Fundamental understanding on the
collective behavior of particulate systems under combined
electro-mechanical loading environments is sought in several
interdisciplinary applications. A few examples are,in the
design of electrostatic granular valves, piezoelectric
powder compacts/sensors, electromechanical separators for
minerals and ores, powder injectors, and microbial
particulate fuel cells . The developments in micro/nano
technologies are pushing the limits of miniature
particulate...

Methane can be recovered from a variety of waste sources, namely agricultural waste, landfills and sewage sludge, by anaerobic digestion. This work concludes that the most feasible source for methane recovery is sewage sludge in West Yorkshire as this was deemed to be the Best Practicable Environmental Option (BPEO).The current UK infrastructure within agriculture presents logistic problems concerning the collection and transportation of waste sources making it impracticable. Landfill gas recovery has a large potential for energy production but current Government legislation eliminates it as...
