Special Issue Information

Dear Colleagues,

The shift from abiotic to biotic resource usage and optimization of the same takes place by availing resource recovery and byproduct utilization from waste streams in a ‘circular bioeconomy’. The waste streams referred to in the focus above could have their origins in:

  1. Urban and rural systems (societies and commercial entities as points of final sale and consumption);
  2. Industrial systems (intermediate consumers of raw materials and providers of end-use products to (1) above);

The scope is restricted to biotic waste streams from (1) and (2) and does not include abiotic resources and collection and recycling of the same. This is in keeping with the Title—Resource Recovery in a Bioeconomy. One can conceive of a linear bioeconomy, or a circular bioeconomy, and in this Special Issue, we dwell on the latter and, thus, recovery of resources from waste streams in such an economy.

The purpose is to add to the knowledge that is building up rapidly in the 21st century, due to the growing awareness of resource scarcity and the urgent need for optimization of resource use, while also mitigating adverse environmental impacts. As far as situating this issue within existing literature is concerned, preference will be given to new and innovative ideas and applications (lab, pilot or commercial scale), as well as the application of sustainability analysis—environmental, economic, and social aspects. Insightful review papers encompassing findings from and critiques of publications related to resource recovery in a bioeconomy are also welcome.

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 papers will be 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 1800 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.

Techno-Economic and Partial Environmental Analysis of Carbon Capture and Storage (CCS) and Carbon Capture, Utilization, and Storage (CCU/S): Case Study from Proposed Waste-Fed District-Heating Incinerator in Sweden

Sweden aspires to become totally carbon dioxide-neutral by 2045. Indisputably, what is needed is not just a reduction in the emissions of CO2 (greenhouse gases in general) from the technosphere, but also a manipulated diversion of CO2 from the atmosphere to ‘traps’ in the lithosphere, technosphere, hydrosphere, and biosphere. The case study in this paper focused on Stockholm Exergi’s proposed waste-to-energy incineration plant in Lövsta, which is keen on incorporating carbon capture and storage (CCS), but is also interested in understanding the potential of carbon capture, utilization, and storage (CCU/S) in helping it to achieve ‘carbon-dioxide-negativity’. Waste-to-energy incineration plants (in cases where the petro-plastics in the waste mix can be substantially reduced) are a key component of a circular bio-economy, though the circularity here pertains to recovering energy from materials which may or may not be recyclable. CCS (storage in the North Sea) was compared with CCU/S (CO2 sintered into high-quality building blocks made of recycled slag from the steel sector) from techno-economic and environmental perspectives. The comparative analysis shows, inter alia, that a hybridized approach—a combination of CCS and CCU/S—is worth investing in. CCU/S, at the time of writing, is simply a pilot project in Belgium, a possible creatively-destructive technology which may or may not usurp prominence from CCS. The authors believe that political will and support with incentives, subsidies, and tax rebates are indispensable to motivate investments in such ground-breaking technologies and moving away from the easier route of paying carbon taxes or purchasing emission rights.
