Metallurgical recovery of metals from electronic waste: a review.

Modification in polymeric structure of plastic material can be brought either by conventional chemical means or by exposure to ionization radiation from ether radioactive sources or highly accelerated electrons. The prominent drawbacks of chemical cross-linking typically involve the generation of noxious fumes and by products of peroxide degradation. Both the irradiation sources have their merits and limitations. Increased utilization of electron beams for modification and enhancement of polymer materials has been in particular witnessed over the past 40 years. The paper highlights several recent cases of EB utilization to improve key properties of selected plastic products. In paper is provided a survey of radiation processing methods of industrial interest, encompassing technologies which are already commercially well established, through developments in the active R&D stage which show pronounced promise for future commercial use. Radiation cross-linking technologies discussed include: application in cable and wire, application in rubber tyres, radiation vulcanization of rubber latex, development of radiation crosslinked SiC fiber, polymer recycling, development of gamma compatible pp, hydrogels etc. Over the years, remarkable advancement has been achieved in radiation processing of natural polymers. Role of radiation in improving the processing of temperature of PCL for use as biodegradable polymer, in accelerated breakdown of cellulose into viscose and enhancement in yields of chitin/chitosan from sea-food waste, is described.

Nitrogen oxides (NOx) and sulfur dioxide (SO2) are the main air pollutants. Both of them are mostly formed during the process of fossil fuels combustion, while some processes generate very high concentrations of NOx and SO2. In this review the authors describe and summarize the currently used methods and the new techniques that are under investigation. They also give a detailed description of the regulations and sources of SO2 and NOx emissions, as well as their impact on human health and the environment. The authors focus primarily on the environmental protection technologies used in power plants, vehicles, ships, and the chemical industry.
