        Regarding to the variety of uses of steel in the world and widening its scope of application with the advancement of technology, steel production has changed to keep pace with advances in technology, following the changes; producers have tried to raise productivity and use of cheaper energy and fuels due to its geographical environment. There are the wastes in different stages of steelmaking (coke making, iron making and steelmaking). The generated wastes in this industry are with hazardous substances such as heavy metals, according to the classifications of the wastes, are classified as hazardous wastes. Therefore, identification and analysis and management of such waste in these industries are essential. The release of aforesaid hazardous wastes in nature can be had issues and problems for the environment and human health ultimately exceed the acceptable environmental conditions. The proper management of hazardous wastes in order to reduce and control pollution of the environment is utmost importance. Manuscript profile

        Today, with increasing in production and diversity expansion of dairy products in factories and production of whey products, this food product has become very important. Whey is a water-soluble part of milk that is obtained by adding acid, heating, and coagulating the cheese. This yellow liquid contains a lot of lactose and mineral compounds such as calcium and phosphorus, which is important to achieve in order to use as a food source and prevent environmental pollution. Since the wastewaters of the dairy industry have the highest levels of contamination, if the untreated wastewaters of this industry are discharged, serious environmental problems will be inevitable. On the other hand, a reduction in existing reserves and environmental problems followed by increasing use of fossil fuels has prompted researchers to produce new sources of renewable energy, and it can be said that new biological technologies, such as the use of whey as a way to produce biofuels, reduces the environmental problems of dischrging this kind of wastewaters into nature. Today, using biological technology, these compounds can be used to produce biofuels such as hydrogen, methane, and ethanol. So far, various methods and tests have been performed to produce these fuel sources and in this study, the effective strategies for recycling whey and preventing environmental damages are investigated.

        Rubber is one of the materials that are widely used in industry and when they expire, they fall into the category of hazardous wastes. The release of rubber wastes into the environment causes many problems, including diseases, their bad landscape in nature, and terrible fires caused by their accumulation and environmental pollution. Also, rubber can be reused due to its non-degradability and elastic properties; as a result, the management of worn tires has a particular importance. There are several ways to manage rubber waste that can be safe and effective when done properly. These methods include sanitary landfilling, incineration, pyrolysis, milling, reuse at various scales, and re-coating. In this article, each method is reviewed and their advantages and disadvantages are stated. Also, there are examples of different applications of rubber waste in various industries. Manuscript profile
