  • Pyrolysis

    Introduction: Pyrolysis is formally defined as chemical decomposition induced in organic materials by heat in the absence of oxygen. In practice, it is not possible to achieve a completely oxygen-free atmosphere; actual pyrolytic systems are operated with less than stoichiometric quantities of oxygen. Because some oxygen will be present in any pyrolytic system, nominal oxidation will occur. If ...

  • Resource treatment of HPF coking desulphurisation waste solution: composition and characteristics of pyrolysis

  • Method of low temperature pyrolysis as an answer for PCBs utilization.

    When people buy new computers, TV-sets or trendy mobile phones they do not think much about the future of substituted models. In a consumer society where devices are changed due to their obsolescence rather than break down the problem of pollution by e-wastes becomes more relevant. Disposal of printed circuit ...

  • Pyrolysis properties of municipal sewage sludge with ZnCl2 activation under the N2 atmosphere

    The municipal sewage sludge with ZnCl2 activation was pyrolysed to obtain useful porous adsorbents. The thermogravimetric analysis and FTIR methods were used to work out the properties of dried sewage sludge with ZnCl2 activation from the Changsha secondary wastewater-treatment plant. The experimental results showed that three stages of weight loss were observed under the heating rates of ...

  • Characterization of biochar prepared from slow pyrolysis of Jordanian olive oil processing solid waste and adsorption efficiency of Hg2+ ions in aqueous solutions

    Solid waste from Jordanian olive oil processing (OOSW) was used to prepare biochar samples by slow pyrolysis at terminal temperatures of 350, 450, 550 and 630 °C; henceforth known as BC-350, BC-450, BC-550 and BC-630, respectively. These samples were characterized by Fourier transform infrared spectroscopy, scanning electron microscopy and X-ray diffraction, ash content, moisture content and ...

  • Staged Thermal Treatment Combined With Pyrometallurgical Smelting Producing Energy and Products From Waste

    Incineration of waste is considered as a state-of-the-art technology. However staged gasification in combination with pyrometallurgical smelting is ready for market introduction and offers principal advantages. These are higher efficiency (up to 35% electricity), efficient and cheaper fuel gas cleaning (less emissions), high quality secondary products (synthetic basalt), high input flexibility, ...


  • Emerging Waste Conversion Technologies

    Today, people and companies are more aware and concerned about the environment than ever before. Everyone is looking for ways to reduce waste or convert organic waste into something more useful. The Federal Government has introduced a renewable energy policy and is continuing to fund for new waste conversion technology. It is now important for local governments to portray their cities and towns ...

  • Determining the viability of a waste-to-energy plant in Africa

    Nick Mannie, Aurecon’s waste expert, was invited to deliver a keynote presentation at the African Waste Week conference in early September at the Cape Town International Convention Centre in Cape Town, South Africa. Mannie discussed the development and execution of robust feasibility plans to determine the  ...

  • Is Waste Going to be Our Apocalypse Without a Noah’s Ark to Save Us?

    Human beings have been dumping waste in water, including the ocean, since before the Agricultural Age. The Industrial Age brought with it new materials to dump, chemical wastes and by-products. Some materials are dumped into rivers and find their way to the ocean by running downstream. Other materials are dumped directly into the ocean from boats. Plastic is a harmful pollutant that does not ...

  • Evaluation of the energetic potential of sewage sludge by characterization of its organic composition

    The composition of sewage sludge and, thus, its energetic potential is influenced by wastewater and wastewater treatment processes. Higher or lower heating values (HHV or LHV) are decisive factors for the incineration/gasification/pyrolysis of sewage sludge. The HHV is analyzed with a bomb calorimeter and converted to the LHV. It is also possible to calculate the heating value via chemical ...

  • In Situ Solidification/Stabilization

    Introduction Solidification/stabilization (S/S) reduces the mobility of hazardous substances and contaminants in the environment through both physical and chemical means. Unlike other remedial technologies, S/S seeks to trap or immobilize contaminants within their 'host' medium (i.e., the soil, sand, and/or building materials that contain them), instead of removing them through chemical or ...
