  • 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 ...

  • 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 ...

  • Reverse Osmosis and Nanofiltration Membrane Filtration Systems: Common Problems and How to Fix Them

    Reverse osmosis (RO) and nanofiltration (NF) are membrane filtration technologies that are designed to remove solute ions and molecules from a pretreated liquid stream. Well-designed RO/NF units are compact and demand relatively little maintenance, making them an attractive alternative to conventional treatment trains. Even despite the merits of today’s efficient RO/NF technologies, it pays ...

  • 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 ...

  • Composting of Municipal Solid Waste through chemical pretreatment

    Composting is one of the viable options for bioprocessing of Municipal Solid Waste (MSW). An important aspect of the composting process is the period required for attaining stability/maturity, and the quality of compost. In order to enhance the rate of degradation and improve the quality of compost, several pretreatments on MSW were investigated. Chemical pretreatment with low strength NaOH ...

  • 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 ...


  • 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 ...

  • Comparing Capacity Expansion and Waste Minimization Options at a Chemical Manufacturing Facility

    ABSTRACTIndustrial wastewater treatment facilities that are nearing their capacity limit often have a relief option that typically is not available to municipal treatment facilities. That option is to reduce waste loads coming from the production areas by optimizing manufacturing processes so that less waste is generated per pound of product made. In making the decision between reducing waste ...

  • The physical, chemical and microbial characteristics of biodegradable municipal waste derived composts

    A comparative study of the physical, chemical and microbial properties of 12 composts sourced from United Kingdom commercial composting plants was carried out. The aim was to ascertain whether these composts could be used as growing media or for application to agricultural land. The composts were produced from either source segregated biodegradable municipal waste (BMW) or mixed municipal solid ...
