Green nanotechnology is the study of how nanotechnology can benefit the environment, such as by using less energy during the manufacturing process, the ability to recycle products after use, and using eco-friendly materials. Nanotechnologies, according to this article, will not just initiate the next industrial revolution; they will also offer technological solutions. Green nanotechnologies could be expected to assist in the following: providing clean water to billions of people via novel filtration techniques and the ability to decontaminate dirty water; solving efficiency issues so as to increase the use of renewable energy; and, for waste management and environmental remediation. The article takes an in-depth look at the state of nanotechnology for the following applications: green manufacture; water treatment; renewable energy; environmental remediation and waste management; and, chemical substitution. The article cautions that the impact of nanoparticles on ecosystems remains unclear, and, as such, it is essential consumers are well educated so that nano-waste streams are under control, or at least well understood. Further research, the article adds, regarding nanomaterial risk assessments – over the life cycle of a nanomaterial – should be undertaken.
