  Medical waste is a part of municipal solid waste which is classified as hazardous solid waste. One of the sources of medical waste is rural healthcare centers that are prominent because of having infectious waste. This research aims to study of medical waste in rural healthcare center, the quantity of waste and the method of waste management.This study was done in two countries of Rasht. The method was according to physical analysis and questionnaires.Total amount of medical waste in studied area is 274.3 kg/year. The amount of semi-household waste and medical waste are 75 and 25 percent, respectively. The result of questionnaires indicates lack of solid waste management system in rural healthcare centers of Rasht.The results reveal that the amount of medical waste in studied district is low. This amount is a great deal less than the amount of municipal hospital waste in other research. Although the amount of medical waste is negligible, lack of management system for medical waste separation, storage and disposal will cause undesirable impact on human and their environment.

  Natural gas and crude distillates such as naphtha from petroleum refining are used as feedstocks to manufacture a wide range of petrochemicals that are in turn used in the manufacture of consumer goods. Petrochemical plants are typically large and complex, and the combination and sequence of products manufactured are often unique to the plant. Petrochemical plants generate significant amounts of solid wastes and sludges, some of which are hazardous because of the presence of toxic organics and heavy metals. A good practice target for a petrochemical complex is to reduce total organic emissions (including VOCs) from the process units to 0.6% of the throughput. In this paper a variety of control of air emissions techniques is has been studied. Petrochemical waste waters often require a combination of treatment methods to remove oil and other contaminants before discharge. For solid and hazardous wastes, combustion (preceded in some cases by solvent extraction) of toxic organics is considered an effective treatment technology for petrochemical organic wastes. Steam stripping and oxidation are also used for treating organic waste streams. The generation of sludges should be minimized. Wastes containing toxic metals should be stabilized before disposal.

  Nowadays, environmental hazards that originated from inappropriate management of waste are one of the main problems of the country. Therefore, the development of waste management system and new and advanced technologies entry is necessary. Waste disposal by incinerator is an effective method. Unlike landfill, the use of incineration does not require long-term care and there is the possibility of energy extraction. One of the main disadvantages of this method is emission of air pollutants from the stuck of incinerators and management of the residual wastes such as ash. Therefore, selecting the best place for construction of the municipal waste incineration power plant will increase its benefits, reduce costs and eliminate community dissatisfaction by identifying and considering the involved and effective factors such as environmental, economic and social factors. In this paper, literature reviewes, searching for valid universal guidelines and the related articles in databases were used to introduce and compare the criteria mentioned for locating the municipal waste incineration power plant as one of the most important steps in designing a comprehensive waste management system.

  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.

  The paper is an update to the current status of laser drilling technique – the first fundamental change to rotary drilling. We begin with a brief history of already experiment which performed by another institutes. Next, we will discuss about effective parameters on reduce specific energy thereupon increase rate of penetration. Stress has been put on the effect of laser drilling on rate of penetration, drilling costs, and waste management that we discuss about these things in this research. Finally, experiments show that this advanced laser drilling technique can be efficient and economically for exchange with current rotary drilling. Laser drilling is found to be more efficient way to drill and perforate wells through hard rock formations encountered at greater depth. One of the major advantages of laser drilling is its potential to reduce drilling time. Laser cut drilling time reduced by not contacting the rock, eliminating the need to stop and replace a bit.

  Abstract One of the consequences of the developments of the world society in the last century is the development of urbanization and the focus of human communities in urban areas. The growth of population and tendency to urbanization is one of the developments of the current century, which intensified the use of resources and the production of waste. This increase in population along with the development of urbanization leads to the consumption of natural resources and as a result, it leads to production of all kinds of wastes. So, waste management in the world is becoming a big challenge in urban areas. This challenge is greater, especially in big towns. These wastes have not only entered the human ecosystem and the land of the earth, but also entered the seas and it has also left unfavorable effects on aquatic creatures. In order to keep pace with the needs of rapid economic development and continuous population growth, and also because of the vital role of waste management in preserving the environment and public health, marine waste management is one of the current priorities of societies. Disposal and accumulation of waste in the marine environment is one of the environmental threats that is increasing at a very fast pace. The purpose of this study is to review sources and collect information about the entry of plastic waste into the sea, its environmental effects and methods of marine plastic waste management.
