  • Mechanical Biological Treatment (MBT): The new kid on the UK waste management block

    Waste management in the United Kingdom (UK) has undergone a revolution in the past 20 years. In 1990, the UK landfilled more than 90 percent of its municipal solid waste (MSW), incinerated about 8 percent and recycled the remaining 2 percent. It had one the highest landfill rates in Western Europe and one of the lowest recycling rates, reflecting the UK’s mining traditions and aggregates ...

  • On the pre–treatment of municipal organic waste towards fuel production: a review

    Lignocelluloses are the main constituents of municipal organic waste (MOW). In order to increase the production of fuels, via fermentations, the enzymatic hydrolysis is the first step towards a valorisation process. It is well–known that the hydrolysis of lignocelluloses is not very effective because of the high stability of the constituents. In this respect the pre–treatment of MOW is necessary ...

  • Biological water treatment effective in Saddle Lake

    Three transparent pipes connected to a network of hoses and gauges stretch from the floor to the 14-foot ceiling in a back room of the Saddle Lake water treatment plant. Water burbles through the pipes, mixing with a material that looks like black sand. The particles are actually expanded clay aggregates that provide the surface needed for water-cleaning bacteria to live on. The bacteria remove ...

  • Ex Situ Biological Treatment for Soil, Sediment, and Sludge

    The main advantage of ex situ treatment is that it generally requires shorter time periods than in situ treatment, and there is more certainty about the uniformity of treatment because of the ability to homogenize, screen, and continuously mix the soil. However, ex situ treatment requires excavation of soils, leading to increased costs and engineering for equipment, possible permitting, and ...

  • Reclamation of a mine contaminated soil using biologically reactive organic matrices

    Organic residues such as sewage sludge, biowastes and composts are increasingly used in land rehabilitation because they can improve the physical, chemical and biochemical properties of soil, and reduce the need for inorganic fertilization.
