacts of environmental pollution influence environmental attitudes and the demand for organic food products. To fill this void, we firstly introduce a taxonomy of different types of factual concernment and perceived concern. Factual concernment describes the manner in which a person is affected by the negative consequences of environmental pollution, whereas perceived concern expresses an anxious sense of interest. Building on that taxonomy, an experimental study analyses how four types of factual concernment (direct vs. indirect; material vs. immaterial) influence consumers' perceived concerns (in terms of environmental and health concern) as well as the readiness to gather information, the readiness to make sacrifices, the willingness to pay higher prices and purchase intentions. The study reveals that particularly direct concernment fosters the consumption of organic food. However, the study did not find any differences between the influences of material and immaterial concernment on the organic food purchase decision.     

A review of the ‘consumer interest’ in organic meat

The study aims to provide a critical review of the literature on the consumer interest in the UK in organic food, with a particular focus on organic meat. Given that people are more likely to purchase products if they have faith in them, the regulation of organic food standards is reviewed to explore issues affecting consumers. This is followed by a review of the organic meat sector. Aspects of the consumer interest considered in this paper include consumer information, consumer access, consumer safety, consumer choice and consumer representation. As the literature on organic food/meat in the UK is extensive, it was therefore necessary to be selective with regard to the publications suitable for this review. Most of the literature selected for this paper has been drawn from UK publications, although several European and international sources have also been used. The review found that there is a considerable level of interest in the UK organic meat sector. As the regulation of organic food produced is set at varying standards across the European Union, this could lead to consumers being misled regarding the quality of products offered. It was also found that, although consumers perceive organic foods as healthier, more nutritious and tasting better than non‐organic products, the literature shows that this may have only a limited basis on fact. Contamination of organic products with pesticides and even genetically modified ingredients is always possible. Organic farmers are permitted to use other ingredients in organic meat products that may be harmful to health. Escherichia coli and Salmonella risks associated with conventional meat also appear to affect organic meat. Consumers need clear, accurate and reliable information about organic meat. They also need to be provided with safe products, a choice of organic products, access to organic products and to be represented effectively.     

Effect of knowledge on decision making in the context of organic cotton clothing

This research was designed to study whether consumer knowledge on organic cotton and relevant issues influences attitude toward and price acceptance of organic cotton clothing. The effect of consumer knowledge was also studied on the way consumers use product label information in purchasing organic cotton clothing. An online survey was developed to measure the variables including experimental choice‐based conjoint models for mandatory and auxiliary label specifications. Four hundred ninety‐eight people completed the survey. The results indicated that moderately and highly knowledgeable participants were more willing to buy organic cotton clothing at higher price points and they had more positive attitudes toward organic cotton clothing than low knowledgeable participants. The results suggest that differentially knowledgeable consumers may attend to different types of information provided on product labels to evaluate organic cotton apparel products. Providing product‐related information on product labels is essential; however, providing additional information on the benefits of using organic cotton and socially responsible business practices may improve consumers’ knowledge and acceptability of organic cotton apparel products.

Explanatory factors for efficiency in the use of social networking sites—The case of organic food products

In some markets, organic foods face problems such as consumer misinformation and confusion, high prices compared to conventional equivalents, or few points of sale. The answers to these problems include information and communication technologies, particularly social networking sites (SNS), given their potential for conveying information and connecting customers and suppliers at less cost. It would be useful to ascertain the psychology of social media use and which factors determine SNS efficiency among organic producers. This study of the efficiency of SNS use in two strategic sectors for Spain—olive oil and wine—used data envelopment analysis and, in a second stage, qualitative comparative analysis (QCA) to detect the contextual variables that explain the highest efficiency indices. The results showed that the more market‐oriented sector (wine) has a higher average efficiency of SNS use and pointed to the following explanatory factors: SNSs mentioned on corporate websites, number of employees, the manager's educational background, and length of SNS use.
