“…In contrast to traditional submerged fermentation, solid-state fermentation Frontiers in Chemical Engineering frontiersin.org technology has several biotechnological advantages, including low to medium cost and energy consumption, little effluent output, and decent product stability (Pandey, 2003;Holker and Lenz, 2005;Singhania et al, 2009). Therefore, producing Bt-based biopesticides from sludge or wastewater could be a novel and ingenious way to clean up the environment and an addition to the path for commercialising affordable biopesticides (Tiwari and Awasthi, 2022). Biopesticide production from the starch industry wastewater and sludge has been thoroughly studied including pretreatment, medium amelioration agents, optimising process parameters, scaleup, and formulation and development studies (Tyagi et al, 2002;Brar et al, 2004).…”

Global demand for freshwater is rapidly escalating. It is highly essential to keep pace with the necessities of the increasing population. The effluents of wastewater are gradually identified as a reservoir of resources for energy generation and economic boom. Henceforth, most wastewater and sludge have great potential for reuse and recycling. The re-utilization and valorization of wastewater and sludge contribute to accomplishing sustainable development goals, combating water scarcity, and alleviating adverse environmental impacts of wastewater on the environmental components. The present article highlights the most novel approaches for wastewater treatment for the waste valorization of different industrial origins and the generation of value-added products and recovery of biopolymers, vitamins, enzymes, dyes, pigments, and phenolic compounds. We highlighted the life cycle assessment and techno-economic analysis. In addition, we have addressed a critical overview of the barriers to the large-scale application of resource recovery strategies and economic, environmental, and social concerns associated with using waste-derived products.

During the pandemic, biomedical waste (BMW) management was reported as a global problem. World Health Organization has also stressed that COVID-19 resulted in the production of tens of thousands of tons of BMW. It includes waste from hospitals, research laboratories, pharmaceutical industry, etc., and among them, pharmaceutical waste has a major effect on the ecosystem. It includes waste generated during diagnosis, research activities, immunization, and treatment, such as vials, bottles, gloves, masks, needles, expired/unused/spilled/contaminated drugs, radioactive material, pharmacological waste, etc. Timely and precise management of BMW is a vital issue, and the present manuscript aims to provide a comprehensive overview of BMW with a major focus on pharmaceutical waste, their types, points of entry, and its management using pyrolysis, nanotechnologies, etc. Available guidelines and challenges associated with the management technologies have been reviewed, and we have proposed a practical framework suggesting the role of government agencies and the pharmaceutical industry and expected outcomes from the suggested techniques in stepwise manner. Besides various developments in the pharmaceutical field, there is requirement to develop and implement environmentally friendly approaches for BMW disposal to benefit the community.
