Authors must register before submitting a manuscript. The submission process is designed to ensure that manuscripts meet the journal's standards for quality, originality, research integrity, and Publishing Ethics.

Authors should submit manuscripts through the journal's online submission system. Before submission, authors should ensure that the manuscript is consistent with the journal's Aims and Scope, prepared according to these Author Guidelines, and accompanied by all required information and supporting documents.

After submission, the manuscript may undergo an initial editorial assessment covering completeness, scope, originality, research integrity, and suitability for peer review. The manuscript may also be checked using iThenticate or an equivalent similarity-checking service. Manuscripts that pass the initial assessment may be sent for peer review.

The journal follows a double-blind peer review process, in which the identities of authors and reviewers are not disclosed to each other during the review process. Authors will be notified of editorial decisions by email and may be invited to revise and resubmit their manuscripts when appropriate.

Authors should provide their ORCID iD during submission. Where available, ORCID identifiers may be displayed with the published article.

Authors who do not yet have an ORCID identifier can register for a free ORCID iD.

Authors are encouraged to review the following checklist before submitting a manuscript:

In addition to the main manuscript, authors should provide the following documents or information where applicable:

Authors should avoid unsupported claims of novelty or significance, excessive technical jargon, unexplained abbreviations, and statements that cannot be directly supported by the manuscript.

Global Waste Valorization accepts several types of scholarly contributions. Authors whose work falls within the journal's scope but does not clearly fit one of the categories below may contact the editorial office before submission.

Word counts are indicative and may vary according to the nature of the research. References, figure captions, and tables are generally not included in the main word count.

The following structure is recommended for Research Articles. Review Articles, Short Communications, Editorials, and other article types may follow a more appropriate structure according to their purpose and content.

Title

The title should be concise, informative, and accurately reflect the content of the manuscript. Titles should generally not exceed 20 words and should avoid unnecessary abbreviations, excessive punctuation, and obscure terminology.

Abstract

The abstract should be limited to 200–250 words and provide a concise, self-contained overview of the study. For Research Articles, authors are encouraged to organize the abstract around the following elements: Background, Methods, Results, Conclusions, and Significance.

References should not be included in the abstract. Unexplained abbreviations should also be avoided.

Keywords

Authors should provide 3–8 keywords following the abstract. Keywords should accurately represent the subject of the manuscript and should be separated by semicolons.

Authors are encouraged to use established terminology that is commonly used in relevant scholarly literature and indexing databases. Keywords should complement rather than simply repeat the title.

Introduction

The Introduction should provide a concise literature-based overview of the research background and current state of knowledge. It should identify relevant knowledge gaps or unresolved problems and clearly state the rationale, objectives, and significance of the study.

Section Headings

Manuscripts should use a clear and consistent hierarchical heading system. Numbered headings are recommended as follows:

• Main headings: 1, 2, 3, etc.
• Subheadings: 1.1, 1.2, 2.1, 2.2, etc.
• Sub-subheadings: 1.1.1, 1.1.2, etc., where necessary.

Materials and Methods

This section should provide sufficient detail to allow readers to understand and, where appropriate, reproduce the research. Authors should describe materials, waste streams, sampling procedures, pretreatment methods, characterization techniques, experimental conditions, conversion or recovery processes, analytical methods, statistical procedures, models, software, instruments, and other relevant procedures as appropriate to the study.

Methods based on previously published work should be appropriately cited. Any substantial modification of an established method should be clearly described.

Results

The Results section should present the principal findings in a clear and logical order. Results should be supported by appropriate tables, figures, statistical analyses, or other evidence where applicable. Extensive interpretation should generally be reserved for the Discussion section.

Discussion

The Discussion should interpret the findings in relation to previous research and the objectives of the study. Authors should address the significance and implications of the findings, relevant limitations, and potential applications for waste valorization, resource recovery, environmental sustainability, circular economy, or related areas where appropriate.

The Discussion should not simply repeat the Results. A combined Results and Discussion section may be used when appropriate.

Conclusions

The Conclusions should summarize the principal findings and explain their relevance to waste valorization and related fields. Authors should avoid introducing substantial new information that has not been presented and discussed elsewhere in the manuscript.

Author Contributions

For manuscripts with multiple authors, a statement describing the individual contributions of each author should be included. Contributions should accurately reflect the work performed by each author and should comply with the journal's authorship requirements.

Publishing Ethics

Authors must comply with the journal's Publishing Ethics requirements. Where appropriate, the manuscript should include relevant statements concerning research ethics, authorship, conflicts of interest, data availability, and other applicable ethical matters.

Funding

Authors should disclose all financial support received for the research or publication of the manuscript.

If the research received no external funding, authors may use the following statement:

For funded research, authors should identify the funding organization and, where applicable, the grant number:

Artificial Intelligence and Generative AI

Authors should disclose the use of artificial intelligence or generative AI tools when such tools have materially contributed to the preparation, analysis, generation, or modification of the manuscript or research materials, where disclosure is relevant under the journal's policies.

AI tools should not be listed as authors. Authors remain fully responsible for the accuracy, originality, integrity, and appropriate attribution of the submitted work, including any content generated or assisted by AI tools.

Figures, Tables, and Equations

All figures and tables should be cited in the text and placed near their first relevant citation rather than collected only at the end of the manuscript.

Figures and tables should be numbered consecutively and independently, for example:

Each figure and table should have a concise and informative title or caption. Figure legends should explain symbols, abbreviations, panels, and other information necessary to understand the figure.

Figures should be of sufficient resolution for publication. Authors must ensure that all figures, tables, photographs, maps, and other third-party materials are used with appropriate permission and attribution where required.

Equations should be editable and should not be submitted solely as images. Equations should be numbered consecutively where numbering is necessary, with equation numbers placed consistently throughout the manuscript. Authors are encouraged to use an appropriate equation editor such as MathType or the built-in equation editor in Microsoft Word.

The journal uses a numbered citation system for in-text citations. References should be numbered consecutively according to their first appearance in the text and enclosed in square brackets, for example [1], [2], and [3].

Each numbered citation must correspond to a complete entry in the reference list. The reference list should follow APA 7th edition bibliographic principles, while references are numbered and arranged according to their order of first citation in the manuscript.

Authors are responsible for ensuring that all references are accurate, complete, and verifiable. Authors should verify the authors, title, publication details, and DOI or URL of each reference before submission.

Where a DOI is available, it should be presented in the form:
