Island Spirit PEI has worked on research projects with |Bio|Food|Tech to develop Natural Health Products from oyster, including calcium from oyster shells.
Most of us are aware of the calcium content in oyster shells, as they are often recommended as a dietary supplement for animals and humans. However, the versatility and benefits of these shells go beyond their nutritional value. Oyster shell is composed of protein polysaccharides, minerals such as magnesium and phosphorus, and boasts a whopping 95% calcium carbonate content. Interestingly, calcium carbonate derived from oyster shells is not only biologically superior, but also has an edge in environmental sustainability when compared to open-pit mined limestone. In this blog post, we will delve deeper into the numerous applications of calcium carbonate from oyster shells and explore the eco-friendly benefits of this sustainable resource.
Highest Value Applications of Calcium Carbonate
Calcium carbonate is a versatile and essential compound used pharmaceuticals and environmental remediation.
+ Pharmaceuticals: Calcium carbonate is a staple ingredient in many over-the-counter antacid medications, helping to alleviate heartburn, indigestion, and acid reflux symptoms.
+ Environmental Remediation: Calcium carbonate can be employed to remediate contaminated groundwater by neutralizing harmful acids.
Sustainability Benefits of Oyster Shells
One major advantage of utilizing oyster shells as a source of calcium carbonate is their sustainable harvesting methods. Unlike open-pit mining, which entails large-scale destruction of ecosystems and landscapes, oyster shells are a natural byproduct of aquaculture and seafood consumption. By repurposing these shells, we can lighten the environmental impact of industrial processes and reduce reliance on ecologically harmful mining practices.
Furthermore, calcium carbonate from oyster shells demonstrates better bioavailability (absorption) than that sourced from inorganic limestone. This increased absorption rate renders it more effective for certain applications, allowing for a smaller quantity to be used while still delivering the same benefits.
Oyster shells are an impressive and eco-friendly source of calcium carbonate, offering a viable and sustainable alternative to traditional limestone-derived calcium carbonate. With versatile applications across various industries, as well as proven better bioavailability and environmentally-friendly harvesting methods, oyster shells hold the potential to serve as a key ingredient in future endeavours that aim to achieve an eco-conscious and efficient world. By embracing sustainable resources, we can work towards building a greener and healthier future for all.
