Possibly similar uses to other species in this genus which include: agroforestry Uses: The decomposed husk is commonly used in potting soil. Other Uses: Macadamia shells may be used as fuel, generating sufficient energy to dry wet, in-shell nuts. The oil from the seed is used in cosmetics. The green seed hulls contain approximately 14% of tannins.

Cosmetic: Used to improve the physical appearence of a person.

Fuel: Usually wood, plant materials that have been mentioned as being a good fuel.

Oil: Vegetable oils have many uses, as lubricants, lighting, soap and paint making, waterproofing etc. This does not include the edible oils unless they are also mentioned as having other uses.

Plant breeding: Used in producing new species of plants or improved varieties.

Tannin: An astringent substance obtaied from plants, it is used medicinally, as a dye and mordant, stabilizer in pesticide etc.

Management: Standard: Plants grow to their standard height. Harvest fruit, seeds, or other products. Non-Destructive management systems.

New Perennial Crop: Most new crops were important wild plants until recently, although some are the result of hybridization. They have been developed in the last few, decades. What they have in common is that they are currently cultivated by farmers.

Staple Crop: Oil: (0-15 percent protein, 16+ percent oil). Some of these are consumed whole while others are exclusively pressed for oil. Annuals include canola, poppyseed, maize, cottonseed, sunflower, peanut. Perennials include high-oil fruits, seeds, and nuts, such as olive, coconut, avocado, oil palm, shea, pecan, and macadamia. Some perennial oil crops are consumed whole as fruits and nuts, while others are exclusively pressed for oil (and some are used fresh and for oil).
