Description of Case

Rapid industrialization and uncontrolled and unmonitored urbanization have created serious problems of solid waste disposal in developing countries . Many cities in those countries are facing problems with solid waste that has a high fraction of putrescible organic waste that easily can be degraded and cause serious environmental and health risks. Proper management and treatment of municipal solid waste (MSW) can prevent the heaping of solid waste piles in urban or periurban areas, thus avoiding groundwater pollution, land contamination, greenhouse gas emission, and many other environmental problems.

Introduction

The energy of ambient vibrations and ocean waves has long been known.  The energy of the ambient vibrations was too small for almost all applications four decades ago.  The energy of the ocean waves was significant, but the cost of the development and installation of a huge device in the middle of the ocean was prohibitive compared with using relatively cheap oil.  The advancement of technology, increasing needs for energy, and limitations of other energy sources have been changing the feasibility calculations.  There has been a significant effort in the research community, government agencies, and private companies to generate electricity from the oscillations described above.
