Lignocellulosic wastes are abundant, renewable and inexpensive sources of energy. This wastes contains large amount of residual plant biomass which is non edible material obtained from plant cell walls. Biomass could be obtained from crop, domestic liquid fuel, municipal solid waste and agricultural residuals. In nature, cellulose, hemicellulose and lignin are major component of plant biomass t...

The aim of the experiment was to analyze the particular processes (biomass synthesis, oxidation, denitrification and accumulation) during carbon removal from wastewater. The experiment was carried out in a sequencing batch reactor (SBR) in two series with different organic carbon compounds to nitrogen compounds ratio (COD/N). Organic carbon loading of activated sludge was 0.07 g COD/g·d. Organi...

Anaerobic digestion is the breakdown of biodegradable organic material by microorganisms in the absence of oxygen or in an oxygen-starved environment.This technology is superior to the landfilling and also the aerobic composting. The aim of the present study was to examine whether the effluent Volatile Fatty Acids from the anaerobic acidogenesis of the food waste can be used du to its high valu...

Composting of waste plant materials and its use in agriculture and landscape sites is an environmental friendly way of reducing waste material and conserving the environment. In this perspectives a survey has been performed at the Dubai based International Center for Biosaline Agriculture to compost the plants based waste material (lawn cuttings-grass) to compost. The material was inoculated wi...

The possible use of municipal solid waste compost (MSWC) in the production of marigold and basil seedlings examined. Six medium prepared from commercial peat (CP) and MSWC (0, 15, 30, 45, 60, and 100% v/v). There was not any plant growth when MSWC used alone (100%). The addition of MSWC in low content (15% and 30%) improved seed emergence for marigold and basil respectively, while greater conte...

A new system dynamics tool, T21-Ohio, was developed to support integrated and comprehensive development planning at the state level. Based on the Threshold 21 (T21) framework, T21-Ohio provides insights into the potential impacts of energy and environmental policies across a wide range of sectors, and reveals how different strategies interact with one another to achieve planned goals and object...

Biomass gasification processes are more commonly integrated to gas turbine based combined heat and power (CHP) generation systems. However, efficiency can be greatly enhanced by the use of more advanced power generation technology such as solid oxide fuel cells (SOFC). The key objective of this work is to develop systematic site-wide process integration strategies, based on detailed process sim...

Waste disposal is one of the pressing problems.Millions of tons of municipal solid waste, hazardous/industrial wastes and agricultural wastes are handled daily throughout municipal areas. Each municipality confronts great challenges in disposing of its wastes in an efficient, cost effective and environmentally safe manner.Landfills in metropolitan areas are becoming full, and new ones are more ...
