To evaluate the impact of hazardous chemicals in solid wastes on man and other organisms, it is necessary to have information about amounts of chemical present, extent of exposure, and chemical toxicity. This paper addresses the question of organism exposure by considering the major physical and biological transport pathways and the physicochemical and biochemical transformations that may occur...

Food processing produces large quantities of by-products. Disposal of waste can lead to environmental and human health problems, yet often they can be turned into high value, useful products. Crustacean shell wastes from shrimp, crab, lobster, and krill contain large amounts of chitin, a polysaccharide that may be extracted after deproteinisation and demineralization of the exoskeletons .crusta...

Food processing is a major industry that is rapidly growing because of a demand for packaged foods in urban areas. In Atlanta, Georgia, several food processors are in the business of packaging fresh salads for grocery stores. These companies have large processing facilities where vegetables, such as lettuce, cabbage, carrots, onions etc. are cleaned, chopped, mixed and packaged. In a typical op...

Animals are primarily limited by their capacity to acquire food, yet digestive performance also conditions energy acquisition, and ultimately fitness. Optimal foraging theory predicts that organisms feeding on patchy resources should maximize their food loads within each patch, and should digest these loads quickly to minimize travelling costs between food patches. We tested the prediction of h...

food security in iran has closely relation with wheat and flour and its waste. the study of food pattern in the iran provinces shows that bread is the major source of calorie and protein in the country daily diet. the main purpose of this study was to analyze factors, affecting bread wastes in the bahar county in the hamedan province. the research was conducted based on the applied-descriptive....

An interface to ADM1 was developed to estimate the solid waste composition from its practical characteristics. The interface was based on COD, elemental, charge and covalent bond balances to conceal any error in collected characteristics from different sources. The interface was validated by reported characteristics of manure and food wastes and determined with relevant accuracy the wastes’ com...

Problem statement: An Anaerobic Digestion (AD) process, traditionally applied to wastewater and sewage sludge treatment, has a great potential in the valorization of foodprocessing industry wastes. Approach: This study is focused on the evaluation of the theoretical biogas and methane production of some food wastes, coming out from rice, hazelnut and wine processing, on the grounds of their phy...

Fruit wastes are one of the main sources of municipal waste. In order to explore the potential of fruit wastes as natural resources of bioactive compounds, the antioxidant potency and total phenolic contents (TPC) of lipophilic and hydrophilic components in wastes (peel and seed) of 50 fruits were systematically evaluated. The results showed that different fruit residues had diverse antioxidant...

Composting of food processing waste was analyzed as a biological process and an engineered system. The goal is to establish fundamental principles design criteria that would aid its adoption management practice. Characteristics the inflow, reactor, outflow were evaluated. Success bioreactor found be largely dependent on microbial community structure, physical properties biodegradable (BW), aera...

A kinetic model was developed for the prediction of HTL product yields based on a chemical mechanism. The after experimental studies food wastes and processing wastes. parameters were determined by training data Two other models from literature also tested. calculated compared with large range literature. Yields bio-oil char can be predicted process conditions, temperature, holding time, dry ma...
