Fertilizers and Manures
Overview
Pelleted organic fertilizers are produced from agricultural and biological materials of livestock, livestock, and plant origin that have a high content of organic matter and essential plant nutrients. These materials, in their natural state, generally have low density, irregular particle size, variable moisture content, and are difficult to handle, which limits their storage, transport, and field application.
Pelletizing makes these inputs more uniform, stable, and standardized, allowing for their efficient use as slow-release solid fertilizers.
The process is particularly suitable for fibrous, pasty, or particulate materials, provided they undergo appropriate pre-treatments such as drying, homogenization, or mixing.

Agricultural Applications
Soil conditioning and restoration
Fruits and vegetables, grains, pastures and reforestation. Organic and regenerative agriculture.
Fertilization of annual and perennial crops
Commercial Applications
Marketing in small, medium or large packages
Supply for agricultural cooperatives and resellers.
Use in proprietary formulations or customized fertilizer lines.
Final result of the pellet
Solid, stable and uniform pellet
Easy to store, transport and apply.
Higher added value compared to the raw material.
Technical observations
For use in animal feed, compliance with current legislation is required (MAPA, ANVISA and good sanitary practices).
For energy use, the compatibility of the pellet with the thermal equipment must be validated (ash, emissions and calorific value). Ideal process moisture is generally between 10% and 15%.
Pre-grinding recommended below 6 mm. Typical compaction temperature between 80 and 100 °C, depending on the material.
Benefits of pelleting for food waste
Technical and functional benefits
Gradual release of nutrients, reducing losses and increasing efficiency.
Slow and continuous release of nutrients
Nutritional homogeneity in each pellet.
Greater efficiency in absorption by plants.
Benefits
Logistics
Average volume reduction of up to 4:1
Storage and transport optimization
More efficient and economical transportation
Economic and environmental benefits
Viable production even on a small scale.
Full utilization of waste
Reducing emissions associated with disposal and transportation.
Promoting a circular economy in rural areas.
