In the present research, waste PVC film plastics were pulverized by heat treatment at different temperatures without using water, and the de-chlorination ratio and properties of the pulverized products closely related to blast furnace injection as solid fuel were further analyzed. The process not only help efficiently use the PVC waste plastics
A significant development in solid-waste treatment and disposal practices was marked by the construction of the first refuse incinerator in England in 1874. By the beginning of the 20th century, 15 percent of major American cities were incinerating solid waste. Even then, however, most of the largest cities were still using primitive disposal ...

Solid-waste treatment and disposal. Once collected, municipal solid waste may be treated in order to reduce the total volume and weight of material that requires final disposal. Treatment changes the form of the waste and makes it easier to handle. It can also serve to recover certain materials, as well as heat energy, for recycling or reuse.
Due to the significant impacts posed by MSWs; Government on one hand should provide recycling and treatment facilities for effective management MSWs, and effective legislation on the other hand in order to deter precarious dumping. ... 2.2 Process of Municipal Solid Waste Management in Nigeria . The process of municipal waste management ...
The term "Solid Waste" based on the Resource Conservation and Recovery Act (RCRA), means any garbage or refuse, sludge from water and wastewater treatment plants, or air pollution control facilities, and other discarded material, resulting from industrial, commercial, mining, and agricultural operations, and from community activities.
New technology of efficient pulverization of simulated municipal solid waste based on low temperature heat treatment and properties of pulverized product for blast furnace injection. Zhirui Nie Guang Wang Hongqiang Zhang Jing-song Wang Q. Xue
Treatment of waste to remove or inactivate contamination can render the waste less toxic, which can lead to more options for waste transport and disposal. Treatment can also be used to reduce the volume of waste. Volume reduction is especially needed for certain types of waste either due to transportation constraints or lack of …
Stainless steel dust is a solid waste and contains a large number of valuable Fe, Cr, and Ni metal oxides, which should be recovered efficiently.Through direct reduction and self-pulverization separation, the goals of high metal recovery ratios and grades in the new process of comprehensive stainless steel dust utilization were achieved.
A new processing method to compatibilization called solid state shear pulverization is applied to unmodified polymer blends. This process is environmentally friendly that can be used to produce powder from both and commingled polymeric waste feedstocks in an industrially applicable manner.
Solid waste generation from industries as well as daily societal necessities has caused enormous environmental concerns due to the limited amount of treatment available to safely and efficiently recycle them (Zimmerman et al., 2020; Ratti, 2020).These waste materials could range from particulate matter, food wastes and elastomers.
Pyrolysis has been examined as an attractive alternative to incineration for municipal solid waste (MSW) disposal that allows energy and resource recovery; …
The selection criteria for the solid waste treatment techniques mainly depend on the quality and quantity of the waste generated. In addition to that, many other factors are to be considered while the selection of waste management techniques, such as social, environmental, technical, financial, geographical, and political factors [35].The cost is …
The hydrogen concentration on a dry ash-free basis decreased with temperature from 3.3 % at 600 • C to 1.7 % at 900 • C. Cyclone char, most notably, retains more hydrogen and oxygen at 600-700 ...
A combination of solid-rich waste and liquid effluents can form ideal production media; however, economic aspects must be analyzed before using the combined waste streams. Pectin, fibers, flavors, colorants, and some antioxidants obtainable from plant-based FW serve as ingredients for novel foodstuffs.
In addition, the process is affected in a complicated way by the physical properties of the pulverized material, the pulverization environment, etc. Therefore, it is difficult to clearly explain the …
The paper proposes a critical assessment of municipal solid waste gasification today, starting from basic aspects of the process (process types and steps, …
The recovery of energy from municipal solid waste(MSW) is of great importance for the sustainable development of human society. Transforming MSW into fuel is a very good technology, where pulverization pretreatment is a key point for the …
Recent decades have seen a rapid increase in the amount of human-generated waste. Solid waste management has become a critical issue to the environment [].The main reasons for that are the growing rate of technological progress and consumerist lifestyle [].According to information published by Eurostat, the amount of generated …
Pulverization of Waste Polyvinyl Chloride (PVC) Film by Low Temperature Heat Treatment and Properties of Pulverized Product for Blast Furnace Injection as Alternative Fuel April 2022 Polymers 14(9 ...
In this paper, the authors focus on a novel method for the pulverization of waste plastics by low temperature heat treatment of mixed pulverized coal and waste plastics (Li et al., 2007; Asanuma et al., 2014; Murai et al., 2015), which is more easily realized at industrial scale and is designed for the blast furnace injection processing …

This Special Issue on "Advances in Solid Waste Treatment Technology and Contamination Remediation" seeks high-quality works focusing on laboratory testing, field testing, and numerical modeling of solid waste. Topics include, but are not limited to: Processing and utilization of municipal solid waste, construction waste, and industrial waste.
The quantity of waste generated doubles the total population. Municipal solid waste management is an important and complex challenge that is faced by many countries in finding an appropriate solution (A.H. Khan et al., 2022; Lin et al., 2022). Municipal solid waste can be divided depending on the source, property and nature.
