Original MATLAB model for recycled carbon-fiber supply and demand
Year: 2026
Type: software
Abstract: This package contains the original MATLAB script for estimating recycled carbon-fiber supply from wind-turbine blades and potential carbon-fiber demand in Hong Kong. The source code is unchanged from the author-provided script; its filename has been simplified to rcf_supply_demand.m. The demand model uses 13 historical precursor inputs (2012–2024), converts them to potential CF demand for five adoption shares (5%, 6.25%, 7.5%, 8.75%, and 10%), compares ARIMA(2,1,2), ARIMA(1,1,0), and ARIMA(0,1,2) by the original in-sample RMSE rule, and forecasts 2025–2050. The historical plotted segment includes fitted values, and the shaded range represents adoption scenarios rather than a statistical prediction interval. The package includes execution instructions, tested MATLAB and toolbox versions, historical inputs, and selected verified outputs. Native MATLAB R2025b Update 2 reproduced the manuscript-rounded demand values of 165.7 t in 2030 and 267.7 t in 2050. The 2024 plotted fitted value is 96.4 t; the direct historical input conversion at 7.5% is 109.43 t. This release documents the original supply–demand model. It does not include the revised manuscript's complete climate-accounting, sensitivity-analysis, or economic-assessment code.
