Waste streams such as municipal wastewater and animal manure contain organic materials and nutrients that can be converted and recovered for bioenergy and renewable fertilizer production. In the first part of this thesis, the anaerobic co-digestion of dairy manure with kitchen waste and chicken fat was studied for the purpose of increasing biogas production. The methane yields of co-digestion s...

Anaerobic digestion of biomasses originates different products, the most abundant of which are methane and carbon dioxide. During this process, a 60-70% organic matter reduction occurs and the final product, the digestate, is characterized by high biological stability and high contents of recalcitrant organic molecules and nutrients. In the present work digestates obtained by different mixture ...

The biochemical methane potentials for typical fruit and vegetable waste (FVW) and food waste (FW) from a northern China city were investigated, which were 0.30, 0.56 m3 CH4/kgVS (volatile solids) with biodegradabilities of 59.3% and 83.6%, respectively. Individual anaerobic digestion testes of FVW and FW we re conducted at the organic loading rate (OLR) of 3 k g VS/(m3.day) using a lab-scale c...

Purpose: In face of the need for sustainable solutions in the field of food waste management, the use of food waste disposal units (FWDs) and the anaerobic co-digestion of food waste with sewage sludge have recently been attracting more attention as an alternative to landfill. Methods: In this study a sustainability framework was developed in order to aid decision making in food waste managemen...

The objective of this study was to explore the influence different particle concentrations (0.5%–3.0 %, w/v), microfluidization pressures (0–150 MPa) and heating temperatures (30–70 °C) on physicochemical stability, microstructure, in vitro digestion ?-carotene loaded Pickering emulsions stabilized by curcumin complex nanoparticles. optimum parameters for fabrication stable were 2.0 % (w/v) con...

The potential of co-digestion mixing thickened secondary sludge (TS) from extended aeration wastewater treatment plant and locally available substrates (whey, grease septage) has been studied in this work, using three steps. first step was a batch test to determine the biological methane (BMP) different mixtures co-substrates with TS. second carried out lab-scale reactors (20 L), simulating ana...

In the present experimental study, anaerobic co-digestion of wheat straw with textile industry wastewater (TIWW) was evaluated for biogas production. Anaerobic digestion systems were operated at ambient temperature (28-30 ºC) 20 days. Five different ratios distilled water added to inoculated cow dung operating in five digesters. Time-rate derivative models, including Gompertz’s model and its re...
