Legume Integration - CAPEX, OPEX & Working Capital ?
Excellent — let’s quantify this properly.
Below is a DFI-style financial framework for:
(Per 1 Sub-Module = 2,000 rai)
Primary crop assumed: Organic Mung Bean
(You can later swap to sesame if needed — structure remains similar)
Important:
Legume integration is designed to be asset-light.
You should NOT build a new factory for legumes in Phase 1.
If you:
Use existing yard space
Use portable cleaners
Use manual/low-scale grading
Item
Estimated Cost (€)
Mobile seed cleaner / grader
60,000 – 90,000
Small drying platform / shed
40,000 – 70,000
Bagging + stitching line
25,000 – 40,000
Moisture meters & QA tools
10,000 – 15,000
Working shed / minor civil
50,000 – 80,000
€185,000 – €295,000
≈ 7–11 million THB
That is very small compared to rice cluster CAPEX.
You do NOT multiply by 8.
You centralize cleaning/drying.
Cluster-level legume CAPEX:
€350,000 – €500,000 total
Still modest.
Now we model per 2,000 rai.
Yield: 200 kg/rai
Total production: 400 tons
Price: 35 THB/kg (conservative organic)
Gross Revenue:
400,000 kg × 35 THB
= 14,000,000 THB
≈ €360,000

Total cost per rai ≈ 3,300 THB
Revenue per rai:
200 kg × 35 THB = 7,000 THB
Net ≈ 3,700 THB/rai
Very close to corn economics.

Total platform OPEX ≈ €125,000 / year
Legumes require less capital than rice.
Inventory holding: 2–3 months
Procurement at harvest (short season)
Working capital per sub-module:
~ €120,000 – €150,000
For full cluster:
~ €300,000 – €400,000
Much lower than rice.

Very healthy.
Legume integration:
✔ Prevents farmer exit
✔ Protects organic integrity
✔ Improves soil nitrogen
✔ Reduces fertilizer cost next rice season
✔ Improves ESG score
✔ Low capital intensity
✔ Fast payback
DFIs will view legume integration positively because:
It reduces monocrop risk
Improves soil health
Lowers water dependency
Improves farmer resilience
Demonstrates regenerative agriculture logic
It strengthens your investment thesis.
Legume Integration is:
Low CAPEX
Moderate margin
High ESG impact
High strategic value
It is a risk mitigation tool, not a side business.
