  • Recovery of aluminium alloys and some valuable salts from Spent Bottle Covers

    This work provides a method to prepare standard Al-alloy(s) and some salts of market value from Spent Bottle Covers (SBCs). Aluminium covers were separated from others made of iron or plastic by magnetic and flotation techniques. The aluminium covers were melted under flux. Metals went into the slag were leached using hydrochloric acid. Results obtained revealed that the removed paint decomposed ...

  • Recovery of phosphorus and aluminium from sewage sludge ash by a new wet chemical elution process (SESAL-Phos-recovery process)

    The potential of a new wet chemical process for phosphorus and aluminium recovery from sewage sludge ash by sequential elution with acidic and alkaline solutions has been investigated: SESAL-Phos (sequential elution of sewage sludge ash for aluminium and phosphorus recovery). Its most innovative aspect is an acidic pre-treatment step in which calcium is leached from the sewage sludge ash. Thus ...

  • Energy conservation in aluminium foundries by waste heat recovery from solidifying molten metal

    This paper presents a unique attempt to preheat the raw materials by recovering the waste heat from solidifying molten metal in shape castings of aluminium using sand moulds. Finite element analysis of the problem using ANSYS has also been done, results of which show satisfactory agreement with the experimental results. By using this preheating method, it is proved that around 16% of heat ...

  • Treatment of eutrophic lake water and phosphorus recovery by reusing alum sludge and/or wood

    Treatment of eutrophic lake water was investigated, when alum sludge and/or wood were used as the media for laboratory-scale filtration. Process 1 consisted of Column 1 with wood and Column 2 with alum sludge in series, and Process 2 of Column 3 with alum sludge. The filtration velocity was 0.45 and 0.91 m/d for 49 days each. Both processes removed suspended solids and total phosphorus well ...

  • Aqua Regia Digestion for Trace Metals Recovery from Soil and Water

    Metals are regulated because they have the potential to harm human health and the environment. Unlike organic chemicals, metals are not degradable and have a greater tendency to accumulate. According to Environmental Protection Agency metals and metalloids of primary interest are: Silver (Ag), Aluminium (Al), Arsenic (As), Boron (B), Barium (Ba), Beryllium (Be), Cadmium (Cd), Cobalt (Co), ...

  • Sewage pre-concentration for maximum recovery and reuse at decentralized level

    Pre-concentration of municipal wastewater by chemically enhanced primary treatment (CEPT) was studied under controlled laboratory conditions. Both iron and aluminium-based coagulants were examined at gradually increasing concentrations (0.23, 0.35, 0.70 and 1.05 mmol/L). The CEPT sludge generated from different coagulation experiments was digested in batch anaerobic reactors, while the ...

  • Recovery and Reuse of Filter Backwash Water: Coca-Cola Amatil

     Background The Coca Cola Amatil (CCA) Northmead plant in Sydney was established in 1972 and manufactures a wide range of world recognised Coca-Cola trademark soft drink products, such as Sprite, Fanta, Lift and Coca-Cola. The Northmead plant has one aluminium can line and two plastic PET bottle lines. It produced over 250 million litres of soft drink in 1995. ...


  • Cost-Efficiency of Packaging Recovery Systems: The Case of France, Germany, the Netherlands and the United Kingdom

     Context and Objective of the Study In the last years, the European Community has launched a number of initiatives aimed at increasing recycling and recovery of certain waste streams. Among these, the Packaging and Packaging Waste Directive (94/62/EC) had to be implemented into national law by 30 June 1996. In spite of delays in several countries, legislation is now in place in all Member ...

  • Coagulation–flocculation for lignin removal from wastewater – a review

    Industrial discharge has tremendously increased inorganic pollutants in water bodies all over the world. Paper and pulp effluent is included in one of the most pollution generating discharges containing complex chemical compounds such as lignin. For clean and healthy water resources, the recovery of lignin from wastewater from the paper and pulp industry is of high importance. Available chemical ...

  • Landfill sites – home to buried treasure!

    Recent studies have found that landfill sites are most certainly filled with huge volumes of valuable metals. According to a study carried out by Cranfield University, scientists analysed samples from up to 30 metres deep from four different landfill sites. Large objects where removed and the samples were analysed for the content of rare earth metals and other valuable metals. Results indicated ...
