Located in Alkmaar, Mpumalanga, the Golden Macadamias Processing Facility is one of the world’s largest and most advanced. Handling up to 30,000 tons annually, it combines automation, climate-controlled storage, and predictive sorting to ensure quality, safety, and traceability ,delivering world-class, grower-owned macadamias to customers worldwide.
Innovation & precision drives everything
Smart Curing Automation
Advanced systems monitor and manage curing, the critical first step in macadamia processing.
Climate-Controlled Cool Store
Our temperature- and humidity-regulated storage maintains nut quality for 8-12 weeks, allowing us to sort based on predictive lab data rather than relying solely on raw output.
Rapid Farm Intake
We move crop off the farm quickly to preserve shelf life and take full control of product quality from the start.
Ready-to-Eat Capability
Our dedicated RTE zone includes validated pasteurisation (5-log Salmonella reduction), giving us the flexibility to pack both bulk and ready-to-eat formats.
Cold Storage & Export Efficiency
NDX partners with BRC-approved cold storage near key ports, ensuring compliance, premium conditions, and streamlined logistics for faster, reliable delivery worldwide.

Customer labels printed directly at the warehouse
It starts here
-
Between February and July, ripe macadamias naturally fall to the orchard floor when ready. Farmers collect these fallen nuts daily or multiple times per week using manual or mechanical methods. This prompt collection is crucial, any delay exposes nuts to moisture, pests, and fungal growth that can compromise quality and reduce their commercial value.

-
De-husked nuts undergo initial air or bin-drying to reduce moisture content to 10-12%. This on-farm drying in ventilated bins or racks prevents mold growth, improves shelf life, and prepares the product for more controlled drying processes at the processing facility.
-
Growers transport their NIS to Golden Macadamias' processing facility in Alkmaar. Upon arrival, deliveries are registered and a representative sample is drawn for quality grading and payment assessment. This sampling process determines the financial return to the grower based on quality metrics.
Golden Macadamia Facility
-
A comprehensive 20kg sample is extracted from each delivery, representing the entire truckload. This sample undergoes testing for size distribution, kernel recovery rates, and defect levels. The transparent assessment ensures fair payment, and growers must approve the results before their nuts proceed to processing.
-
NIS enters temperature and humidity-controlled drying bins where moisture content is carefully reduced to below 1.5%. This precision drying process takes 14-21 days and is essential for achieving crisp, high-quality kernels while preventing spoilage and ensuring long-term storage stability.
Processing Paths
Depending on the product type, nuts follow one of three specialised lines:
