Sustainable development is the projected demand of all nations at present. Only 20 percent of world’s primary energy requirement is met by renewable sources like solar and wind energy, hydropower, biomass, municipal and agri-wastes. Especially energy recovery from municipal and agri – wastes have gained importance due to two – fold reason: i. waste volume reduction, ii. energy recovery. The pre...

Pilot-scale digesters (850 L) were used to quantify CH4 and H2S production when using forage radish cover crops as a co-digestion feedstock in dairy manure-based digesters. During two trials, triplicate mixed digesters were operated in batch mode with manure-only or radish+manure (27% and 13% radish by wet weight in Trial 1 and 2, respectively). Co-digestion increased CH4 production by 11% and ...

The use of agricultural residues in anaerobic digestion (AD) for biogas production promotes environmental and socioeconomic benefits. This study aimed to evaluate the from dry coffee husks (DCH), wet (WCH), cattle manure (CM) AD. Prototypes Indian benchtop digesters with a batch feeding system supplied 100 CM, DCH, WCH mono-digestion (AMoD) 25:75 DCH:CM WCH:CM co-digestion (ACoD) were used expe...

Fast and effective protein digestion is a vital process for mass spectrometry (MS) based protein analysis. This study introduces a porous polymer membrane enzyme reactor (PPMER) coupled to nanoflow liquid chromatography-tandem MS (nLC-ESI-MS/MS) for on-line digestion and analysis of proteins. Poly (styrene-co-maleic anhydride) (PS-co-MAn) was fabricated by the breath figure method to make a por...

This study evaluated the co-digestion of domestic wastewater solids (WWS) and food waste (FW) at bench-scale for Yosemite National Park, California, which operates a 1900 m3/d treatment plant in El Portal, California. A 35-day biochemical methane potential test was performed on varying amounts FW as percentage total (WWS plus FW) volatile basis (%FW). Specific yield volumetric increased substan...

The effects of co-digesting sewage sludge (SS) and horse waste (HW), the composition HW, ratio HW:SS were studied using two semi-continuous digesters 9.5 L working volume. These operated in parallel with mono-digestion SS digester 1 (D1) co-digestion HW 2 (D2). In 2, there phases digestion (durations 40 43 weeks, respectively). first phase was 85% wheat straw (WS), 14% wood chips (WC), 1% manur...

Water hyacinth (Eichhornia crassipes), an invasive aquatic weed with large biomass production is of socio-economic and environmental concern in fresh water bodies such as the Lake Victoria East Africa. Efforts towards its control removal can be complemented by biogas for use energy source. The co-digestion (WH) ruminal slaughterhouse waste (RSW) has potential to improve from WH through collatio...
