The researchers used a special bacteria to help break down pig bristles waste into compost faster and better. They tested this bacteria in different composting methods and found that it improved the quality of the compost by increasing the levels of important nutrients and making sure there were no harmful metals present. The compost made with the bacteria was also more decomposed and stable, making it a useful fertilizer. Overall, using this bacteria during composting can help get rid of tough waste like pig bristles and create a valuable product for farming.
