Abstract Sludge biosolids for agricultural application represent a valuable fertilizer but also a health risk unless pathogens are effectively reduced, and recontamination controlled. The Post Anaerobic Digestion Thermal Hydrolysis Process (Post-AD THP) is gaining interest due to improved dewaterability, reducing the volume and thus transportation costs of biosolids. However, Post-AD THP results in

Abstract In Europe, recent regulations on advanced biofuels have prompted a search for new fuel sources and the development of synthesis methods meeting the demanding specifications of the sector. However, in developing countries such as Algeria, where a significant stock of frying oil is unused, the use of diesel engines powered with waste-oil-derived biofuels must be explored. In this work, the variables

Purpose Biomass slurries, such as those subjected to microwave-assisted alkaline (MAA) pretreatment, will become common substrates for the production of biofuels in the future. While the rheology of acid and ionic liquid pretreated biomass is known, the rheology of alkaline pretreated biomass is not yet reported; hence, the goal of this study was to establish the rheological characteristics of untreated

Abstract Lignocellulosic feedstocks are gaining increased popularity for novel industrial applications because of their availability and bio-renewability. Using lignocellulosic materials, especially from agricultural and forestry sectors could help reduce the over-dependence on petrochemical resources while providing a sustainable waste management alternative. This review aims to describe the chemistry

Abstract One strategy to re-use solid urban wastes is the production of energy by anaerobic digestion. This process also generates high volume of digestates, which are frequently disposal in landfills. The aim of this work is to assess anaerobic digestates as agricultural inputs. Three different biomethanation wastes from different plants were collected. Firstly, a complete physico-chemical characterization

Abstract Large volumes of liquid waste are generated in processing operations of seafood industry. Such effluents have high concentrations of soluble protein, but it is necessary to concentrate it for utilization. Therefore, the present study investigated the effects of the use of hydrochloric (HCl) and trichloroacetic (TCA) acids on biochemical and antioxidant properties of recovered solids from sardine

Abstract Substantial waste is generated from fish processing industries causing pollution and health hazard. Hence, synthesizing biodegradable film from myofibrillar protein dispersion of fish waste was attempted which may serve as “Wealth from Waste”- an eco-friendly initiative. Film dispersions were gamma-irradiated at a dose of 10 (D10) and 25 kGy (D25) before casting and their physical properties

Biogas is one of the practical vitality sources of energy that can be delivered from numerous sorts of biomass. Biogas production from fresh digestate bacterial crude culture; Providencia alcalifaciens and Alcaligenes aquatilis isolated from municipal wastewater treatment plants located in Port Said, Egypt and identified with 16S rRNA; amended with aquatic macrophytes; Pistia stratiotes and Potamogeton

Abstract The inadequate management of municipal solid waste can cause environmental and health issues, however the predominance of municipal biowaste and food waste make anaerobic digestion (AD) an attractive option for the treatment and recovery of organic matter. From AD two by-products with high potential use are obtained, such as methane gas (present in biogas) and the digestate, whilst the process

Abstract The recovery efficiency of waste valorization processes depends on an interplay of different conditions that are sometimes overlooked. Process optimization by the means of establishing mathematical relations between the process parameters and outputs is a strong tool to identify optimal operating conditions based on experimental data. In this study, the extraction of anthocyanins from chokeberry

Abstract Proteins were extracted from a prickly pear seed cake using the Osborne extraction method. Physico-chemical, antioxidant and functional properties of the major protein fractions (albumin and glutelin) were studied. Glutelin fraction presented good amount of proteins (60.42% dry weight) with appreciable essential amino acids content (24.45% of total amino acids). The Fourier transform-infrared

In this research, two copper-binding peptides were identified in the proteolysate of Acetes japonicus. Firstly, the examination of the effects of hydrolysis conditions including enzyme type, pH, temperature, enzyme:substrate (E:S) ratio and hydrolysis time on the copper-binding capacity (CBC) was carried out. Secondly, to optimize the hydrolysis, response surface methodology (RSM) was applied via E:S
