Peliyagoda & Manning Market · Colombo

Market waste becomes market value.

BioNova is a Black Soldier Fly bioconversion facility that intercepts fish and vegetable waste from Colombo's two busiest markets before it reaches a landfill — and turns it into protein feed and organic fertiliser instead.

01 — The Problem

Two markets, one landfill, no plan.

Peliyagoda and Manning together generate 15–20 metric tons of organic waste daily. Almost all of it is currently trucked to Karadiyana or Meethotamulla, generating methane, leachate, and mounting collection costs along the way.

Peliyagoda Fish Market

Sri Lanka's largest wholesale fish market — 200+ tonnes of fish handled daily at peak season
Fish offal & entrails1.5–2.0 MT
Fish heads & frames0.8–1.2 MT
Spoiled / rejected fish0.5–0.8 MT
Scales & skin0.3–0.5 MT

Manning Market

One of Colombo's principal vegetable and fruit wholesale hubs — trading 24 hours a day, 7 days a week
Vegetable trimmings & peels4.0–5.5 MT
Spoiled / unsaleable produce2.5–3.5 MT
Fruit waste & rinds1.5–2.5 MT
02 — The Process

How the Black Soldier Fly does the work.

Hermetia illucens larvae consume organic waste 50–70x faster than conventional composting. Colombo's climate — 27–32°C — sits almost exactly inside their optimal growth range.

STAGE 1

Reception & blending

Waste is weighed, sorted, shredded to under 5cm, and blended fish-to-vegetable at a 1:3 ratio for the optimal C:N balance.

STAGE 2

Larval rearing

Neonates hatch in 3–5 days, feed on starter vegetable matter, then move onto blended feedstock for 10–14 days of bioconversion.

STAGE 3

Self-harvesting

Mature prepupae migrate out of feeding bins on their own via exit ramps, and are collected automatically — no manual sorting needed.

STAGE 4

Two products, one input

Prepupae are screened, dried or sold fresh; residual frass is dried and packaged as certified organic fertiliser.

03 — The Output

Waste in. Two saleable products out.

Animal Feed Ingredient

BSF Prepupae

A protein-rich alternative to fishmeal for the aquaculture and poultry sectors, sold fresh or dried.

  • Crude protein35–45% DW
  • Crude fat25–35% DW
  • Projected output600–800 kg/day
  • Annual revenueLKR 77.8M
Organic Soil Amendment

Frass Fertiliser

A nutrient-dense byproduct that meets SLS 1247 organic fertiliser standards and offsets synthetic NPK use.

  • Nitrogen (N)2.0–3.5%
  • Projected output500–700 kg/day
  • Yield lift observed20–35%
  • Annual revenueLKR 12.0M
04 — The Case

The economics and the environment, side by side.

A 5 MT/day pilot facility pencils out at a modest capital outlay with an EBITDA margin near 84% once at steady state.

05 — The Path

From permit to full commercial scale.

0
Months 1–3

Pre-implementation

EIA clearance, land lease, permitting, and MoUs with market administrators for a consistent waste supply.

1
Months 3–18

Pilot operations

Construction, staff training, and scale-up from 1 to 5 MT/day, alongside market development for prepupae and frass.

2
Months 18–36

Scale-up

Additional rearing capacity brings the facility to 10 MT/day as demand for both products grows.

3
Months 36–60

Full commercial scale

15+ MT/day capacity, with potential third-party waste intake from beyond the two founding markets.

BioNova is being developed in consultation with Puravaduma BSF (Pvt) Ltd, Peliyagoda and Manning market management, the Peliyagoda Urban Council, and the Urban Development Authority. If you represent a market, a farm, or a financing partner, we'd like to talk.
