Lesson 19 of 20 · Chapter 19
Sustainability, Green Manufacturing, and TPM
Carbon sounds like a job for the utilities team or the finance office. This chapter says it is mostly the same losses TPM has been chasing all along, measured in a different unit. A machine that idles hot, leaks air, or makes scrap is wasting energy and material as well as time. Fix the loss, prove the fix, and the carbon comes down with it, without lowering safety or quality to get there.

Part 1
Energy per good unit, not energy per month
Most plants treat energy like rent: a fixed bill, paid every month. TPM treats it like quality: something the machine can do well or badly.
So measure energy per good unit, not the monthly total. The monthly total “improves” if you simply make less, which is not an improvement at all.
The most wasteful minutes are rarely steady running. They are start-ups, idling, stops and restarts: energy burned while no good product is made.
Much of the “carbon problem” is simply the six big losses expressed in environmental units: extra heater cycling, more compressed air, longer dwell times, more reject handling, more short stops. Energy can have normal bands by operating state, just like vibration or current in Chapter 12.
The same closure pipeline does the work: detect abnormal energy use early, route it to an owner, intervene in a governed window, verify the baseline was restored, and capture the learning.
“In most plants, energy is allocated like rent, not managed like quality.”
“TPM flips that by insisting on unit-level thinking: energy per good part, not energy per month.”
“The most carbon-intensive minutes of a line’s day are often not steady-state production.”
“Carbon neutrality becomes less mysterious when you realize that much of the “carbon problem” is simply the six big losses expressed in environmental units.”

One day on a sealing station. Try three ways to “cut energy” and compare total kWh with energy per good unit. The day is an illustration; every number is calculated.
Part 2
Every pillar already cuts carbon
Carbon work does not need a separate programme. The TPM pillars already do it.
Autonomous maintenance: operators tag air leaks and idle modes on their route. Focused improvement: a team kills the stop cascade that wastes energy with every restart. Early equipment management: the next machine is bought with a true standby mode.
And planned maintenance closes a job only when energy is back in its normal band, not just when the machine runs.
Autonomous maintenance becomes a carbon tool immediately, because many energy losses are basic-condition failures hiding in plain sight. Focused improvement is the accelerator, because chronic waste sits between functions. Early equipment management asks whether new equipment can truly cut consumption during stops, rather than just changing the colour of a status light.
Some reductions will come from sourcing, electrification and process redesign beyond maintenance. But switching to renewable electricity without fixing chronic scrap simply produces green scrap. A plant must first prove it can hold normal.
“Autonomous Maintenance becomes a carbon tool immediately because many energy losses are basic-condition failures hiding in plain sight.”
“If your closure package cannot show that energy returned to normal, you did not restore normal; you restored function.”
“Switching to renewable electricity without fixing chronic scrap simply produces green scrap.”
Six carbon actions. Which TPM pillar does each one belong to?
Part 3
Remove the loss, never lower the standard
Energy Kaizen is focused improvement aimed at resources: electricity, compressed air, steam, water and material.
It starts with the obvious waste: air leaks are pure loss, and they teach the habit fast. Then it moves to the costly kind: waste during start-ups, changeovers and repeated small stops.
Two rules. Never cut energy by lowering a standard (a shorter warm-up, less ventilation). And never just move the loss: a standby mode that saves power but makes scrap on restart is no gain.
A good event is short and evidence-driven: baseline by operating state (air flow when stopped for a fault versus waiting, kWh per good unit in warm-up versus steady state), countermeasures, then verification that the saving persists, which is where most energy programmes fail.
Blame breaks it. If leaders use energy dashboards to accuse shifts of “wasting power,” people stop telling the truth, bypass sensors and avoid tagging leaks. Abnormal resource use is a system problem to be designed out.
“Compressed air leaks are the classic example because they are pure loss, and they teach the mindset quickly.”
“You shifted loss from one bucket to another, and modern TPM refuses those trades.”
“Safety remains non-negotiable, quality remains at the source, and energy improvement must be achieved by removing loss mechanisms, not by lowering standards.”
“Energy Kaizen works only when the organization treats abnormal resource use as a system problem to be designed out, not as a character flaw to be punished.”
Three energy ideas on the table. Which would the chapter accept?
Part 4
A good asset turned bad before its time
The circular economy means keeping parts and materials in use: reuse, repair, remanufacture, recycle.
In a TPM plant it starts with a simple idea of waste: a good part turned into a bad part before its time.
A bearing replaced too early is waste. A bearing replaced too late is also waste, often taking the shaft and housing with it. And scrap kept sorted by material can come back as feedstock instead of going to landfill.
Circular systems fail when people cannot trust what something has been through. To reuse or remanufacture a component, you need its history: was it overloaded, overheated, run outside its envelope, or kept alive through compensation? That is the same verified, recorded closure the plant already runs.
Scrap is also a broken loop. The best circular move is intervening in a governed window so material never becomes scrap; the next is segregating it by material and condition so clean scrap becomes higher-value feedstock. Procurement joins in through return-to-stock rules and take-back or remanufactured options judged on evidence.
“The easiest way to connect circular economy principles to TPM is to start with the most unforgiving definition of waste: a good asset turned into a bad asset before its time.”
“A bearing replaced too early is waste.”
“Scrap that is segregated by material and condition can become a higher-value feedstock.”
Six decisions about parts and scrap. Which keep things in use, and which are linear waste?
Part 5
Normal now includes energy
The plant does not “add” a carbon programme. It extends the definition of normal.
A line is not “running” if it is bleeding energy while idle. A repair is not “done” if energy did not return to baseline. A change is not an “improvement” if it cuts carbon by creating a safety or quality risk.
The bench below puts it together on one day at the sealing station.
Daily huddles treat abnormal energy events like any other abnormality: log, triage, act. Weekly cross-functional reviews segment energy intensity by operating state and tie the biggest deltas to loss mechanisms and countermeasures.
Done with TPM rigour, Energy Kaizen stops being a special event and becomes a habit of seeing: operators notice air leaks and idle modes that misbehave, maintenance treats energy as part of “back in control,” and leaders fund design-level fixes because the evidence is verified.
“The plant does not “add” a carbon program; it extends the definition of normal.”
“A line is not “running” if it is bleeding energy in idle states.”
“A restoration is not “done” if energy intensity did not return to baseline.”
“When Energy Kaizen is done with TPM rigor, it stops being a special event and becomes a habit of seeing.”
The Energy-per-Good-Unit Bench. Set the day, then choose how the station is run and managed. Energy per good unit is calculated from every choice. The numbers are an illustration.
Part 6
Try it where you work
Do these on a real machine: at work if you work with equipment, or at home on a car, washing machine, furnace or lawn mower if you do not. Tick each one when it is done. Safety first: look and clean only what you are allowed to touch, never reach into moving equipment, and follow your site’s lockout rules.

Global Sovereign University · Modern TPM, lesson 19
Green by closure
- Energy per good unit, not per month.
- Carbon is the six big losses in other units.
- Tag leaks on the route; close them.
- Never lower a standard to cut energy.
- Do not shift loss from one bucket to another.
- Replace on condition; segregate scrap.
Normal now includes energy. A repair is not done until energy is back in band.
