In the era of rising global population and environmental apprehension, the critical necessity is to bring sustainable solutions through innovations in modern science. In 2017, the United Nations urged all countries, through its Sustainable Development Goals (SDGs), to recognize the interconnectedness in alleviating poverty, health improvement, environmental protection, and economic development in efforts to reduce inequality across multiple sectors. Nanotechnology plays a crucial role in advancing environmental sustainability by providing inventive solutions to compelling environmental challenges and promoting a more efficient and resilient approach to resource management and conservation. In November 2020, representatives from leading nanotechnology research institutes gathered for an international workshop on “Nanotechnology for a Sustainable Future”. 

 

While nanotechnology offers significant promise for tackling sustainability issues, it is crucial not to disregard the harmful effects that nanomaterials can have on both the environment and human health. The integration of the principles of environmental sustainability into nanotechnological methodologies can make them greener, cleaner, and more environmentally friendly. Green nanotechnology has emerged as a widely recognized and promising field of science for environmental sustainability through various applications in renewable energy, environmental remediation, (nano)material synthesis, and biomedicine. It emphasizes the use of eco-friendly methodologies using environmentally sustainable materials to bring a balance between economic, social, and environmental factors to maintain the health and integrity of various ecosystems. The global green nanotechnology market for sustainable environmental applications is significantly increasing and will reach a pinnacle of ~417.35 billion in 2030.

 

Green chemistry familiarly called as sustainable chemistry mainly focus on the designing of pharmaceutical products by processes that decreases the use of chemicals and hazardous substances generation, Now a days plant based medicines engineered with Novel drug delivery like nanoparticles, microspheres etc plays a major role in the treatment of several life threatening diseases by their quick drug delivery to the target site. This review focus on the green chemistry principles for the formulation of pharmaceutical nanoparticles specially from plant based compounds and their formulation techniques.CleanInnova Green Nanotechnology, in phyto formulations, maintains the environmental sustainability in the production of nanoparticles, providing harmless to human health and also to the environment. Enhancement of energy efficiency, reduction in waste production and emission of gases, and minimal consumption of non-renewable raw materials are the main advantages of green nanotechnology. Green chemistry offers a great opportunity to stop the adverse effects before their occurrence during the synthesis of nanoparticles.
