Waste-based microbial oil set to become a raw material for renewable diesel
Neste Oil has applied for patents to cover technology developed to produce
microbial oil from waste and residues with the help of various yeasts and molds
for use as a feedstock for its NExBTL renewable diesel. Research work started
with the Aalto University School of Science and Technology at the end of 2007
has resolved the process technology-related challenges involved; and microbial
oil produced in this way has already been successfully refined into NExBTL
renewable diesel.
"Our research is currently concentrating on ways of extending the range of raw
materials we can use for producing NExBTL, and we're particularly focusing on
nonfood materials capable of making a significant contribution to reducing
greenhouse gas emissions," explains Neste Oil's Biotechnology Manager, Markku
Patajoki.
"Our work has shown that waste-based microbial oil represents an excellent
opportunity, and we believe it's a very promising future raw material."
Following the success of the lab work, the emphasis will now shift to evaluating
microbial oil's potential for pilot-scale production. Commercial production is
likely to be possible by 2015 at the earliest.
Making use of agricultural and industrial waste and residues
Research has shown that agricultural residues, together with waste and
sidestreams from industry, represent an excellent source of energy and carbon
for yeasts and molds, which feed off organic compounds.
"Sugars from cereals and sugar cane can also be used, but agricultural and
industrial waste and residues are even more interesting materials from a
sustainable point of view," says Neste Oil Researcher Perttu Koskinen.
"We're currently in the process of evaluating a number of alternative raw
materials for processing using yeasts and moulds. Agricultural residues such as
straw or an industrial by-product such as glycerol from traditional biodiesel
process, for example, are suitable for producing microbial oil using yeasts or
molds."
New innovations call for advanced applied scientific research
Finland is a world leader in microbial oil research, and the work carried out by
the Aalto University School of Science and Technology and Neste Oil is at the
cutting edge of the field. The School of Science and Technology concentrated on
the initial phase of identifying which yeast and mold strains are the most
suitable for industrial use and developing the systems technology needed to
ensure that microbes generate sufficient levels of oil. Neste Oil, for its part,
focused on leveraging its expertise to extract the microbial oil produced from
the biomass.
"Collaboration with Neste Oil on the project has gone very well," says Professor
Simo Laakso of the Department of Biotechnology and Chemistry at Aalto
University.
"We've been able to draw on our know-how in the scientific fundamentals to
identify new sources of raw materials for producing renewable fuels. This kind
of applied scientific research is essential for generating new innovations that
can go on to be commercialized."
Neste Oil has a long history in developing cleaner, lower-emission traffic
fuels. The company currently spends close to ?40 million annually on R&D, of
which around 80% is linked to renewable raw materials. In addition to microbes,
Neste Oil is also investigating the potential of algae, jatropha, forest
industry by-products, and other materials.
NExBTL technology is very flexible and can be used to produce renewable diesel
from different types of raw materials, such as vegetable oil and waste fat from
food industry. NExBTL renewable diesel is currently produced from palm oil and
rapeseed oil and waste fat sourced from the food industry.

Storebrand, and is on Innovest's Global 100 list of the world's most sustainable
corporations. Forest Footprint Disclosure (FFD) has ranked Neste Oil as the best
performer in the oil & gas sector. Further information: www.nesteoil.com.
NExBTL renewable diesel in brief
Neste Oil's NExBTL renewable diesel is compatible with all diesel engines and
can be used as such or blended with fossil diesel. It has an identical chemical
composition to that of fossil diesel and offers equally good or superior product
properties. NExBTL renewable diesel has been tested extensively and successfully
in trucks, buses, and cars around the world. Neste Oil supplies the Finnish
market with Neste Green diesel, which contains a minimum of 10% renewable
content.
