“…The projects with extraction processes defined a lifetime of 10 years, while 20 years were specified for projects with anaerobic digestion processes. The interest rate ranged from 5.5 to 25% [ 98 , 155 , 157 ]. Except for the wet anaerobic co-digestion, all the processes were revealed to be economically viable.…”

“…The extraction of lycopene and carotenoids leads to high revenues (111–10,300 kUSD/y) due to the high value of those compounds. Hatami and Ciftci [ 155 ] and Yadav et al [ 157 ] reported very high prices for tomato extracts (423 USD/kg and 13,050 USD/kg, respectively), explaining the revenues reported ( Table 7 ). A sensitivity analysis for the supercritical fluid extraction proposed by Hatami and Ciftci [ 155 ] revealed that extract price had the most significant impact on the NPV [ 158 ].…”

The tomato industry is a relevant socio-economic activity in the European Union, while it generates a large variety of residues. Tomatoes unfit for consumption, tomato peels, seeds, industrial pomace, and plants are examples of residues of this industry. Commonly, some of the residues can be left in the field, composted, used for animal feeding, or valorized through anaerobic digestion. However, more economic value can be attributed to these residues if a biorefinery approach is applied. Indeed, many value-added compounds can be obtained by the integration of different processes while closing the carbon and nutrient loops. The extraction of bioactive compounds followed by anaerobic digestion and composting seems to be a viable proposal for a biorefinery approach. Thus, this study aims to review the biorefinery strategies for valorizing tomato residues, highlighting the main processes proposed. The recovery of lycopene, β-carotene, and phenolic compounds has been widely studied at the lab scale, while energy recovery has already been applied at the industrial scale. Although techno-economic analysis is scarce for tomato residue valorization processes, positive net present values (NPV) and low payback times (PBT) have been reported in the literature. Thus, more work comparing multiple extraction technologies and biorefinery strategies coupled with economic and environmental assessment should be performed to select the most promising management route for tomato residues.
