  • Are you recycling polystyrene the right way? Don’t risk the heavy fines

    While there’s a European-wide drive to recycle more polystyrene, some forms of it contain a flame retardant that is hazardous to human health and the environment. The idea of the circular economy is a compelling one, and it’s driving recycling policies worldwide across industries. There is more focus than ever is on the complete lifecycle of products, including packaging, vehicles and ...

  • 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 ...

  • 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 ...
