  • Oil Recycling - Case Study

    The problem: Waste oil recycling contributes very much to climate protection through (CO2) energy saving. Compared to the production of base oil the re-refining of waste oil uses 34 % less resources. In the sixties the German government was subsidising the re-refining of waste oil. Because of that the use of waste oil as a fuel was neglected. The used oil re-refining is the ...

  • Scrubber Removes Grease and Particulates from Air Exhaust

    Operating Issue A food-industry leader in Alabama operates several pork-sausage cookers that exhaust over 4,000 ACFM of moisture and pork grease. The operator installed Electrostatic Precipitators (ESPs) to treat the exhaust but these systems performed poorly and generated high maintenance and operating costs. Additionally, these systems were antiquated and required significant capital ...

  • Crumbling Concrete Water Networks Linked to Common Water Treatment Additive

    Concrete distribution and sewer networks are being corroded at an alarming rate partly because of a commonly used additive in the domestic drinking water and wastewater treatment process according to published reports in the journal Science. In countries throughout the world from industrialized nations like Australia and the USA to developing nations like Colombia, Ghana and the Philippines, the ...

  • Tire Shredding: Alternatives to Landfills

    For many reasons, whole tires pose a major problem to landfills. The most obvious is the inefficient use of space. The actual rubber of a tire takes up only a small fraction of the space a tire occupies, and the rest of the space is wasted. A less obvious but far more serious problem is that tires may trap methane gasses when buried with other garbage in landfills. When this happens, the tires ...

  • From Waste in Anodising Plant to New Chemical Product in Sewage Treatment Plants

    Aluminium containing caustic soda used as a pickling agent in the pre-treatment of aluminium before anodising and aluminium containing sulphuric acids used as electrolytes for the formation of oxide layers in anodising plants can be utilised in municipal sewage treatment plants to reduce phosphates and improve precipitation. From the anodiser's point of view, these products are spent once they ...


  • Chemical production and characterisation of activated carbon from waste 'coffee grounds'

    Activated carbon was prepared from ground–coffee in this study. Experimental results reveal that for the ratio (0, 1 ÷ 0, 3) of coffee grounds to activating agents (ZnCl2, H3PO4) has not noteworthy influence. The rise temperature and carbonisation time respectively, in the interval of 500–700°C and ...

  • Cleaner Production in a Czech Chemical Company

    Overview Bochemie Bohumín Ltd. is the parent company of the Bochemie Group. Since it was founded, it has worked to meet health, safety and environmental requirements: for example by adhering to the chemical industry's Responsible Care programme. One of the most important steps it has taken so far to improve its environmental performance has been to introduce Cleaner Production (CP) in its ...


  • Chemical Spill Response Products & Procedures

    The current political and world climate has forced the Emergency Response Community to take a closer look at the number of potential hazards that they may be called upon to deal with. Of particular concerns are the response to terrorist and/or chemical incidents. Depending on the type of event, responders may be faced with a myriad of challenges and onsite dangers. With a chemical release, the ...

  • Biochemenergy: a project to turn an urban wastes treatment plant into biorefinery for the production of energy, chemicals and consumer's products with friendly environmental impact

    Urban bio-wastes (UBW) contain soluble bio-organics (SBO) with excellent surfactant properties are proven or expected to perform as bio-based products for use in chemical and environmental technology, in agriculture and in animal husbandry as well as or better than commercial synthetic products. On these basis, UBW are proposed as renewable sources of a wide number of products with potential sale ...

  • Waste Reduction and Chemical Minimisation: Oxford Panels

    A program involving recycling, waste reduction and waste treatment, is saving Oxford Panels around $1,000 annually on waste removal cost alone. A 30% saving on the cost of raw materials such as thinners and sandpaper, has also been recorded. Importantly, staff morale has increased. They like the reduction in chemicals and pollutants in their workplace and take pride knowing they are actively ...


  • Chemical Recycling of Plastics Waste (PVC and other resins)

     Introduction For several years, debate has raged about the plastic PVC. Industry and environmentalists contend with each other virtually around the world. The environmentalists pursue a ban, industry aims to improve its environmental performance and believes that from an overall viewpoint there is no reason for such far-reaching measures against their material. In this context, the material ...


  • Estimating evolution of δ13CH4 during methanization of municipal solid waste based on chemical reactions, isotope accumulation in products and microbial ecology

    Natural isotopic composition in substrate may be used to reveal the metabolic pathways of substrate transformation by microbial community. In this paper, a change in δ13CH4 during methanization of reconstituted municipal solid waste was described using a mathematical model based on stoichiometric chemical reactions, equation for the 13C isotope accumulation in products at the low natural C13/C12 ...

  • Investigation of benefit of using coal wastes in cement production

    Waste disposal in coal preparation plants leads to serious environmental problems. These wastes usually contain about 20% carbon, and the composition of the remaining ash is similar to clay. Addition of these wastes to cement clinker raw material utilises carbon as a source of energy. In this investigation, the effect of addition of these waste materials to the raw materials used in cement ...

  • High-strength wastes boost biogas production

    Water and wastewater treatment plants (WWTP) are significant consumers of energy. The U.S. Environmental Protection Agency estimates the industry uses the equivalent of 56 billion kilowatt hours (kWh) of electricity, representing three percent of the nation’s energy consumption, and is responsible for creating 45 million tons of greenhouse gas emissions each year. Energy intensive processes, such ...
