Commercial Vermiculture & Earthworm Castings Organic Fertilizer Plant

East Nusa Tenggara’s semi-arid agricultural soils suffer from chronic low organic matter and nutrient depletion due to prolonged dry seasons and excessive chemical fertilizer application. At the same time, regional cattle feedlots, abattoirs, and agro-processors generate immense quantities of livestock manure, corn cobs, and organic residues. This enterprise establishes an industrial-scale vermiculture (earthworm composting) facility in KIB utilizing African Nightcrawler (Eudrilus eugeniae) and Red Wiggler (Eisenia foetida) earthworms. The facility produces organic vermicompost castings (Kascing) rich in plant-available humic acids, beneficial microbes, and natural growth hormones, supplying regional horticulture, dragon fruit, and vegetable growers.

Products & Business Formats

Premium Screened Earthworm Castings (Kascing Vermicompost)

Fine, dark, odorless organic vermicompost packed with humic acids, beneficial microbes, and balanced macro/micronutrients for horticulture.

Liquid Vermi-Extract & Earthworm Bio-Stimulant Spray

Cold-extracted liquid organic fertilizer and biological foliar spray rich in natural plant hormones (auxins, gibberellins) for fruit and vegetable crops.

Live Commercial Breeder Earthworms (Eisenia foetida & Eudrilus eugeniae)

Certified live earthworm biomass and starter breeding colonies sold to agricultural cooperatives, community groups, and educational farms.

Dry Earthworm Meal for High-End Aquaculture & Poultry Feeds

Oven-dried and pulverized whole earthworm powder (65%–70% crude protein, high lysine content) for premium ornamental fish and shrimp feeds.

Business model

Revenue is based on solid vermicompost sales in 5 kg and 25 kg bags and bulk tonnage, bottled/jerrycan liquid fertiliser sales, live-worm biomass sales per kilogram, and dried-worm meal exports.

Development stages

1. Stage 1 — Build a screening, solar-dome drying, and packaging centre for 500 tonnes/year of vermicompost at KIB Bolok in partnership with 20 local farmers.
2. Stage 2 — Register organic-fertiliser distribution permits with Kementan and expand distribution through agricultural-store networks throughout NTT.
3. Stage 3 — Install freeze dryers or vacuum dryers to produce pure worm meal meeting pharmaceutical/feed export standards.

East Nusa Tenggara’s semi-arid agricultural soils suffer from severe organic depletion and high salinity due to prolonged dry seasons and excessive chemical fertilizer use. Simultaneously, commercial cattle abattoirs, feedlots, and agricultural processing hubs in Greater Kupang generate vast volumes of livestock manure and organic waste that lack proper treatment. Sourcing local manure and crop residues, this vermiculture facility in KIB transforms agricultural wastes into certified organic vermicompost (Kascing).

Market Demand & Potential Buyers

• Commercial horticulture, dragon fruit, and specialty vegetable growers across Timor and Flores
• Provincial government agricultural soil rehabilitation and reforestation programs in NTT
• Urban landscaping, commercial nurseries, and home gardening markets throughout Greater Kupang
• Specialty aquaculture hatcheries and shrimp farms purchasing high-protein earthworm meal

Market Evidence & Context

Existing organic fertilizer in NTT consists of raw, uncomposted cow dung or basic traditional compost that has high weed seed contamination, active plant pathogens, and low nutrient availability. Farmers are hesitant to use uncertified manure. A mechanized vermicompost plant in KIB delivering lab-certified, weed-free, pathogen-free Kascing in professional branded packaging captures commercial agriculture contracts.

Raw livestock manure, corn harvest residues, and food processing wastes are sourced from cattle abattoirs, rural farming cooperatives, and KIB tenants.

Seasonality & Supply Continuity

Operating continuously year-round. Vermicompost demand peaks ahead of the rainy season planting window (November–January).

Collection & shipping

Raw manure is hauled via tipper trucks directly to KIB pre-composting pads. Finished bagged Kascing is dispatched via freight trucks across Timor and island regencies.

Procurement & handling costs

Raw manure and agricultural residues are acquired at nominal handling costs. Labor for bed harvesting and mechanical screening represent primary operating expenditures.

Investors can establish a large-scale covered vermiculture facility (5,000–10,000 m² footprint) utilizing automated windrow turning, continuous-flow worm beds, and rotary trommel screeners.

Business process

1. Raw manure receiving on concrete apron, mechanical blending with shredded corn cobs/sawdust to achieve C:N 30:1
2. Hot aerobic pre-composting (55°C–65°C for 14–21 days) to destroy weed seeds, pathogens, and parasitic nematodes
3. Cooling and feeding conditioned organic compost into elevated continuous-flow vermiculture worm beds (CFT beds)
4. Active earthworm digestion: earthworms consume organic matter, excreting humic-rich microbial castings over 30–45 days
5. Continuous bottom-cutting mechanical harvest of finished castings, followed by air drying to 25%–30% moisture
6. Rotary trommel fine screening (3 mm mesh) to cleanly separate pure vermicompost from cocoons and stray worms
7. Automated bagging into 25 kg / 50 kg branded moisture-barrier bags, palletizing, and warehouse staging

Primary operational risks include high ambient summer heat stressing earthworms, residual chemical de-wormers in manure poisoning colonies, and flooding.

Extreme summer temperatures (>36°C) causing worm mortality and bed abandonment

Construct high-roof shaded pavilions with automated evaporative micro-misting cooling and maintain thick bedding mulch layers.

Residual chemical veterinary antibiotics or anti-parasitic de-wormers in fresh manure killing earthworms
