New asphalt binder alternative is less toxic, more sustainable than conventional blend

Asphalt is primarily known for use in roadways, but it’s also used to pave playgrounds, bicycle paths, running tracks and tennis and basketball courts—all platforms for activities where breathing toxic fumes can be dangerous. Outdoor use on driveways, rooftops and parking lots, especially in the Arizona sun, also can lead to toxic fume exposure.

Upgrading iron and steel plants could save equivalent of two years of global carbon emissions

Upgrading, or retrofitting, the world’s iron and steel processing plants early could reduce carbon emissions by up to 70 gigatonnes by 2050, roughly equivalent to two years’ worth of net global carbon emissions, according to a new study published in Nature and led by UCL researchers in collaboration with Tsinghua University, Peking University and King’s College London.
