Conventional mining of economically and strategically important critical rare earth elements (REEs) (such as neodymium, lanthanum and dysprosium), and chalcogens (such as selenium and tellurium) are associated with a huge economic and environmental cost. Therefore, the need to recover REEs as well as chalcogens from different waste streams includin...
Developing novel strategies to enhance volatile fatty acid (VFA) yield from abundant waste resources is imperative to improve the competitiveness of biobased VFAs over petrochemical-based VFAs. This study hypothesized to improve the VFA yield from food waste via three strategies, viz., pH adjustment (5 and 10), supplementation of selenium (Se) oxya...
The use of phytoremediation as a method for wastewater treatment or removal of pollutants is garnering significant interest and duckweed (DW), a free floating macrophyte, depicts significant potential for the removal of nutrients and toxic compounds from contaminated waters. The present work aimed to develop an integrated process for remediating se...
Contains abstracts from the G16 Conference organised in Galway, Ireland (November 17-18, 2022).
The energy potential of dissolved air floatation (DAF) slurry, a lipid-rich waste, is largely disregarded with the common practice of land spreading or landfilling. On the other hand, selenium (Se) contaminated wastewaters are perceived as unsuitable feedstocks because of their toxicity. This study aimed to evaluate the anaerobic co-digestion perfo...
This study investigated the potential of granular activated carbon (GAC) supplementation to enhance anaerobic degradation of dairy wastewater. Two sequential batch reactors (SBR; 0.8 L working volume), one control and another amended with granular activated carbon, were operated at 37 oC and 1.5‐1.6 m/h upflow velocity for a total of 120 days (four...
Dissolved air floatation (DAF) slurries are an unconventional substrate for anaerobic digestion owing to their high COD concentrations, mainly consisting of lipids. Batch anaerobic digestion of DAF slurry was conducted to investigate the methane production through dilution of the slurry (with mineral salt medium, MSM) and by adjusting the initial p...
The status of circular economy (CE) in Thailand is reviewed in this chapter. The current CE practices and policy instruments used towards sustainable resource management in Thailand are presented as well. CE indicators for Thailand are extensively studied and summarized in the paper. Based on the review, it is established that the existing policies...
The increasing generation of solid waste and its improper management has imposed daunting impact on Kabul city. The city of 5 million people generated 3050 tonnes of solid waste every day in 2018. Data analysis shows that if an estimated 25% waste reduction is achieved gradually by 2023, then the total cost of the system will be reduced to 1505.9 m...
A pilot scale decentralised Continuously Stirred Tank Reactor (CSTR) was designed, developed and installed, with 675 liter working volume, to treat food waste generated from the Asian Institute of Technology (AIT) campus community. The reactor was operated in mesophilic, anaerobic and wet condition with feedstock as food waste of 10 percent Total S...
Enhancement of synergistic effect by co-digestion and accelerating anaerobic reactions by thermophilic condition leads to efficient waste treatment and energy recovery. In this study, Bio-Methane Potential (BMP) test was conducted to arrive at the optimum ratio of feedstock for anaerobic co-digestion. Linear correlation of biogas yield with C/N rat...
The increased solid waste generation and its improper management have imposed daunting impacts in Kabul city. The waste audit conducted for this study shows that the city of 5 million people generates 3050 tonnes/day of municipal solid waste. Lack of source segregation practices, dumping of hazardous and C&D waste with the municipal waste are the m...
Anaerobic digestion has emerged as the preferred treatment for organic fraction of municipal solid waste. Digestate management strategies are devised not only for safe disposal but also to increase the value and marketability. Regulations and standards for digestate management are framed to address the pollution concerns, conserve vulnerable zones,...
Biogas, a byproduct of anaerobic decomposition of organic wastes, contains 50–70% methane, 30–50% carbon dioxide, traces of hydrogen sulphide, fractions of water vapour and other gases. Purification of biogas involves the removal of CO2 , H2S and water vapour from the biogas to overcome the problems like low energy density, corrosion in engines, pi...

What are some of the nitrate-reducing bacteria during anaerobic digestion of nitrate rich wastewater?
Is it possible for simultaneous reduction of Selenium during anaerobic digestion of Selenium rich waste streams?
We are interested to carry out treatment of Selenium rich plant crops like duckweed. Could you please suggest some other crops which are good at Selenium uptake?
