Used Cooking Oil

Used cooking oil is the most demanded residue by the first and second generation biodiesel plants. It is also highly demanded by refineries that can convert it in HVO. As a waste that is, its characteristics are not homogeneous Types of UCO:

• Premium UCO
• FFA: max 3%


• Normal UCO
• FFA: max 5%

POME

Palm Oil Mill Effluent

• POME is a waste water/sludge arising from palm oil production usually released to open ponds. The oil extracted from POME is often referred to as “Palm Sludge Oil” or “Sludge Palm Oil” · Really high content in sulfur and phosphorus

Glycerine

• CRUDE GLYCERINE
• By-product of biodiesel production with glycerol content between 60 and 82%. It can be used by different industries: oleochemistry, biogas, animal feed.
• REFINED GLYCERINE
• Glycerine with glycerol content between 92 and 99.5% and can be certified Kosher. It can be used in food or pharmaceutical industries

Soapstocks

Lorem ipsum dolor sit amet consectetur.

Waste obtained from the soap used in the crude oil chemical neutralization. · Treated with strong acid you get a fatty part that is the olein. Quality: 1 mt of soapstock varies from 20-50% of oleins.

Oleins

Oleins are a waste generated from the chemical refining of crude oil. Their characteristics vary depending on the type of seed from which they come (rapeseed, soy or palm mainly)

Free Fatty Acids

CHARACTERISTICS OF FREE FATTY ACIDS A Pre-treatment (esterification) is necessary to reduce acidity prior to convert into biodiesel. FFA min 70% Sulfur max 20ppm Phosphorus max 20ppm MIU max 1% Lodine Value vary depending on the kind of seed: Palm min 50, Soy and Rape min 100
