The CA / NiO composites were prepared by the chemical method and electrodes were compacted into forms of self-consistent tablets, which were placed in a two-electrode cell using sulfuric acid (H2SO4) as electrolyte at 2 M. The electrochemical part was evaluated by means of Cyclic voltammetry and galvanostatic chronopotentiometry, obtaining the electrical behavior of the electrodes for their application in supercapacitors (SCS). Finally, the specific capacitance of the SCS was determined from CA / NiO, as a result it was obtained that the CA / NiO-48-700 ° C-KOH samples showed a maximum capacitance of: 405.405 F / g respectively.

In Mexico, Veracruz has an area of 7.24 x 106 hectares, representing 3.7% of the national area, being the main provider of agroindustrial products due to its diversity of ecosystems. The objective of this paper is to evaluate the bioenergy potential of organic solid waste generated from the main agroindustrial products of the state of Veracruz. To carry out this research, ten main crops of Veracruz were selected through a literature review, determining the percentage of waste generation and heating value of each of them. With the previous data, the tons of agroindustrial waste and the bioenergy potential were estimated. Finally, the total bioenergy potential of agroindustrial wastes was calculated. As part of the results, Veracruz produces approximately 25.5 x 106 tons of agroindustrial products made up of sugarcane, orange, lemon, pineapple, coffee, banana, grapefruit, watermelon, rice and pear. Derived from the ago-industrial activity, 6.97 x 106 tons of waste are generated annually, being the sugarcane waste the most with 75% equivalent to 5.28 x 106 tons, followed by citrus around 0.98 x 106 tons. Likewise, and as a consequence of agroindustrial waste, Veracruz has a bioenergy potential close to 130.00 PJ per year, which would place it as the largest supplier of renewable energy from biomass.","PeriodicalId":194964,"journal":{"name":"Renewable Energy, Biomass & Sustainability","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129758685","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the biggest problems of the 21st century is perhaps the need to provide water for the growing world population.

On the other hand, the production of ornamental plants requires multiple nutrients for their proper development, a source available in high concentrations in wastewater. Recent research on constructed wetlands (CWs) that use ornamental plants to treat wastewater and at the same time are used as a means of growth, is considered a sustainable alternative. This study evaluated the influence of light intensity on the growth and flowering of ornamental plants (Lavandula sp., Anthurium sp., Zantedeschia aethiopica and Spathiphyllum wallisii) in constructed wetlands, fed with domestic wastewater. 30 mesocosms of constructed wetlands were used as a culture medium for ornamental plants, the effect of light intensity on the development of the plants was measured, as well as the removal of Nitrogen (N-NO3), phosphate (P-PO4) and biochemical demand of oxygen (DBQ5). The plants were able to adapt and grew healthy in the three-support media with the exception of Lavandula sp., which did not survive in any of the systems, showing that in the months when the light intensity was higher, a higher growth rate was reached to 9.5 % on average. In terms of the removal of N-NO3 (45- 60%), P-PO4 (20-23%) and COD5 (60-85%), no significant differences were found between any of the substrates. The above allows us to affirm that CWs, are suitable means for cultivation of ornamental plants and the development of them is favored with intensities of light in ranges from 720 to 856 µmol · m −2 · s −1, On the other hand, the substrates used proved to be efficient to remove contaminants, but at the same time to facilitate the healthy development of the used ornamental vegetation, with the exception of the lavender sp.

Biosorption is an alternative method for the treatment of effluents contaminated with Cr (VI), which consists of using biomass as adsorbent, preferably agro-industrial wastes which, possessing functional groups on their surface and pores, are susceptible to binding with Cr (VI) through mechanisms such as complexation (Al-Homaidan et al., 2018). The nanche fruit (Byrsonima crassifolia L.) has economic importance due to its commercial production, the Agroindustrial and Fisheries Information Service (SIAP) reported in 2016 a production of 7.1 thousand tons of which 0.781 thousand tons of waste were generated considering that 11% of the fruit corresponds to the endocarp which is considered a byproduct (SIAP, 2018), according to the above; using the byproduct as a bioadsorbent develops a new route for its utilization.","PeriodicalId":194964,"journal":{"name":"Renewable Energy, Biomass & Sustainability","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124731028","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Humic substances possess a large amount of phenolic and carboxylic groups, which provide them with characteristics for crop development. These include colloidal action on clays, ion exchange capacity, chelating action for metal capture and stimulation of soil micro-fauna and -flora.

However, sustainable forest management [SFM] allows considering charcoal as a renewable source of energy (Antinori and Rausser, 2010; Camou-Guerrero, et.al., 2014; Sist, et.al., 2014; Aguirre-Calderón, 2015; FAO, 2017; Ramírez, 2017). Mexican regulations focus SFM on functionality, industrialization and large scale (Antinori and Rausser, 2010; Deschamps and Madrid, 2018; Cravioto, 2019); informality is considered unsustainable due to irregular and poor management practices (Sist, et.al., 2014; Monárrez- González, et.al., 2018). We analyzed impacts of three oak management systems on tons of BSS: [1] conservation, [2] formal production, and [3] informal production; influenced by [1] advantageous (nursery), and [2] disadvantageous (drying shed) biophysical conditions.
