You may think we are always talking about new machine installations here at the Light Green Machine Institute.
We are not.
We are talking about your machine, your pulp mill, or whatever operations you are in charge of today.
How do you make them Light Green Machines?
Monitor the unit operations under your purview. If you have unit ops that are operated only occasionally, or perhaps never at all, you have found a way to make your operations lighter. Take them out, and take out all the piping, wiring, controls and logic schemes in your software, too.
Do a rigorous audit and you will be amazed how much equipment you have installed that does nothing but take up space and create liabilities of all sorts (from safety to downtime to maintenance and beyond).
Over the years, many, many unit operations are installed in pulp and paper mills that either did not live up to their promises or became obsolete. They still occupy real estate and sit there as ticking time bombs, ready to blow up on you in an unforeseen way. Take them out now.
