A BSF factory in Central Thailand processing organic waste into insect protein meal (for aquafeed) and frass fertiliser. All figures below are working estimates — not confirmed data — and require field validation.

Critical gap (hypothesis): Current Phase 1 waste estimate (240k t) yields only ~11k t of meal — 55% of the 20k t target. Zones E (soy, +80k t) and F (fruit/veg, +60k t) must be sourced and contracted to close the gap. All volumes are assumed — field verification required.
ℹ
Key model inputs: BSF meal price $2,300/t · Frass $60/t · Capex $450k per 10 t/day capacity · Conversion rate 4.5% (fresh waste → dry meal) · Frass yield 25% of input. All are engineering assumptions, not market quotes.
⚠
What does not exist yet: No waste supply contracts, no aquafeed buyer commitments, no site selected, no regulatory approvals. This document is a structured hypothesis to guide engineering feasibility work.

A
Phase 1 — identified
BSG + distillery + starch pulp estimated
Bang Len / Sam Phran / Mueang · Nakhon Pathom · 0–20 km
Core of the proposed location. Three complementary streams in one corridor: brewery spent grain (BSG) from Singha, distillery solubles from Thai Alcohol, corn starch pulp from Sino-Thai Starch. High protein content, year-round availability. Estimated combined volume based on reported plant capacities.
Potential producers (not approached): Singha Beverage (Thailand's largest BSG source); Thai Alcohol Co. (ethanol / distillate); Sino-Thai Starch Co. (corn starch)

Nonthaburi → Suphan Buri · NW corridor · 40–80 km
Second BSG stream from TAPB Brewery (Bang Yai) combined with cassava pulp from Suphan Buri — one of Thailand's largest cassava-producing provinces. High-moisture substrate, well-suited to BSF. Volume estimated based on regional cassava starch output statistics.
Potential producers (not approached): TAPB Brewery (Thai Asia Pacific Brewery, Bang Yai); cassava starch mills of Suphan Buri

Ratchaburi → Kanchanaburi · W corridor · 60–110 km
Nongpho Ratchaburi Dairy Cooperative is Thailand's largest dairy coop (~800k L/day). Whey, wash water, and dairy returns are generated continuously. Thai Sugar Mill produces filter cake — a sugar- and fibre-rich substrate with good BSF conversion. Volume based on reported dairy throughput and sugarcane area statistics.

Food by-products / seasonal boosts estimated
Chachoengsao / Bang Pakong · E buffer · 130–160 km
Eastern Bangkok food industry cluster. Buffer zone for seasonal peaks — frozen fruit processing, prepared food returns. High competition for organic waste from existing biogas and compost operators in the area. Volume is speculative — the least certain of Phase 1 zones.

Phase 2 is the critical path to the 20k t meal target. Securing Zones E and F (estimated +140k t/yr) is required to reach the needed 444k t total. Neither soy crushers nor wholesale markets have been approached. Contracts are the primary risk.
E
Phase 2 — to source
Soy hull / okara estimated
Samut Prakan / Bangkok · Soy hub · 30–50 km
Thailand is Southeast Asia's largest soybean crusher. Four active plants (TVO, TVOP, Porn Amnuay Sup, Industrial Enterprise) process ~2.43M t/yr of soybeans. Soy hull and okara are low-value byproducts with minimal current monetisation — making them an attractive target. Volume estimated at ~3.5% of soybean crush as hull equivalent.
Potential suppliers (not approached): TVO — Thai Vegetable Oil (4 plants); TVOP — Thanakorn Vegetable Oil; Porn Amnuay Sup Vegetable Oil; Industrial Enterprise Co.

Fruit, vegetable & DC waste estimated
Bangkok / Pathum Thani · Wholesale markets · 40–60 km
Talat Thai is Thailand's largest wholesale produce market. Typical market waste is estimated at 5–15% of throughput. Central Fresh DC, Big-C and Makro distribution centres are additional sources. High sugar content substrate — fast BSF conversion cycle. Volume is a rough market-wide estimate; actual contractable volume per facility unknown.

