Exploiter le « champ pétrolifère urbain » : Valoriser les déchets de films plastiques

Core Insights - The article discusses the transformation of plastic waste, specifically PP and PE films, into valuable fuel through advanced sorting technology and pyrolysis processes [1][4][5] Group 1: Industry Overview - Hundreds of millions of tons of lightweight materials, primarily PP and PE films, are found in construction and demolition waste, constituting about 50% of this waste [1] - Traditional sorting technologies fail to achieve high-purity separation of PP/PE films, leaving significant energy potential untapped for years [1][2] Group 2: Technological Advancements - The key to exploiting these "urban oil fields" lies in effective sorting technology, which can handle complex impurities such as PVC and PET films, wood chips, plastic waste, paper, and sand [2] - DATABEYOND's FASTSORT-FILM utilizes advanced AI databases and hyperspectral recognition to sort PP/PE films with over 95% accuracy, effectively removing harmful impurities [3] Group 3: Conversion Process - High-purity PP/PE films can be converted into pyrolysis oil through anaerobic thermal cracking, yielding 0.6 to 0.75 tons of oil per ton of film [4] - This process supports a sustainable cycle of waste-to-energy conversion and significantly reduces carbon emissions [4] Group 4: Environmental Impact and Opportunities - The concept of "urban oil fields" represents a green opportunity, with DATABEYOND's intelligent sorting technology facilitating breakthroughs in global energy transition and environmental protection [5] - By leveraging innovation, the industry aims to enhance the circular economy and promote sustainable development through collaboration and advanced solutions [5]
