An Overview of the Applications of Periwinkle (Tympanotonus fuscatus) Shells
Current Journal of Applied Science and Technology, 2021 The waste generated by the periwinkle (Tympanotonus fuscatus) shell cannot be undermined. In coastal communities worldwide, periwinkle is a major source of proteins and other vital minerals in most delicacies. The shells of these aquatic species, notable for their nutrient provision, contribute to environmental degradation because of the indiscriminate

Comparative study of electrical resistance of disc-shaped compacts fabricated using calcined clams shell, Periwinkle shell and Oyster shell nanopowder [PDF]
Kragujevac Journal of Science, 2022 In this investigation, Clam, Periwinkle and Oyster shells were separately treated, calcined and ball-milled into nano powder. Each nano powder material was fabricated into disc of various lengths in three replicates.

Periwinkle Shell as Mixing Ingredient in Concrete: A Review
CONSTRUCTION, 2021 Growing population which also pushes for rising demand for seafood results in a generation of seashells which are thrown as environmental pollution waste after the edible meat is consumed. Meanwhile, the utilisation of natural resources as mixing ingredients for the production of concrete materials continues to increase over the year.

Shoreline oiling effects and recovery of salt marsh macroinvertebrates from the Deepwater Horizon Oil Spill [PDF]
PeerJ, 2017 Salt marshes in northern Barataria Bay, Louisiana, USA were oiled, sometimes heavily, in the aftermath of the Deepwater Horizon oil spill. Previous studies indicate that fiddler crabs (in the genus Uca) and the salt marsh periwinkle (Littoraria irrorata)

Investigating the Performance of Palm Kernel Shells and Periwinkle Shells as Coarse Aggregates in Concrete [PDF]
LAUTECH Journal of Civil and Environmental Studies, 2020 Excessive usage of materials is causing fast depletion of natural stone deposit. This study therefore investigates the performance of palm kernel shells (PKS) and periwinkle shells (PS) as alternatives coarse aggregates in concrete. Forty cubes and 40 cylinders each were produced with PKS and PS as replacement materials for granite.

Thermal, structural and acetylation behavior of snail and periwinkle shells chitin [PDF]
Progress in Biomaterials, 2017 This article reports a successful removal of CaCO3 from snail and periwinkle shells for the purpose of producing high quality chitin for possible application as bio-fillers in bone fixation materials. Experiment was designed with varying concentrations of acid and alkali for demineralization, deproteinization and deacetylation of the samples.
