Special Issue Information

Dear Colleagues,

We are delighted to invite you to submit your latest research and findings on recovery technologies from wastewater and waste for an upcoming Special Issue of Processes, a scientific journal dedicated to the publication of innovative and high-quality research in engineering, chemistry, environmental science, and related fields.

As we face increasing pressure to address global challenges related to water scarcity and environmental pollution, innovative and sustainable approaches to resource recovery are critical.

Advancements in technology have led to the development of novel and innovative methods for recovering resources from waste and wastewater. These technologies address the increasing challenges of handling and disposing of waste, while also providing a source of valuable materials to be utilized in various industries.

Moreover, the recovered materials and resources from waste and wastewater can reduce greenhouse gas emissions, lower the demand for fossil fuels, and improve overall sustainability. Investing in waste and wastewater recovery technologies not only enables us to be more responsible for our waste management but also provides us with a new source of valuable resources, which are essential for a more sustainable and circular economy.

This Special issue will focus on new and emerging technologies for recovering resources from wastewater and waste that can reduce environmental impact and promote a more efficient resource use.

We welcome submissions on a wide range of topics related to resource recovery technologies, including, but not limited to, adsorption, membrane filtration, electrochemical processes, biotechnology, pyrolysis, and nanotechnology. We are particularly interested in research that provides innovative solutions to the challenges of wastewater treatment and waste management.

We encourage authors to submit original research articles, reviews, and perspectives that highlight the latest advances and challenges in the field of resource recovery. All submitted papers will undergo thorough peer review to ensure the highest standards of quality and scientific rigor.

We look forward to receiving your contributions and publishing groundbreaking research that will shape the future of resource recovery in the years to come.

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. Processes is an international peer-reviewed open access monthly 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.

The contaminant dyes that, even at low concentrations, may cause a series of adverse effects in humans and animals, and their removal by adsorption methods using alternative adsorbents as natural fibers, are regarded as a research topic that has become increasingly relevant. In this study, corn straw (CS), an agro-industrial residue, was used to remove dyes. The samples were characterized by ATR-FTIR, SEM-EDS, zeta potential, diffuse spectra, and colorimetry, before and after dye removal. The analyses allowed us to differentiate the morphology of CS after the treatment’s fiber on the adsorbent surface. The zeta potential showed a negative surface charge, but the acidic or alkaline treatment affected the surface charge of the sample, influencing the adsorption of cationic or anionic dyes. Adsorption data presented an increased removal when alkaline treatment was applied for the methylene blue (MB; qmax = 16.7 mg g−1), and the acid treatment was more effective for the Congo red (CR; qmax = 2.13 mg g−1). After color stability tests, it was observed that the anionic dye CR was more easily desorbed due to the surface charge of the adsorbent. Due to the chemical treatment, corn straw proved to be a good sustainable adsorbent for removing anionic or cationic dyes from aqueous media, contributing directly to the objective of sustainable development (#6—drinking water and sanitation) and with SDG numbers 3, 11, 12, 14, and 17.
