Despite public approval from the Danish Environmental Protection Agency (Miljøstyrelsen), farmers have proven reluctant to accept wastewater sludge as a source of fertilizer. They are in fact still being paid for accepting it. Based on interviews with key stakeholders, a review of the...

Life Cycle Assessment (LCA) is a technique to assess environmental impacts associated with all the stages of a product's life from cradle to grave. With raising human population and the increasing industrialization, there has been very substantial increase in waste products too. Nowadays the...

Waste heat recovery from high temperature slags represents the latest potential way to remarkably reduce the energy consumption and CO₂ emissions of the steel industry. The molten slags, in the temperature range of 1723–1923 K, carry large amounts of high quality energy. However, the heat...

The worldwide population increase and subsequent surge in energy demand leads electricity producers to increase supply in an attempt to generate larger profit margins. However, with Global Climate Change becoming a greater focus in engineering, it is critical for energy to be converted in as...

The discarded fruit and vegetable waste from the consumer and retailer sectors provide a reliable source for ethanol production. In this paper, an ethanol distillation system has been developed to remove the water contents from the original wash that contains only around 15% of the ethanol. The...

Drivers can easily feel fatigue and aprosexia due to the high temperature inside the locomotive driver cabin in summer. The current locomotive driver cabin air-conditioning system cannot meet the needs of operating condition and environmental protection. It is a very urgent task to develop an...

Modern large and fast ocean fishing vessels include mechanical refrigeration, but all of them consume precious fuel or electricity to achieve refrigeration. Fishing vessels with tonnage at about 100 tons cannot attach compressor-icemaker onboard because of their small horsepower of diesel...

The feasibility of recovering the waste heat from a small-scale incinerator (designed by Industrial Technology Research Institute) and generating electric power by a linear free-piston Stirling engine is investigated in this study. A heat-transfer model is used to simulate the integration system...