G
Phase 3 — feasibility needed
Food-processing / ice cream / dairy estimated
Pathum Thani / Ayutthaya · 70–90 km
Concentration of large food manufacturers in the 70–90 km band. CP Foods, Nestlé, FrieslandCampina generate stable organic streams with high protein and fat content — better BSF conversion than starchy substrates. Volume based on reported plant throughputs and waste-to-output ratios from literature.
Potential suppliers (not approached): CP Foods Pathum Thani; Nestlé Thailand (multiple sites); FrieslandCampina Thai; Dutch Mill Group; ice cream plants in Ayutthaya

Cassava pulp — NE expansion estimated
Nakhon Ratchasima / Prachin Buri · 250–290 km
Largest single potential stream in the 300 km radius. Cassava pomace (wet pulp from starch extraction) is produced in massive volumes in NE Thailand. High moisture makes it difficult and expensive to transport over long distances. Two options to consider: haul wet pulp by tanker truck, or establish a satellite pre-drying / pre-processing unit in situ before transport.
Potential suppliers (not approached): Thai Tapioca Starch Association members; Chaiyaphum Starch Co.; Nakhon Ratchasima Tapioca Group; Prachin Buri starch cluster

Incomplete financial model. Gross payback ~1 yr is revenue ÷ capex only. A realistic IRR model must include: opex (energy, labour, maintenance, logistics ~$150–250/t), ramp-up timeline, working capital, regulatory costs, and realistic offtake pricing. Do not use gross payback for investment decisions.
06 / BSF Meal — Potential Buyers
Aquafeed market hypothesis
Potential buyers identified from public data. No approach, indication of interest, or price discussion has taken place. BSF meal must pass Thai DOF registration and buyer trials before commercial sale.

Suggested first step: Approach TFM (Mahachai, est. 70 km) with a small-scale MOU for a 200–500 t trial batch. This validates pricing, inclusion rate, and buyer willingness before committing to supply-side investment.
07 / Frass Fertiliser — Potential Buyers
Organic fertiliser market hypothesis
At Scenario 1, ~111,000 t/yr of frass is produced. Estimated realistic demand (P1+P2 segments): 32–51k t/yr. Remainder would need to go to bulk compost or aggregate distributors. Pricing estimates; no market quotes obtained.
🌾
Rice farming cooperatives
Suphan Buri · Ang Thong · Pathum Thani · 20–120 km
4M+ smallholder farms grow rice. 2024 fertiliser subsidy scheme (DoAE) covers purchase. Frass is high in organic carbon, reduces nitrogen leaching. Potential to generate T-VER (Thai voluntary carbon credits) for buyers. Volume estimate is regional — individual cooperative interest not tested.
15–25k t/yr
estimated demand
$40–60/t est.
🎋
Sugarcane — mills & farmers
Ratchaburi · Kanchanaburi · Suphan Buri · 30–120 km
~500k ha sugarcane in radius. Thai Sugar Mill is already in Zone C as a waste supplier — circular arrangement possible (take waste, sell frass back). EU biofuel sustainability requirements open organic premium niche. No commercial discussion has taken place.
8–15k t/yr
estimated demand
$50–70/t est.
🌺
Greenhouses & horticulture
Nakhon Pathom · Ratchaburi (Mae Klong) · 10–60 km
Orchids, chrysanthemums, tomatoes for Japan/EU export. Frass replaces expensive imported peat. High N/P/K + organic matter. Compatible with GlobalG.A.P. This is the nearest high-margin segment to the proposed site — suitable for an early pilot sale.
1–3k t/yr
estimated demand
$80–120/t est.
🥭
Organic export fruit
Ratchaburi · Nakhon Pathom · Samut Songkhram · 20–80 km
Durian, mangosteen, grapes for Japan and EU. Premium organic certification commands a price uplift. Frass from a BSF circular economy fits well with Japan's "mottainai" procurement narrative. Exporters Fruits of Siam and Thai Pride Produce are public — contact possible.
3–6k t/yr
estimated demand
$70–100/t est.
🥬
Cassava farming zones
Nakhon Ratchasima · Prachin Buri · 200–290 km
~200k ha cassava in radius. NE soils are organic-depleted. Trial data (literature) suggests +15–20% yield improvement with organic matter input. Circular scheme with Zone H: receive cassava pulp, return frass as soil amendment. Channel via Thai Tapioca Starch Association.
5–10k t/yr
estimated demand
$40–55/t est.
🦐
Aquaculture ponds
Chachoengsao · Nakhon Pathom · Ratchaburi · 10–150 km
Frass as phytoplankton biofertiliser in tilapia ponds. Replaces chicken manure without pathogens or odour. Double synergy: sell BSF meal and frass to the same farm. "One-stop shop" model for inland tilapia/shrimp operations. Demand is small but the relationship-building value is high.

estimated demand
$50–70/t est.
