生物油专题系列3：航空减碳当前唯一解，SAF扩产周期中废油脂资源稀缺增值

Investment Rating - The report maintains a "Buy" rating for the environmental industry, specifically focusing on sustainable aviation fuel (SAF) and its related sectors [1]. Core Insights - Sustainable Aviation Fuel (SAF) is identified as the only feasible solution for carbon reduction in the aviation sector, with potential carbon emission reductions of 80%-85% throughout its lifecycle [9][10]. - The demand for SAF is expected to surge due to regulatory mandates in the EU and UK starting in 2025, leading to a significant increase in prices and profitability for SAF producers [15][16]. - The supply of used cooking oil (UCO), a key raw material for SAF production, is projected to become increasingly scarce, driving up its value and creating investment opportunities in companies with access to these resources [4][19]. Summary by Sections 1. SAF as the Only Viable Solution - The aviation sector is a major source of greenhouse gas emissions, with liquid fuels being irreplaceable due to high energy density requirements [9]. - SAF can be blended with traditional jet fuel without requiring major modifications to existing aircraft [10]. 2. SAF: EU Regulations and Market Dynamics - The EU will enforce mandatory SAF blending ratios starting in 2025, with targets set for 2030, 2035, 2040, 2045, and 2050 [16][18]. - The projected SAF demand in the EU is expected to reach 3,662 million tons by 2050, with a compound annual growth rate of 15% from 2025 to 2050 [19][20]. 3. UCO Supply and Demand - China's annual UCO utilization is approximately 400 million tons, with significant potential for growth, but collection remains challenging [37]. - The demand for UCO is expected to rise sharply as SAF production increases, with long-term supply shortages anticipated [4][19]. 4. Investment Recommendations - Companies with scarce UCO resources, such as Shanhigh Environmental and Longkun Technology, are recommended for investment due to the increasing value of waste oil resources [4]. - The short-term supply constraints in SAF production are expected to lead to substantial profits for SAF manufacturers [4].
