Theoretical and unused potential for residual biomasses in the Emilia Romagna Region (Italy) through a revised and portable framework for their categorization

Fermentation as a Strategy for Bio-Transforming Waste into Resources: Lactic Acid Production from Agri-Food Residues

“…Based on the analyses carried out and the results obtained, it could be evidenced the promising potential of the some agri-food waste, used as single or mixed sources. As reported in literature, for PPR, the prompt fermentable fructose represents more than 75% of the TC [32], whereas TP is constituted for about 22% by pectin (as galacturonic acid) [38] and PP of about 75% by starch [5]. In RCW and MW TC fraction is made up by the sole lactose [39].…”

“…In the present work, the production of optically pure L-LA by a strain of homofermentative L. casei from agri-food waste, without any other nutrients integration and without medium sterilization, has been studied. Organic waste, including milk whey, ricotta cheese whey, pear processing residues, potato pomace, tomato pomace, have been chosen based on the local availability [32], and tested as single and mixed substrates. Microaerophilic batch fermentations have been carried out at small-test level (working volume, 100 mL) in order to verify the absence of toxic compounds in waste, and then scaled-up in a 1 L fermenter (working volume, 700 mL) where the fermentation conditions were preliminary optimized.…”

Towards local bioeconomy: A stepwise framework for high-resolution spatial quantification of forestry residues

“…• A complex approach that is not easily replicable and uses specialized processed products like annual harvest maps and forest attribute maps which might not be available for other regions. [4,30] The approach used in these studies uses the forest raster data in conjunction with statistics on NAI and BEF, through a certain combination of logically defined equations. This method is further detailed in section 3.4.…”

“…An essential consideration in biomass resource assessment is the type of biomass potential being estimated. The BEE method [31], as well as several other studies, e.g., by Hamelin et al [4], and Greggio et al [30], distinguish five types of biomass potentials, i.e., theoretical potential, technical potential, economic potential, implementation potential, and sustainable potential. The type of biomass potential being assessed largely determines the approach, methodology, and data requirement [31,33].…”

Sustainable energy

“…. The study presented in [9] provides a comprehensive and exportable categorisation of the residual biomasses from different supply sectors. Thanks to the individual descriptive and quantitative parameters introduced in the paper, an estimate of the theoretical and techno-economic potential is presented for a well-industrialised, agricultural-oriented and environmentally advanced European Region.…”
