Pelletizing Technology for Fertilizer & Soil Amendment Products
Since 1972, Mars Mineral has provided agglomeration and pelletizing solutions that help manufacturers convert difficult feedstocks into durable, marketable granular products for fertilizer, soil amendment, biochar, biomass residue, biosolids, and nutrient recovery applications.
GRANULAR PRODUCT APPLICATIONS & FEEDSTOCKS
Whether you are scaling a proprietary organic soil-amendment blend or optimizing a high-throughput commercial fertilizer line, process consistency is everything. Unpredictable material behavior leads to high attrition, wasted product, and costly equipment downtime.
GRANULAR NUTRIENTS
Soil Amendment
Biochar
Biosolids
Animal Waste
Lime & Gypsum
NUTRIENT MINERALS
Recycled Byproducts
Built for Reliablity
PROVEN PELLETIZERS. CONSISTENT PERFORMANCE.
Our pelletizing equipment supports the circular economy by transforming byproducts into marketable materials that can be reintroduced into the supply chain rather than the waste stream.
Engineered for Results
Why producers from agile innovators to global enterprises partner with us.
Proven Versatility
Handle everything from difficult organic powders to heavy minerals and chemicals
