“…used residues of açaí, cocoa, coconut, cupuaçu and Brazil nut to evaluate the combustion properties and create renewable energy alternatives for the industry of the Amazon region of Brazil. Similarly, residues of species such as tomato, squash, carrot, and potato were used for the treatment of plant solid waste and the development of scientific knowledge on the kinetics of hydrolysis in anaerobic codigestion systems (Leite et al, 2021).…”

Several plant residues can be generated during the stages of industrial processing, such as fruit peel, seeds and bagasse, and these can give rise to high-value products. The management and use of this waste is of global interest. The aim of this study was to evaluate the spatio-temporal evolution of scientific knowledge on the reuse of agroindustrial waste generated in Brazil through a scientometric analysis. To this end, a search was performed in the databases Scopus, Scielo, and Web of Science between the years 1991and 2021. The words used as indexers were agribusiness waste, vegetable waste, fruit waste, biomass waste, plant residue, and chemical characterization. The following selection criteria were adopted: search of indexers by title, scientific articles, articles in English and Portuguese, and articles on plant waste generated in Brazil. There was an increase in publications over the years, with a greater number of studies (21.46%) in the chemistry area, addressing mainly the physical-chemical characterization of materials. In Brazil, sugarcane (Saccharum officinarum L.) was the most studied species with a view to reusing its residues. We identified species from highly threatened Brazilian biomes, such as the Atlantic Forest and Cerrado, with the potential for transformation into new materials. The gaps in knowledge, evidenced in this analysis, suggest that more studies should be carried out on residues of native plant species which impact local communities. In particular, studies could focus on applicability in health and cosmetics, which are promising areas for plant materials and still little investigated.

“…The choice of VSW was motivated by the large amount of this residue that is generated in Latin America, approximately 30% of all runoff of vegetables and fruits [23,24]. In addition, the combination of VSW and ASS results in a promising anaerobic co-digestion process for biogas generation and is approached with reoccurrence [25][26][27]. The influence of substrate particle size and total solids concentration on the kinetic behavior of this process was also investigated, in order to explain the effects of these parameters on the latency phase time, the maximum volume of biogas produced, the maximum generation rate of biogas and the hydrolysis constant.…”

The present study investigated the kinetic modeling of anaerobic co-digestion under the optics of Modified Gompertz, Function transfer, Logistic function, Modified first order, and Cone models. As substrate, vegetables and fruits solid waste (VSW) and anaerobic sewage sludge (ASS) were used. The synergistic effects of substrate particle size (SPS) and total solids (TS) concentration were investigated. With the application of the Akaike information criterion (AIC) and the NRMSE it was possible to determine the performance order of performance of the models: Logistic function > Cone > Modified 1st order > Modified Gompertz > Function transfer. The biogas production and kinetic parameters predicted by Logistic function model reached the maximum likelihood in relation to the experimental result (AIC 36; NRMSE 43.292). SPS had a statistic significant effect on the cumulative biogas (Mmax) yield and on the hydrolysis constant (K’’hyd). In turn, the TS concentration influenced the latency phase time (λ) and the maximum rate of biogas production (Rmax).
