The forecasted bioplastic production capacity has signaled a strong growth in the next years, but with higher participation of drop-ins. Drop-in bioplastics are nonbiodegradable materials, identical to their fossil counterparts although obtained from renewable raw materials. The present paper examines why drop-ins have presented growth rates higher than non-drop-ins, analyzing some critical factors of their adoption by end users and whether the bioplastics tipping point has been reached. This comparison between drop-in and non-drop-in bioplastic innovation dynamics, which involves investment and complementary assets, will contribute to a better understanding of the critical factors that lead to bioplastics tipping point.
