The future of paper could come from gene-edited trees

illuminem summarizes for you the essential news of the day. Read the full piece on The Washington Post or enjoy below:

🗞️ Driving the news: Scientists at North Carolina State University are developing gene-edited trees with reduced lignin content, aiming to make paper production more efficient and environmentally friendly
• These trees, edited using CRISPR technology, require less energy and chemicals for pulping, potentially lowering the industry's carbon footprint

🔭 The context: Lignin, a complex polymer found in all land plants, makes wood rigid but complicates the production of paper and other pliable products
• Traditional methods of lignin removal are energy-intensive and polluting
• The researchers used machine learning to identify gene-editing strategies, creating tree variants with up to 50% less lignin and higher cellulose content

🌍 Why it matters for the planet: Reducing the environmental impact of the paper industry is significant, as it emitted 31.2 million metric tons of CO2 equivalent in the U.S. in 2022 alone
• Gene-edited trees could help cut emissions and resource use, aiding in climate change mitigation efforts

⏭️ What's next: The researchers plan to commercialize these trees by 2040, with potential uses extending beyond paper to biofuels
• However, they face regulatory, ecological, and public perception challenges, similar to those faced by genetically modified crops

💬 One quote: “We’re compelled to actually use that technology to breed trees and revolutionize forestry.” — Rodolphe Barrangou, North Carolina State University

📈 One stat: The U.S. paper industry emitted 31.2 million metric tons of carbon dioxide equivalent in 2022
