“…As mentioned earlier, the need for further technological developments is one of the barriers faced by the bioeconomy, particularly the efficient and feasible conversion of biowastes into valuable bio-based products. In this regard, while certain processes exhibit industrial applicability (TRL 7-9), many processes are still at the pilot stage (TRL 4-6) or even at the laboratory level (TRL 1-3) [100][101][102].…”

The development of a resilient and circular bio-based economy is of paramount importance, notably in the EU, where current climate policies and evolving regulations strongly demand more sustainable practices, impacting monitoring and reporting, as well as the deployment of novel valorization routes for byproducts and waste streams. In this context, with the aim of assessing the current state of the European bio-based economy, a comprehensive analysis based on socio-environmental, socioeconomic, and technical indicators was carried out on major sectors, namely textiles, woodworking, pulp and paper, bio-based chemicals and materials, liquid biofuels, and bio-based electricity. Each sector was evaluated with respect to its main biological raw materials, and a methodology is proposed to link their geographical origin (inside or outside the EU), import shares, and internal production with socio-environmental impacts, based on official databases and indexes. Socioeconomic data (turnover and employment) and technical data (average bio-based content within the main products of the sector) were also considered for the analyses, allowing a multi-angle comparison between sectors and the identification of barriers and opportunities for future developments. Finally, a quantitative and qualitative overview of non-hazardous biogenic waste streams generated in the EU is presented, and opportunities for their valorization and reintegration into the EU bio-based economy are discussed. As a result of this analysis, beyond enabling the assessment of each sector within the bio-based economy, along with the assignment of values for comparison, the implementation of this evaluation facilitated the identification of improvement pathways, which were consolidated into a set of proposals.

“…The increasing pressure from governmental agencies to avoid food waste and the environmental impact of agro-industrial residues have encouraged the scientific community to investigate different strategies for managing and valorizing those waste streams. Biorefinery has been highlighted as a relevant approach for this purpose [ 1 , 2 ]. The integration of well-established processes enhances the recovery of multiple value-added products, focusing on reuse, recycling, and valorization to recover energy.…”

“…), energy, and nutrients from multiple agro-residues have been widely studied [ 3 , 4 , 5 , 6 ]. The use of processes such as extraction, fermentation, anaerobic digestion, pyrolysis, gasification, and composting are the main processes assessed to valorize agro-industrial residues [ 1 , 7 , 8 , 9 , 10 , 11 ]. However, only recently the integration of those processes has been assessed for some agro-industrial residues applying the biorefinery concept [ 12 , 13 , 14 , 15 ].…”

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.

“…In various studies S. tuberosum periderm was utilized for animal feed but proper treatment is required before subjecting it as a fodder for non-ruminants as it contains high amount of fibres to be digested ( Akter et al, 2023 ). Despite lacking economic value, S. tuberosum periderm waste holds promise due to its significant carbohydrate content, making it an attractive feedstock to produce valuable compounds ( Almeida et al, 2023 ).…”

Polyhydroxyalkanoates are a class of biodegradable, biocompatible polymers composed of polyesters of R-hydroxyalkanoic acids and deposited intracellularly by a variety of microorganisms which have potential to serve as alternative to commercial plastic. Bioplastics are gaining attention due to sustainability, biodegradability, biocompatibility, and lower carbon footprint. Nevertheless, the commercialization of PHA is predominantly hindered by the elevated production expenses arising primarily from the use of a pure sugar substrate. Our study has established a feasible method for bioplastic formation applying Pseudomonas putida MTCC 2475 and Solanum tuberosum periderm as a carbon source. To optimize the sugar yield response surface methodology was used, which released 69.34% ± 0.25% reducing sugar. PHA production experiments were performed in hydrolysate containing media as well as commercial sugar containing mineral salt media. After 48 h of fermentation of using this sugar, a biomass concentration of 2.19 gL−1, with a PHA production of 0.60 gL−1 (28.71% ± 0.55%) was obtained which was comparatively similar with synthetic media (2.56 gL−1 cell dry weight and 29.97% ± 0.45% PHA). Furthermore, the monomers of PHA produced by hydrolysate were characterized using Gas chromatography-mass spectrometry, Fourier transform infrared spectroscopy, differential scanning calorimetry, and nuclear magnetic resonance. This investigation has identified three distinct monomers of medium-chain PHAs, namely, methyl 3-Hydroxydodecanoate, 3-Hydroxytetradecanoate, and Hexadecanoic acid 3-Hydroxy methyl esters. Hence this study concludes a sustainable production of bioplastics from S. tuberosum periderm waste.
