Fertilizer management is crucial to maintaining a balance between environmental health, plant health, and total crop yield. Farmers are overutilizing fertilizers with a mind set to enhance the productive capacity of the field, which adversely impacts soil fertility and causes serious environmental hazards. To mitigate the issues of over-utilization of fertilizers, controlled-release fertilizers were developed using nitrogen fertilizer (ammonium chloride) loaded on cellulose nanofibres (named CNF*N).

Currently, the packaging material is composed of fossil fuel-based plastics, which are non-biodegradable. Therefore, the biodegradable coating material developed from cellulose can be explored for applications like packaging, cutlery, bowls, straws, etc. The aim of the present study was to develop an agro-waste-based sustainable coating material using a waste-towealth approach. The study focused on transforming cellulose and cellulose nanofibre (CNF) derived from rice straw into biodegradable polymeric coatings.

In the present scenario of accelerated research on production of ecofriendly bioethanol, second-generation bioethanol generation has particularly gained wide attention. These utilize agricultural feedstock and industrial residues, therefore assisting in their management without presenting any competition for food supplies. Rice straw is one such abundantly generated agricultural residue with a great potential for sustainable production of bioethanol.

Temporal variation in forest cover, the largest terrestrial ecosystem on Earth, influences the climate at both local, regional, and global scales through physical, chemical, and biological processes. At the same time, forests sequester and store more carbon dioxide than any other terrestrial ecosystem and act as a "natural brake" in climate variation. Here, we have made an attempt to assess the spaio-temporal variation in forest biomass combining field-based and remote sensing and machine learning approaches.

Rice straw is a waste product generated after the harvesting of rice crops and is commonly disposed of by burning it off in open fields. This study explored the potential for the extraction and conversion of cellulose to cellulose nanofibres (CNFs) to be used as smart delivery systems for fertilizers applications. In this study, alkali, steam explosion, and organosolv treatments were investigated for cellulose extraction efficiency. The morphological characterization of cellulose showed smooth fibrillar structures.

Cellulose nanofibres (CNF) have emerged as advanced systems for controlled, smart delivery of N-fertilizer owing to their surface modification properties. However, to realize the true potential of this nanomaterial, its biodegradation analysis would be crucial to understanding its impact and fate when exposed to the environment. In this study, the main focus was to investigate the effect of N-fertilizer loaded CNF (electrostatic interaction between the negatively charged COO– group on CNF and the positively charged ammonium ion) on the microflora of the soil.

Commercial production of microalgae biofuel is not economically feasible since it cannot compete with the price of fossil fuels. Algal biofuel could be cost-effective if high-value co-products are produced from microalgal biomass before it is converted into biofuel. Thus, this research aims to demonstrate a circular biorefinery process of producing bio-crude bio-oil as well as high-value products like carotenoids from a marine microalga Nannochloropsis oceanica.

Microalgae-based systems are one of the most sustainable substitutes for naturally occurring compounds, such as pigments, lipids, fatty acids, carotenoids, and proteins, which are well known to have various applications. In the past few decades, vigorous research has been conducted in the field of microalgae-based commercial applications. Global market trends have flourished tremendously with the increase in research and development of microalgae-based systems, focusing on the innovation of processes and development of products.

Global rise in CO2 levels, combined with growing concerns about greenhouse gas emissions, has prompted the adoption of low-carbon emitting processes in order to create a safer, more economically viable, and sustainable environment. Carbon capture by woody biomasses, following the 3R principles of advanced carbon capture, utilization, and storage practices, may boost the circular bioeconomy and help to limit the global rise in temperature below 1.5°C.

The world is recognizing the relevance and scope of Sustainability Science (SS) as it integrates the disciplines ranging from pure sciences and social sciences and their specializations. Hence, a balance between policies, research, and direct action is integral to the field of SS. Interdisciplinarity is important for SS, and this is a relatively new area. Hence, experiments done within the scope of SS need to be recorded and intensive dissemination of lessons learnt (Haider, 2018).
