“The Wrong Question” Part 5/6
“Is there enough waste?” is the wrong question.
01 · The frame
Enough waste is not a feedstock
A spreadsheet can show a large volume of organic material near a proposed BSF facility. That is useful. It is not yet a feedstock — and it is definitely not yet a business case.
The right question is:
Is this stream biologically suitable, commercially accessible, legal for the intended product route and genuinely unwanted?
02 · Two screens
Two assessments, kept separate
When I screen a stream, I keep two assessments separate.
First: can larvae use it reliably?
I look at four things:
- seasonal reliability
- nutritional suitability
- moisture
- hazard probability
Second: can the operator secure and handle it economically?
I look at five different things:
- purity
- competing demand
- price
- contract security
- procurement and logistics
I never add those two scores together.
03 · Tonnage
Abundance is not quality
A stream can be abundant, free and delivered — but nutritionally poor or contaminated.
Another can be an excellent substrate — but already sold as feed, contracted to a biogas plant or too dispersed to collect economically.
Daily tonnage is recorded separately. It sets the potential scale. It does not set quality.
Mixing tonnage into a quality score is how a large dirty stream gets mistaken for a good one.
04 · The hard gate
Law decides the product route
Then comes the hard gate: law.
The fact that larvae can eat a material does not mean the resulting product can legally enter the intended feed, food or fertiliser route. That decision depends on the substrate, jurisdiction and end use. Biology does not cure a regulatory failure.
05 · The counterfactual
Where does the material go today?
Finally, “waste” needs a counterfactual.
Where does the material go today? Is it already fed, composted, digested, sold or collected under an existing contract? What does that route cost, and why would the owner change it?
If there is already a productive outlet, BSF must beat that real alternative. It cannot claim the material as newly diverted by default.
06 · The decision
A “no” is a useful decision
This screening can produce a “no.” That is not a failed project.
It is a useful decision made before equipment, permits and capital are committed. A weak stream may need blending. An inaccessible stream may need a contract. An illegal route needs a different output plan — or a walk-away decision.
Characterise the stream first. Design the facility second.
What productive use already exists for the material you are calling waste — and what would a BSF case have to beat?
