“…Use of combine harvesters generates an enormous amount of 'root-bound and loose crop residues' which are difficult to manage (Ravindra et al, 2019). It is reported that due to very short time interval (10-20 days), labour scarcity, unavailability of farm implements to plough back the stubbles into the soil or spread the stubbles as mulch, the farmers' resort to on-site burning of crop residues (Shyamsundar et al, 2019;Kaur, 2020) (Figure 5). Absence of appropriate crop residue management technology and lack of awareness about the downside of crop residue burning also drive the farmers to stubble burning (Chawala and Sandhu, 2020).…”

Nexus Between Crop Residue Burning, Bioeconomy and Sustainable Development Goals Over North-Western India

et al. 2021

The crop residue burning in India particularly North-western India is responsible for air pollution episodes and public health concerns; greenhouse gases emissions and radiation imbalance; and declining soil organic matter and soil productivity. The objectives of this paper are to estimate the crop residue burning and emissions from crop residue burning, to recommend interventions in crop residue management and to propose a crop residue management-bioeconomy model incorporating strategies to sustainably manage the crop residues through interventions that enable waste valorization, food and nutritional security, farmers’ livelihood and sustainable agricultural production system. A national inventory on crop residue burning including the pollutant species was prepared using the IPCC methodology. The crop types included for the estimation are cereals, pulses, oilseeds, sugarcane, cotton, jute and Mesta. The total amount of crop residues generated and burned for the year 2017–18 was estimated at 516 million tonnes and 116 million tonnes respectively. It is estimated that 116.3 Tg of crop residues burning released about 176.1 Tg of CO2, 10 Tg of CO, 313.9 Gg of CH4, 8.14 Gg of N2O, 151.14 Gg of NH3, 813.8 Gg of NMVOC, 453.4 Gg of PM2.5, and 935.9 Gg of PM10. The emission estimates can be a proxy to prepare the national level inventory of air pollutant species from crop residue burning. The crop residue management (CRM) demands a transition from the traditional zone of CRM to bioeconomy zone of CRM, wherein the interventions aim at the sustainability of agroecosystem. The proposed bioeconomy model has a four-pronged strategy that includes smart agriculture practices, waste bioeconomy involving aspirational principles of bioeconomy, capacity building of stakeholders’ and proactive government policy. Sustainable agricultural bioeconomy provides ample opportunities to reduce crop residue burning, increase farmers’ livelihood and decarbonize the agricultural production. India’s efforts and policies can provide lessons for other agricultural regions having similar environmental constraints.

“…Research that touches upon the issue of selling and removal of straw expects the impacts for farmers and local communities to be somewhat positive due to increased livelihood possibilities and health reasons, yet notes that negative aspects, such as declining soil health, might present challenges (Athira et al, 2019; Bhatt et al, 2022; Bhattacharyya et al, 2021; Chauhan et al, 2022; Downing et al, 2022; Kaur, 2020; Kumar & Singh, 2021; Venkatramanan et al, 2021). Selling straw for industrial use is also a preferred option for many farmers (Bhatt et al, 2022; Kumar & Singh, 2021).…”

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

2023

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.

“…Rice is one of the most widely used cereals for the global population. During its harvest, approximately 134 million tons of rice husks are produced annually, which have no nutritional benefits for humans and are rarely used for animal feeding. , Many studies have reported the open-field burning of rice husks causing an alarming increase in air pollution by releasing hazardous particulates and carcinogenic gases. − The abundance and poor management of rice husks emphasize the necessity for alternative ways of utilizing rice husks.…”

This study investigates the detailed ash transformation process during the combustion of rice husks in entrained flow conditions. The experiments were conducted in a lab-scale drop tube furnace at 1200 and 1450 °C in pyrolysis/devolatilization (using N 2 ) and combustion (using air) conditions. The detailed ash transformation process during the different fuel conversion stages in combustion (i.e., devolatilization and char combustion) was investigated by comparing the results obtained in the pyrolysis/ devolatilization experiments with the combustion experiments. The resulting residual chars, ashes, and particulate matter (PM) were collected and characterized by scanning electron microscopy and energy-dispersive X-ray spectroscopy (SEM−EDS), X-ray diffraction (XRD), inductively coupled plasma atomic emission spectroscopy (ICP-AES), ion chromatography (IC), and CHN analyses. Furthermore, the obtained results were interpreted via thermodynamic equilibrium calculations (TECs). For all investigated conditions, Si, Ca, and Mg were retained entirely in the coarse ash and char fractions (>1 μm). Meanwhile, K and P were found in coarse ash/char fractions and fine particulate fractions (<1 μm).A moderate, at 1200 °C, to high share, at 1450 °C, of the detected K and P was found in the fine particle fractions after combustion. The majority (>95%) of the detected S and Cl were volatilized during the experiments. The study showed an accumulation of minor ash-forming elements (i.e., K, Ca, Mg, P) on the inner part of rice husk chars, initiating melt formation during the char combustion stage. The identified melt at 1200 °C after combustion was rich in Si with minor amounts of K, Ca, Mg, and P. The share of molten ashes was increased at 1450 °C compared to that at 1200 °C. Overall, the results presented in this work reveal detailed insights into the ash transformation processes taking place in different parts of the fuel during the combustion of rice husks in entrained flow conditions.
