        Industrial development and rapid population growth due to the increase in consumed materials and the consequent increase in industrial waste is one of the challenges in the world. The purpose of this study is to investigate the quantity of industrial waste production in the industrial group of plastics and synthetic rubber in Guilan province and the conditions of resulting pollution. The results of this study show that the major industrial wastes identified in this group include plastic waste, paint cans, cardboard waste, paint powder, packaging strap, polymer waste, polymer sludge, wood waste, glass and carbon fiber waste. Plastic waste with 136.08 tons is the highest and paint powder with 0.04 tons is the lowest industrial waste produced in this group. The used oil with a total amount of 14092 liters per year is the only hazardous waste identified in this group. From the present study, it is concluded that the main management methods used in this industrial group are recycling and sales, but hazardous waste is not disposed of properly. The proposed method for used oil is refining. Manuscript profile

        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.
