“…The parameters of the substrates discussed above are correlated with the findings for biogas and biomethane yields (Table 2). With the exception of the inoculum (pH=7.47), the substrates have pH values in the acidic range (from 3.35 to 5.35), which is in agreement with other reports (Di Maria et al, 2015;Silvestre et al, 2014). Such pH values are caused by the presence of appropriate chemical compounds (organic acids, vitamins), as well as additives used in industrial food production processes (for instance, texture improvers).…”

“…It was also found that the post-digestion pulp of maize silage and liquid manure (inoculum), is the right one in carrying out anaerobic digestion of vegetable dumplings waste (VDW). Di Maria et al (2015) also carried out their experiments in stable (neutral) pH conditions, successfully carrying out AcoD (anaerobic co-digestion) of waste-mixed sludge (WMS) with fruit and vegetable waste (FVW). In turn, Zuo et al (2013Zuo et al ( , 2015 designed and carried out continuous laboratory-scale experiments on two-stage anaerobic systems treating vegetable waste (VW).…”

“…The material typically used in studies consists of food waste from restaurants or university cafeterias (Razaviarani et al, 2013;Zeshan et al, 2015). There have been reports on experiments carried out with the use of industrial waste, such as sugar beet pulp (Montanés et al, 2014), molasses (Fang et al, 2011), cheese whey (Comino et al, 2012), coffee waste (Neves et al, 2006), fat (Silvestre et al, 2014), fruit and vegetable waste (VW) (Di Maria et al, 2015). This paper is intended to analyse the biogas and methane yield of waste originating from the production of vegetable dumplings (VDW).…”

A b s t r a c t. This paper provides the analysis of results of biogas and methane yield for vegetable dumplings waste: dough with fat, vegetable waste, and sludge from the clarifier. Anaerobic digestion of food waste used in the experiments was stable after combining the substrates with a digested pulp composed of maize silage and liquid manure (as inoculum), at suitable ratios. The study was carried out in a laboratory scale using anaerobic batch reactors, at controlled (mesophilic) temperature and pH conditions. The authors present the chemical reactions accompanying biodegradation of the substrates and indicate the chemical compounds which may lead to acidification during the anaerobic digestion. An anaerobic digestion process carried out with the use of a dough-and-fat mixture provided the highest biogas and methane yields.

“…La producción de biogás a partir de desechos vegetales inoculados con líquido ruminal es una opción en las ciudades, porque los desechos o desperdicios vegetales que se generan con base en la creciente demanda de alimentos de la población tienen que conducir al desarrollo de una "cadena de uso" (Losada et al 1998). Los desperdicios de BOV, BOB, HZM y OF que se generan en grandes mercados de alimentos se pueden usar para producir CH4 por digestión anaerobia (di Maria et al 2015, Yan et al 2017. De acuerdo con Eriksson et al (2015), la digestión anaerobia tiene gran potencial para reducir la emisión de GEI al capturar los gases generados y quemarlos; pero es necesario encontrar la opción más favorable entre las que se emplean para el manejo de desechos (vertederos, composteo, incineración y alimentación animal), de acuerdo con las propiedades de cada alimento.…”

“…La digestión anaerobia es una tecnología disponible para producir energía renovable, reducir las emisiones de gases de efecto invernadero (GEI), generar energía a partir de recursos renovables e incrementar la eficiencia energética a partir de sustratos de bajo costo, como son desperdicios de frutas y vegetales (di Maria et al 2015, Li et al 2016, Yan et al 2017. El manejo adecuado de desperdicios y residuos vegetales puede generar sistemas productivos integradores (Zebeck et al 2015) y mejorar las condiciones ambientales al capturar este biogás y usarlo como sustituto de combustibles fósiles (Cioabla et al 2013, FAO 2015.…”

Palabras clave: metano, desechos orgánicos, producción de gas, bioenergía, residuos vegetales RESUMEN La creciente demanda de alimentos en áreas urbanas genera cada vez mayor cantidad de desperdicios orgánicos, incluyendo residuos vegetales. El manejo de estos residuos vegetales causa emisiones de gases efecto invernadero (GEI) por su recolección, transporte, y depósito en vertederos. Para identificar su potencial de GEI, en un mercado de alimentos se recolectaron residuos de hojas de lechuga (LS), de col (BOV), de coliflor (BOB), de maíz (HZM), de espinaca (SO) y de nopal (OF), se fermentaron in vitro usando líquido ruminal como inóculo y se compararon con heno de avena (AS), heno de alfalfa (AH) y ensilado de maíz (EZM), forrajes utilizados con frecuencia en la alimentación de rumiantes. Las variables fueron degradación in vitro de la materia seca (DIVMS), pH, cinética de producción de gas y concentración de metano (CH4). La fermentación se realizó durante 96 h a 39 ºC y las muestras de gas para medir la concentración de CH4 se tomaron a 9, 12, 24, 34 y 48 h de incubación. La DIVMS de LS, BOV, BOB, HZM y OF fue 12.8 % mayor a AS, AH y EZM. Entre las 9 y 12 h de incubación la emisión de CH4 a partir de BOV, BOB and HZM fue 44.8 % superior a los tres forrajes. La principal conclusión es que estos residuos vegetales son degradados adecuadamente por los microorganismos ruminales y, por lo tanto, se pueden usar para la producción de biogás en áreas urbanas para disminuir su depósito en vertederos.Key words: methane, organic wastes, gas production, bioenergy, vegetable residues ABSTRACTThe growing demand for food in urban areas generates an increasing amount of organic wastes, including vegetable residues. The management of these wastes can lead to greenhouse gases emissions (GHG) through its process, including collection, transportation, Rev. Int.

The Food–Materials Nexus: Next Generation Bioplastics and Advanced Materials from Agri‐Food Residues

The most recent strategies available for upcycling agri‐food losses and waste (FLW) into functional bioplastics and advanced materials are reviewed and the valorization of food residuals are put in perspective, adding to the water–food–energy nexus. Low value or underutilized biomass, biocolloids, water‐soluble biopolymers, polymerizable monomers, and nutrients are introduced as feasible building blocks for biotechnological conversion into bioplastics. The latter are demonstrated for their incorporation in multifunctional packaging, biomedical devices, sensors, actuators, and energy conversion and storage devices, contributing to the valorization efforts within the future circular bioeconomy. Strategies are introduced to effectively synthesize, deconstruct and reassemble or engineer FLW‐derived monomeric, polymeric, and colloidal building blocks. Multifunctional bioplastics are introduced considering the structural, chemical, physical as well as the accessibility of FLW precursors. Processing techniques are analyzed within the fields of polymer chemistry and physics. The prospects of FLW streams and biomass surplus, considering their availability, interactions with water and thermal stability, are critically discussed in a near‐future scenario that is expected to lead to next‐generation bioplastics and advanced materials.
