There are a wide range of modern waste disposal systems and the costs of operating them greatly vary. The type of waste disposal system to be used is selected based on the nature of the operation, process and needs of the local community. In Iran, mixed municipal waste with significant contamination and humidity is prevalent. As a result, the most commonly used methods implemented in European a...

The volume of e-waste is growing around the world, and, increasingly, it is being disposed of by export from developed to developing countries. This is the situation in Ghana, and, in this paper we address the potential consequences of such e-waste disposal. Herein, we describe how e-waste is processed in Ghana, and what the fate is of e-waste-chemical contaminants during recycling and storage....

The paper summarises the main results gathered from two extensive applications of Life Cycle Assessment (LCA) to the integrated municipal solid waste management systems of Torino and Cuneo Districts in northern Italy. Scenarios with substantial differences in terms of amount of waste, percentage of SC and strategies for the disposal of residual waste are used in order to discuss on strategies t...

Sheep meat presents variations in qualitative characteristics that influence consumer preference. These are influenced by ante-mortem factors, such as sex, breed, age at slaughter and feeding; post-mortem cooling storage time temperature. Twenty-four uncastrated Suffolk lambs were housed individual corrals received one of four treatments consisting levels replacement sorghum silage with wet bre...

Thermococcus may be an important alternative source of H2 in the hot subseafloor in otherwise low H2 environments such as some hydrothermal vents and oil reservoirs. It may also be useful in industry for rapid agricultural waste treatment and concomitant H2 production. Thermococcus paralvinellae grown at 82°C without sulfur produced up to 5 mmol of H2 L(-1) at rates of 5-36 fmol H2 cell(-1) h(-...

Fermentation is an important, if not the most important process step in the production of beer. It is subject to alterations stemming from the variation in the yeast, a living organism, and due to the complex raw materials of biological origin. The variability may manifest in changes in the fermentation speed or cause off-flavors in beer. Thus, there is a need for tools, both analytical and com...

This study concentrates on designing a medical waste management system with a hierarchical structure, including a local government and a waste management planner. The upper-level seeks to design and control the waste management facilities by minimizing the environmental risks related to the disposal of medical waste. While the lower-level model is to determine the waste collection plans by only...
