An example of a wastewater treatment system. Sanitary engineering, also known as public health engineering or wastewater engineering, is the application of engineering methods to improve sanitation of human communities, primarily by providing the removal and disposal of human waste, and in addition to the supply of safe potable water.
Sanitation is not high on the international development agenda, and projects such as those relating to water supply projects are emphasised. [ 56 ] The Joint Monitoring Programme for Water Supply and Sanitation of WHO and UNICEF (JMP) has been publishing reports of updated estimates every two years on the use of various types of drinking-water ...
There are ambiguities in the definition of green chemistry and how it is understood among broader science, policy, and business communities. Even within chemistry, researchers have used the term "green chemistry" to describe a range of work independently of the framework put forward by Anastas and Warner (i.e., the 12 principles). [12]
The Chemistry, Biology, Physics and Design Technology was last updated for first teaching in September 2014, with syllabus updates (including a decrease in the number of options), a new internal assessment component similar to that of the Group 5 (mathematics) explorations, and "a new concept-based approach" dubbed "the nature of science". A ...
Quantitative chemical analysis is a key part of environmental chemistry, since it provides the data that frame most environmental studies. [11] Common analytical techniques used for quantitative determinations in environmental chemistry include classical wet chemistry, such as gravimetric, titrimetric and electrochemical methods.

This project was called the Erdos Eco-Town Project in a town called Erdos in the Inner Mongolia Autonomous Region of China. It was a collaboration between the Dongsheng District government in Erdos and the Stockholm Environment Institute and aimed to save water and provide sanitation services in this drought-stricken and rapidly urbanizing area ...

Some Wikipedians have formed a project to provide information related to chemistry. The main efforts focus on providing articles clearly written articles that give an overview of the topic, all supported by reliable sources. The Chemistry portal is maintained at Portal:Chemistry and the project banner is {{WikiProject Chemistry}}.
