Dear Colleagues,

One major challenge throughout the world is the treatment of domestic waste, either municipal solid waste or wastewater. The world’s natural resources are declining, and all waste types should be recycled to be used as new materials. Organic waste contains nutrients that must be recycled to food production in agriculture.

Domestic waste contains a mixture of chemicals, plastics, metals, and organic material, which makes recycling challenging. Some materials are harmful in the environment. Sustainable strategies are needed to collect, sort, and treat domestic wastes in a sustainable manner. The strategies will be different in different parts of the world. In industrialized countries, where waste treatment management is more sophisticated, strategies are different from those of developing countries. In many developing countries, wastes are not sorted or collected using any centralized operations, and thus, innovations and new engineering and management are needed.

This Special Issue aims to collect studies on innovations to solve challenges in domestic waste recycling. Applied research examining biotechnological innovations to treat domestic waste is welcome to this Special Issue. Any biological innovative and sustainable management techniques are welcome. The scale of management technology can be anything between one household and a large centralized treatment. As the substrate to study, mixed wastes collected and sorted from households are preferred over agricultural side-products such as hay and vegetable wastes alone. Focusing not only on the process of the technology but also on the mechanisms behind the observations is highly appreciated.

The scope of this Special Issue covers the following topics:

• Biological treatment technologies for domestic waste;
• Biological treatments such as composting, vermicomposting, and anaerobic digestion of organic waste;
• Different amendments, such as microbes and biochar, to improve the biological process;
• Destruction of environmental contaminants in domestic waste treatment;
• Utilization of material produced in agriculture.

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.
