Advanced Biodiesel Transesterification
EN 14214 biodiesel directly from 100% waste vegetable oil, without a biodiesel distillation plant.
More Performance. Less Equipment. Lower Cost.
Used cooking oil is the most attractive biodiesel feedstock, low cost, widely available and strongly incentivized as a waste-based raw material. But it is also the most demanding: high free fatty acid content and impurities make it difficult to reach EN 14214 quality with conventional technology.
Most conventional plants solve this by adding a downstream biodiesel distillation unit, driving up capital investment, energy consumption, plant footprint and operating costs. Save Tech took a different path: our proprietary reaction technology and process design achieve EN 14214 compliant biodiesel directly from 100% waste vegetable oil, with no biodiesel distillation at all.
How the Process Works
Feedstock Pre-Treatment
Used cooking oil is filtered and conditioned: solids, water and impurities are removed to prepare a consistent reaction feed.
FFA Conversion
The high free fatty acid content typical for waste oils is converted upstream, the key to processing 100% UCO without quality loss.
Advanced Transesterification
Save Tech's optimized reaction technology converts the oil with methanol and catalyst under precisely controlled conditions.
Phase Separation
Glycerol is separated as a valuable by-product; the methyl ester phase moves on to purification.
Methanol Recovery
Excess methanol is recovered and returned to the process, reducing raw material consumption and operating costs.
Purification & Drying
The biodiesel is purified and dried to meet EN 14214, directly, with no distillation step required.
