US, China commit to phase down climate-warming HFCs from refrigerators and air conditioners – but what will replace them this time?

Renewable Energy World

CFCs were destroying the ozone layer high in the Earth’s atmosphere, which is essential for protecting life from the Sun’s harmful ultraviolet radiation. But when they break down, they create chlorine that reacts with the protective ozone, letting dangerous radiation through to the Earth’s surface. This article was updated Sept.

An enduring threat to water?

Envirotec Magazine

An alternative approach requires an ozone generator to add the chemical oxidant, ozone, in a process termed ozofractionation29, 30. Major drawbacks arise with this approach as a result of using ozone, which is a chemical oxidant. So, using ozone will create additional PFAS that are not amenable to removal by fractionation.

The Environmental Impact Of Biomedical Waste And How To Reduce It

The Environmental Blog

The purpose of this article is to explore the environmental impact of biomedical waste and to discuss ways to reduce it. Another approach is to use alternative technologies for treatment and disposal, such as microwave or ozone treatment. This type of waste can be hazardous to human health and the environment if not managed properly.
