Researchers say straw from giant cotton hub could be combined with other farm waste to save millions of tonnes of CO2
XIANYANG - China’s largest cotton-producing region could turn two of its dirtiest farm by-products into a climate win, according to new research that also underscores the reputational risks brands face when engaging with Xinjiang.
A study in the peer-reviewed journal Agricultural Ecology and Environment models how co‑pyrolysing cotton straw and discarded plastic mulch film to make biochar could deliver annual net reductions of around 20 million tonnes of CO2 equivalent in Xinjiang.
