摘　　要：使用生命周期评价法,以三款"L"形厨柜为例,探究板式厨柜产品的碳足迹。发现板式厨柜在全生命周期碳排放中存在差异,国产双饰面门板厨柜全生命周期碳足迹为1002.204 kgCO_(2)eq,单面亚克力门板厨柜为630.41 kgCO_(2)eq,国产双饰面门板厨柜为621.346 kgCO_(2)eq。分析显示双饰面门板厨柜主要碳排放来自柜身和台面的原材料获取与加工,而膜压门板和单面亚克力门板厨柜的主要碳排放包括柜身和台面的原材料获取与加工、五金件的制造以及柜门的加工阶段。进一步的敏感度分析显示,18 mm双饰面颗粒板、运输环节以及各类台面石材对碳足迹的影响较大。基于研究结果,提出了板式厨柜产品的降碳建议,包括选择低碳足迹材料、减少进口台面使用、考虑太阳能板安装、建立废弃人造板和废弃台面石材的回收链、提高产品耐用性等。最后对企业提出了增设设备独立电表、建设原材料碳足迹统计系统、标示产品碳足迹认证标牌等优化建议。Using the life cycle assessment method,we took three"L"shaped kitchen cabinets as examples to explore the carbon footprint of panel kitchen cabinet products.It was found that there are differences in the full life cycle carbon emissions of panel kitchen cabinets.The full life cycle carbon footprint of domestic double-sided door panel kitchen cabinets is 1002.204 kgCO_(2)eq,single-sided acrylic door panel kitchen cabinets are 630.41 kgCO_(2)eq,and domestic double-sided door panel kitchen cabinets are 621.346 kgCO_(2)eq.The analysis shows that the main carbon emissions of double-sided door panel kitchen cabinets come from the acquisition and processing of raw materials for the cabinet body and countertops,while the main carbon emissions of film-pressed door panels and single-sided acrylic door panel kitchen cabinets include the raw material acquisition and processing of the cabinet body and countertops,and hardware.The manufacturing and processing stages of cabinet doors.Further sensitivity analysis shows that 18 mm double-faced particle board,transportation links and various types of countertop stones have a greater impact on the carbon footprint.Based on the research results,carbon reduction suggestions for panel kitchen cabinet products are put forward,including selecting low-carbon footprint materials,reducing the use of imported countertops,considering the installation of solar panels,establishing a recycling chain for waste artificial boards and waste countertop stones,and improving product durability.At the same time,optimization suggestions were put forward for enterprises to add independent electricity meters for equipment,build a raw material carbon footprint statistics system,and mark product carbon footprint certification signs.
