The aviation industry accounts for a significant share of global carbon emissions. In response, the international community is expanding mandatory use of Sustainable Aviation Fuel (SAF), which is produced from organic waste or biomass and is expected to significantly reduce greenhouse gas emissions compared to conventional fossil-based jet fuel. However, high production costs remain a major challenge, leading some airlines in Europe and Japan to pass SAF-related costs on to consumers. https://techxplore.com/news/2026-02-trash-takeoff-kg-sustainable-aviation.html Energy & Green Tech Wed, 04 Feb 2026 11:02:53 EST news689425321 As we shift toward more sustainable fuels, natural gas and biogas, which mainly contain methane (CH4), have become important sources of energy and raw materials for chemical production. However, these gases also contain impurities that must be removed before use.
