What is needed to produce good paper?

IM is sitting on the terrace of his summer cottage. Sun is still high in southwest, seagulls are screaming -everything so peaceful.

And then the idea: what is needed to produce good paper?

First, people.

Those people who are interested in to drive a paper mill. All issues included - and there are many of them.

Price of wood; transportation of wood and other raw materials; services for the paper machines; 24 h driving of it....

In the beginning of his career, IM tend to visit control rooms of a paper machine during evening time. Sitting there, watching all the controls of the monitors, discussing about problems and how to cure them.

For some reason, microbiology has always been an interesting topic for personnel of a paper machine. What can happen to the raw materials? Can microbial activities cause problems in broke systems? How shall the water circulation and tanks be handled?

IM feels very humble today - to be one link in the complicated process called paper production.

One link - but as important as other links as well.

To understand the very multiscientific field of paper production - not to forget all activities to keep it on an economical satisfied level - is a hard task. What is needed (thinks IM) is to understand each other's work. It takes time to understand this truth - not your area only, but all efforts of others are needed to produce Good Paper.

Juha, you say "people" and that's a very interesting statement.

I have to admit my technology focus and orientation.

However, you're so right, it's people that are developing, building and running the machines.

The control room isn't all about automation. The final decisions are always made by people.

How many of us have forgot how the command control is organized.

Employers of a paper mill shall understand machines. But can it be also in a reversed way? Can machines be constructed so that they help people to notify when everything is not in order?

I think that modern automation can be (and already has been) planned to give "early warnings" when they notice hazardous situations in near future.

HACCP is a QC tool which should work as fast and reliable as possible. ON LINE monitoring and other novel techniques like PMEU fermentors can help the drivers of paper machines in this task significantly.

In the beginning, there should be a "human touch" beneath BIOTOUCH to agree and confirm all new adjutments of the processes which are recommended by BIOTOUCH methods. I think that learning processes for both personnel and BIOTOUCH methods are first needed.

These control methods can, howwever, work relatively independent in the future by performing decisions in complicated situations (like automatized controls in many vehicles). Human errors in stress situations may thus also be avoided.
