1. Extraction and Characterization of Pequi Seed Oil for Biodiesel Production: A Green Management of Waste to Biofuel Using Ethanol and Heterogeneous Catalysis
This work reports the characterization of a vegetable oil extracted from pequi seeds, an agroindustrial residue, and its biodiesel production using ethanol and heterogeneous catalysis. The pequi seeds showed 40.73 wt.% of extractive content, which represents a large amount of the biomass composition. The crude oil extracted from the pequi seeds with ethanol

2. Utilization of the Corncob Agro-Industrial Residue as a Potential Adsorbent in the Biosorption of Bisphenol-A
The presence of plastic waste in water bodies has led to a growing concern due to the impact on human health. Among the most important plastic additive molecules is bisphenol-A (BPA). On the other hand, micro-pollutant removal processes that make use of agro-industrial waste have aroused the interest of researchers. This is because the accumulation of lignoc

3. ADDITION OF BOILER CHARCOAL WASTE TO COMPOST FOR USE AS SUBSTRATE FOR VEGETABLE SEEDLINGS
ABSTRACT The recovery of waste from the broiler production chain (BPC) is consistent with the principles of a circular economy. Besides turning waste into organic compost, its use as substrate for the production of vegetable seedlings further increases its economic value. However, it is necessary to adapt its characteristics to enable its use as substrate. T

4. Composition and mineralization of organic compost derived from composting of fruit and vegetable waste
ABSTRACT Fruit and vegetable waste can be used for the production of organic compost, which when mineralized can increase the availability of nitrogen. The objectives of this study were: (a) to produce compost from different ratios of fruit and vegetable waste, rice husk and poultry manure that meets the legislation on organic fertilizers and (b) to assess t

5. BIODEGRADATION OF ACACIA AND CHESTNUT TANNINS BY NATIVE ISOLATES OF THE GENUS Penicillium AND Aspergillus
Abstract In the present work, the potential of native isolates of fungi strains to biodegrade vegetable tannins used in the tanning industry was evaluated. Penicillium citrinum showed to be more efficient for consumption of acacia tannin, reaching 94.85%. Aspergillus chevalieri needs a greater adaptation phase (48 h) in both acacia and chestnut medium, evide

6. Estudo comparativo do tingimento de malha PES/CO com água tratada com resíduo de clarificação de óleo vegetal, na forma natural e calcinada
RESUMO A indústria têxtil utiliza um grande volume de água, o que torna necessário encontrar opções mais sustentáveis para o seu uso, como a reutilização em novos tingimentos. O uso de um resíduo industrial sólido, como adsorvente, poderá ser uma alternativa para tratar o efluente têxtil. Este estudo teve como objetivo testar a viabilidade do re

7. Visual quality and waste of fresh vegetables and herbs in a typical retail market in Brazil
RESUMO Devido à sua alta perecibilidade, hortaliças folhosas e ervas frescas são transportadas para o mercado logo após a colheita. É de esperar que parte dos danos sofridos durante a colheita e o transporte desses produtos resultem em perda somente nos elos seguintes da cadeia, quais sejam, varejo e consumo. O manuseio inadequado e o uso de estratégia

8. Vegetable Waste Inclusion in Broiler Diets and its Effect on Growth Performance, Blood Metabolites, Immunity, Meat Mineral Content and Lipid Oxidation Status
ABSTRACT The aim of present study was to evaluate the effect of feeding vegetable waste (VW) to broilers on their growth performance, serum chemistry, immune status, meat mineral content and lipid oxidation status. For this purpose, 100 one-day-old chicks (Cobb 500) were acquired from a commercial hatchery and allocated according to a completely randomized d

9. CHEMICAL COMPOSITION OF SWINE WASTEWATER, SOIL, AND TIFTON 85 AFTER 8 YEARS OF APPLICATION
RESUMO O objetivo deste trabalho foi avaliar a composição química da água residuária da suinocultura (ARS) e efeito nos atributos químicos do solo e planta em um experimento de longa duração. A área destina-se a 8 anos a produção de feno de capim Tifton 85 (Cynodon spp.), com aplicação média anual de 360 m3 ha-1 dividida em 6 aplicações. Tamb

10. Fast Spectrophotometric Determination of Iodine Value in Biodiesel and Vegetable Oils
Iodine value is an important quality parameter for evaluation of the oxidative stability of biodiesel and vegetable oils, but the official methods are time-consuming and demand large amounts of reagents and solvents. The present work describes a novel procedure for determination of iodine value based on the discoloration of a triiodide aqueous solution due t

11. Drying and extraction of astaxanthin from pink shrimp waste (Farfantepenaeus subtilis ): the applicability of spouted beds
Abstract In this study, the spouted bed drying technique was used to obtain powder from shrimp wastes, with high quality for subsequent extraction of astaxanthin using vegetable oil, as alternative to organic solvents. Shrimp waste paste was dried in three inlet air temperatures (70, 80 and 90 °C), and air velocity used in the experiments was 100% over min

12. Microstructure and thermal and functional properties of biodegradable films produced using zein
Abstract Research is being conducted in an attempt to produce biodegradable packaging to replace plastic products, thereby reducing solid waste disposal. In this work, zein films were produced from vegetable oils (macadamia, olive and buriti) and from pure oleic acid. The surface of zein-based films made using oleic acid has a good lipid distribution. The h
