Waste oil refining biodieselHow much investment, conversion rate in the number?
Waste oil refining biodiesel investment is based on the scale of production and the production of the selected process set, you do not say how large-scale here to answer your question
Conversion problem: raw water mixed in 3 or less, a ton of raw materials can be converted to biodiesel about 0.85 tons, methyl ester plant asphalt about 0.12 tons, but also some of the former low carbon fraction of about 0.03
But the small scale of investment: Nissan 10 tons, with an annual output of 3000 tons in 2 million, excluding factory costs. I suggest that you at least to Nissan 20 tons, with an annual output of 6000 tons of scale, if the collection of raw materials is no problem, so that the size of the utilization rate of equipment, and the production cost is 6000 years worthwhile. Tons of scale, investment will be around 5 million.
