Biochar Field

What is actually left after harvest?

The opportunity starts with residue that is genuinely available, can be converted consistently and creates enough value in the field to earn repeat use.

Pabna · agricultural context

Scale is visible. Supply decides the case.

Pabna's crop base makes it a practical place to test feedstock supply, logistics and farmer demand.

Maize≈10,239 t2024–25 production

Feedstock case

Abundance is not availability.

A viable feedstock needs reliable seasonal volume, workable condition and a delivered cost that holds without displacing better existing uses.

Existing useWhat is it used for now?
Existing valueWho already pays for it?
Seasonal volumeHow much can actually be collected?
ConditionMoisture, ash and contamination.
Delivered costCollection, preprocessing and haul radius.

The best feedstock is genuinely surplus and economical to collect.

Batch evidence

What does one batch need to prove?

Four questions shape the investment case.

SourceIs it really available?
Source

Is it really available?

  • Current use and existing value
  • Ownership and seasonal volume
  • Condition and delivered collection cost
  • Traceable source

A viable supply needs traceable ownership, usable volume and a delivered cost that works.

Field + market evidence

Does it work in the field and in the market?

Field response and delivered application cost determine whether the product earns repeat use.

Investment questionDoes the response justify what it costs to buy, move and apply the material?
Product economics

Physical economics first. Carbon upside second.

That cost is tested against willingness to pay, repeat demand or a credible offtake route.

What development funding buys

From diligence to operating evidence.

Funding covers the work needed to identify viable feedstock, confirm the site, select equipment and test demand before scale.

Development fundingBuild the investment case.
  1. Feedstock pack

    Available volume, competing use and delivered cost.

  2. Site + approvals pack

    Preferred site, fallback and clearance path.

  3. Procurement pack

    Comparable equipment offers and recommendation.

  4. Proof pack

    Field protocol, prospective users and carbon pre-screen.

If the case supports investment

Operating evidenceBuild a track record for scale.
  1. Commissioned line

    Controlled production with safety and batch records.

  2. Operating record

    One season of feedstock, process and yield evidence.

  3. Field + market evidence

    Application cost, field response and repeat demand.

  4. Scale decision pack

    A clear recommendation on whether and how to scale.

Investment conditions

What has to be true for scale?

  • Feedstock is genuinely surplus and economical to collect.
  • The site clears environmental and operating requirements.
  • Equipment meets safety and emissions standards.
  • Field response justifies delivered application cost.
  • Users show repeat demand.
  • Any carbon claim meets the chosen methodology.
