In order to apply the concepts that allow the transition from a linear to a circular economy, waste generators and/or processors must identify those variants that generate products that can be used as secondary raw materials, thus also respecting the actions governing sustainable development. This paper presents such a variant, the briquetting of waste with high iron content, waste generated on current flows in steel enterprises or deposited in industrial sites. The obtained briquettes are analyzed for chemical and mechanical characteristics so that can be used as secondary materials in the steel production. An optimization of the chemical composition using generic algorithms is also proposed in order to obtain the mechanical characteristics necessary for the proper handling of these products.
为了应用那些能实现从线性经济向循环经济转变的理念,废弃物产生者和/或处理者必须识别出那些能产出可作为二次原材料使用的产品的变体,从而也要遵循可持续发展的相关行动准则。本文介绍了这样一种变体,即对高铁含量废弃物进行压块处理,这类废弃物产生于钢铁企业的生产流程中或堆积在工业场地。对所得压块进行化学和机械特性分析,以便其能在钢铁生产中用作二次材料。还提出使用遗传算法对化学成分进行优化,以获得妥善处理这些产品所需的机械特性。
