The production of waste, especially with many countries emerging into powerful economies, has become a problem of such dimensions that something definite has to be done.Many new technologies are being developed to process, recycle and reuse waste, some combining waste treatment processes in the same plant to produce a variety of useful products such as electrical energy, diesel, heat, carbon black and other recyclable materials.
