Multicycle reuse of disperse dyebaths on pilot scale jet equipment was investigated in dyeing of staple and filament 100% polyester knit fabrics. Long reuse runs of single shades produced good batch-to-batch shade uniformity. Multishade reuse runs were found feasible in the forward (light-mediumdark) direction for both fabric types even though dyes were not completely common in successive shade...

In a survey undertaken in the west of Scotland 801 adult diabetics taking insulin were questioned about their use of disposable or non-disposable needles and syringes, the life of such equipment, infected injection sites, and future preferences. Six hundred and eight preferred to use disposable equipment even if it meant reusing it; of the 413 who already bought disposable needles, 211 reused t...

There are currently no specific, published data quantifying the need for safe injection equipment or the amount of infectious sharps waste produced by testing and treatment programs for diseases such as HIV/AIDS, tuberculosis (TB), and malaria. With growing funding in these areas there is an increased need to ensure all programs are integrating safe injection approaches and equipment in order t...

In this paper we show how it is possible to reuse optical supports (CDs, DVDs, etc.) without using chemical or physical transformation, only employing a software that can easily run on domestic computers. This software can make obsolete optical supports useful again, converting de facto WEEE (Waste electric and electronic equipment) into EEE (Electric and electronic equipment). A massive use of...

The “concept for the reduction of SF6 emissions in magnesium foundries” from Solvay Fluor und Derivates is a possibility for magnesium foundries to be included in the SF6 ReUse Concept. It describes the efforts that have to be taken to switch to sulphur dioxide (SO2), but how to keep the door open for continuous operating with SF6. This four-step process allows the magnesium foundry to decide o...

In the last decade, the reuse of percutaneous transluminal coronary angioplasty (PTCA) equipment has been repeatedly discussed in the cardiological and infection control literature. Interest in this problem is growing since the frequency of PTCA procedures is increasing and cost containment in health care has been recognized as a necessity even in industrialized countries. Single-use devices in...

The waste associated with cleaning of process equipment is probably a significant contr ibutor to the total waste volume generated by industry. This paper addresses the following aspects related to equipment cleaning waste generation: o Review of reasons for cleaning process equipment o Reduction of cleaning frequency o Reduction of quantity and toxicity of cleaning waste o Costs associated wit...
