This study aimed to optimize and validate an analytical methodology for determination of 1hydroxypyrene in urine of workers involved in harvesting sugar cane. The method used for determining 1hydroxypyrene in human urine is the enzymatic hydrolysis, extraction and clean-up by solid phase extraction (SPE) and quantified by high performance liquid chromatography with fluorescence detection (HPLC ...

The sugar cane industry produces significant amounts of cane trash and bagasse. Inappropriate disposal of agro-wastes can lead to environmental problems. Converting wastes such as cane trash and bagasse (Bg) to a fertilizer and conditioner is the aim of sustainable waste management in sugar cane industry. Cow dung (CD), kitchen waste (KW), and sewage sludge (SS) were mixed with bagasse as amend...

In South Africa (SA), individual consignments of shredded cane are analysed by the direct analysis of cane method (DAC). Although this procedure is capable of producing excellent sampling and accurate analysis of consignments, it is labour intensive. NIR has been used by several sugar industries for determining cane quality for cane payment purposes. Earlier work in SA indicated that At-line NI...

Rapadura is the commercial name for unrefined dehydrated sugarcane juice. Rapadura is produced in 25 countries, for an estimated total of 13 million tons per year. It is considered a basic food for the School Meals Program (PNAE) in Brazil, which serves 37 million meals to schoolchildren each day. During the production of rapadura, carcinogenic compounds including polycyclic aromatic hydrocarbo...

The objective of this research is to design an approach for selecting appropriate raw materials for facial tissues in Iran. There are three possibilities to maintain raw materials: (1) imported virgin pulp; (2) bagasse (sugar cane residue) plus some imported raw materials; and (3) recycled paper plus some imported raw materials. Owing to the shortage of raw materials as well as the high rate of...
