Special Issue Information

Dear Colleagues,

With the development of the agricultural economy, the amount of agricultural waste is gradually increasing. Without better technical measures to deal with agricultural waste, it will have a large impact on the environment. On the other hand, If agricultural waste is used effectively and with low carbon output, it will become a valuable resource and will be able to be converted into renewable energy and series products.

The purpose of this Special Issue is to be an important source of information that aims to increase the standards of discussions, analyses, and evaluations related to the low-carbon utilization of agricultural waste. The issue will cover research within the field of renewable energy technology, such as pyrolysis technology, hydrothermal carbonization technology, biogas technology, and other related sciences, with a strong focus on the low-carbon utilization of agricultural waste. Authors are encouraged to submit their contributions based on the following current and relevant research topics:

  • Characteristics, resources, and distribution of agricultural waste;
  • Pretreatment, thermochemical, and biochemical utilization of agricultural waste;
  • Collection, transport, and storage of agricultural waste;
  • Carbon capture, storage, and utilization of agricultural waste;
  • Extraction of value-added compounds from agricultural waste using green technologies;
  • Opportunities, challenges, and policy related to agricultural waste.

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).

The harmless disposal and resource utilization of human feces is important to the sanitation process. Hydrothermal liquefaction (HTL) can convert toilet feces into bio-crude oil and reduce waste. In this study, an integrated eco-toilet system was developed by combining vacuum micro-flush toilets with a continuous hydrothermal liquefaction reactor. The system operated stably for over 10 h. This system can serve 300 households and save 2759 m3 of water per year compared to traditional flush toilets. The energy recovery from the feces was 2.87 times the energy consumed for the HTL process. The HTL bio-crude oil yield was 28 wt%, and the higher heat value (HHV) of the bio-crude was 36.1 MJ/kg. The biochemical compounds of the bio-crude oil consisted of acid ester, hydrocarbons, phenols, and a nitrogenous heterocyclic compound. The carbon in the human feces was mainly transferred to the bio-crude oil, while nitrogen was mainly transferred to the aqueous phase product. The post-HTL aqueous stream could be treated and used as fertilizer. This system achieves energy self-sufficiency, along with water and energy savings. This integrated eco-toilet effectively converts feces into bio-crude to realize waste reduction and resource utilization of human feces. Full article
