  • 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 ...

  • Economics of super absorbent polymers and waste stabilization

    Economics of Super Absorbent Polymers & Waste Stabilization The use of super absorbent polymer (superabsorbent polymer or SAP) in waste stabilization offers many advantages over more conventional absorbents. These advantages include: • Minimal increase in waste volume or weight • Lower transport fees due to less loads • Lower total landfill disposal fees due since waste volume has not ...

  • Success with water-soluble polymers

    An industrial waste treatment system in Texas used AQUACLEAN / ACF-32 in their plant to reduce BOD, Ammonia, TOC, and TSS. This industrial site was processing water-soluble polymers that were proving to be difficult for their activated sludge system. In the existing system design, the influent stream is first treated by a pH adjustment to a level of 12 or higher, and then is later anaerobically ...

  • Hydro Polymers: Searching for a More Sustainable PVC

    Over the last five years, the European PVC industry has been forced to reassess the environmental impact of its products in the face of continuing pressure from environmental groups, governments and end users. Hydro Polymers, one of two PVC manufacturers in the UK, is forging ahead of its competitors through a partnership with sustainability consultancy The Natural Step. The company is launching ...

  • Influence of nanoparticles on the polymer-conditioned dewatering of wastewater sludges

    The effect of using small-scale, high surface area, nanoparticles to supplement polymer-conditioned wastewater sludge dewatering was investigated. Aerobically digested sludge and waste activated sludge sourced from the Hunter Valley, NSW, Australia, were tested with titanium dioxide nanoparticles. The sludge samples were dosed with the nanoparticles in an attempt to adsorb a component of the ...

  • Determination of Polychlorinated Biphenyls (PCB) and Phthalates in Waste Polymer Samples intended for Mechanical Recycling

    The purpose of this study was to determine the levels of polychlorinated biphenyls (PCBs) and phthalates in homogenized polymer samples from polymer waste streams using two different pressurized fluid extraction instruments (ASE and SpeedExtractor). Both extraction methods showed very similar results. Measured PCB levels were in the lower and sub ppm range. Calculated total PCB levels using the ...

  • Assessment of the environmental advantages and drawbacks of existing and emerging polymers recovery processes

    The production and consumption of plastics is increasing rapidly; there are materials outpacing GDP growth and taking over new markets. Nevertheless, only 39% of total collectable waste plastics are being recovered at present. In May 2003, the Commission adopted a Communication towards a Thematic Strategy on the Prevention and Recycling of Waste , which investigates ways to promote recycling ...

  • A molecular imprinted polymer based sensor for measuring phosphate in wastewater samples

    Phosphate detection in water samples is still completed using colorimetric standard methods, which have a number of disadvantages, to such as being time consuming, requiring filtration, a number of different reagents, frequent calibration and proper disposal of waste chemicals generated. Hence, a simple cost effective analytical method and instrumentation is highly desirable to aid the ...

  • Case-study - Shaping a sustainable future for synthetic polymer production

    Consciousness of climate change mitigation and increasing costs of raw materials for energy production are set to shape the future of polymer production. The Dream Products project aims to explore the potential to partly replace petroleum with CO₂ as a base raw material for polymers with the overall goal of bringing CO₂ based products to market. The climate change issue ...

  • Synthetic organic polymer fouling in municipal wastewater reuse reverse osmosis

    A full scale waste water reuse plant suffered from irreversible fouling of the reverse osmosis (RO) membranes. The major suspect of fouling is cationic organic polymers applied in the wastewater sludge treatment. Thus, the purpose of this research is to study the effect of six cationic polymers, applied in the plant, on RO membrane performance. The filtration and adsorption experiments with 4 mg ...

  • Testing the barrier performance of metallized polymer films for permeation of oxygen and water vapour

    General Vacuum in Lancashire, now part of the Bobst Group have been designing and building large industrial vacuum roll coaters for use in optical, electrical and general packaging applications since 1996. Aluminium metallized polymer films can be used in packaging applications where there are a number of requirements including barrier protection (WVTR, OTR etc.).  This type of packaging has ...

  • Leachate and Hydrolysate Content of Food Grade Polymers using Microwave Preparation with Non-Contact Temperature & Pressure Control

    Food SAFETY is a primary concern for manufacturers and consumers World-wide. While there is always concern for the Food PRODUCT itself… from either Microbial or Chemical contamination… there is also a need to preserve Food for storage and shipment, and the desire to minimize packaging waste, and many Food items are sold as “ready-to-eat” products. Now we must concern ourselves with the ...

  • Winning With Zero Waste

    In the business of professional and collegiate sports, with top priority on championships, player injuries, and filling stadium seats, attending a meeting with Martin Tull, Executive Director of the Green Sports Alliance (Alliance), seems like a walk in the ballpark. “When we speak to potential members, we often say, ‘Would you like to know how other teams are saving millions of ...

  • Electrostatic Separation of Mixed Plastics Waste

    A major environmental problem is mixed plastics waste. Because of the incompatibilities of the properties of different polymers, mixed waste is either land filled or reused in low value applications such as plastic wood. The barrier to economic re-use of these materials is separation into pure components. Recycled pure plastics can be used in place of virgin material and thereby much of the ...


  • Ultrasonic Waste and Sludge Treatment

    Biogas is generated from sources, such as municipal organic waste, sewage sludge, muck or manure. Ultrasonication improves the digestibility of such organic material leading to more biogas and less residual sludge. Biogas is a byproduct of the decomposition of organic matter by anaerobic or aerobic bacteria. It consists primarily of methane, carbon dioxide and hydrogen sulfide. This makes biogas ...

  • Environmental Sensors in Waste Management

    Issue: As part of an increasing sentiment among European consumers that environmental protection is important, concern about the impact of landfill is growing. Sensor technology makes it possible to measure and control inputs to landfill sites and pollutants arising from them. However, the exploitation - or uptake - of such technology has been lower than expected in the waste management sector. ...
