Years promising that broken eggshells might become something valuable.
Yet he'd died before proving it.
And now she was the one staring at the consequences.
She walked toward the machine shop.
Opened the door.
And switched on the light.
The room smelled of grease, dust, and old lumber.
Her father's tools hung above the workbench.
His coffee cup sat beside a stack of mechanical drawings.
And beneath the bench was the cardboard box he'd mentioned in the hospital.
She crouched.
Pulled it out.
Then sat on the concrete floor.
For several seconds, she couldn't open it.
Her hands were shaking.
Finally, she lifted the lid.
Inside were three plastic containers holding cleaned eggshell samples, several photographs, a bundle of letters, and a thick black notebook.
Across the notebook's cover, in her father's familiar handwriting, were four words.
Stop wasting the calcium.
She laughed bitterly.
“Dad, seriously?”
Tears filled her eyes.
She lifted the notebook.
The first pages contained sketches of the old packing shed.
Equipment layouts.
Estimated processing costs.
Notes about airflow, moisture, and dust collection.
Then came calculations.
Eggshell supply volumes.
Drying energy.
Grinding capacity.
Transportation costs.
Packaging options.
Labor.
Maintenance.
And potential sales prices for different quality grades.
She stared.
These weren't the random notes of a man collecting garbage because he liked strange ideas.
They were the beginnings of a genuine feasibility study.
Her father had spoken with three regional egg-breaking facilities.
He'd identified processors paying commercial companies to handle shell waste.
He'd contacted laboratories about material characterization.
And he'd requested equipment quotations from several manufacturers.
The young woman turned another page.
A letter fell out.
It came from a materials engineering company in Oregon.
The author thanked her father for submitting an eggshell sample and explained that the calcium carbonate content appeared promising for certain nonfood industrial applications, subject to further testing and processing.
The letter didn't promise a purchase.
It didn't declare the material revolutionary.
But it identified several specifications a potential supplier would need to meet.
Particle size.
Moisture.
Organic contamination.
Mineral composition.
Batch consistency.
And traceability.
She read the letter twice.
Then continued.
Another document contained a proposed design for a small cleaning and drying line.
A third described a pilot grinding system.
And near the back of the notebook, her father had written a page titled:
What Could Go Wrong.
She smiled despite herself.
There were nearly twenty entries.
High transportation costs.
Wet raw material.
Variable shell quality.
Excessive energy use.
Mechanical breakdowns.
Inadequate sanitation.
Dust exposure.
Insufficient buyers.
Permitting difficulties.
Working capital shortages.
And the risk that existing mineral suppliers could undercut any premium she hoped to charge.
