In their study, the researchers tested samples from both aerobic and anaerobic facilities, and also from a control facility that used only plant waste from a farm They found some amount of microplastics in all of the samples they tested except those from the control farm. They further found that the amount of microplastics depended on the process used at a given plant and that there tended to be more in the fertilizer from the aerobic facilities. They suggest microplastics wind up in biowaste due to their presence in foods, and also from being collected or stored in plastic containers. A team of researchers at the University of Bayreuth in Germany has found that microplastics that make their way into biowaste can show up in organic composts and fertilizers. In their paper published on the open access site Science Advances, the group describes their results when testing organic composts and fertilizers from several processing plants.
