The information technology is powered by electricity. Although its impact on Green House Gasses (GHG) is still rather limited, the next decade will show an explosion of its impact because technological innovations in data communication, information retrieval and datacenter operation will not compensate the increased need for energy of information technology. This paper approaches the problem no...

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 ...

A fundamental study of the characteristics of a sludge refuse-derived fuel (RDF) and the combustion behaviors were done. The test data demonstrate good results for the development of energy recovery technology of organic sludge or waste. The ash deposit formation propensity has been based on pretreatment, temperature and the ratio of organic sludge to sawdust. The usage of organic sludge and wa...

Microwave energy has been widely used in several domestic, industrial, and medical applications such as food sterilization, organic/inorganic syntheses, polymerization, dehydration, analyses and extraction, and biological destruction. This paper summarizes the potential applications of microwave energy as remedial alternatives for various types of wastes and diverse contamination of soils, slud...

In Kampala, Uganda, about 28,000 tonnes of waste are collected and delivered to landfill every month. Kampala Capital City Authority records show that this represents approximately 40 % of the waste generated in the city. The remaining uncollected waste is normally burnt and/or dumped in unauthorised sites, causing health and environmental problems. However, the organic fraction of domestic was...
