“…With mounting public awareness and governmental push, recycling initiatives, especially for materials like paper, plastic, and metal, have significantly expanded. The benefits extend beyond waste reduction, creating job opportunities and promoting sustainable consumption and production patterns [17][18][19][20].…”

India, having one of the largest agro-basedeconomies in the world, produces a significant amount of wastes, both from farming activities and agro-based industries. These wastestreams pose critical environmental and public health challenges that necessitate efficient management strategies.The present review examines the current status and future perspectives of waste utilization in India. We have attempted to criticallyidentify the most prominent features of effective waste management and the constraints in resource recovery for achieving the sustainable development goals. This review provides an overview of the prevailing practices in waste utilization, highlighting various methods employed and the types of industries that can benefit from this approach. In particular, techniques such as co-processing, recycling, waste-to-energy conversion, and industrial symbiosis to be extensivley made accessible to maximize the value derived from wastes. Some of the major challenges we identified include limited awareness, inadequate infrastructure, and regulatory gaps, which can significantly hinder the optimal utilization plans. To address these challenges, the review proposes potential strategies such as awareness campaigns, infrastructure development, technology transfer, and policy strengthening both at community and organizational levels. The findings of this review canshed light on the current landscape of waste utilization in India and present pathways for a more sustainable and efficient approach in the near future.

“…About 60% of these emissions result from chemical reactions, whereas the remaining 40% are due to the combustion of fossil fuels during cement production [ 24 ]. Attempts to reduce the massive carbon footprint of cement production have given rise to adopting nontraditional stabilisation agents, such as waste materials, lignosulfonate, epoxy resins, polymers, geopolymers, and biopolymers [ 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 ]. These additives are cost-and-time-effective alternatives to conventional materials.…”

Recently, the improvement of the engineering properties of soil has been centered on using sustainable and eco-friendly materials. This study investigates the efficacy of three biopolymers: Acacia, sodium alginate, and pectin, on the unconfined compressive strength (UCS) of dune sand. The UCS test measured the effects of the biopolymer type and concentration, curing intervals and temperature, and moisture loss. The changes in the morphology caused by the biopolymer addition were examined via scanning electron microscopy (SEM). Results indicate that the UCS of the biopolymer-modified sand increased with biopolymer concentration and curing intervals. Varying the curing temperature from 25–110 °C, slightly affected the strength of the acacia-modified sand specimen, increased that of the sodium alginate-modified sand specimen up to a temperature of 85 °C, and continued to decrease that of the pectin-modified sand specimen as the temperature was increased from 25 to 110 °C. The SEM images indicated that the biopolymer’s presence within the sand pores significantly contributed to the strength. Bond decomposition occurs at temperatures greater than 110 °C for sodium alginate and pectin-modified sands, whereas bonds remain stable at higher temperatures for the acacia-modified sand. In conclusion, all three biopolymers show potential as robust and economic dune stabilisers.

Introduction The scope of implementing innovative research findings aimed at sustainable development goals seems to be inherently limited by economic and social acceptance, despite their technical efficacy. There exists a huge demand for coordinated efforts to mitigate the negative impacts of the so-called ‘development’ activities that are tampering with the very existence of humanity, natural resources, and the environment. Agriculture, though historically the first and foremost occupation of humans, has always been intrigued by nature at the cost of natural calamities and uncertainties in ensuring the availability and timely distribution of essential resources. In the modern context of water-energy-food paradigms, the agriculture sector can play a pivotal role in bolstering the state economy in multifaceted ways by assuming the adaptability of recent scientific advancements to the core functional attributes of sustainability. In this scenario, the concept of regenerative agriculture can be better understood as a holistic, self-adaptive, and integrated approach towards not only bringing about a revolutionary breakthrough in agricultural productivity but also providing a retroactive and reconstructive strategy for minimizing the inevitable consequences of destructive developments. An organized, synthesized approach in this direction would certainly culminate in fabricating close-connected, supportive interlinking pathways for related fields of science and technology to make them more beneficial towards the responsible productivity expected from the agriculture sector [1]. The prospects of environmental research have established a close interlink with the agriculture sector, mainly through the attributes of material, energy, and living species. It is envisaged that the environment is a bigger space with multiple spheres of activity, while agriculture comprises a smaller sect with limited but well-defined interactions with the environment [2]. Even though it is generally accepted that most of these interactions (such as soil quality and crop growth, water requirement and crop selection, raining pattern and cropping seasons, etc.) are mutually directed, one could perceive them as if initially driven by agricultural activities. However, there are some other interactions where environmental attributes are driving agricultural activities and outputs [3-5]. Most of these interactions are, nonetheless, subtle and complex, and little is known about their individual lead roles. Hence, it is important to identify the specific attributes of some of the well-known interactions and look for the key drivers towards addressing the original problem of agriculture and sustainability. A dynamic interaction between agriculture and environment is observed to be well-reinstated through the simultaneous existence and exchanges of the energy, materials and activities (Figure 1). It is, however, expected that a compensating step is essential to redirect (or push forward) such exchanges without creating adverse environmental impacts as well as agricultural losses.
