The T-Shirt Chewing Enzyme Ready to Tackle Plastic Waste

“Over eight years they re-engineered LCC – now LCCICCG – to become a trained PET specialist.

The enzyme is now so efficient that it can completely break the PET polymer down to its constituent monomers—the chemicals producers need to make new plastic.

Prof Marty likens it to breaking apart a pearl necklace.

‘We are using an enzyme that you can consider a molecular scissors,’ he says. ‘We break down the link between the pearls, liberate the pearls and in this way, after purification, we can sell these pearls again.'”

High-Yield Rice Emits up to 70 Percent Less Methane

“Rice, one of the world’s key staples, is responsible for 12 percent of global methane emissions. Now, an international team of scientists has identified chemical compounds released by rice roots that determine how much methane the plants emit…

When the research team grew these low fumarate and high ethanol (LFHE) rice varieties at various field sites throughout China, the LFHE rice produced 70 percent less methane on average compared with the elite variety from which it was bred. The LFHE crops also have high yields at yields—8.96 tons/hectare on average, compared to the 2024 global average of 4.71 tons/hectare.”

The World Has Probably Passed “Peak Air Pollution”

“Global emissions of local air pollutants have probably passed their peak.

The chart shows estimates of global emissions of pollutants such as sulphur dioxide (which causes acid rain), nitrogen oxides, and black and organic carbon.

These pollutants are harmful to human health and can also damage ecosystems.

It looks like emissions have peaked for almost all of these pollutants. Global air pollution is now falling, and we can save many lives by accelerating this decline.

The exception is ammonia, which is mainly produced by agriculture. Its emissions are still rising.”

China Reduced SO2 Emissions by More than Two-Thirds in 15 Years

“Annual emissions of SO2 in China … rose steeply during the 1980s and 1990s. But they peaked in the mid-2000s, and over the last 15 years, they have fallen by more than two-thirds.

Putting emissions limits on coal plants and introducing desulphurization technologies that remove SO2 from smokestacks were critical drivers of this decline.”
