In today's society, plastic packaging spreads throughout the city, causing many problems. According to the survey of environmental food rural areas (2008), the amount of packaging waste in the UK has reached approximately 10.7 million tons, which is being handled. Obviously, the problem of waste is very serious. In this article we analyze some of the problems caused by this phenomenon, then propose some solutions and criticize them. Several problems have arisen as people generate large amounts of waste.
Incineration is carried out on a large scale on a small scale by individual and by industry. It is used to process solid, liquid and gaseous waste. It is regarded as a practical way to handle certain hazardous waste such as biomedical waste. Incineration is a controversial waste disposal method due to problems such as emissions of gaseous pollutants. Incineration is common in countries with lack of land like Japan. These facilities usually do not require as much land as landfill. Waste energy (WtE) or waste energy (EfW) is a broad term for facilities that burn waste in furnaces or boilers to produce heat, steam or electricity. Combustion in incinerators is not necessarily perfect, and people were concerned about the pollutants emitted from the incinerator chimneys.
Incineration is the process of burning solid organic waste to convert it to residue and gaseous products. This method can be used to treat solid residues from municipal solid waste and wastewater treatment. This process reduces the amount of solid waste from 80% to 95%. Incineration and other high-temperature waste treatment systems are sometimes called "heat treatment". The incinerator converts the waste into heat, gas, steam and ash
Large amounts of solid waste generated from municipalities (such as markets) are often not regulated. Since garbage is dispersed, garbage collection and disposal do not collide with the amount of garbage that occurs every day. In the market, not only a large amount of solid waste is generated, but also various types of waste are generated. Since various types of waste are generated in the market, it is necessary to properly manage it in order to avoid adverse effects on the environment, health and ecology. Therefore, in this article, we will explain challenges and problems related to the management of solid waste generated in the three main markets of Zanzibar City (Mwanakwellkwe, Darajani, Mikununi). Several methods were used to conduct this survey, such as questionnaires, interviews and direct observations. The logical conclusion is that all informal dump sites need to be replaced with Kibele's dump site.
