Abstract
Pyrolysis of municipal solid waste can take full advantage of energy and resource and avoid producing hazardous material during this period. In combination with mature metallurgical technologies of coking by coke oven, regenerative flame furnace technology and melting by electric arc furnace, technologies of regenerative fixed bed pyrolysis technology for household waste, co-coking technology for waste plastic and blend coal, and incineration ash melting technology by electric arc technology for medical waste were respectively developed to improve current unsatisfied sorting status of waste. The investigation results of laboratory experiments, semi-industrial experiments and industrial experiments as well as their economic benefits and environmental benefits for related technologies were separately presented.

Keywords: Municipal solid waste; Household waste; Waste plastic; Medical waste; Metallurgical technology. 1. Introduction
Municipal solid waste (MSW) includes partial household waste (HW), waste plastic (WP), and medical waste (MW) which has complex components. With the rapid development of economy and raised people’s standard of living, the quantity and lower heating value (LHV) of MSW has been rising year by year. It is shown that the LHV of HW in big cities such as Beijing and Shanghai, China has approached
6,200 kJ/kg, that the LHV of MW has already climbed to 10,000 kJ/kg due to packs of textiles, pledgets, mutilated bodies,

    Is Burning Trash Ana Baptista Summary

    Rethinking Waste Incineration for a Sustainable Future In the essay "Is Burning Trash a Good Way to Handle It?" Waste Incineration in 5 Charts," published in Open Washington Pressbooks, the author Ana Baptista raises awareness of the growing environmental and public health concerns connected to waste management. She argues that it’s an outdated waste management practice with a shrinking support base and that there is a better way to dispose of waste than by burning it. While the incineration plants currently used to burn waste, help generate electricity through the heat created during the process, the emissions released during this exchange do more damage to the environment compared to other sustainable forms of waste disposal.…

    Population Growth In Melbourne

    It to some extent reduces the urban sprawl and the need for further vegetation clearing for new suburbs. In other words, it saves some rural areas. They also advocate that encouraging urban consolidation may be one of the cheapest ways to lessen the cost of providing urban infrastructure like electricity, pipe water and sewerage when people are gathered in towns or cities. In addition, due to the economies of scale in the cities, both economic opportunities and people’s income would be increased. However, the issue of sustainability has emerged as a major concern for mega cities, where uncontrolled development and expansion of the city is a constant threat on environment. As a result of urban consolidation, the increased residential density has increased traffic flows and has required the provision of many more parking spaces. In relation to the high residential density, the city size as well as the land-cover pattern is changed. Buildings, roads and other infrastructure replace open land and vegetation; increased surfaces that were once pervious and moist become impervious and dry; increased multi-storey buildings that help surface areas absorb solar energy. All these changes cause the urban heat island effect…

    Comparison Between Electric Arc Furnace and Blast Furnaces

    Both blast and electric arc furnaces are used in industrial settings to heat and mold metal. A blast furnace is used to make steel from liquid iron, while an electric arc furnace is used to make steel from scrap material. Electric arc furnaces use two different types of electrical currents to create heat. Blast furnaces force air into the bottom of the furnace into a heated stove area. The heat from the blast furnace's stove area converts the forced air into heated air to melt metal.…

    Against Abortion (English Assignment)

    “I've noticed everyone who is for abortion has already been born” (Ronald Reagan). How would you feel if you never got the chance to experience anything? Or never got the chance to live? Even though we go through some tough times, everyone has those moments they wish they could re-live, but what if you didn’t even have a chance to make it to those amazing moments in life all because someone chose to abort her pregnancy and you were the baby in her womb? What if that child was to make a difference in the world? People don’t think about these things when they go into the abortion clinic. Why should abortion be legal if murder is a felony? That is the question that gets people speechless. Although babies are not fully developed when this process is taking place, they are still a living thing with living cells in them and they deserve to have a chance at life. Abortion should be illegal because you are committing murder of a human being, it causes traumatizing damage physically and/or emotionally, and you will look down upon the choice you made later on in your life.…

    Explain How Urban Heat Islands Develop? to What Extent Uhi Influence

    Secondly, the intensity of the UHI is enhanced by the emission of heat trapping pollutants into the urban atmosphere along with the heat lost from homes, factories and vehicles. As urban areas are often inhabited by large numbers of people, heat generation by human activity also contributes to the UHI. Such activities include the operation of automobiles, air conditioning units,…

    Pyrolysis has the potential of transforming used tyres into useful recyclable products. This paper demonstrates the conversion of scrap tyres into its primary products which are Pyro Oil and Carbon Black and a secondary value added compound, Activated Carbon. Further, the objectives of the work also include optimization of parameters such as temperature and feed size to study the efficiency of pyrolysis at different conditions. Three different set ups are used for pyrolysis namely the lab scale pyrolysis unit, the pilot plant scale pyrolysis unit and a conventional unit.…

    What is the burner of the rotary kiln?

    Rotary kiln is the main form of wear of gear damage after severe not ensure normal meshing and change, even if the tooth tip sharpening, are hongxingly not broken teeth phenomenon. In order to reduce wear, in the repair of kiln ring gear made the flame surface quenching, quenching and tempering after. After years of use, wear very slight. Along with the high grade iron ore mining continuously to begin to dry up, and the ore prices continue to rise, low grade iron ore and compound symbiosis ore become of great exploitation value, and become the development direction of the future. The experiment USES iron ore mineral composition complex, basically have siderite, limonite, diamond magnetite, all kinds of mineral close symbiosis, hybrid distribution, very fine disseminated extent, the comprehensive quality is low, the ore sorting is very difficult, so use rotary kiln has certain advantages.…

    Pyrolysis

    ABSTRACT Innovations being into management level may take its part as process, product, technology and strategy innovation. A process innovation that meets the energy crisis as well as requirement of effective waste management is proposed in this work. Plastics are inexpensive, lightweight and durable materials, which can readily be moulded into a variety of products that find use in a wide range of applications. As a consequence, the production of plastics has increased markedly over the last 60 years. However, current levels of their usage and disposal generate several environmental problems. Waste plastic disposal and excessive use of fossil fuels have caused environment concerns in the world. Both plastics and petroleum derived fuels are hydrocarbons that contain the elements of carbon and hydrogen. The difference between them is that plastic molecules have longer carbon chains than those in LPG, petrol, and diesel fuels. Therefore, it is possible to convert waste plastic into fuels. The non-catalytic pyrolysis process is the nearest technique to commercialization considering the collection and recycling processes of waste plastics. Unlike incineration or gasification, non-catalytic pyrolysis yield fuel that is almost equivalent to the fractionating column of diesel. The existing use of pyrolysis and the risks involved in it proves that the amount of individual scope was only used for the process of extraction of bio-char for agricultural purpose. But coming to the industry or manufacturing level, the “BIO” concept is altered to meet the future fuel requirements. This process helps the industries to avoid relying heavily on fossil fuels for logistics and other operations.…
