SUMMARY: In Europe almost 80 million tons of waste are annually combusted in Waste-to-Energy plants. Solid residues generated thereby contain altogether about 69,000 t/a of Zn, of which more than 50 % accumulates in air pollution control (APC) residues. Recent research activities aiming at Zn recovery from APC residues resulted in a large scale Zn recovery plant at a Swiss waste incinerator. By...

background: based on the economical and environmental concepts, the main purpose of the industrial waste management is reducing the production of these materials which is accessible by developing strategies of reuse, waste recycle and upgrading the technologies. accurate investigation of the quality and quantity of the industrial waste is the basis of the industrial waste correct management. th...

Chloride is commonly assayed in the clinical laboratory with a mercuric thiocyanate reagent. For example, the Technicon chloride color reagent for the SMA 6/60 contains 400 mg of Hg per liter (ppm), and the waste solution contains 130 mg/L (confirmed by analysis), generated at the rate of 300 mL/h. In our laboratory we accumulate 60 L of waste per month, containing almost 10 g of Hg. It is unde...

the effects of ensiling alhagi with waste date palm on rumen parameters and microbial protein synthesis in kermani sheep were investigated. 100 kg alhagi with 20 kg waste date palm were mixed and ensiled for 45 d. the experimental diets containing 0, 7, 14 and 21% alhagi with waste date palm silage. four male kermani rams were used in change over design with four 21-days period. ensiling alhagi...

There is growing environmental concern with the methods of waste disposal used for handling hazardous materials in the metal finishing industry. A resulting need exists to develop and implement the best existing and potential technologies for waste minimization and resource recovery. The objectives of this study were to identify and briefly describe both existing and potential future methods fo...

Au-Ag noble metal wastes represent a wide range of waste types and forms, with various accompanying metallic elements. The presented leaching strategy for Au-Ag contained in circuit boards (PCBs) aims at gaining gold and silver in the metallic form. Application of the proposed ammonium thiosulphate leaching process for the treatment of the above mentioned Au-Ag containing wastes represents a pr...

With the growing population rate, the amount of waste being produced is also increasing at a very faster rate. It is also posing a very serious problem at the municipal level to manage the wastes being dumped everywhere as landfill waste. So, it is very crucial to have some system to manage waste automatically which is currently not there. Prime Minister Modi’s mission of Swaccha Bharat Abhiyan...

Autoimmune nephritis triggered by metallic ions was assessed in a Long-Evans rat model. The parameters evaluated included antinuclear autoantibody production, kidney damage mediated by immune complexes detected by immunofluorescence, and renal function tested by retention of nitrogen waste products and proteinuria. To accomplish our goal, the animals were treated with the following ionic metals...
