Lifecycle Inventory Analysis on Material Recycling System of Disposable Diapers

Toxic Emissions from British and American Brands of Disposable Diapers

Mice were exposed to the volatile emissions of 4 samples of disposable diapers. Two samples (X-Brit and Y-Brit) were manufactured in Britain, the other two (X-Amer and Y-Amer) were of the same brands but manufactured in America. A modification of ASTM-E 981 was used to measure Sensory Irritation (SI), Pulmonary Irritation (PI), and Airflow Limitation (AFL). A Functional Observational Battery wa...

Life Cycle Inventory Analysis of Recycling: Mathematical and Graphical Frameworks

A mathematical framework of the life cycle inventory (LCI) analysis in life cycle assessment (LCA) of recycling is systematically reviewed with the aid of graphical interpretation. First, the zero burden approach, which has been applied to LCI analyses of waste management systems, is theoretically justified in terms of relative comparison of waste management options. As recycling is a multi-fun...

A production–recycling–inventory system with imprecise holding costs

This paper presents an optimal control recycling production inventory system in fuzzy environment. The used items are bought back and then either put on recycling or disposal. Recycled products can be used for the new products which are sold again. Here, the rate of production, recycling and disposal are assumed to be function of time and considered as control variables. The demand inversely de...
