摘要

随着世界人口的增长和资源的消耗,全球废物生产和能源需求的增加:因此,可持续的废物管理战略很重要。这项工作的目标是研究泰国农武里省适当的RDF生产和垃圾填埋管理指南。对Nonthaburi垃圾填埋场产生的垃圾衍生燃料(RDF)进行了物理化学研究。为将LW生产为25吨/小时的RDF,实施了以下程序:(i)将LW放入预切碎机中,然后放入一级破碎机。(ii)使用磁力分离器从废物流中去除金属(iii)使用传送带将LW转移到动态圆盘筛,在那里可回收废物被分离成小于80mm的较小尺寸。;(iv)废物通过空气分离器以拒绝高密度材料(土壤和玻璃);(v) 手动分离不需要的材料,以及(vi)打包所需材料。RDF由78.16-67.93%的塑料、2.29-4.34%的橡胶、1.27%的木材、1.53-2.19%的纺织品和12.19-26.72%的其他(类土材料)组成。水分含量降低,热值增加到18.08-29.41MJ/kg。结果表明,高碳低氮适合于能源转换。分离可以有效地将LW转化为RDF,RDF可以作为替代燃料应用。。因此,RDF可以为更可持续和循环的经济做出贡献。

Solid waste management by RDF production from landfilled waste to renewable fuel of Nonthaburi
A worldwide increase in waste production and energy demand as the world's population grows and consumes more resources: therefore, sustainable waste management strategies are important.The goal of this work is to researchthe guidelines for the appropriate RDF production and landfill waste management of the Nonthaburi province, Thailand. Refuse Derived Fuel (RDF) produced from landfilled Waste (LW) in Nonthaburi was investigated the physicochemical. The following procedure has implemented for the production of LW to RDF of 25 tons/hr of LW: (i) the LW was placed in a pre-shredder, which was followed by a primary crusher. (ii) metals were removed from the waste stream using a magnetic separator (iii) the LW was transferred using a conveyor belt to a dynamic disc screen, where recyclable waste was separated into smaller sizes less than 80 mm.; (iv) the waste passed through an air separator to reject high-density materials (soil and glass); (v) the undesired material were separated manually, and (vi) the desired material were baled. RDF composition consisted of 78.16-67.93% plastics, 2.29 -4.34% rubber, 1.27% wood, 1.53-2.19 % textile, and other (soil-like material) 12.19-26.72%. The proximate and elemental analysis of RDF was determined according to the ASTM method. The moisture content was reduced, and the heating value increased to 18.08-29.41 MJ/kg. The results suggested high carbon and low nitrogen content suitable for energy conversion. The separation can effectively convert LW to RDF, which can apply as a alternative fuel.. Therefore, RDF can contribute to a more sustainable and circular economy.
