There is a need in the railway industry for a flexible solution to the problem of service interruptions due to impacts on railway bridges from highway and other vehicle traffic. One such solution is the placement of a ... -
FEASIBILITY ASSESSMENT OF PRODUCTION OF LIQUID ORGANIC FERTILIZER (LOF) FROM FOOD WASTE FOR SUSTAINABLE WASTE MANAGEMENT
(2021-05-04)The increasing volume of food waste is responsible for the generation of potent greenhouse gases and is resulting in the wastage of valuable resources. In all regions of the world, the percentage of food waste in municipal ... -
Feasibility of Underground Freight Transportation (UFT) in Texas
(2015-12-17)The U.S. economy is expected to double in size over the next 30 years. Truck and rail freight traffic is expected to increase by approximately 45 percent. Air freight is expected to triple in response to demand for the ... -
Feasibility Studies To Support Landfill Gas Recovery In Ghana
According to World Bank Ghana generates 0.09 kg of solid waste per person per day, where there are only 4 engineered landfills in the country. In 2010, Ghana contributed to 0.13% of global greenhouse gases emissions, 10% ... -
Field And Experimental Studies To Assess The Performance of Stabilized Expansive Clay
(Civil & Environmental Engineering, 2007-08-23)A vast majority of the expansive soils are montmorillonite-rich clays, over consolidated clays and shales. The swell and shrinkage movements of expansive soil cause considerable damage to structures such as buildings and ... -
