Utilization of sorted secondary PET waste - raw materials in the context of sustainable development of the modern city

Abstract

Abstract It is established that the lack of technologies for the complete utilization of secondary PET – raw material sorted from municipal solid waste - raw materials is a threat to the sustainable development of the modern city. One of the promising ways of PET disposal is to use it to encapsulate mineral fertilizers. Under the laboratory conditions, the technology of PET modification and capsule application to mineral fertilizer particles under fluidized bed conditions has been successfully tested. Conducted pilot tests of the release of nutrition elements from mineral fertilizers encapsulated with modified PET, confirmed the uniformity and quality of the coating. Pilot studies have confirmed the effectiveness of the new form of obtained fertilizers.
