چکیده

در آینده نزدیک و با گران‌تر شدن هزینه انــرژی، کارخانه‌های بیشــتری تمایل دارند از زباله‌ها برای تولید انرژی استفاده نمایند. هزینه‌های دفن زباله در حال افزایش اســت و به طور فزاینده‌ای باعــث افزایش هزینه بازیافت می‌شود. از طرفی سوخت‌های جایگزین برای تولید سیمان کارآمد از نظر اقتصادی ضروری هستند. زباله‌ها، بسته‌بندی و سایر مواد می‌توانند جایگزین سوخت‌های فسیلی گران قیمت مانند زغال سنگ و نفت باشند. اما ابتدا باید آن‌ها را به سوخت با کیفیت بالا (RDF: Refuse Derived Fuel) تبدیل کرده و به طور ایمن در کارخانه‌ها نگهداری کرد. این وظیفه‌ای است شرکت‌های تولید سیمان با عضویت در ابتکار پایداری سیمان (CSI) و شورای جهانی تجارت برای توسعه پایدار (WBCSD) برای خود تعیین می‌نمایند. هدف جایگزینی منابع انرژی فسیلی گران قیمت مانند زغال سنگ، گاز و نفت در تولید و کاهش انتشار CO2 بوده است. این مطالعه دیدگاه‌های ارزشمندی را در مورد تولید RDF به‌عنوان یک جزء پایدار از یک سیستم مدیریت یکپارچه MSW، به ویژه برای کشورهای در حال توسعه، در جهت دستیابی به اهداف 17 گانه توسعه پایدار (17SGDs) و اقتصاد چرخشی ارائه می‌دهد. RDFمناسب نسبت به پسماند جامد شهری، ارزش حرارتی بالاتر، رطوبت، خاکستر، کلر، کوگرد و نیتروژن کمتری دارد.

چکیده [English]

In the near future and with the cost of energy becoming more expensive, more plants tend to use waste for energy production. The cost of landfilling is increasing and it is increasing the cost of recycling. On the other hand, alternative fuels are necessary for the production of efficient cement from an economic point of view. Wastes, packaging, and other materials can replace expensive fossil fuels such as coal and oil. But first, they should be converted into high-quality fuel (RDF: Refuse Derived Fuel) and stored safely in factories. This is a duty cement production companies set for themselves by being a member of the Cement Sustainability Initiative (CSI) and the World Business Council for Sustainable Development (WBCSD). The goal has been to replace expensive fossil energy sources such as coal, gas, and oil in production and reduce CO2 emissions. This study provides valuable insights into RDF production as a sustainable component of an integrated MSW management system, especially for developing countries, in order to achieve 17 SDGs (17 Sustainable Development Goals) and a circular economy. Suitable RDF has higher moisture, ash, chlorine, sulfur, and nitrogen content than LHV municipal solid waste.
