The economics of tire remanufacturing

The world market for tires is described to identify the current material flow from raw materials to tires and the used tire disposal problem. Then, I describe the value-adding operations in the tire production process and in the tire retreading process. Once retreading is identified as the only recovery alternative that maximizes tire utilization, I explain why heat generation is the only recovery alternative, when retreading is not technically feasible. The economic values of heat generation in electric plants and in cement kilns are discussed. The paper culminates with the case of retreading, the tire remanufacturing process and the recommendation of a simple decision rule for selecting the number of times a tire should be retreaded to maximize its utilization.     

Incidents in manual handling activities

More than 20000 handling manoeuvres in loading or unloading trailers in a large transportation company were observed. The aim of the study was to determine the frequency and nature of the incidents occurring whilst handling. The incidents were recorded and interpreted from a double perspective, namely as risk factors and as activity regulation factors. The study showed that on average, one incident occurred in every seven handling manoeuvres: 71% of them were related to the environment, and 29% to the activity. While numerous, the environment-related incidents were generally without consequences. In this respect, the activity incidents appeared more risky; also, the majority of these incidents occurred during the load positioning phase. The study also showed that loads are re-handled twice as often in unloading as in loading, the frequency of re-handlings varying widely from one handler to another. The reasons why so few of the observed incidents are reported in accident studies and their significance in the understanding of handling problems are discussed.

新型生物转筒处理食品生产废水的试验研究

生物转盘（筒）是处理中、小流量废水的一种较经济有效的方法，本试验采用新型填料式生物转筒作为关键设备处理食品加工废水，结果表明：系统对COD、BOD5、SS和LAS有显著的去除效果，当进水COD为1200～1700mg/L，BOD5为600～1200mg/L时，出水水质可以达到广东省地方标准《水污染物排放限值》（DB44／26-2001）中的二级标准。     

我国石油工业环境保护相关法律问题

目前,我国对石油工业领域环境保护立法,采取的是特殊行业规制与一般规制相结合的模式。总体上看,我国石油工业环境保护领域已建立起初步的法制框架,但仍须进一步完善立法、执法、制订应急预案和建立信息公开机制等。
