Purpose
Share with this committees and participants the experience and challenges faced by Oxiteno in establishing a new plant that processes vegetable feedstock, for instance palm kernel oil.

Investment
Oxiteno invested more than US$ 100 million, building a new Fatty Alcohol industrial unit in Brazil, the Oleoquimica
The new unit has capacity to process 100,000 tons/year of Vegetable Oils to produce Fatty Alcohols, Fatty Acids and Glycerin
First Fatty Alcohol unit in Latin America
The new unit also produces different kinds of Fatty Acids, with molecular chains from 8 to 18 carbons, including hydrogenated acids

Detergent alcohols are chemicals used as intermediates for Surfactants Production (e.g. alcohol ethoxylates, alcohol sulfates, alcohol ether sulfates) or as components in Personal Care and Household Products
Detergent alcohols can be classified as:Fatty Alcohols if derived from natural oilsSynthetic Alcohols if derived from oil and natural gas
Oxiteno is the major consumer of detergent alcohols inLatin America

Challenges
About the feedstock…
Supply from Malaysian and Indonesian suppliers
Storage capacity of 2.5 months for raw materials
RSPO – Roundtable on Sustainable Palm Oil
As Brazil presents the ideal conditions to produce Palm Kernel Oil, Oxiteno is a member of RSPO organization and it is concerned about developing alternative suppliers in Brazil.
A new plant requires new competencies and knowledge which need to be developed throughout the years.

Conclusion
To sum it up the challenges have been overcome and we are achieving a good level of knowledge on:
- How to operate the plant making the most of it;- How to manage vegetable feedstocks;- How to improve our sustainable portfolio;- Operation under fraction mode and manager by products
As a conclusion...
