This study investigates the effects of sieved wastes generated from the brewing industry on lightweight aggregates manufactured with clay. Sludge from a wastewater treatment plant, bagasse and diatomaceous earth were used to obtain the samples. These wastes are usually dumped in landfills, but the current increase in restrictions on dumping and interest in improving the environment make our pro...

background: production of solid waste is the result of the human’s different activities that today has changed a lot in comparison to the past due to the changing life styles and pervasive expansion. in isfahan province lots of wastes are produced daily. due to the importance of the waste and its recycling, the purpose is determining the production scopes of different wastes in order to find a ...

Brick is one of the most common masonry units as a building material due to its properties. Many attempts have been made to incorporate wastes into the production of bricks, for examples, rubber, limestone dust, wood sawdust, processed waste tea, fly ash, polystyrene and sludge. Recycling such wastes by incorporating them into building materials is a practical solution for pollution problem. Th...

This paper deals with the study of radioactive waste generation and their treatment techniques. The wastes that are generated during the front and back end of the nuclear power production are classified are low, intermediate and high level waste. The various existing process for the treatment for the waste like, reprocessing, pyroprocessing, transmutation, and options available for the disposal...

This paper reports the vermicomposting of food industry sludges (FIS) mixed with different organic wastes employing Eisenia fetida. A total of 10 vermicomposting units containing different wastes combinations were established. After 15 weeks significant increase in total nitrogen (N(total)) (60-214%), total available phosphorous (P(avail)) (35.8-69.6%), total sodium (Na(total)) (39-95%), and to...

Several research programs investigated energy crops (aquatic and marine plants, grasses, and woods) and municipal solid wastes (MSW) coupled with anaerobic digestion for generation of renewable substitute natural gas. These programs integrated research on crop production and harvesting, collection of municipal solid wastes, conversion of these feedstocks to methane by anaerobic digestion, and s...

In past two decades waste management has become one of the most important public concern in developing countries. Hospital waste management has become a critical issue as it poses potential health risks and damage to environment. All those wastes which are generated in hospitals or during health care activities carries a higher risk for infection and injury than any other wastes. In the process...

This paper describes the determination of fatty acid composition of coffee, citrus and rum distillery wastes using reversed-phase high-performance liquid chromatography (RP-HPLC). Lipid extracts of the waste samples are derivatized with phenacyl bromide and their phenacyl esters are separated on a C8 reversed-phase column by using continuous gradient elution with water and acetonitrile. The pre...
