Shell Waste Management and Utilization: Mitigating Organic Pollution and Enhancing Sustainability

Abstract: Every year, close to 8 million tons of waste crab, shrimp and lobster shells are produced globally, as well as 10 million tons of waste oyster, clam, scallop and mussel shells. The disposed shells are frequently dumped at sea or sent to landfill, where they modify soils, waters and marine ecosystems. Waste shells are a major by-product, which should become a new raw material to be used to the best of their potential. There are a number of applications for waste shells in many fields, such as agriculture, medic… Show more

“…In the current study, the seashell biocomposite was developed from recycled food waste. Since seashell waste are produced annually with large amounts internationally, for example China produces about 10 million tons of waste seashells annually, and The European Union produces 600,000 tons of seashell waste that are dumped in landfills resulting in visual pollution, unpleasant smell, and microbial contamination due to microbial decomposition of salts into undesired gases [73][74][75][76]. Therefore, numerous studies have proposed recycling seashells and integrating them as fillers and aggregates in building materials such as mortar, cement, and concrete [77,78].…”

“…Therefore, relevant classification and composition screenings of the collected waste are done in this paper and show that bio-shells, one of the kitchen waste, can be good choices for replacing traditional concrete aggregates. As reported by previous researchers, nearly 10 million metric tons of shells of oysters, clams, scallops, and mussels are discarded globally every year 2 . Furthermore, a comprehensive survey was carried out to assess the situation of restaurants in selected provinces of China and the Republic of Belarus, the collected data revealed that the Belarusian restaurant chain brand “Sea Food” alone generates amounting to over 100 catties of discarded seashells per day.…”

“…An important source of bCC is mollusc shells from aquaculture. , This is a farming sector of growing economic relevance and nowadays the production of mollusc shells by aquaculture is about 15 Mton per year . The majority of these shells are not collected and become waste which represents a major economic and environmental issue. Their valorization by sustainable and green processes is desirable and can be a good example of circular economy …”
