The aquaculture industry in Singapore, while trying to meet the demand to produce safe and quality seafood, enables an annual consumption of 100 million kilograms of frog flesh and fish. More than 20 million tonnes of frog skins and fish scales are discarded every year.
Technology solution: A biomaterial made from discarded bullfrog skin and fish scales
Scientists and researchers at Singapore’s Nanyang Technological University (NTU) have developed a new biomaterial with discarded fishery by-products that could help in bone repair
The material contains the same compounds that are in bones and helps bone-forming cells to multiply – creating new bone cells. This material acts as a scaffold and has many beneficial uses regarding bone tissue regeneration.
Using aquaculture waste and turning it into a valuable resource can help close the waste loop in the future.

Nitrogen runoff from agricultural use, as well as other pollutants, is flooding major rivers and large bodies of water.
Pollution creates hypoxic conditions, which fosters algae blooms and further destroys the aquaculture.
This deadly combination impacts drinking water, recreational use of the shoreline, kills marine life and creates human health hazards.
South Florida has been in the news for toxic algae blooms that are causing health and environmental damage to coastal areas.
FAQs on Manmade Floating Islands:
Manmade floating islands are built using a recycled polymer mesh to support aquatic-friendly plant life. The roots are submerged in water to help filter pollution, cleanse toxins, and absorb the excess nitrogen before it can create algae blooms.
Local plants are selected to ensure viability and self-sustenance.
Floating islands are anchored in bodies of water, large rivers, and offshore to clean waterways and recreate wetland areas.
Mimicking mangrove forests, which are quickly disappearing due to habitat loss, rising water, and warming oceans, the islands create several solutions:
Micro-environments that support plant life used to clean the air and water through natural processes;
Above the waterline: a habitat for migrating birds, turtles, reptiles, and other species;
Below the waterline: a marine habitat supporting fish and related marine species.

The implementation of manmade floating islands is a global multi-million dollar industry. However, wider-scale use is required to have a more pronounced effect.
Cost and custom-build time are determined by size and complexity.
Islands can take only a few weeks to months to mature, and are self-sustaining.
Continued adoption of manmade islands to reduce water pollution, improve air quality, and create new habitats for birds and marine life.
