Hazardous waste management should fulfil the following three main goals: (i) to protect human health and the environment, (ii) to reduce waste while conserving energy and natural resources and (iii) to reduce or eliminate the volume of waste to dispose of. The last two of these goals may derive from recycling, which aims at reducing raw materials and energy consumption and decreasing the volume...

Conceiving of nuclear energy as a social experiment gives rise to the question of what to do when the experiment is no longer responsible or desirable. To be able to appropriately respond to such a situation, the nuclear energy technology in question should be reversible, i.e. it must be possible to stop its further development and implementation in society, and it must be possible to undo its ...

The arrangements for bulk clinical waste handling were observed in 26 UK hospitals. Storage of waste carts in areas freely accessible to the public, and failure to lock individual carts was common. Many clinical waste carts and areas dedicated to their storage were in a poor state of repair. Substantial improvement is required in the management of clinical waste in hospitals in order: (1) to el...

This paper contains a model of waste elimination through design. It argues for the importance of managing design complexity in improving cost, quality, variety, and time{to{market performance variables. Management of design complexity is identi ̄ed with creation, choice, and application of design problem representations, divisions of design labor, and product architectures that provably eliminat...

The objectives of this study were to survey the different types of waste, their causes and suggestions to eliminate them according to the opinion of the nursing and medical staff from the Clinical Medicine, Surgery, Pediatrics, Rooming-In, and Nursery Units; and estimate the cost of the major source of waste found in the referred units. This descriptive, explorative study was performed at the U...

The plating industry is one of the main toxic chemicals consumers, which uses various chemicals, including solvents, acids, bases, cleansers, sophisticated organic ingredients, and metal salts of cadmium, nickel and chromium. Due to the growing production of industrial waste in spite of actions related to these wastes’ management, no comprehensive pattern was introduced at different levels. Thi...

The global economic recession has caused a reduced volume of orders, market saturation and low price competition pressure, so it is the right time for reorganization and optimization of companies and not for dismissal of employees. By dismissing employees the company loses good staff, employees accustomed to the work in their company, the moral of workers decreases and the reputation of the com...

The onset and development of Alzheimer’s disease (AD) is closely associated with the failure to eliminate waste from the brain [1]. The mechanisms behind this waste clearance remain largely unclear, however research suggests a strong link with the cerebral vasculature [2, 3]. Here we demonstrate computational evidence for a mechanism for cerebral waste clearance that is driven by functional hyp...
