Abstract
Over the past years, the high generation of municipal solid waste has been identified as a considerable global environmental issue, due to population growth, economic development, and the industrial revolution. The present research study was conducted to evaluate the quantity, ingredients, and generation of municipal solid waste (MSW) in Pshdar district during winter and summer in 2019. The results revealed that the average of solid waste production in the district reached 94 tons/day and 0.761kg-capita/day. The most abundant MSW constituents are organic matter forming 75.71% of MSW of the district, followed by 13.18% of plastic content and the least ingredient is metal 0.93%. While the average ratio of paper and cardboard, textile and leather, and glass waste ingredients are 3.74%, 4.85%, and 1.66% respectively. The seasonal effect on solid waste content has been observed obviously in this research, more specifically in organic matter and textile & leather, as well as in waste generation rate. Organic matter increased from 70.73% to 80.68% from winter to summer, while, percentage of textile and leather significantly declined from 6.93% to 2.76% from winter to summer. Similarly, waste generation rate was reduced from wet to dry season from 0.846kg-cap/day to 0.676kg-cap/day.

IntroductionHuman started to think about innovative methods to solve this problem that has threatened this planet
This research study mainly focused on determining the municipal solid waste (MSW) compositions; and in order to get more precise data about how the quantity and ingridents on MSW are influenced by seasonal variations (as shown in the study by (Gintaras D., et al, 2014), this study conducted in two different seasons: winter and summer
In order to calculate the waste generation rate, all MSW samples were collected from different zones, weighed during the analysis period and an average of all wastes generated in both seasons were evaluated as 104.22 tons and 83.31 tones for winter and summer respectively
Summary
Human started to think about innovative methods to solve this problem that has threatened this planet. The solid waste has been discarded away from residential area. The solid waste management issues have been started with preliminary modern human life on the earth planet. It has become one of the most considerable global problems as a result of population growth, economic development and industrial revolution. Inadequate management of solid wastes influenced the biotic environment as well as public health, sometimes causing serious health problems. Today’s world for sustainable development purpose requires accurate solution to different solid waste issues (Ministry of Environment, 2014). The global projected waste generation is expected to upsurge to 2.59 billion tons of waste annually, and by 2050, waste generation through the world is anticipated to reach 3.4 billion tons (Silpa Kaza, et al, 2018)
