“…At the same time, shifting food crops to cash crops becomes doubtful when the country loses self-sufficiency in food production [137], associated with increased food prices [138]. The study shows that in the case of Tamilnadu state, a significant amount of land has been distributed in the rural sector that comes under the national biofuel policy [139] to produce energy and wipe out poverty [140]. Some districts like Coimbatore and Thiruvannamalai in Tamilnadu show over-exploitation of groundwater resources for oilseed production, where production of other crops becomes minimized [141].…”

This article seeks to provide an improved and more comprehensive understanding of the concept and theories on wasteland. It achieves this by focusing on the Indian context, allowing us to unpack the importance of including multiple perspectives of wasteland narratives; this means including more positive narratives of the potential of wasteland to inform and improve prospects for land policies in the Global South. Wasteland is commonly recognized as an underutilized category of land that may transform into a valuable resource base with proper management measures. The term waste has multiple angles that carry different notions ranging from fallow to agroforestry land in the Global South and brownfield to green space in the Global North. We conduct a narrative review approach to qualitatively analyze the concept of wastelands, which has been studied in the pre-existing literature from 1970 to the present. This unsystematic literature review approach incorporates multiple elements of wasteland discourse, like understanding the meaning of the term on a global scale, setting out the meaning of the term waste into multiple perspectives explicitly in the Indian context, along with different classes and management approaches to wasteland from a national perspective. The multiple perspectives of wasteland not only generate misconceptions of land resources but spawn difficulties in land-use policy, particularly for the Indian scenario. For sustainable land-use policy, reclaiming wasteland would be the best possible way for India and other countries in the Global South, which requires a comprehensive methodological overview on wasteland narrative.

“…Second‐generation (2G) ethanol is produced from lignocellulosic agro‐residues by utilizing the various components of biomass and their intermediates. A global effort is underway to develop lignocellulosic 2G ethanol from crop residues such as sugarcane bagasse, rice straw, corn stover, and wheat straw 1,2 . However, the agro‐residue requires appropriate pretreatment for maximizing the cellulose accessibility, hemicellulose solubilization, and lignin removal, before fermentation–distillation.…”

BACKGROUND The production of second‐generation (2G) ethanol from lignocellulosic biomass generates large quantities of high‐strength complex wastewaters from various stages of the process. An effective pretreatment is necessary in order to overcome the low biodegradability of these wastewaters for further biomethane recovery. The present study reports the effect of ozonation on the biodegradability enhancement and biomethanation potential of complex 2G ethanol pretreatment process wastewaters, from acid (H2SO4) and alkali (NaOH) pretreatment process. RESULTS Ozonation (9.33 g m−3) was performed for both acid and alkali pretreatment wastewaters at a flow rate of 10 L min−1 for 1 h. Ozonation of both wastewaters increased biodegradability index (BI) up to 36% along with minimal chemical oxygen demand (COD; 7 ± 3%), color (10 ± 4%), and toxicity (22.5 ± 7.5%) reduction. Biomethane potential tests were carried out for the control and ozonated wastewaters having BI > 0.4. The acid‐pretreatment wastewater indicated poor biomethanation potential due to high presence of sulfates (COD/SO4 ~ 3.0). However, ozonation of alkali‐pretreatment wastewater facilitated up to twofold enhancement in the cumulative methane volume, while the enhancement in the rate of methane production was found to be up to 47%. Fourier transform infrared spectroscopic analysis of control and ozonated wastewaters revealed the breakdown of complex organic molecules and aromatics to readily biodegradable intermediates. The kinetics of methane generation could be predicted by the modified Gompertz model. CONCLUSION The study demonstrated the efficacy of ozonation as an effective pretreatment option to facilitate biodegradability enhancement of 2G ethanol pretreatment process wastewaters. The enhancement in biodegradability was observed to enable subsequent biogas recovery via anaerobic digestion along with COD removal. © 2023 Society of Chemical Industry (SCI).
