1. Introduction. In Urban systems solid waste is generated on a day-to -day basis and needs to be administered daily. Solid waste management is an essential practice adopted by the local authorities to maintain hygienic surroundings in residential areas .The role of these local bodies becomes much more critical in natural disasters such as hurricanes earthquakes floods pandemics
For sustainable management of solid waste effective planning and development strategies about the quantity and categories of such wastes are of great importance. Thus the most important processes are quantification and characterization of all the sustainable solid waste management systems according to Senzige et al. . At a particular place studying the composition and the categories of solid waste
solid waste components • Step Two Convert moisture content into hydrogen and oxygen • Step Three Revise Composition in Kg • Step Four Compute Molar Composition of Waste • Step Five Compute Normalized Mole ratio
The management practices for municipal solid waste consists of sequential platforms such as (i) generation and initial sorting of wastes at the origin (ii) collection of waste through garbage collection trucks by the local municipality (iii) transfer of wastes to material recovery facilities and (iv) disposal processing and recycling of wastes.
Waste composition differs across income levels reflecting varied patterns of consumption. High-income countries generate relatively less food and green waste at 32 percent of total waste and generate more dry waste that could be recycled including plastic paper cardboard metal and glass which account for 51 percent of waste.
Plastic polymeric material that has the capability of being molded or shaped. This property of plasticity often found in combination with other special properties such as low density low electrical conductivity transparency and toughness allows plastics to be made into a great variety of products.

While plastic products bring convenience to human beings there are also great health and environmental threats. This paper reviews a range of management recycling methods for the increasingly severe problem of discarded plastics and briefly summarizes the advantages and disadvantages of some methods as well as lists several important value-added applications of waste plastics.
Waste generation. According to the 1999 State of Environmental Report for South Africa ( DEAT 1999 ) the country generates over 42 million m 3 of solid waste every year. This is about 0.7 kg per person per day compared to 0.73 kg 0.87 kg and 0.3
Based on current solid waste plans China could face an 8-fold increase in its country-wide waste management budget between now and 2020 (rising from today’s estimate of 30 Billion RMB to about 230 billion RMB). The need for increased budgets will be most severe in smaller cities (those under 1 000 000 people).
suited for this purpose (s olid waste fuel wood waste oil tyres solvents). So far implementing acts have been adopted for metal glass and copper. Treatment methods vary across waste categories. Eurostat data for the EU28 in 2012 indicate that across all waste categories 48 of waste collected is landfilled and 36 is recycled.
MSW is to a high extent a renewable fuel but plastic rubber etc. can amount to 50 of the carbon content in the waste. Recycling of plastic is in general environmentally favourable in comparison
Composition of Solid Waste. If solid wastes are to be used as fuel the four most important properties to be known are Proximate Analysis Loss of moisture (temp held at 105 C) y/solid-waste-management • Solid and Hazardous Waste ManagementM.
Plastic solid waste (PSW) is derived from oil and has a recoverable energy in some cases comparable to other energy sources. Direct incineration via one or two stage combustion technologies can certainly reduce the volume of PSW as well as the dependence on fossil fuels which as a result can lead to a better conservation of natural resources and integrated waste management schemes.
Waste reduction presents significant opportunity to conserve finite resources through a nationally recognised waste management hierarchy which lists practices from most desirable to least desirable i.e. avoidance reduction reuse recycling and recovery. As waste management initiatives progress up the hierarchy consideration needs to extend

Material flow analysis has been used to assess the flows and stocks of materials through a particular system defined in space and time in order to characterize scale and connections between sources conversion processes and sinks of the material in question .Our aim was to characterize the flows of plastics through the US economy in a given year 2017.
It shows that Chemical recycling (depolymerization) primary and mechanical recycling and energy recovery can be used to reduce the footprints by recovering energy from plastic and avoid the energy-consuming pathways (extraction to polymerization) to produce plastic . International Solid Waste Association (ISWA) has covered three overall goals to manage the waste during COVID-19 pandemic (1) The waste management

The waste plastic materials were collected from various solid waste management sectors and cut down into small piece of size approximately 0.50–1.2 cm 2. Water was used to wash the plastic materials in order to remove the dirt and foreign particles and kept them in an electric oven at 100 to 120 °C for removing moisture.

Municipal solid waste (MSW) reflects the culture that produces it and affects the health of the people and the environment surrounding it. Globally people are discarding growing quantities of waste and its composition is more complex than ever before as plastic and electronic consumer products diffuse. Concurrently the world is urbanizing at an unprecedented rate. These trends pose a
The main aim of this work is to reduce the plastic waste that is rising in the present world and to achieve this a system is designed incorporating a plastic extruder which plays a prominent part in recycling waste plastic into useful products. This work uses waste plastics and converts them into building materials with the help of an extruder thereby reducing the plastic waste which is a

Abstract. Plastic pollution is a pervasive and growing problem. To estimate the effectiveness of interventions to reduce plastic pollution we modeled stocks and flows of municipal solid waste and four sources of microplastics through the global plastic system for five scenarios between 2016 and 2040.
