“…As many lack resources, and machinery and labour have limited availability, especially during peak times (Bhatt et al, 2022; Bhattacharyya et al, 2021; Dutta et al, 2022), contractors who collect and transport the straw will be needed. Indeed, most of our respondents would like a company to harvest and collect the residue instead of doing it themselves.…”

How can we build inclusive circular supply chains? Examining the case of agricultural residue usage in India

Circular economies can, at best, contribute to sustainable development. Nevertheless, the realisation of positive social and environmental impacts depends partially on the dynamics of actors' inclusion in circular processes. We identify factors affecting the inclusion of farmers in agricultural residue supply chains in India and the socio‐ecological impacts thereof. We also introduce a framework for designing inclusive and just circular practices. Information, resources, co‐operation, and co‐design act as mediators to socio‐ecological impacts. The failure to consider these aspects may lead to unintended negative consequences, such as declined soil health or delays in other operations. The positive outcomes of selling the residue are linked to improved livelihood opportunities, local development and health. Selling is only a partial solution, and other straw management methods, such as incorporation, should also be applied.

“…The preference for paddy in Asia is a major factor in the continent's greater residue-burning rates than other continents. India's residue-burning rates are 93% and 30% higher than those of Pakistan and China (mainland), respectively (Dutta et al, 2022). Figure 2 illustrates the top five nations CO 2 eq emissions burning crop residues.…”

“…The main food supply for the Indian subcontinent is the rice farming system, which is practiced over roughly 44 million hectares of land in India. According to the average harvest index of 0.45, India produces 127 MT of leftovers annually (Dutta et al, 2022). Figure 1 shows the agricultural biomass share from various crops (Jain et al, 2018).…”

“…Farmers are forced to dispose of the leftovers because of various socioeconomic, organizational, technical, and commercial issues, which trigger various ecological problems. Each year, India produces 683 million tons of residue, with around 2/3 of that amount coming from cereal crop residues and the remaining from other crops that yield surplus residue (Jain et al, 2018;Srivastav et al, 2021;Dutta et al, 2022). An excess of 178 million tons remains after recycling over 500 million tons in various sectors, including industrial, residential, and livestock feed (Sangeet and Kumar, 2020).…”

Geopolymer concrete is a sustainable substitute for traditional Portland cement concrete. In addition, rising carbon taxes on carbon emissions and energy-intensive materials like cement and lime, impacts the cost of industrial by-products due to their pozzolanic nature. This research evaluates the compressive strength and flexural strength of geopolymer concrete, and the compressive strength of geopolymer mortar. Geopolymer mortar data were used for the strength assessment employing an analytical approach, and geopolymer concrete data were utilized for the strength and sustainability performances. Using artificial neural networks (ANNs), multi-linear regression (MPR) analysis, and swarm-assisted linear regression, compressive strength models were created based on experimental datasets of geopolymer mortar mixes with variable precursors, alkali-activator percentages, Si/Al, and Na/Al ratios. The strength and sustainability performances of geopolymer concrete blends with various precursors were assessed by considering cost-efficiency, energy efficiency, and eco-efficiency. The work’s originality comes from enhancing sustainable high-performance concrete without overestimating or underestimating precursors. Extensive experimental work was done in the current study to determine the best mix of geopolymer concrete by varying silica fume, ground granulated blast furnace slag (GGBS), and rice husk ash (RHA). A scanning electron microscopic study was conducted to understand the geopolymer matrix’s microstructure further. A comprehensive discussion section is presented to explain the potential role of RHA. The replacement of conventional concrete in all its current uses may be made possible by this sustainable high-performance concrete utilizing RHA.

“…India is an agricultural powerhouse that produces a wide variety of crops annually that are grown on an estimated area of about 140 million hectares . Owing to its massive year-round agricultural operations, the country also produces a humungous amount of crop residues such as cobs, husk, stalks, stubbles, etc., estimated by some reports to be north of 650 million tons (MT). , While some portion of the residues gets utilized in domestic and industrial sectors, a significant portion, amounting to some 178 MT, remains behind unutilized. , The disposal of crop residues is often challenging and expensive, forcing farmers to dispose them off by open field burning . The burning of surplus residues releases huge amounts of harmful air pollutants such CO, CO 2 , NO x , SO x , etc.…”

Biomass holds significant promise as a renewable feedstock for H 2 production. In this study, an integrated biomass pyrolysis and bio-oil catalytic steam reforming approach was explored for hydrogen production from biomass, focusing on a mixture of agricultural crop residues as the feed material. An optimal bio-oil yield of 40.6 wt % was achieved at 450 °C with a heating rate of 10 °C/min during pyrolysis. Using a LaNi 0.5 Co 0.5 O 3 catalyst, time-on-stream experiments exhibited a stable bio-oil conversion (80%) and average H 2 yield (60%) over a 12 h period. Furthermore, FESEM and Raman analysis of the spent catalyst revealed considerable coke formation, which contributed to reduced catalytic activity after 5 h. However, coke was predominantly graphitic in nature, which kept the catalyst active over the entire 12 h period despite significant coke coverage.
