Dear Colleagues,

Over the last few decades, a large amount of waste has been generated from industrial, domestic, and agricultural activities owing to population and economic growth. In addition, with technological and industrial advancement, new types of wastes, including polymeric, organic, and hazardous waste, have emerged. Failure to address their possible reuse, recycling, and treatment may have adverse effects on human health and the ecosystem. Therefore, an efficient waste utilization technique has to be established to alleviate the problems. Recently, the reuse of waste as a substitute or value-added material in geotechnical and geoenvironmental applications has been gaining interest, which is one of the most effective ways to reuse waste. In the establishment of efficient waste utilization, understanding its characterization, different technical and environmental factors, and their relationship needs to be considered systematically. Although waste has been reused in geotechnical and geoenvironmental applications, there are many challenges for both academia and industry which require systematic investigation. This Special Issue aims at current practices in the utilization of various waste for soil applications, their interaction, and their effect on mechanical, hydraulic, physical, chemical, electrical, and thermal characteristics integrated with economic, social, and environmental considerations. The Special issue calls for original research and reviews manuscripts, including case studies for waste utilization in the field geotechnical and geoenvironmental applications.

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. Sustainability 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 2400 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.
