nonpolluting
Nonpolluting refers to substances, processes, or activities that do not cause harm or contamination to the environment. This concept is central to environmental sustainability and efforts to minimize negative human impact on ecosystems. A nonpolluting energy source, for example, would generate power without releasing greenhouse gases or other harmful emissions into the atmosphere. Similarly, a nonpolluting manufacturing process would avoid the discharge of toxic waste into waterways or the ground.
The idea of nonpolluting is not always absolute. Often, it refers to a significant reduction in pollution
