Rapeseed, sunflower and palm oil are popular renewable raw m<strong>at</strong>erials for <strong>the</strong> production of bio-lubricants. For modern high-performance lubricants, however,<br />

<strong>the</strong>y are transformed into syn<strong>the</strong>tic esters.<br />

called “technical report”, which, after<br />

being supplemented and optimized,<br />

will form <strong>the</strong> basis for “technical specific<strong>at</strong>ions”<br />

one year l<strong>at</strong>er. From <strong>the</strong>se<br />

technical specifi c<strong>at</strong>ions a standard will<br />

be derived which will be binding for all<br />

EU-member st<strong>at</strong>es.<br />

“The definition we have developed will<br />

stipul<strong>at</strong>e <strong>the</strong> minimum requirements<br />

for all types of bio-lubricants“, explains<br />

Rolf Lu<strong>the</strong>r. In focus are bio-degradability,<br />

content of renewable resources,<br />

toxicity and performance. “For <strong>the</strong><br />

longest time since <strong>the</strong> 1970s, <strong>the</strong> most<br />

important criterion for a bio-lubricant<br />

was degradability”, <strong>the</strong> physicist<br />

remembers. “In particular oil losses due<br />

to engine design, such as on outboard<br />

bo<strong>at</strong> engines or saw chains, causing<br />

unpleasant oil spills on <strong>the</strong> w<strong>at</strong>er surface<br />

or in <strong>the</strong> forest, de manded quick<br />

degradability. Today, consumers also<br />

associ<strong>at</strong>e bio-lubricants with renewable<br />

resources.“ He assumes th<strong>at</strong> <strong>the</strong><br />

task force will recommend a minimum<br />

proportion of 25% renewable resources<br />

in use of <strong>the</strong> m<strong>at</strong>erial itself. Th<strong>at</strong><br />

would be a feasible compromise meeting<br />

consumer expect<strong>at</strong>ions and not discrimin<strong>at</strong>ing<br />

<strong>ag</strong>ainst petrochemical products.<br />

“Where bio-degradability is concerned,<br />

OECD Directives (Test Pro cedure<br />

OECD 301) apply which require a degrad<strong>at</strong>ion<br />

of <strong>at</strong> least 60% for oils and<br />

minimum 50% for lubricants within 28<br />

days. Radiocarbon d<strong>at</strong>ing is used as <strong>the</strong><br />

method to identify <strong>the</strong> content of re -<br />

newable resource – usually a method<br />

to determine <strong>the</strong> <strong>ag</strong>e of organic m<strong>at</strong>e-<br />

rial but also suitable to classify raw<br />

m<strong>at</strong>erials. “I place particular importance<br />

on customer orient<strong>at</strong>ion: <strong>the</strong> end<br />

consumer can verify each criterion on<br />

<strong>the</strong> final product.“ This is essential<br />

when trying to engrain a good reput<strong>at</strong>ion<br />

of bio-lubricants in <strong>the</strong> mind of<br />

<strong>the</strong> customer.<br />

As far as possible, <strong>the</strong> new standard<br />

should also be comp<strong>at</strong>ible with <strong>the</strong><br />

“Marguerite”, <strong>the</strong> EU ecolabel for<br />

lubricants (EEL) in force for lubricants<br />

since 2005. “In <strong>the</strong> beginning, this ecolabel<br />

was not <strong>at</strong> all accepted by <strong>the</strong><br />

market. It is simply not as widely known<br />

as <strong>the</strong> Blue Angel, <strong>the</strong> German environmental<br />

label. Since 2008, however,<br />

increasingly more biodegradable<br />

hydraulic oils are on <strong>the</strong> market, and so<br />

is <strong>FUCHS</strong> with its ENVIRO product<br />

range”, says Lu<strong>the</strong>r. But why is <strong>the</strong> EEL<br />

not taken as criterion for a bio-lubricant?<br />

“The reason is quite simple: <strong>the</strong><br />

ecolabel is awarded only for product<br />

groups, and currently <strong>the</strong>re are only<br />

very few product ranges. The Marguerite,<br />

for example, is awarded for<br />

hydraulic oils, but not for engine oils or<br />

metalworking fluids. Th<strong>at</strong> is why a<br />

comprehensive definition for bio-lubricants<br />

is so important.”<br />

Syn<strong>the</strong>tic esters in use<br />

For <strong>the</strong> production of bio-lubricants,<br />

preferably vegetable oils and animal<br />

f<strong>at</strong>s are used as renewable raw m<strong>at</strong>erials<br />

– in Germany <strong>the</strong> most common<br />

choice is rapeseed oil. Although n<strong>at</strong>ive<br />

vegetable oils have good lubric<strong>at</strong>ion<br />

properties – for high-performance oils<br />

<strong>the</strong>y are hardly ever used in unchanged<br />

composition. Through chemical modific<strong>at</strong>ions,<br />

vegetable oils are transformed<br />

into syn<strong>the</strong>tic esters – a process comparable<br />

to petrochemical refining, producing<br />

modern hydrocarbon base oils<br />

from crude oil by means of more or less<br />

complex processes. In <strong>the</strong> form of such<br />

syn<strong>the</strong>tic esters, high-performance<br />

lubricants can be produced from vegetable<br />

oils which are equal or even superior<br />

to mineral oil-based lubricants. The<br />

objective is to conserve <strong>the</strong> good properties<br />

of vegetable oils (good environmental<br />

comp<strong>at</strong>ibility, good lubric<strong>at</strong>ing<br />

properties) and improve <strong>the</strong> critical<br />

properties (lack of low-temper<strong>at</strong>ure<br />

stability, tendency to oxid<strong>at</strong>ion and<br />

hydrolysis).<br />

From a clearly defined standard for<br />

bio-lubricants, Rolf Lu<strong>the</strong>r expects an<br />

impetus for this market, which would<br />

also benefit <strong>FUCHS</strong>. “We are an independent<br />

lubricant manufacturer th<strong>at</strong><br />

does not own oil wells“, he outlines<br />

<strong>the</strong> perspective. “We can use <strong>the</strong> most<br />

diverse raw m<strong>at</strong>erials, develop altern<strong>at</strong>ive<br />

products and benefit from new<br />

market opportunities.” But also in<br />

terms of an efficient and profitable<br />

bio-lubricant development, EU-wide<br />

applicable standards make perfect<br />

sense: “Th<strong>at</strong> way, we can market standardized<br />

products in EU countries and<br />

do not have to observe <strong>the</strong> regul<strong>at</strong>ions<br />

of each individual country.”<br />
