  • New ways for Metal Recycling

    REWAVE XRF 3-way-sorting in innovative  “Free-Fall”-design Recycling of metal and aluminium knows no limits because it can be remelted as scrap indefinitely. Metals, however have to be separated from non-metallic impurities, and different metals have to be sorted in pure fractions to be used as secondary raw materials substituting primary resources. Especially when it ...

  • Removal of Hg(II) from aqueous solution using sodium humate as heavy metal capturing agent

    An environmental friendly and economic natural biopolymer-sodium humate (HA-Na) was used to capture Hg(II) from aqueous solutions, and the trapped Hg(II) (HA-Na-Hg) was then removed by aluminium coagulation. The best Hg(II) capturing performance (90.60%) was observed under the following conditions: initial pH of 7.0, coagulation pH of 6.0, HA-Na dosage of 5.0 g L−1, ...

  • Rethinking Packaging

    Packaging—it surrounds almost everything we buy. Think about all the boxes, plastic wrap, six-pack rings, toothpaste tubes, plastic bottles, Styrofoam peanuts, and more we come across every day. Unfortunately, a lot of this packaging either ends up in the trash can or is littered. One way to be responsible is to buy things that don’t have a lot of packaging. If you do buy something ...

  • Coating of Plastic Granules - case study

    In order to increase the production output of extruders and injection moulding machines, the flow and processing characteristics of plastic granules have to be modified. Especially for polyamides (PA) and polystyrene (PS) this occurs by means of powdering (coating) with powder additives. In doing so, two different methods are common. The pure dry mixing of plastic granules with the powder ...

  • Tips and Suggestion for Waste Styrofoam Recycling

    Styrofoam is widely used in a lot of fields, including packaging material, such as food packaging material, express packaging material and electronic products packaging materials. Styrofoam is a rigid foam often found in packaging and take-away containers. But Styrofoam need take more than 1 million years to decompose and it is often not cost-effective to recycle. So ...


  • Effective production of rapid filters with polystyrene granules as a media filter

    In conventional water treatment stations, the filter cleaning is performed with the use of filtered water. To save water and obtain higher production, the use of polystyrene (PS) beads has been proposed as a granular filter element because it is a granular element with a low specific mass. By being lightweight, this material requires a lower water velocity during backwash. The PS beads were ...

  • Investigating the influence of elongated anaerobic feeding strategy on aerobic sludge granulation and characteristics in sequencing batch reactor

    In this research, two sequencing batch reactors (R1 and R2) were operated with different feeding strategies to investigate the effects of elongated anaerobic feeding mode on the granulation process. For this purpose, R1 was operated in a short-feed strategy (5 min) as a reference, whereas an extended anaerobic feeding of 85 min was applied in R2. Results showed that aerobic granules formed in R1 ...

  • Recycling Vs. Landfills and Incinerators – Do Benefits of One Outweigh the Other?

    Believing the 2011 survey results of the U.S Environmental Protection Agency (EPA), the American nationals generate more than 240 million tons of waste every year. Often referred to as Municipal Solid Waste, this waste originates from households, schools, hospitals, and business establishments. This trash material often finds its place in the wasteland, where it is either recycled, trapped in a ...

  • Recycling EPS FOAM With EPS Shredder and Compactor

    Used EPS, also called Styrofoam or expandable polystyrene foam, is light, hygienic and commonly used to pack food, drinks, fragile and deformable goods. Usually, EPS products are 98% air and only 2% PS. It has been a big environmental problem due to the fact that the material is difficult to recycle and costly to transport. Harden Machinery has been dedicated to EPS volume reduction technologies ...
