Municipal solid waste [MSW] has gained prominence in recent years as the rate of its generation has increased significantly. The serious problem of MSW management exists in almost all regions of India. This study aims to generate energy from MSW by selecting a suitable MSWM technology with the help...

The primary aim of this research is to identify the best anaerobic digestion process yield for generating biogas from mixed food waste in the combination of cow manure. For the biogas generation experiment, certain biodegradable domestic organic wastes gathered from restaurants, waste storage...

Anaerobic digestion of piggery wastewater mediated with biochar was investigated by COD removal rate, methane yield, process stability and microbial community analysis. The results showed that biochar could effectively improve the COD removal rate and methane yield. Compared with blank group, COD...

ABSTRACT Plastic pollution is increasing and plastic waste usually ends in environment. Microplastics (MP) as insoluble and anthropogenic micropollutant is ubiquitous and its concentration is expected to increase in the environment. One of important sources are wastewater treatment plants, where...

With the rising interest for sustainable power source and ecological security, anaerobic digestion of biogas technology has attracted considerable attention within the scientific researchers. This paper proposes a new research achievement on biogas production from Rice Mill Wastewater (RMW) with the...

The aim of this work was the application and evaluation of a mathematical model for the simulation of anaerobic hydrolysis and acid production processes. For the description of the processes involved, the Anaerobic Digestion Model ADM1 was employed. The ADM1 implementation in prefermenters is...

With increased contribution of household and kitchen wastes in overall MSW and its preferred conversion by biomethanation there is a need to study decomposition rates and kinetics, ‘leachate potential’ and related issues– especially to promote decentralized treatment. Anaerobic digestion...

The main effects of ultrasonic sludge are solubilization and release of organic components and biodegradability enhance of sludge by disrupting the physical, chemical and biological properties sludge. The objective of the current study was to determine the effect of ultrasound on anaerobic digestion...

Biogas production through anaerobic co-digestion of a mixture of cattle manure and citrus waste using an experimental facility for testing the biochemical methane potential (BMP) was investigated. No buffer solution is added to the mixture in order to use the buffer capacity from cattle manure...

A comparative economic and life cycle based analysis of five management scenarios for the solid waste generated in the island of Syros was conducted. The LCA part was performed with the LCA – IWM software. The four on-site waste management scenarios were: i) source separation of recyclable materials...

In this work, we performed a detailed full cost accounting for 7 types of existing and planned municipal solid waste management facilities (sanitary landfills, anaerobic digestion, biodrying, incineration, aerobic mechanical and biological, material recovery and waste transfer stations) in Greece...

This work focused on glycerol exploitation for biogas and hydrogen production. Anaerobic digestion of pure glycerol was studied in a continuous stirred tank reactor (CSTR), operated under mesophilic conditions (35oC) at various organic loading rates. The overall operation of the reactor showed that...

The aim of this study was to assess the feasibility of co-digesting lipids originated from domestic wastewater along with sewage sludge. Three lab-scale single stage mesophilic anaerobic digesters were operated under a constant hydraulic retention time (15 days). One system (C) was fed on a daily...

The present study has successfully explored the use of pomegranate seed de-oiled cake as a major additive and micronutrients solution as a minor additive to enhance production of biogas and enrich its methane content, using mango peel as the initial substrate. While micronutrients solution has...

Anaerobic digestion of pressmud diluted with water for biohydrogen production was performed in continuous fed UASB bio reactor for 120 days. Experiment was conducted at a dilution ratio of 1:7.5, by maintaining constant HRT of 30 hrs and the volume of biohydrogen evolved daily was monitored. Various...

Wastewaters from fossil fuel refining, pharmaceuticals, and pesticides are the main sources of phenolic compounds. Those with more complex structures are often more toxic than the simple phenol, and yet little is known about the treatment of wastewater containing a mixture of phenolic pollutants....

Anaerobic digesters often exhibit significant stability problems, that may be avoided only through appropriate control strategies. Such strategies require, in general, the development of appropriate mathematical models, which adequately portray the key processes that take place. This paper reviews...

Analysis and simulation of the behaviour of gas turbines for power generation using different nonconventional fuels obtained from different renewable sources are presented. Three biomass-tobiofuel processes are considered: anaerobic digestion of biomass (biogas), biomass gasification (synthesis gas)...

In recent years many researchers show a high interest in co-digestion, simultaneous anaerobic decomposition of a homogenous mixture of at least two biodegradable waste. Anaerobic codigestion is reported to offer several benefits over digestion of separate materials, such as increased cost-efficiency...

An Upflow Anaerobic Sludge Bed (UASB) reactor was used to evaluate mesophilic anaerobic treatment of a pre-acidified fruit wastewater. The system was operated at increasing volumetric loading rates by sequentially increasing wastewater flowrate. The operational temperature was maintained initially...
