Mô hình hóa các tác động tiềm ẩn đến môi trường của quá trình tổng hợp các-bon chấm lượng tử từ chitosan

Abstract

The shrimp farming industry not only brings significant economic value but also plays an important role in the region’s sustainable development strategy. However, this industry also faces many challenges, such as environmental pollution from wastewater and sludge, shrimp diseases, and the impacts of climate change. Therefore, utilizing by-products such as shrimp heads and shells from the shrimp processing process to extract chitosan helps reduce the environmental burden caused by the disposal of these waste materials. In this study, the potential environmental impacts of the synthesis of chitosan-based carbon quantum dots were calculated using a mass flow analysis with the aid of a calculation tool over four studied scenarios and three different supplied energy sources. The results indicated that using chitosan as a raw material and transitioning from coal to petroleum, natural gas help to mitigate the environmental impacts of the synthesis.
