A growing demand – above all in industrialised countries – for safer foods and cleaner production processes has been observed in recent times. This has led to a drive, by the agro-alimentary industries, for waste reduction and upgrading as a strategy to reduce costs and achieve new sources of income. In fact, waste may be a source of high-added value products potentially useful as beneficial fo...

Mispah form (FAO: Lithosol) soil contaminated with >380 000 mg kg−1 creosote was co-composted with cattle manure and mixed vegetable waste for 19 months. The soil was mixed with wood chips to improve aeration and then mixed with cattle manure or mixed vegetable waste in a ratio of 4:1. Moisture, temperature, pH, ash content, C:N ratios, and the concentrations of creosote in the compost systems ...

feasibility of waste lime sludge (ls) obtained from acetylene gas production industry wasstudied during co-composting of vegetable waste for enhanced volatile solids reduction. four different trialswere carried out with varying percentage of ls combinations i.e. trial 1, trial 2, trial 3 and trial 4. increasedaddition of waste ls raised the levels of ph in the compost, thereby volatizing the ni...

OBJECTIVE To (i) evaluate food choices and consumption patterns of elementary- and middle-school students who participate in the National School Lunch Program (NSLP) and (ii) compare students' average nutrient intake from lunch with NSLP standards. DESIGN Plate waste from elementary- and middle-school students' lunch trays was measured in autumn 2010 using a previously validated digital photo...

Food processing industry including fruit and vegetable processing is the second largest generator of wastes into the environment only after the household sewage. The generation of biodegradable waste increased linearly with the growth and development of food processing industry. A huge amount of waste in the form of liquid and solid is produced in the fruit and vegetable processing industries i...

Laboratory and pilot-plant composting of garbage mixtures of newspaper and vegetable waste has demonstrated that garbage can be converted to a medium that produces mushrooms (Agaricus campestris) in good yield. Sewage sludge was less satisfactory than newspaper, gumwood sawdust, or vegetable waste as a compost material for growing mushrooms. A sample of commercially produced compost was found t...

Marketing techniques may improve children's vegetable consumption. However, student participation in the design of marketing materials may increase the material's salience, while also improving children's commitment and attitudes towards healthy eating. The impact of student-led design of vegetable promotional materials on choice and consumption was investigated using 1614 observations of stude...

Vegetable waste usually contains high levels of organic matter, moisture and nutrients that make the waste unsuitable for disposal in municipal landfills. Composting of vegetable waste is in practice by many urban local bodies, and therefore, it was composted along with cow dung and sawdust in a 550-L batch scale rotary drum composter. Four different trials of varying waste combinations of vege...

Fruit and vegetable wastes are produced in large quantities in Iran, and constitute a source of nuisance in municipal landfills. The objective of this study was to optimize the applications of anaerobic digestion for the treatment of municipal organic wastes. We studied the effect of organic loading rates on anaerobic digestion of vegetable wastes. The complete-mix, pilot-scale digester with wo...

This study deals with artificial neural network (ANN) modeling a diesel engine using waste cooking biodiesel fuel to predict the brake power, torque, specific fuel consumption and exhaust emissions of engine. To acquire data for training and testing the proposed ANN, two cylinders, four-stroke diesel engine was fuelled with waste vegetable cooking biodiesel and diesel fuel blends and operated a...
