Dear Colleagues,

Ecological Engineering can play a significant role in the Circular Economy by providing solutions to design and develop sustainable systems that integrate natural processes with human activities, reducing waste, minimizing pollution, and regenerating natural systems.

Considering that the main goals of the Circular Economy consist of simultaneously reducing the depletion of natural resources and mitigating the generation of waste, Ecological Engineering tools can be applied to attain those goals. Thus, both concepts are connected. This Special Issue intends to be a space to share works that strengthen this connection and boost future research in these fields.

This Special Issue aims to provide an opportunity for researchers to share their findings and insights on how to advance these fields and promote sustainability, including education and public engagement, which are critical routes to promoting awareness and understanding of Ecological Engineering and the Circular Economy.

In this SI, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

1. Bioeconomy;
2. Bioenergy systems and renewable energy;
3. Biomimicry;
4. Circular economy of biological resources;
5. Ecosystem restoration and conservation;
6. Environment protection;
7. Freshwater management and conservation;
8. GIS applications to resources management;
9. Green infrastructures;
10. Industrial ecology;
11. Life cycle assessment;
12. Nature-based solutions;
13. Resource recovery;
14. Sustainable agriculture and forestry.

We look forward to receiving your contributions.

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.
