Macadamia Uses
Water Purification
Macadamia nuts, specifically the shells, can be repurposed for water purification due to their porous nature and potential for adsorption.
The high porosity of the shells allows them to trap impurities, making them useful for filtering water. Here's how you can use macadamia nuts for water purification:
Activation Process
Macadamia nutshells can be converted into activated carbon by heating them at high temperatures in the absence of oxygen. This process creates a permeable structure that increases their adsorption capabilities.
DIY Water Filter
Ground or crushed macadamia nutshells, when used in a filtration system, can effectively remove certain impurities and contaminants from water. Consider constructing a simple filtration system using a container filled with layers of nutshells. As water passes through, the porous shells can help trap particulates and certain pollutants.
Absorption of Contaminants
Chemical Adsorption: Due to their porous structure, activated carbon, derived from macadamia nutshells, can attract and retain various organic compounds, some heavy metals, and potentially certain chemicals present in water, aiding in purification.
Pilot Studies
While macadamia nutshells have shown promise as a potential water treatment medium, it’s crucial to note that their effectiveness may vary based on the type and concentration of contaminants present in the water. Pilot studies and tests should be conducted to evaluate their specific adsorption capabilities for the targeted contaminants.

Macadamia Uses
Sandblasting
Macadamia nut shells can be used as an alternative blasting material in a process known as "nutshell blasting."
This technique involves using crushed or ground macadamia nut shells as an abrasive material to clean, strip, or prepare surfaces.
The hard and durable nature of macadamia nutshells makes them an effective means of removing paint, corrosion, or other surface contaminants without harming the underlying material.
Nutshell blasting is considered environmentally friendly and is often used in areas where traditional sandblasting might be too harsh or generate environmental concerns, especially when dealing with surfaces that require gentler treatment.
The shells are crushed into fine particles and propelled at high pressure using specialised equipment, such as traditional sandblasting machines.
Nutshell blasting is typically less abrasive and inflicts less damage to the substrate while still efficiently removing coatings or contaminants. It’s commonly used in industries such as automotive, aerospace, and restoration for delicate or sensitive surfaces.
Blasting Benefits:
- Eliminates rust, mould, and paint.
- Provides a smooth finish, ensuring better adhesion and longer-lasting paint.
- Various materials can be used to achieve different effects.
- Environmentally friendly as no stripping chemicals are required.
