对废旧塑料回收利用的思考

随着塑料工业的高速发展，塑料制品在给人们的工作和生活带来舒适与便利的同时，废弃塑料数量不断增加，引发的环境问题也日益突出，如回收水平不高、环境污染、存在卫生安全隐患等。本文介绍了我国废旧塑料巨大的回收空间和良好的经济效益，总结了塑料回收利用新思路，最后提出为了保障行业的健康发展，应早日建立健全法律机制。     

循环经济变废为宝多种方式可供选择

随着塑料制品消费量的与日俱增，废弃塑料也日益增多。据报道，我国每年产生1100万吨废旧塑料，若存放、运输、加工应用及后处理不当，势必严重损害环境。     

国外塑料食品包装材料回收利用的现状和发展动态

塑料以其比重小、易于加工及优良的气密性能等特点与金属、纸张和玻璃等一样 ,在国计民生的各个领域中成为最基本的应用材料之一。特别是在食品包装方面 ,它以薄膜、板材或瓶罐等多种形态被广泛应用。尤其是近年来 ,由于采用了与铝箔等材料进行复合加工的方法而使之具有高气密性等性能 ,因而在蒸馏食品的开发及延长食品保存期等方面占据了极重要的位置。但是 ,近年来由于保护地球环境的呼声日益提高 ,废弃物和垃圾的处理问题也日趋严重 ,因而迫使人们不得不彻底改变“大量生产 ,大量消费”的观念 ,转而注重尽可能充分利用地球有限的资源 ,维…     

五类食品包装机械市场潜力巨大

近年来,随着食品包装市场不断扩大,对食品包装机械亦提出了更新、更高的要求。据预测,近期内我国食品包装机械将有以下项目亟待开发:粮食及食用油深加工包装设备。目前,粮油食品的各种小型包装近年来异军突起,市场消费量直线上升。针对当前的发展趋势,开发粮油多种计量方式的中

塑料包装废弃物的回收处理途径

塑料包装废弃物严重污染环境，对其进行回收处理应尽量减少污染。塑料包装废弃物的回收处理途径主要包括填埋，能量回收型焚烧，再生处理，降解和其它回收途径，本文对这些回收处理途径进行了探讨，并分析了各自的优缺点。     

关于再生塑料用于包装袋的探讨

近年来，由于石油价格的上涨，国内用于塑料包装袋的主要原材料——低密度聚乙烯和高密度聚乙烯等大幅上涨，已超过了历史上的最高价格。原材料涨价使得生产成本提高，给使用新原料生产塑料包装袋的厂家带来了压力。而对再生塑料回收利用，并以此为主要原料生产塑料包装袋的企业却带来了商机。一些商贩，以及个别饭店、酒店在知情或不知情的情况下，开始大量使用以再生料生产的塑料包装袋，甚至直接包装食物，危害了人们的身体健康。因此，本文仅对再生料的一些来源、生产包装袋的过程和鉴别方法进行探讨，供大家参考。     

Mushrooms from waste

In view of the current energy and food crisis and continued population growth, there is an urgent need for more advanced research in food production. Only through constant and creative research can a substantial breakthrough in the technology of food production be achieved, and a larger quantity and higher quality of food be provided. One research project which should be seriously considered is how the wastes from agriculture and industry can be used for producing food protein through the cultivation of mushrooms.     

How to get great research cited

Academic success traditionally has been assessed by publications in highly ranked journals. Other measures of research quality such as citations are now available, and these measures offer a wider perspective of academic contribution beyond simple article counting. Citations now are an important consideration when evaluating research impact and quality. Google Scholar, Scopus, and other programs are readily available to provide citation counts; and other measures such as Hirsch's h-index have also been developed. In this editorial, we discuss the issue of research citation, focusing on strategies that can be used to ensure that one's research output is read by the intended academic and practitioner audiences. We first examine why articles get cited including a consideration of types of articles and types of citations. We then outline how to set up and present research. This includes a discussion of the research's strong contributions to the field; conceptual and theoretical development; compelling findings; and clear conclusions and implications. Third, we provide guidelines to create visibility and understanding of the article's contribution in the offline research community and beyond. Fourth, we examine the critical role of the online environment in creating visibility for an article. Here, after having given an overview of academic search, we discuss keywords; design and structure; graphics; metadata and university research repositories; and interactive social media content. We conclude by cautioning about unethical practices to increase citations.
