Organic waste is not a disposal problem; it is an unbalanced raw material. Fresh manure and food waste carry the nitrogen, phosphorus, potassium and organic matter that soil needs, but in a form that is too wet, too salty, too unstable and too smelly to sell. Composting fixes the instability, granulation fixes the handling, and drying fixes the storage. What is left is a uniform, bagged organic fertilizer that farmers buy season after season.
The economics work because the raw material is free or even paid for. A 5 t/h organic fertilizer line producing a 40 kg bag every few seconds converts a waste-handling cost into a product with a wholesale price. The variables that decide payback are the moisture of the incoming waste, the fermentation method, the fertilizer form (powder or granule) and the level of automation.

A lower-investment route: dewater, ferment, crush, screen and pack compost as powder fertilizer without granulation.

Nutrient-dense but wet and odorous; sấy khô, fermentation and deodorising precede powder or pellet production.

Disc granulation and rotary drying turn fermented poultry manure into 3–5 mm organic pellets.

Bulky manure mixed with bedding; groove-type turners and in-vessel systems handle the volume.

High-moisture organic waste needs in-vessel fermentation and secondary composting to become clean compost.

Rơm, thân cây, crop residue and manure are blended to the right C/N ratio, then composted and granulated.

Solid liquid separation removes water first so the solids can be composted and the liquid reused.
Xem chi tiết →A solid liquid separator lowers moisture from 80–90% to about 60–65%, cutting the volume that has to be turned, dried and shipped.
Windrow turning or in-vessel aerobic fermentation raises the temperature above 55 °C for several consecutive days, killing pathogens and weed seeds and stabilising the organic matter.
Cage mill or chain crushers reduce the compost below 3 mm; mixers blend in binders, axit humic, trace elements or chemical nutrients.
Đĩa, trống quay, wet or double roller granulators form the powder into 2–5 mm pellets with a granulation rate up to 93%.
A rotary dryer brings moisture down to 12–14%, the cooler stabilises the pellet, the screener recycles fines and the coater prevents caking.
Automatic weighing and bagging into 25/40/50 kg bags or jumbo bags, ready for retail or bulk delivery.
| Waste stream | Moisture | Key first step | Typical fertilizer output | Recommended line |
|---|---|---|---|---|

Livestock manure, especially cow dung and chicken manure, is the easiest because it already has a balanced nutrient profile and a workable carbon/nitrogen ratio. Food waste and sludge are richer in moisture and need in-vessel fermentation plus a bulking agent before they behave like compost.
Đúng, and many customers do. The composting, nghiền nát, mixing and packing equipment is shared. When the market asks for pellets you add the granulator, dryer, mát hơn, screener and coater, keeping existing machines in the same layout.
A 1–2 t/h line including windrow fermentation typically needs 800–1,500 m². A 5–10 t/h granule line needs 2,000–5,000 m², Và 20 t/h and above with in-vessel fermentation usually requires 8,000 m² or more. We supply a layout drawing so you can confirm the land before ordering.
Calculate the daily waste available from your farm, feedlot or municipality first, then convert to hourly output assuming 8–10 working hours per day. Composting and fertilizer lines are usually sized slightly above that figure so seasonal peaks do not become a bottleneck.
