Cracking a hard nut problem

IT'S been a hard nut to crack but Marc Harrison has found a solution.

The artist, and Husque owner, has been working with macadamia nuts for more than 15 years, and has now created the world's first wooden macadamia nut cracker.

"We have a customer who took out 10,000 macadamia trees, so I did some research. Timber from macadamia trees is a hard wood, so I thought let's make a macadamia nut cracker,” he said.

Marc was among the exhibitors at the AgFutures Conference, demonstrating his innovation using an agricultural product.

He has become somewhat of an expert in macadamia nut ingenuity.

In 2000, he came up with the idea of using macadamia nut shells to build bowls.

He now sells a gorgeous array of quirky dishes and containers using the solid material.

The Queen of daytime TV, Oprah, is even the proud owner to one of his creations.

After the kernels are removed, the shells can be milled into fine particles, melded with a polymer, then placed into a mould.

"Macadamia shells are a valuable by-product, they can be used as a biofuel or as a mulch,” he said.

"As a biofuel it's just being used to burn because it yields a higher energy per kilo than coal dust.

"So it's a very efficient biofuel.”

At the moment Marc gets his shells from processors in southern Queensland and northern New South Wales.
