Feedstock
The answer is simple: right now.
Feedstock is a fundamental part of any waste or biomass value chain. Without it, there is no product at the other end.
Yet it is often treated as an assumption rather than a strategy.
The assumption tends to be that the feedstock will be there, accessible, affordable, available when you need it and in the right condition for the process.
Sometimes it is.
Often it isn’t.
Just because a feedstock exists doesn’t mean it is available to you.
The challenge may be physical, requiring collection, sorting or pre-processing infrastructure that does not yet exist. Or it may be commercial, with material already committed under long-term contracts or existing supply agreements.
Most waste already has a destination, whether that is recycling, landfill or energy recovery.
To divert it, you need a more attractive proposition.
Today’s low-cost feedstock can quickly become tomorrow’s scarce or expensive feedstock, particularly when multiple technologies are competing for the same material.
Waste is variable.
Chemical recycling may tolerate more contamination than some mechanical recycling processes, but economics and product quality still depend on understanding what is actually going into the process.
There are practical limits too. Too much of the wrong type of plastic can make pyrolysis oil difficult or uneconomic to sell. In tyre pyrolysis, maintaining a consistent tyre mix is important for producing a consistent product.
A pilot process that runs successfully on clean, single-source material demonstrates that the chemistry works.
It does not necessarily demonstrate that the process will perform reliably on the feedstock available at commercial scale.
Those are different claims, and the difference can become expensive if it is discovered too late.
Some projects, particularly in tyre pyrolysis and biomass, rely on imported feedstock to reach commercial scale.
That can create exposure to changing prices, availability, logistics and policy.
Feedstock therefore needs to be considered alongside the technology, not after it.
Too often, feedstock is reduced to a few assumptions in a financial model.
It deserves a strategy of its own.
Feedstock contracts should be treated with the same importance as offtake contracts. Test the assumptions, understand the alternatives and bring the right partners into the conversation before they become critical.
A strong feedstock strategy reduces project risk, strengthens the business case and provides greater confidence that the project can actually scale.
