Biomass-to-sustainable biohydrogen: Insights into the production routes, and technical challenges

Comparative Techno-Economic and Life Cycle Analyses of Synthetic ‘Drop-In’ Fuel Production from UK Wet Biomass

“…Also, dropin fuel via HTL can easily be integrated into existing infrastructures than other wet biomass technologies like AD [27,28]. However, like other thermochemical processes, it can be affected by issues such as tar formation and catalyst poison [29][30][31][32]. HTL technology is yet to be commercialised, as such the technical and economic parameters of the technology are yet to be fully understood with certainty.…”

CO2 Capture from Flue Gas on a Pilot Scale Using Porous Carbon Prepared from Cotton Stalk Crop Residues through an Industrially Viable Activation Process

“…Through activation techniques, physical or chemical, the PC can be produced effortlessly. In addition to addressing waste management issues, this transformation provides a cutting-edge method for repurposing agricultural waste into a useful resource for uses like CO 2 capture and environmental sustainability …”

“…While their processing procedures may include energy-intensive and environmentally hazardous techniques, their sourcing may contribute to deforestation, habitat loss, and environmental deterioration. On the other hand, PC prepared from crop wastes presents an appealing solution for CO 2 capture. , Crop residues, in contrast to conventional sources, are plentiful, renewable, and frequently seen as waste, making their conversion into PC both economically feasible and environmentally benign . This method contributes to sustainable carbon capture tactics while addressing concerns regarding agricultural waste management.…”

“…20,21 Crop residues, in contrast to conventional sources, are plentiful, renewable, and frequently seen as waste, making their conversion into PC both economically feasible and environmentally benign. 22 This method contributes to sustainable carbon capture tactics while addressing concerns regarding agricultural waste management. India, an agrarian economy produces about 650 million tonnes (MT) of agricultural waste every year, with a large percentage going as animal feed, fuel, and composting.…”

“…In addition to addressing waste management issues, this transformation provides a cutting-edge method for repurposing agricultural waste into a useful resource for uses like CO 2 capture and environmental sustainability. 22 Compared with physical activation techniques, chemical activation has the potential to produce PC of superior quality. For the chemical activation of agro-residues, several chemicals have been used, 26 including NaOH, 27 37 Due to its ability to produce clearly defined pores and obtain high surface areas, KOH is the preferred reagent.…”
