“…The following values were considered to calculate the maximum biofuel production from the investigated feedstocks: 30 and 70 % water content in AR and AFW, respectively , . 80 and 45 % total sugar content on a dry mass basis in AR and AFW, respectively , , . Biofuel yields were fixed according to the data reported in the literature , , , . …”

“…Potential exploitation of such residues as carbon sources for biorefinery processes must take into account not only the larger availability of AR (150 Mt a −1 ) compared to AFW, but also the advantages related to AFW use. In particular: Their production sites are localized at the agro‐food industrial sites. AFW is produced almost uniformly in European countries. AFW have medium to low lignin content . AFW exploitation can support the development of a circular economy. …”

“…Few data on innovative pretreatments of AR and AFW are available due to very recent progress in this kind of pretreatment, and no data are available on AFW steam explosion because of the low lignin content in this feedstock, which makes this aggressive pretreatment unnecessary .…”

“…Considering that the annual superficial productivity of M. sinensis is 20 000 kg ha −1 a −1 , the potential availability of M. sinensis in Campania is about 3460 t a −1 . The following values were considered to calculate the maximum biofuel production from the selected feedstock: 80, 45, and 75 % total sugar content on a dry basis ω i in AR, AFW, and M. sinensis , respectively , , .

“…Lately, agro‐food wastes (AFW) from industrial food processing are replacing lignocellulosic biomass, which avoids using arable lands and boosts the circular economy. Moreover, several studies have been published on innovative eco‐sustainable pretreatments, e.g., operating at low temperature and at atmospheric pressure, to produce fermentable sugars by hydrolysis of cellulosic feedstock , . Among these novel pretreatments, ionic liquids (ILs) can be used as effective solvents for lignin removal.…”

The use of agricultural residues (AR) and agro-food waste (AFW) as potential feedstocks for the production of second-generation ethanol and butanol is reviewed. The maximum biofuel production rate from AR and AFW was estimated on the basis of the feedstock availability rate, the average composition, and the biofuel yields reported in the literature. According to the estimations, the contribution of ethanol and butanol to current European biofuel accounts could be 32 and 23 % if traditional pretreatments are applied, and 40 and 19 % if they are produced by innovative pretreatments, respectively. Finally, the analysis was applied to a local scenario (Campania, Italy), with a view to potential decentralized exploitation of AR and AFW.
