Sea shores of Gilan Province is one off the biggest tourist attractions in Iran. This area have valuable forests and grasslands. In addition it provides significant amount of corps like rice, tea, olive. Considering this facts, environmental protection of this area must be priority for national government. However waste management instruction have been ratified in Iran, there isn’t any specific...

The incorporation of recycling, which is the production of raw materials from old buildings and devices, is an increasing trend in industries worldwide. This increase in recycling is motivated by the conservation of energy and environmental resources, in particular, the decrease of carbon dioxide and green house gas emission by the intensive burning during various technological processes. The p...

the adsorption properties and mechanics of selected endocrine disrupting compounds; 17 β-estradiol, 17 α – ethinylestradiol and bisphenol a on locally available black tea leaves waste and granular activated carbon were investigated. the results obtained indicated that the kinetics of adsorption were ph, adsorbent dose, contact time and temperature dependent with equilibrium being reached at 20 ...

Heavy metal remediation of aqueous streams is of special concern due to recalcitrant and persistency of heavy metals in environment. Conventional treatment technologies for the removal of these toxic heavy metals are not economical and further generate huge quantity of toxic chemical sludge. Biosorption is emerging as a potential alternative to the existing conventional technologies for the rem...

An industrial plant consists of an input of energy, raw materials and labor and an output of products, waste energy and waste materials. If raw material and labor costs are relatively fixed, a reduction in the plant’s energy costs and waste materials are the two best means of improving profitability. This project specifically evaluates cogeneration opportunities as a means of substantially redu...

Interstitial Fluid Displacement (IFD) is a new and novel method for separating cesium from saltcake waste. It was identified by reevaluating fundamental factors of the saltcake recovery system, such as physical and chemical properties of saltcake, experience from other technical disciplines and industries, processing rate requirements, process safety requirements, and use of proven-successful p...

Waste management generated from a Chemical-Looping Combustion (CLC) plant using copper-based materials is analyzed by two ways: the recovery and recycling of the used material and the disposal of the waste. A copper recovery process coupled to the CLC plant is proposed to avoid the loss of active material generated by elutriation from the system. Solid residues obtained from a 10 kWth CLC proto...
