The plantation of fast growing trees in contaminated sites, in combination with the use of organic wastes, could partially solve a dual environmental problem: the disposal of these wastes and the improvement of soil quality in these degraded soils. This study evaluated the effects of two compost on the quantity and quality of Paulownia fortunei biomass and on syngas production by biomass gasifi...

Convenience food manufacture generates considerable waste through poor planning of production. This problem is particularly acute for products that have a very short shelf life and will be disposed of as waste should their shelf life expire. Chilled ready-meals are convenience foods with relatively short shelf lives and volatile consumer demands; their manufacture is based on forecasted volumes...

The environmental performance of industrial anaerobic digestion (AD), pyrolysis, and integrated system (AD sequence with pyrolysis) on food waste treatment were evaluated using life cycle assessment. The integrated treatment system indicated similar environmental benefits to AD with the highest benefits in climate change and water depletion in addition to the increased energy generation potenti...

minimizing their wastes. The concept of such minimization, recycling, zero discharge (all aspects of the same reuse philosophy) is appealing and straightforward. The reality often is not: In some cases a highly organic wastewater, as from a paper mill or a food processing facility, has to be converted to a highpurity stream. As if this is not challenge enough, such treatment must be consistent,...

Overview Description of real life problem Motivation for choosing a multiple objective model Multiple objective model (decision variables, objectives, constraints) Technique used to solve the problem Analysis of results Opinion about the proposed model and solution approach Description of the real life problem We consider a waste incineration plant Input : Waste (cardboard, wood, glass, food wa...

Research was conducted to evaluate the feasibility of producing methane gas from combined segregated municipal and agricultural waste. The combination of the two wastes resulted in sufficient nutrient value and bacterial diversity to improve the biodegradability of cellulose and increase the efficiency of gas production from the combined wastes. The feedstock included municipal solid waste with...

Besides their traditional food usage, mushrooms can be used as a source of many pharmacologically active compounds, especially polysaccharides. Wastes left over in the edible mushroom farms such as Agaricus bisporus (white button mushroom) can also become free and alternative source of chitin-chitosan materials, beside the traditional industrial source shellfish waste materials. Chitosan, a nat...

The abundance of organic solid waste throughout the world has become a common issue that needs complete management at every level. Also, the scarcity of fuel and the competition between food and substance as an alternative to a petroleum-based product has become a major problem that needs to be properly handled. An urge to find renewable substances for sustainable development results in a strat...

The principal sources of chlorine in the MSW feed to WTE power plants are food wastes (e.g., wheat, green vegetables, melon, pineapple), yard wastes( leaves, grass, etc.), salt (NaCl), and chlorinated plastics (mostly polyvinyl chloride). Chlorine has important impacts on the WTE operation in terms of higher corrosion rate than in coal-fired power plants, formation of hydrochloric gas that must...
