Laboratory- and Prospective Industrial-Scale Life Cycle Inventories for Bio-Based Glycerol Trilevulinate Plasticizer

This repository contains comprehensive Life Cycle Inventory (LCI) data supporting the environmental assessment of glycerol trilevulinate (GT), an emerging plasticizer derived from bio-based glycerol and levulinic acid (Lenzi et al., 2023). The data covers two distinct production stages: an experimental laboratory-scale (13 g/batch) and a prospective industrial-scale (5 t/batch). Dataset Content The provided file includes the following sheets: GT_synthesis_lab_scale: life cycle inventories for the laboratory-scale synthesis of GT plasticizer (13 g/batch). GT_synthesis_industrial_scale: life cycle inventories for the prospective industrial scale production of GT plasticizer (5 t/batch). Calculations_GT_synthesis: mass balances, energy requirements, underlying assumptions and calculations related to both the laboratory-scale and the prospective industrial-scale scenarios. Liquid-liquid extraction: specific calculations for estimating solvent use during the extraction step at the industrial scale. LCI_GT_sensitivity_analysis: cumulative life cycle inventory dataset for prospective industrial-scale production of GT plasticizer under different assumptions (different LA:GLY ratio). DEHP_production_ind_scale: literature life cycle inventory data (Caldeira et al., 2023; Li et al., 2025) for the industrial-scale production of the fossil-based plasticizer di(2-ethylhexyl) phthalate (DEHP), used as a benchmark for the comparative LCA.本仓库包含完整的生命周期清单（Life Cycle Inventory, LCI）数据，用于支撑甘油三乙酰丙酸酯（glycerol trilevulinate, GT）的环境影响评价——该材料是以生物基甘油与乙酰丙酸为原料制备的新型增塑剂（Lenzi等人，2023）。 该数据涵盖两类截然不同的生产场景：实验室规模（13克/批次）的实验合成，以及工业规模（5吨/批次）的前瞻化生产。 数据集内容 所提供的文件包含以下工作表： GT_synthesis_lab_scale：GT增塑剂实验室规模合成（13克/批次）的生命周期清单数据。 GT_synthesis_industrial_scale：GT增塑剂前瞻工业规模生产（5吨/批次）的生命周期清单数据。 Calculations_GT_synthesis：与实验室规模及前瞻工业规模场景相关的物料衡算、能源需求、基本假设与计算过程。 液液萃取（Liquid-liquid extraction）：工业规模萃取环节溶剂使用量估算的专项计算。 LCI_GT_sensitivity_analysis：不同假设条件（不同LA:GLY投料比）下，GT增塑剂前瞻工业规模生产的累积生命周期清单数据集。 DEHP_production_ind_scale：以文献数据为支撑（Caldeira等人，2023；Li等人，2025）的化石基增塑剂邻苯二甲酸二(2-乙基己基)酯（di(2-ethylhexyl) phthalate, DEHP）的工业规模生产生命周期清单数据，用作对比生命周期评价（Life Cycle Assessment, LCA）的基准参照。
