“…The mixtures present better mechanical properties and fire-retardant behavior compared with neat recycled PE. Funabashi et al 15 evaluated method of biomass carbon ration of polymer filled with calcium carbonate using poly(butylene succinate) (PBS) with oyster shell powder and poly (lactic acid) (PLA) with nobiobased inorganic calcium carbonate. They observed that the estimation method is effective for polymer composites with CaCO 3 .…”

There is a high content of calcium carbonate in mussel and oyster shells, which can be used in the formulation of medicine, in construction or as filler in polymer materials. This work has as its main objective to obtain calcium carbonate from mussel and oyster shells and used as filler in polypropylene compared their properties with polypropylene and commercial calcium carbonate composites. The shellfish was milling and heated at 500 °C for 2 hours. The powder obtained from shellfish were characterized by scanning electron microscopy (SEM), X-ray fluorescence, particle size distribution and abrasiveness and compared with commercial CaCO 3 and mixed with polypropylene. The thermal and mechanical properties of polypropylene with CaCO 3 obtained from oyster and mussel shells and with commercial CaCO 3 were analysed. The results showed that CaCO 3 can be obtained from oyster and mussel shell and is technically possible to replace the commercial CaCO 3 for that obtained from the shells of shellfish in polypropylene composites.

“…11 The biomass carbon ratios of polymer composites filled with inorganic fillers such as carbonates were investigated. 21 In ASTM D 6866, the carbon from carbonate is regulated and omitted in order to reduce errors. However, in order to confirm the applicability of our method to carbonate and composites including carbonate, the pretreatments and biomass carbon ratios were studied.…”

The biomass carbon ratios of various chemical products were studied. The biomass carbon ratios of chemicals such as polymers, their monomers, starches, cellulose, calcium carbonate, charcoal, ethanol, and polymer blends were estimated by the ratios of 14 C to 12 C measured by accelerator mass spectrometry (AMS) based on ASTM D 6866. Preparations of the gaseous and liquid samples for the AMS measurements are described, and the pretreatment for carbonate is also explained. Repeatability and accuracy of the biomass carbon ratio evaluation by AMS are discussed. It was found that a new correction factor is necessary for cellulose other than 0.93, which is regulated as the correction factor for present modern carbon newer than 1950 in ASTM D 6866. The developed sample preparations of gaseous materials and carbonate were confirmed to be applicable for the AMS measurement of the biomass carbon ratio. The repeatability and accuracy of the biomass carbon ratio evaluation by AMS were confirmed for ethanol derived from biomass (bioethanol), a polymer blend of biomass-based poly(lactic acid) (PLA), and petroleum-based poly(butylene succinate) (PBS). Standard deviations of the bioethanol and the blend of PLA and PBS are 0.36 and 0.84%, respectively. The biomass carbon ratio evaluation by AMS has been proposed for the International Standard (ISO).

Running title: Bivalve shell-a functional and versatile biomaterialBivalve shells, available in abundance, have no eminent use and are commonly regarded as waste.Their improper disposal causes a significant level of environmental concern and also results in a waste of natural resources. Bivalve shell is formed by biomineralization and consists mainly of CaCO 3 with a small amount of organic matrix, giving it a potential for use as raw material.Recycling shell waste could potentially eliminate the disposal problem, and also turn an otherwise useless waste into high value-added products. The present review first describes the microstructure and physicochemical properties of bivalve shell, then focuses on its current Downloaded by [Florida International University] at 15:37 30 August 2014 ACCEPTED MANUSCRIPT ACCEPTED MANUSCRIPT 2 applications. Finally, the current status of bivalve shell studies and directions for future research are considered.
