Special Issue Information

Dear Colleagues,

We are inviting submissions to a Special Issue of Energies on the subject area of “Energy Conversion of Rural and Urban Residual Biomass”. In most regions in temperate climates, large quantities of biomass occur, which need to be managed but are rarely used. Such biomass comprises green cuts, leaf litter and material from landscape management, e.g., from nature conservation grassland, tree pruning, hedge trimming, etc. Household waste will not be covered in this issue. A common trait is that an energetic use of these materials would create no, or only small, conflicts with other utilizations, e.g., food or feed production. Considering the substantial costs and effort for management of these materials and the inadequate use on the one side and the need for renewable energy resources on the other side, much research is still needed to develop and implement strategies for a sustainable and efficient energetic utilization. This Special Issue aims to compile the existing knowledge about the state of the art and ideas on technical innovations in this area. Papers are preferably sought that critically examine the advantages and disadvantages of bioenergy concepts and techniques for residual biomass, by presenting pilot applications, desk-top reviews of case studies, proposal of analytical methods and tools.

Topics of interest for publication include, but are not limited to:

  • new biomass resources
  • new technical processes for energetic conversion of biomass
  • integrated analysis of conversion concepts including biomass collection, transport and storage
  • residue management after energetic conversion
  • assessment of efficiency of energetic conversion
  • socio-economic evaluation of bioenergy value chains
  • life-cycle assessment of concepts
  • legal framework development for enhanced implementation of novel concepts and improved sustainability
  • analysis of trade-offs in bioenergy production.

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. Energies 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 2600 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.

Biomass from forestry and agricultural sector provides an important contribution to encounter the government’s targets for increasing bioenergy production and utilization. Characterization of agricultural and forest wastes are critical for exploiting and utilizing them for energy purpose. In the present work agricultural and forest wastes and shrubs were sampled in two sites in north Portugal (Ave and Sabor basin) and subjected to Higher Heating Value (HHV) and chemical composition quantification. The HHV was evaluated according to the methodology described in Standard DD CEN/TS14918:2005. For the lignin content, the procedure was made by the Klason method and the extractives content was determined with the Soxhlet method. For agricultural and forest wastes the HHV values are identical with a range of 17 to 21 MJ·kg−1. However, shrubs biomass presentx slightly higher and statistically different values from agricultural and forest wastes, varying between 19 and 21 MJ·kg−1. Forest wastes contain higher levels of holocellulose compared to agricultural wastes and, with respect to extractive contents, this trend is the reverse. There is a general tendency for the woody components present thermo-chemical properties more suited for energy purposes, than the residues formed by the branches and leaves. Full article

Biomass-based energy accounts for a notable share of renewable heat and electricity generation in Germany. Due to limited alternative uses, biomass obtained from management of semi-natural grasslands is a potential feedstock. Technical and environmental limitations exist in using this biomass for combustion, due to the presence of harmful elements. Converting biomass using integrated generation of solid fuel and biogas from biomass system (IFBB) produces a solid fuel with lower concentrations of harmful elements and a press liquid usable for biogas generation. In this study, solid fuel generation with a commercial scale IFBB unit was investigated. The concentration of harmful elements such as N, S, Cl, and K in the solid fuel was significantly reduced compared to the original biomass silage. Emissions during combustion of the solid fuel briquettes were below German legal thresholds. Elemental concentration of solid fuel obtained from commercial scale process had a significant improvement in removal rate of harmful elements than the prototype. Hence, the limitations of using semi-natural grassland biomass as an energy source were overcome. The commercial scale IFBB plant could be used in practice to handle large volumes of green residual biomass by converting it into a solid fuel with favorable fuel properties. Full article
