Hydrothermal liquefaction wastewater from sewage sludge (sludge HTLWW) is an emerging waste stream that requires treatment before being discharged into the environment. Biological treatment of sludge HTLWW is an attractive option due to the low cost and operational flexibility. In this study, we investigated and compared the performance of three ba...

Globally, nations are trying to address environmental issues such as global warming and climate change, along with the burden of declining fossil fuel reserves. Furthermore, countries aim to reach zero carbon emissions within the existing and rising global energy crisis. Therefore, bio-based alternative sustainable feedstocks are being explored for...

Current food and feed production practices via agricultural processes generate waste streams often rich in nitrogen. Conversion of the nitrogen in agricultural waste into valuable products would prevent environmental pollution and promote a circular economy. Nitrogen in agricultural waste could remain in both water-soluble and solid forms. While mi...

The present study investigates the performance of upflow anaerobic sludge blanket (UASB) reactor for stable H production from starchy wastewater supplemented with groundnut de-oiled cake using mixed consortia. Insufficient reports are available on H production for UASB reactor. Operation of the UASB reactor was divided into two stages i.e., start-u...

Developing an efficient photobioreactor (PBR) and reducing freshwater dependence are among the significant challenges for generating 3rd generation biomass feedstock. Addressing these, the present study focused on developing a modified airlift (MoAL) PBR. Its performance was further evaluated and compared with the traditional airlift PBR by cultiva...

Several edible and non-edible oil sources are currently being developed as renewable basestocks for biolubricant production. However, these feedstocks possess undesirable physicochemical properties limiting their lubricant applications. Chemical modification and additive-based routes could be used to modify their properties -suitable for different...

Whole-cell microalgae biomass and their specific metabolites are excellent sources of renewable and alternative feedstock for various products. In most cases, the content and quality of whole-cell biomass or specific microalgal metabolites could be produced by both fresh and marine microalgae strains. However, a large water footprint for freshwater...

Biohydrogen is considered a fuel for the future due to its unique attributes in clean energy generation, waste management, and high energy content. Recently, its economic production has gained considerable attention from numerous scientists and industrialists. This chapter addresses microbiological, biochemical, molecular biological, and other pers...

Aquafeed accounts for at least 75–90% of aquaculture’s operating costs. Traditional aquafeed ingredients such as fishmeal, fish oil, and soybean meal are unsustainable; further, their increasing cost necessities developing alternative feed ingredients. Microalgae-based aquafeed is not only environmentally friendly, but it can also be cost-effective...

An increase in fish consumption, combined with a decrease in wild fish harvest, is driving the aquaculture industry at rapid pace. Today, farmed seafood accounts for about half of all global seafood demand for human consumption. As the aquaculture industry continues to grow, so does the market for aquafeed. Currently, some of the feed ingredients a...

Microalgae harvesting is the crucial step in algal biofuel production, which accounts 20-30% of the total production cost. The present study investigates the potentiality of anaerobic sludge-driven extracellular polymeric substance (EPS) as a bioflocculant. Five different methods, including physical and chemical, have been employed for EPS extracti...

Acetone-butanol-ethanol (ABE) fermentation guarantees a sustainable route for biohydrogen and biobutanol production. This research work is committed towards the enhancement of biohydrogen and biobutanol production by single and multi-parameter optimization for the improvement of substrate energy recovery using C. saccharoperbutylacetonicum. Single...

The present study investigates the effect of thermal pretreated organic waste as a feedstock for the dark fermentative hydrogen (H2) production. Acidogenic mixed consortia was used for H2 production from starchy wastewater supplemented with groundnut de-oiled cake (GDOC). Physicochemical changes in GDOC after pretreatment were analyzed by using SEM...

Enormous fossil fuel depletion and drastic climate change associated with energy crisis needs to search for sustainable, renewable and environmental friendly green energy sources. Recently, microalgal biomass based feedstock has been considered as viable alternative biofuel. Higher amount of water usage and costly nutrients are the main drawback of...

Depletion of fossil fuels and climate change impels to search for sustainable and environmental friendly energy sources. Recently, microalgal feedstock has been considered as viable alternative energy source. However, the biofuel production from microalgae is still not economically viable due to high water usage and cost of the nutrients required f...

Biohydrogen production via dark fermentation exhibits great promise among the different renewable energy technologies to replace fossil fuels because it is sustainable, can be operated at ambient temperature and atmospheric pressure and is also environment friendly. In the present study, dark fermentative hydrogen production using anaerobic mixed c...

The present study investigates the improvement of dark fermentative H 2 production from organic wastes using acidogenic mixed consortia. A preliminary study was conducted to find out the suitability of the wastes as a feedstock for H 2 production using acidogenic mixed consortia, which was developed by heat-shock pretreatment of anaerobically diges...
