The paper industry is energy-intensive. According to the EIA, the industry consumed 1483.2 trillion British thermal units (Btu) of energy in 2019. At the same time, the CO2 emissions of the paper industry
reached 48 million tons. Utilising renewable energy is a well established way to try to reduce the emissions footprint of processing steps reliant on electricity. But replacing natural gas needed for high temperature drying is harder. In what could well be a world-first, a NZ company is replacing natural gas in its drying hood with geothermal steam instead. https://www.eeca.govt.nz/about/news-and-corporate/news/essitys-groundbreaking-geothermal-project-a-world-first/
Green methanol is a low carbon liquid chemical and fuel produced from sustainable biomass, often called bio-methanol, or from captured CO2 & hydrogen produced from renewable electricity, referred to as e-methanol. It is a multipurpose liquid which is easier to store and handle than green hydrogen. It's been slow to get much traction, but is showing promising signs of renewed interest with LEGO and others looking at its use in their operations. https://www.reuters.com/article/renewables-plastic-lego-novo-nordisk-idAFL8N36N1YN
