Special Issue Information

Dear Colleagues,

Hazardous wastes that need treatment or disposal may be freshly generated from industrial, private, or commercial operations; they may be old stored chemicals, or they may have been sitting in a dumpsite for many years.

Hazardous waste can exist as solid, liquid, or gas. A hazardous waste characteristic is a property which, when present in a waste, indicates that the waste poses a sufficient threat to merit regulation as hazardous. The U.S. EPA established four hazardous waste characteristics: ignitability, corrosivity, reactivity, and toxicity. Some examples of hazardous waste are halogenated and non-halogenated organic solvents, PCBs, and pesticides.

Hazardous waste can be treated by chemical, thermal, biological, and physical methods. Chemical methods include chemical precipitation, ion exchange, oxidation and reduction, and neutralization. Among thermal methods is high-temperature incineration, which can not only detoxify certain organic wastes but also destroy them. The biological treatment of certain organic wastes, such as those from the petroleum industry, is also an option. One method used to treat hazardous waste biologically is called landfarming. Microbes can also be used to stabilize hazardous wastes on previously contaminated sites; in that case, the process is called bioremediation. When plants are used to decontaminate sites, phytoremediation and phytoextraction are applicable technologies. Landfilling is the other primary land disposal method for hazardous waste disposal in the United States.

Industries in the United States also dispose of their hazardous waste using a land disposal method called deep well injection. Liquid wastes are injected into wells located in impervious rock formations that keep the waste isolated from groundwater and surface water. Incineration is a controversial, but still common, method of handling hazardous wastes. Advanced oxidation techniques can also be used to destroy organic contaminants.

Chemical, thermal, and biological treatment methods change the molecular form of waste material. Physical treatment, on the other hand, concentrates, solidifies, or reduces the volume of waste. Physical processes include evaporation, sedimentation, flotation, and filtration. Another process is solidification/stabilization, which is achieved by encapsulating waste in concrete, asphalt, or plastic. Encapsulation produces a solid mass of material that is resistant to leaching. Waste can also be mixed with lime, fly ash, and water to form a solid, cement-like product.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2300 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
