Application of Natural Resources for Sustainable Packaging

Dear Colleagues,

Natural resources play a pivotal role in the quest for sustainable packaging-based solutions. In utilizing sustainable packaging, we aim to minimize environmental impact throughout the lifecycle of such packaging, from production to disposal. Utilizing natural resources in packaging materials can significantly contribute to achieving this goal.

Wood-based materials, such as paper and cardboard, are among the most commonly used natural resources in packaging. These materials are renewable and biodegradable; they have a relatively minimal environmental footprint compared to traditional plastic packaging. Moreover, advancements in wood-based packaging technology, such as innovative pulping and processing methods, have enhanced their strength and durability, thereby making them suitable for a wide range of products.

Another prominent natural resource for sustainable packaging is plant-based polymers, such as bioplastics. Derived from renewable sources like corn starch, sugarcane, or cellulose, bioplastics offer a renewable alternative to conventional petroleum-based plastics. Bioplastics can be biodegradable, compostable, or recyclable, depending on their composition, making them environmentally friendly options for various packaging applications.

Furthermore, natural fibres from agricultural by-products, such as wheat straw, rice husks, or hemp, are increasingly utilized in sustainable packaging. These fibres can be processed into sturdy packaging materials that are biodegradable and compostable. By diverting agricultural waste from landfills and utilizing it for packaging, these materials contribute to reductions in waste and promote the principles of the circular economy.

Additionally, bio-based coatings and adhesives derived from natural sources, such as plant oils or resins, are utilized to enhance the performance and sustainability of packaging materials. These coatings provide barrier properties, moisture resistance, and adhesion while being biodegradable and non-toxic.

Harnessing natural resources for sustainable packaging will produce promising solutions for the mitigation of environmental concerns associated with traditional packaging materials. By embracing renewable materials, biodegradable options, and bio-based technologies, the packaging industry can minimize its ecological footprint and move towards a more sustainable future.

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 250 words) can be sent to the Editorial Office for assessment.

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. Applied Sciences 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.
