The ‘environmental crime of the century’ solved


In 2016, sensors began picking up an illegal gas billowing into the atmosphere from eastern China. The gas, CFC-11, was banned in 2010 under the Montreal Protocol — the international treaty to eliminate substances that wreck the Earth’s protective ozone layer. Where were the gases coming from?

China’s new frontier for VOC regulations


Volatile organic compounds (VOCs) combine with nitrogen oxide to create ozone, a key precursor to smog. When energy use surges in the autumn and winter seasons, particulate matter and ozone increase to dangerously high levels. Air emission reform in China. Targets for regulation.

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. Why HFCs are a climate problem.

An enduring threat to water?

Envirotec Magazine

In 2016, the detection of PFAS in drinking water in the USA took a step forward. 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.

Nitrous oxide levels are on the rise

Envirotec Magazine

Nitrous oxide is a greenhouse gas and one of the main stratospheric ozone depleting substances on the planet. The authors of the study suggest the use of nitrogen fertilizer in regions where there is already a large nitrogen surplus will have to be reduced, to achieve N20 emissions targets.
