Pure Organic
Oyster Shells Powder
Milled from naturally accumulated marine oyster shells in Ada-Kasseh, Ghana. Superior, bioavailable calcium carbonate for commercial poultry feed formulations, snail farming, and agricultural soil conditioning.
Two Purpose-Milled Granule Grades
Whether you produce commercial layer mash, blend mineral premixes, or condition acidic soils, we mill shells to exact particle size specifications.
Layer Hen & Snail Coarse Grit
Crushed shell particles calibrated to remain in the bird's gizzard overnight, providing continuous slow-release calcium during nocturnal eggshell calcification. Dramatically reduces cracked and soft-shelled eggs.
- Particle Size: 1.0 mm – 3.5 mm
- Primary Use: Commercial poultry layers & snail breeders
- Packaging: 50 kg heavy-duty woven sacks
Fine Milled Calcium Meal
Fine-pulverized natural mineral meal engineered for complete homogeneity in compound feed mixers, vitamin-mineral premixes, and as a natural pH-balancing liming agent for acidic farm soils.
- Particle Size: 100 mesh (< 150 µm / 0.15 mm)
- Primary Use: Feed premixes, cattle feeds, organic soil liming
- Packaging: 50 kg PP bags & 1-Tonne bulk sacks

Why Feed Formulators & Farmers Choose GPA
We handle the entire production chain in Ghana: from coastal collection to mechanical cleaning, sun drying, precision milling, and quality sacking.
Superior Bioavailability
Natural oyster shell calcium has a crystalline structure that birds and animals digest more efficiently than mined quarry limestone, containing natural trace marine minerals (magnesium, zinc, phosphorus).
Dependable Volume & Delivery
With reliable industrial milling operations at our Ada-Kasseh plant, commercial feed millers can rely on scheduled, uninterrupted deliveries throughout Greater Accra, Eastern, Central, and nationwide.
Circular Coastal Economy
Our operations directly support artisanal oyster-harvesting communities in Ada-Kasseh by clearing coastal shell mounds and converting biological byproduct into essential agricultural inputs.
Essential Calcium for Livestock & Agriculture
Calcium deficiency in commercial animal husbandry causes severe economic losses: cracked eggshells, slow snail growth, and poor crop yields from acidic soil. GPA provides the natural solution.
Commercial Poultry Nutrition
Coarse oyster shell particles stay in the gizzard, releasing calcium through the night to ensure thick, uniform eggshells and strong skeletal structure in laying flocks.
Snail Farming (Heliciculture)
African giant snails require rich organic calcium carbonate for strong shell growth and preventing cannibalism or brittle shells in high-density breeding pens.
Agricultural Soil Conditioning
Fine milled shell powder acts as a natural soil liming agent, neutralizing soil acidity (low pH) and releasing vital calcium without the shock of synthetic chemical lime.
