we’re dealing with lignin and other solid<br />

fuels.”<br />

“The infrastructure that exists at<br />

Bäckhammar offers great opportunities<br />

for extending its operations.” continues<br />

Niklas. “One approach is the utilisation<br />

of sulphur-free pre-treatment to separate<br />

the carbohydrates from the lignin<br />

and then further refine the carbohydrates<br />

into basic sugars. This opens the<br />

door to several possibilities for producing<br />

various specialty products, such as<br />

ethanol and lactic acid that can be used<br />

for making Polylactic Acid (PLA). Then<br />

you also have access to a very pure,<br />

sulphur-free lignin.”<br />

Another interesting route involves the<br />

purification of methanol, which could be<br />

used as a fuel or a chemical.<br />

“The studies being carried out<br />

today are on a laboratory scale but, at<br />

Bäckhammar, we can leave behind the<br />

test tube and work on a significantly<br />

larger scale.”<br />

A flexible plant<br />

makes demands<br />

on creativity<br />

and problem<br />

solving<br />

Every day presents new challenges. When<br />

the employees arrive in the morning,<br />

there might be a couple of boxes with<br />

equipment, waiting to be assembled for<br />

a trial on the following day. Instructions<br />

or diagrams do not always ac<strong>com</strong>pany<br />

them, so it is a question of the employees<br />

being inventive and <strong>com</strong>ing up with<br />

solutions of their own.<br />

“Due to the fact that new processes<br />

are constantly being developed and different<br />

equipment is being tested, you<br />

always have to learn new things. But,<br />

Leif Swärd and Jan Bernhardsson.<br />

Carina Nordberg, Jan Emilsson and Stefan Andersson in the control room.<br />

we have a green light for our own ideas.<br />

We are given a task that has to be solved<br />

some way or another. An example of<br />

this is the Metso press filter used for<br />

washing of the lignin. You can’t find<br />

one in this application anywhere else,<br />

just here. So we simply had to teach<br />

ourselves,” explain Leif Swärd and Jan<br />

Bernhardsson, two of the operators at<br />

Bäckhammar.<br />

Working as an operator in the industry<br />

usually means being responsible for<br />

a particular step in a process and no<br />

more. At the Bäckhammar demonstration<br />

plant, such a job looks different. It<br />

involves a more <strong>com</strong>prehensive responsibility<br />

for everything, from loading and<br />

unloading to working in a laboratory.<br />

“This means that our work has more<br />

variety and we’re independent. You feel<br />

more responsible when you’re part of<br />

things and plan everything,” <strong>com</strong>ment<br />

Carina Nordberg and Stefan Andersson<br />

in the control room.<br />

The manager of the plant at<br />

Bäckhammar is Jan Emilsson. He directs<br />

all the different assignments that <strong>com</strong>e<br />

from Project Managers at <strong>Innventia</strong> and<br />

from the industry.<br />

“This kind of industrial collaboration<br />

is very important. Many of the<br />

assignments are really exciting ones, for<br />

instance, the collaboration we have with<br />

Akzo Nobel on the continuous production<br />

of a liquid lignin product.”<br />

All of the operators have been there<br />

since the start, when LignoTech began<br />

producing lignin at Bäckhammar in<br />

1994. Per Tomani, who was the Project<br />

Manager and responsible for the investment<br />

project, when the old “LignoTech<br />

Process” was expanded into the<br />

LignoBoost Process (a demonstration on<br />

a large scale, which could be said to have<br />

been most unusual for an R&D <strong>com</strong>pany,<br />

such as <strong>Innventia</strong>), says that this has<br />

been a great source of assurance.<br />

“The people here are so terrifically<br />

gifted and skilled. They know the Plant<br />

inside and out. It’s such a wonderful<br />

experience working with them.”<br />

<strong>Innventia</strong>s demonstrationsfabrik<br />

i Bäckhammar är så nära den<br />

industriella verkligheten man kan komma.<br />

Här finns all nödvändig infrastruktur med<br />

tankar, pumpar, ånga, kylvatten. Genom<br />

att köra kontinuerligt under längre perioder<br />

får man tid att upptäcka eventuella fel<br />

som kan uppstå i industrin. Produktionen<br />

kan anpassas enligt önskemål och man<br />

utnyttjar svartlut från flera bruk. Många<br />

av de pågående projekten är knutna till<br />

det pågående LignoFuel-programmet och<br />

till <strong>Innventia</strong>s kluster ”Energy & Biofuels”.<br />

Här produceras också det lignin med hög<br />

renhet som används i forskningen för att<br />

framställa kolfiber.<br />

Fabriken sysselsätter fem personer. Att<br />

arbeta som operatör i industrin innebär<br />

vanligen att ha ansvar inom ett begränsat<br />

processteg. På fabriken i Bäckhammar ser<br />

rollen annorlunda ut, mer övergripande<br />

med ansvar för allt, från in- och utlastning<br />

till arbete i labb.<br />
