Alumina Ceramic Injection Molding Process Helps Regenerate Great Barrier Reef

The glory days of Australia's Great Barrier Reef are no secret. It's repeatedly faded by warming waters, battered by storms, contaminated by agricultural runoff and threatened by disease.

To help some of the three most miserable areas, scientists packed 10,000 alumina ceramic devices with young coral and sunk them to the seafloor. They are manufactured through the ceramic injection molding process. They have good mechanical properties, wear resistance, corrosion resistance, etc., and can achieve automated production and mass production, so production costs can be reduced during mass production.

Ceramic powder metallurgy process is energy-saving and environmentally friendly. The injection process does not require a large amount of energy to melt the metal. Compared with traditional metallurgical methods, it consumes less energy, does not produce a large amount of waste gas and waste water, and is more environmentally friendly.

Coral propagation experts explain that the 15cm wide ceramic seeding devices are designed to be fixed to the reef. In a little over a year, the babies will grow from the gaps into recognizable coral.

A team of coral propagation experts is conducting the largest ever coral restoration research trial in the world. While they're starting relatively small, they hope to ship 2 to 3 million devices over the next five years.

As climate change continues to damage coral reefs around the world, the institute is developing a suite of technologies, including selective breeding of warming-resistant corals, and aquaculture facilities that can cost-effectively raise corals.
Although much of the work is still in the research and development stage, they are confident of success. For example, the coral larvae they raise have a survival rate of 50 to 70 percent, whereas in the wild, only one in a million larvae will grow into adults.

Are there risks in disturbing natural coral?
While the project brings hope to the world's coral reefs, interference with nature also poses risks to the natural environment.

Scientists are trying to understand what impact this might have on natural populations. For example, genetic bottlenecks are currently being studied.

To prevent their project from altering the reef's appearance, the researchers also selected species based on functional diversity.

"Yes, coral reefs of the future may look different than they do today, even in a physical sense," the scientists said. "Reefs affected by severe bleaching may recover and represent healthy reefs, but it looks likely It’s not like it used to be.”

The project may help improve coral reef survival, but it's not enough. If the world does not drastically reduce carbon emissions, the world's coral reefs will almost completely disappear.

Our ceramic metallurgical process can produce environmentally friendly, corrosion-resistant, low-cost devices to help environmentally friendly recycling projects.
