  • Plastics Separation In Compost

    Operators say their number one contamination problem is plastic small, large and in-between - in the compost feedstock and thus in the end product. New study and equipment offer some excellent solutions. An air separation unit from Hawker Corp. is attached to the outfeed conveyor of a screen. Plastic is collected in a tube sock (inset) attached to the fan assembly. PRESSURE in Europe to increase ...

  • 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 ...


  • HPLC separation and detection of bisphenol a (BPA) in plastics

    The BPA or bisphenol A (Figure 1) has become well know over the past year as concerns for its effect on human health and well being have been raised. The concerns over BPA began with baby bottles and spread to include other types of bottles. BPA is used in the production of two very common polymers PVC and Polycarbonate. PVC, Polyvinyl chloride, is used in many different products including ...

  • Recycling of plastic waste by density separation: Prospects for optimization

    A review of existing industrial processing and results of alternative processing investigations for separating solid mixtures and specifically recycling plastic waste by density separation is presented. Media density separation is shown to be fundamental for separation and/or pre-concentration in the recycling of plastics. The current use of static media processes limits the capacity and size of ...

  • Separation tank / Floating tank for separation of different kinds of plastic

    The NEUE HERBOLD – Separation Tank Type TB is used for separation of  plastics with various densities, primarily for film flakes, granulate from  PET bottles and other rigid types of plastics. Depending on the application, floating particles like film falkes or sinking particles like PET bottle flakes are separated from other high density plastics. The standard separation tanks ...

  • Pre-separation of household plastics from EfW plant in-feed case study

    Challenge: Client tendering for large scale Energy from Waste (EfW) facility. Axion asked to provide separation and sorting of plastic fractions in residual household waste. Axion Solution: Axion evaluated volume and mix of plastics in the target waste stream. Modelled range of plant options to remove and separate ...

  • In the Works: Magnetic Plastics

    (from Recycling Today Magazine) Harnessing the power of magnetic currents has long been an effective way to separate and recover scrap metals. Now, researchers are looking at ways to use this same power to improve scrap plastic sorting methods. Scrap plastic comes in the form of production or processing scrap and from post-consumer streams. Production scrap can often be components or ...

  • FLOTTWEG SORTICANTER® for Plastic recycling

    How many times each day do you use something made out of plastic? From a toothbrush to a soda pop bottle, from a grocery bag to a garden hose, plastics are part of our daily life. Needless to mention the huge amount of waste plastics generated in the industry. You probably know that plastics are made from petroleum, a non-renewable resource. When plastics are thrown away, they become part of the ...

  • Time is of the essence in plastics

    Introduction Determining the moisture content in plastics is an important step in the extrusion and molding process of many industrial resins.  Excessive moisture content can lead to microscopic steam pockets that can blister or weaken the integrity of the molded product.  Plastic pellets in a saturated or ‘wet’ state can also mislead buyers of bulk plastic since ...

  • Separation of Nylon 66 (PA 66) From Automotive Shredder Residue (ASR) Plastics by Flotation

    Plastics are the most valuable component of the automotive shredder residue (ASR) waste material making up 30% of the total weight. One promising separation technique, which is able to selectively recover the plastics from ASR, is flotation. It has been demonstrated for a synthetic PA66/ABS/PC system that nylon 66 (PA 66) can be selectively separated by caustic treatment and addition of alcohol ...


  • Milestone moments in plastics recycling history

    Two separate statistical analyses, one published in Europe and the other in the USA, serve to underline the dynamic and international nature of the plastics recycling sector. Both focusing on developments in 2006, the reports reveal significant increases in the collection of post-consumer plastics on both sides of the Atlantic, as well as unabated export ...

  • Operator Strategies : Sorting Out the Plastic

    BETTER BUGS Ideas and products in the Better Bugs category attempt to affect the biological components and biochemistry of processes by altering the mix of microorganisms or enzymes present. After all, biology is the foundation of many, if not most, organics recycling systems. Pyrophiles: The first example of Better Bugs involves pyrophilic organisms, bugs that can take the heat. This example is ...

  • Compostable Plastics And Environmental Marketing Claims

    According to a bottled water survey conducted by Perception Research Services International (PRS) for Brand Packaging published in August 2011, where shoppers were interviewed in person to gain some insights on marketing claims, environmental and recycling messages were misunderstood and not even noticed by a majority of consumers interviewed. In fact, only 50 out of 200 shoppers even noticed the ...

  • The Ubiquitous Plastic Bag — And What To Do

    Each year, Americans consume over 100 billion single use plastic bags, the most ubiquitous of all throwaway items. Their usefulness can be measured in minutes; unfortunately, the waste lingers longer, and can clog sewer lines, create problems in recycling plants, and pollute waterways. However, single use plastic bags are also cost-effective and more durable in inclement weather. Local, state, ...
