    The use of effective and environmentally acceptable synthetic processes or procedures for the synthesis of nanomaterials is expanding substantially as a result of the nanotechnology relevance and its influence on numerous disciplines, as seen in the recent advancements in the field. This paper is a review of the published literature on the subject of environmentally friendly production of iron-based nanoparticles. In contrast to many conventional methods for the nanomaterials synthesis, the plant-mediated synthesis appears to be a highly intriguing and ecologically benign method. This is because of its simple methodology and eco-friendly approach. The created nanoparticle is simpler to manufacture, more stable, and effective in a range of application areas, as compared with conventional methods of synthesis. As a result, this analysis includes details on the various sources used so far and how the materials were created to be used in environmental applications, paying particular focus on the iron-based nanoparticles.

    A wide range of hard adulterants in waste water are generated from different industries as a by-product of the organic compound. In this review, the cationic dye Malachite Green removal from wastewater by photocatalytic route by using various metal oxide nanoparticles is analysed. The effect of some specific parameters like the method of preparing the catalyst, the initial concentration of dye, the amount of nanocatalyst required for degradation, the initial pH of dye solution, type of light source used, and time of light exposure required for removal of dye were specially incorporated. Some general conclusions were made based on the pivotal analysis of literature available. With a view to reach higher removal efficiency, in an economical manner, some optimal testing conditions on degradation of these hard dyes should be carried out.

    Pesticides are helping to meet up the demand for population growth in today's agriculture. They are also being utilized for numerous issues including domestic pests control, home gardening, and disease vectors. Though, they are extremely poisonous in nature. They also cast false impact on surroundings. When used for the agricultural purpose, their toxic residues are continually left behind, and thus forming a major origin of pollution. The unwanted risky chemical groups are contaminating natural assets at a shocking rate. Agricultural pesticides left behinds are among the most harmful contaminants to the soil and water. Removing them from wastewaters is critical as they have bioaccumulation potential, toxicity, and a high persistence. Pesticides have long been used to improve manufacturing efficiency and extend the shelf-life of food goods. Their residues should be removed from food products and waters to limit human pesticide exposure. To remove pesticides, various processes are usually employed which include the adsorption process, membrane processes, and improved oxidation reactions, while microorganisms degrade them naturally i.e. bioremediation/biodegradation. Many organic and inorganic materials have been fabricated for rapid and complete degradation of pesticides. Semiconductor materials contribute to the pesticide oxidation and reduction because they have a proclivity for producing radicals through the charge separation. This review focuses on the pesticides’ taxonomy, functioning, their associated risks to human and environment, and degradation methods involving the current discoveries and progress in the utilization of several approaches for their probable removal from wastewater. The advanced oxidation, adsorption, bioremediation, photocatalysis, semiconductor materials, phytoremediation, and membrane technologies are some of these processes discussed in this investigation. In the upcoming researches, it will be required to generate the novel concepts in the current farming that will reduce the need of toxic pesticides and enable manufacturing of selective to target and less persistent pesticides.

    Fossil fuels are used increasingly day by day everywhere on the globe and related to environmental issues like the environmental problems and heating. During this time, attempts are made to seek out sustainable different energy source which is affiliated with fossil material. The foremost important fossil material is plant biomass, especially wood, of the premise of cellulose percentage. However, those materials constituent of lignin have a content of 18-30%. Lignin is mainly used for fuel and has many valuable applications like, nanoparticles synthesis, polycarboxylic acid, supercapacitor electrode, photocatalyst, photovoltaic, etc. Recently, researchers highlighted more sustainable bioenergy production technologies. This review paper focused on different categories application of lignin within the industrial sector which could be a totally sustainable energy conversion.
