The rapid urbanization witnessed in developing countries Asia and Africa has led to a substantial increase municipal solid waste (MSW) generation. However, the corresponding disposal strategies, along with constraints land resources finances, compounded by unorganized public behaviour, have resulted ineffective policy implementation monitoring. This lack of systematic targeted orientation, combined blind mapping, inefficient development many areas. review examines key challenges MSW management from 2012 2022, drawing insights 171 academic papers. Rather than solely focusing on recycling, study proposes sorting at source, optimization landfill practices, thermal treatment measures, strategies capitalize value as more pertinent solutions aligned local realities. Barriers optimizing systems arise socio-economic factors, infrastructural limitations, cultural considerations. emphasizes importance integrating area into circular economy framework, focus enhancing citizen participation reduction promoting recycling initiatives, seeking economic assistance international organizations.

Biotransformation of Lignocellulosic Biomass to Value-Added Bioproducts: Insights into Bio-Saccharification Strategies and Potential Concerns

Topics in Catalysis, Год журнала: 2024, Номер unknown

Опубликована: Апрель 18, 2024

Abstract Lignocellulose is considered to be the most abundant and sustainable material on earth. The concept of lignocellulosic biomass conversion into value-added chemicals or materials gaining in importance worldwide as a means replacing conventional petrochemical resources for environmental sustainability. production biofuels such bioethanol from consists three main processes: pretreatment, enzymatic saccharification, fermentation. As lignocellulose exhibits highly recalcitrant structure, effective pretreatments are required its deconstruction, making carbohydrates accessible microbes produce valuable bioproducts. These carbohydrate polymers (cellulose hemicellulose) then transformed free monomeric sugars by process saccharification. Saccharification, especially hydrolysis, crucial step achieving bioconversion. Several strategies have been developed diminishing recalcitrance, ultimately improving efficiency product conversion, reducing overall costs. Some these approaches include consolidated bioprocessing, bio-saccharification (on site), well simultaneous saccharification fermentation, separate hydrolysis fermentation (off site). This review provides detailed overview current on-site off-site highlights key factors obtaining bioproducts feedstock via economically feasible bioconversion processes. Moreover, optimization various industrially important biomasses also summarized.

A concise review on waste biomass valorization through thermochemical conversion

Current Research in Microbial Sciences, Год журнала: 2024, Номер 6, С. 100237 - 100237

Опубликована: Янв. 1, 2024

Due to an increase in industrialization and urbanization, massive amounts of solid waste biomass are speedily accumulating our environment, which poses several adverse effects on habitat human health thus becoming a matter discussion the environmental community. With reference circular economy, continuous efforts have been put forward for setting up organised management approach combination with efficient treatment technique increasing profitable utilization waste. This review aims provide systematic recent thermochemical technologies employed converting generated from different sources into valuable products like biochar, bio-oil, heat, energy syngas. The article further focuses few important aspects conversion useful technical factors affecting processes, applications by-products conversion, biological pretreatment biomass. assists interesting scientific trends boosting valorization through low-cost, efficient, environment-friendly sustainable technologies.
