  • Climate change impacts of food waste diversion to anaerobic digesters

    Treating food waste (FW) by anaerobic digestion to recover biogas and biofertiliser is a fantastic opportunity. The biogas is renewable, base-load, non-fossil energy. Using the digestate on land as biofertiliser completes nutrient cycles and conserves soil organic matter. The Part-503 rules protect health and the environment. Existing sludge digesters can be ‘turbo-charged’ by retrofitting ...


  • Vermicomposting of dewatered sludge from pulp and paper mill

    The present paper is aimed at conversion of dewatered sludge from pulp and paper mill into value added product through vermicomposting. The dewatered sludge was blended with cow dung and food processing waste in five different combinations R1 (1.5), R2 (1 + 0.24 + 0.26), R3 (1 + 0.34 + 0.16), R4 (1 + 0.41 + 0.09) and R5 (1 + 0.46 + 0.04) for utilisation in vermicomposting using Eisenia fetida. ...

  • New processes for the improvement of sludge digestion and sludge dewatering

    INTRODUCTIONThe examination of numerous sewage sludges from municipal wastewater treatment plants leads to the conclusion that on the one hand dewaterability of these sludges worsens and that on the other hand dewaterability of sludges becomes more and more important due to increasing disposal costs. Especially wastewater treatment plants with inflows from the food processing industry often face ...

  • Waterways and ponds contaminated with pulp & paper PCBs are contained & dewatered using Geotube container, providing an economical environmental solution - Case Study

    Abstract: Polychlorinaled biphenyls (PCBs) were unknowingly generated in ihe waste of some of the pulp and paper systems, a known carcinogen in animals and a probable carcinogen in humans. PCBs are stable, man-made compounds. They absorb heat and do not easily break down. Because of these properties, they have been widely used in electrical equipment, hydraulic fluids, fire retardants, ...

  • Energy from waste: the recycling of limed fleshings

    Leather products have been around a long while - there are those who claim that it is the second oldest business in the world. Going back a few millennia, when our earliest ancestors decided that sitting on hard rock was not a soft option, they turned to other materials in order to create more comfortable seating, as well as warmer bedding and improved clothing. Animal skins became the fabric ...

  • The effect of mixing conditions on anaerobic digester performance

    The basic principle of aerobic wastewater treatment is the conversion of some parts of organic matters to biomass and this causes production of excessive sludge in aerobic processes. This excessive sludge is withdrawn from time to time to prevent accumulation of biomass in aeration basin. In most cases, this sludge requires the stabilization before the dewatering and disposal. Different processes ...

  • Design and development of decentralized water and wastewater technologies: a combination of safe wastewater disposal and fertilizer production

    Modern wastewater treatment plants are often inappropriate for communities in developing countries. Such communities lack the funding, resources and skilled labour required to implement, operate, and maintain these plants. This research was conducted to investigate and establish an appropriate wastewater treatment system for the district of Gunung Kidul, Indonesia. Due to its lack of water during ...

  • Potential biogas production from sludges and msw in Uruguay

    Sewage treatment Montevideo's sewage is disposed into the sea by means of an outfall. Nevertheless as there are a lot of cities that are not on seashore, and most of these cities are discharging their effluents into rivers without proper treatment, a more strict sewage treatment must be done in order to achieve the discharge standards. For the 1,780,000 inhabitants the current sewage coverage is ...

  • Bioremediation of Effluent the Pulp and Paper Industry

    The treatment of industrial effluent from the paper manufacturing facilities in British Columbia is a major concern because the effluent is discharged into prime salmon habitat in the marine environment (Cross, 1994). High levels of biological oxygen demand (BOD) in the effluent reduce the dissolved oxygen (DO) available to species in the marine environment. In 1988, the Federal Department of ...
