Air filter system prevents emissions
of microplastics into the environment
Eicklingen/Lower Saxony. The technology of the new sorting and recycling plant being built by Source One Plastics in Eicklingen, Lower Saxony, is based on an innovative dry mechanical processing processing method for plastics. The reason for the dry processing of the so-called post-consumer waste is firstly the resource-saving energy efficiency and secondly the complete elimination of fine dust. the complete elimination of fine dust and microplastic particles during thermal recycling. At the beginning of December, Schulz und Berger installed an air filter system tailored to these requirements in the newly constructed recycling hall. It prevents fine dust or microplastic microplastic particles from being emitted into the environment. With the installation of the air filter system, the final construction phase of the advanced sorting and recycling plant is drawing to a close. Cold commissioning will start in January 2024. The first Source One Plastics plant will go into regular operation at the end of February 2024. February 2024.
Conventional recycling processes use water to clean plastic waste. plastic waste. Washing and drying as well as washing water treatment lead to an enormous energy consumption. Dry mechanical processing of the waste reduces energy consumption by up to up to thirty percent. It also prevents microplastics from being emitted into the environment, as the plastics plastics have no contact with water and therefore no microparticles can be rinsed out. “We have rearranged the entire waste treatment process,” says Kai Hoyer, Managing Director of Source One Plastics GmbH. “With the help of differentiated classification and upstream near-infrared sorting, we are able to clean the plastic mechanically. This is done by the surface contaminants and organic matter from the source material under high pressure. are rubbed off.”
The microparticles produced during the dry cleaning of the plastic are removed using a constant vacuum in the recycling hall are sucked directly into the air filter system and then for incinerated in a controlled manner to generate heat. “This also allows us to create optimal working conditions for for our employees,” says Kai Hoyer. “Our high-performance dust filters clean the air down to a residual dust content of less than three milligrams per cubic meter. This means that we fall below the limit of 10 milligrams per cubic meter by more than two thirds.”
The installed jet bag filter from Schulz und Berger is 24 meters high, including the exhaust chimney, weighs 25 tons and uses a filter surface area of 534 square metres to change around 85,000 cubic meters of air per hour. “We designed the filter system in such a way that it removes the dust from the Source One Plastics plant directly at the point of emission, i.e. where it is generated. This means that no deposits are deposits in the hall,” says Jens Konradi, Sales Manager at Schulz & Berger Luft- und Verfahrenstechnik GmbH. “Supporting a sustainable project with our filter technology, that plastics that are difficult to recycle in a way that conserves resources is a particular pleasure. The green idea drives us all.”
