The five systems of an organic fertilizer plant
The mistake that damages most projects is buying a processing line before the fermentation system is settled. Fermentation decides how much material is in the plant at any moment, how much labour it needs, how much odour it generates and how stable the material is when it reaches the granulator. Everything downstream inherits those decisions.
- Feedstock intake — reception bay, weighing, separation of plastic and stone, dewatering or liquid addition, mixing of amendments, buffer storage sized for the delivery pattern.
- Fermentation — windrow, groove, aerated static pile or in-vessel, with the turning or aeration regime, leachate collection and odour management that the site allows.
- Processing — grinding, screening, granulation, drying, cooling and coating, sized on cured material and matched step by step so no machine is a bottleneck.
- Product finishing — precision blending if you sell formulations, bagging at 5–50 kg or 500–1,000 kg, palletising, wrapping and covered storage.
- Utilities and interfaces — power distribution, water, steam or hot air, compressed air, dust and odour extraction, drainage, hardstanding, access roads and the control philosophy that links them.

Match the plant to the scale you can actually feed
| Plant scale | Finished output | Fresh feedstock | Typical configuration |
|---|---|---|---|
| Small / farm cooperative | up to 3 t/h | 15–40 t/day | Groove or covered windrow fermentation, powder line, 1–2 bagging scales |
| Medium / commercial | 4–10 t/h | 60–250 t/day | Groove or aerated pile fermentation, granular line with dryer, automatic bagging |
| Large / industrial | 15–50 t/h | 400–1,500 t/day | Bays or in-vessel fermentation, parallel processing lines, automatic bagging and palletising |
| Urban / odour-sensitive | 1–8 t/h | 20–200 t/day | In-vessel fermentation, enclosed processing, extraction and biofilter, high automation |
Fresh feedstock figures assume a well-managed process with roughly 30–45% of fresh mass reporting to finished powder or granules; the exact ratio is calculated in the mass balance for each project.

How the scope is normally split
Local contractor
Excavation, foundations and floor slabs, bay walls, building envelope, insulation, cladding, roof structure, utilities to the battery limit, roads and fencing.
Customer team
Permits and registration, feedstock contracts, labour, working capital, product marketing and the decision on the automation level the plant can maintain.
Joint scope
Layout freeze, foundation verification, power connection to the panel, water supply, commissioning support and the trial production batches.
04
The configuration decisions that matter most
- Fermentation residence time — deciding between 10 and 30 days changes the bay footprint, the material inventory and the labour more than any equipment choice.
- Water balance — whether the plant removes water by mechanical dewatering before fermentation, by evaporation in drying, or by both, decides the utility load and the odour profile.
- Dryer or no dryer — powder lines normally need none; granular lines almost always do, and the dryer is the largest single thermal and electrical load in the plant.
- Automation level — an automatic bagging and palletising line only pays back if it is maintained; many plants are better served by semi-automatic bagging and more attention to fermentation control.
- Layout for expansion — reserving the drying and granulation building footprint in phase one is nearly free; inserting it later into a cramped site is not.

FAQ
Plant engineering questions
Do you supply the whole plant or only the machines?
Both models exist. Most customers take process design plus equipment, control and commissioning from us, and civil works from a local contractor. On smaller plants we also quote complete supply with erection supervision on site.
Can one line produce both powder and granules?
Yes, and it is a common request. The shared section is intake, fermentation, grinding and screening; the granular route adds granulation, drying, cooling, a second screening and coating. A dual-purpose plant usually shares the grinding and bagging sections and switches the middle of the line.
What information do you need to quote a plant?
Feedstock type and tonnes per day with seasonal peaks, moisture and contamination, target product and bag size, available site area and shape, power supply, water source, climate and the labour you expect to employ.
How is the plant capacity expressed?
In tonnes per hour of finished product at the bagging end, and in tonnes per day of fresh feedstock at the receiving end. Both numbers appear in the design basis, because a plant is only consistent when intake and output match through the mass balance.
Send us your design basis
Tell us the feedstock, the daily tonnage and the product you want to sell. The engineering team replies with the plant configuration, the equipment scope and the information we still need before layout drawings start.
- Feedstock profile — type, moisture, contamination, seasonal peaks
- Capacity — t/day fresh material or t/h finished fertilizer
- Product — powder, granules, bagged retail, bulk compost
- Site — available area, power supply, water, access road
