Shanghai now recycles 98% of industrial waste after 6-year sorting overhaul

By / / Good News For Humankind

Shanghai’s waste overhaul has pushed industrial recycling to 98%, meaning almost nothing from the city’s factories ends up in a landfill anymore. Six years in, companies have built whole businesses around the idea that scrap is just raw material in disguise — one Jinshan firm now processes 130,000 tons of aluminum cuttings a year, while another turns used cooking oil into bioplastic for take-out containers sold worldwide. At the neighborhood level, a Hongkou pilot composts 220 pounds of kitchen scraps daily into fertilizer for the gardens right outside residents’ doors. For a city of 25 million, it’s a hopeful glimpse of what circular living can look like when waste is treated as treasure rather than trash.

China connects the world’s first commercial supercritical CO2 power generator to the grid

By / / Good News For Humankind

Supercritical CO2 power generation has reached a historic milestone as China’s Harbin Electric Corporation becomes the first in the world to operate a commercial-scale turbine using supercritical carbon dioxide — and connect it to a live national grid. The technology replaces conventional steam with pressurized CO2, achieving thermal efficiencies above 50% compared to roughly 40% for the best modern steam plants. Beyond efficiency, the turbines are dramatically more compact and work across multiple energy sources, including solar, nuclear, and industrial waste heat. China’s success gives the global engineering community proof that this long-pursued technology can actually work at scale, likely accelerating development timelines worldwide.

Hawaii becomes the first U.S. state to charge visitors a climate resilience fee

By / / Good News For Humankind

Hawaii’s climate resilience fee, signed into law in May 2025, makes the state the first in the U.S. to require visitors to pay a dedicated charge funding environmental protection. Governor Josh Green’s signing of Senate Bill 1396 creates a roughly 5-per-trip levy directed toward coral reef restoration, coastal defense, and sea-level rise adaptation. With around 10 million annual visitors, the fund could generate hundreds of millions of dollars each year. The move positions Hawaii as a potential national model for making tourism directly accountable for the ecological costs it creates.
