Special Issue Information

Dear Colleagues,

Biomass is the most abundant renewable resource, and refers to the mass of living organisms, including plants, animals and microorganisms. It has a biochemical composition, including cellulose, lignin, sugars, fats, proteins, etc. It is estimated that 200 billion tonnes of CO2 are converted to biomass annually, and 60% by higher plants. In this context, plant-based feedstocks are considered as promising resources in achieving the goal of sustainable global carbon economy. As a result, the annual global generation of biomass waste has been threateningly increasing, which contributes to severe issues in appropriate waste conversion and utilization.

Biomass waste comes from a wide array of sources that include: agricultural residues, forestry residues, agro-industrial wastes, animal waste, municipal solid wastes and sewage, etc. The heterogeneity and crystallinity of lignocellulose in biomass waste have restricted the treatment approaches for their extensive application. Presently, the conversion of these biomass wastes into clean energy or value-added products using a variety of technologies has been deemed as a suitable approach for environmental benefits and sustainable development.

The utilization of biomass waste not only contributes to reducing pollution, but also provides an alternative way to generate bio-energy and environmental friendly products. This Special Issue aims to attract works of scientific interest to promote the conversion and utilization of biomass waste.

Therefore, we encourage you to submit articles covering the following issues:

Sustainable utilization of biomass waste.

Conversion of biomass waste into clean energy or environmental friendly products.

Bioprocessing techniques for the valorization of biomass wastes.

Sustainable aspects of biomass wastes management.

Techno-economic aspects towards sustainable biomass waste utilization.

Ecological or environmental benefit of the biomass waste utilization.

This study presented the investigation on indirect Cr (VI) bioreduction process by anaerobic sludge produced from kitchen waste (ASKW) using an external source of glucose and sulfate to favor the reducing environment. These compounds were added at the beginning of the experiment along with 500 mg·L−1 Cr (VI). The system containing 1 g of glucose and 2 g of sulfate attained a higher reduction, which was 10% higher than that of the control experiment. This study indicated that a neutral environment (pH ~7), along with a high release of polysaccharides (PS), improved the removal efficiency by Cr (VI) bioreduction process. Desulfovibrio and Sulfurospirillum (genus level), which accounted for 3% and 1% of the whole microorganism, respectively, were responsible for the sulfidogenic reaction. Additionally, Thermovirga (genus level) reduced from 14% to 11% and 10%. These microorganisms contributed to dominating the indirect Cr (VI) bioreduction process. SEM and FTIR analysis of the sludges obtaining from the indirect Cr (VI) bioreduction systems indicated that the external glucose could facilitate the formation of looser porous structures and richer functional groups of sludges, thus adsorbing more Cr (III) to reduce its toxicity. Meanwhile, the intensity of the hydroxyl bond, which possesses strong reducibility, was much higher after adding external glucose. Chromate reductase gene (chrR) and sulfite reductase gene (dsrA) contributed to the indirect Cr (VI) bioreduction process. These might be the main mechanisms of the external glucose acting on indirect Cr (VI) bioreduction by ASKW. Full article
