The objective of this study was to address the limitations biodegradable plastics—low economic benefits and marketing difficulties. To end, analyzed production processes two plastics: polylactic acid (PLA) polybutylene adipate terephthalate (PBAT). Based on analysis, economic, technical, environmental improvement indicators were constructed, an optimization model with three objectives profit, carbon emission cost, process risk established. In study, we embedded improved NSGA-III algorithm obtain Pareto optimal solution set. We also proposed entropy-weighted efficiency index (EWEI) for analysis transport advantages based distribution plastics production, road density, regional prices. With a line capacity 10,000 tons 8% discount rate, 10-year return PBAT products 7,039,931.23 yuan higher than that PLA products. profit 488.92 per ton production. However, exhibited carbon-emission cost products, especially risk, by 0.11%. East China region has obvious geographical advantages, but Southwest is constrained in presence mountainous terrain. Therefore, it imperative optimize China’s overall industrial layout plastics, strengthen acquisition support sustainable promotion market, effectively minimize pollution caused traditional plastics.
