Biodiesel Network September 28th: ​​According to "Oil World", global biodiesel production in 2015 is 28.95 million tons, down 1.5 million tons from last year, still the second highest in history. US production was 4.36 million tons, 4.22 million tons last year, 3.45 million tons in Brazil, 3 million tons last year, 1.83 million tons in Argentina, down from 2.58 million tons in the previous year, and Indonesia's output was 2.12 million tons, lower than the previous year. 2.87 million tons. Germany produced 2.95 million tons, 3 million tons last year, 2.1 million tons in France and 2.05 million tons last year. From the data, we can see that the global biodiesel production has shown a downward trend this year, which is affected by the world economic situation. According to the biodiesel network, there are some domestic biodiesel production capacity, but the actual production is really limited, which has a lot to do with domestic industrial policies and market conditions. We look forward to the policy landing and the market is getting better. Otherwise, the domestic biodiesel production will further shrink, and even many new projects will not be built with confidence. The biodiesel enterprises that have been producing for many years should always consider transformation.
